Abstract
The psyllid fauna of the “Parque Estadual Caminho dos Gerais” and its surroundings is described based on a recent survey.
We record twenty three species from the municipalities of Gameleiras, Mamonas, and Monte Azul from where no previous
records are known. Ten of the species are described, three are referred to described species with doubts due to insufficient
material and ten constitute undescribed taxa. One species is reported for the first time for the state of Mato Grosso do Sul and
another for Minas Gerais. Almost half of the species are widely distributed, but two species appear to be endemic to the
region. Fifteen species use Fabaceae as host, a pattern that reflects a general pattern in Psylloidea.
Keywords: Endemics. Jumping plant lice. New state records. Rock vegetation.

Resumo
A fauna de psilídeos do Parque Estadual Caminho dos Gerais e seus arredores é descrita com base em um levanta- mento
recente. Vinte e três espécies foram registradas nos municípios de Gameleiras, Mamonas e Monte Azul, de onde nenhum
registro anterior é conhecido. Dez das espécies são conhecidas, três são provisoriamente referidas como espécies descritas
devido ao material insuficiente e dez constituem táxons não descritos. Uma das espécies é relatada pela primeira vez para o
estados de Mato Grosso do Sul e outra para Minas Gerais. Quase metade das espécies estão amplamente distribuídas, mas duas
espécies parecem ser endêmicas da região. Quinze espécies estão associadas a Fabaceae, um padrão que reflete um padrão
geral em Psylloidea.

Introduction
Psyllids or jumping plant lice (Hemiptera: Psylloi-
dea) constitute a small group of phloem-feeding insects rich
in species mainly in the tropics and south temperate
regions.
Currently, over 4000 species have been described
worldwide
but it is estimated that there are as many still undescribed
(Burckhardt & Queiroz, 2020). Adults are always winged
and range from 1 to 10 mm in body length, including the
wings when folded over the body.
There are five instars of
immatures which usually develop
on one or a few related host
plant species (Hollis, 2004; Burckhardt et al., 2014). Often
related psyllid species develop on related plant species, with
preference for some plant families or orders (e.g. Fabaceae,
Myrtaceae, Asteraceae or Sapindales) whereas others are not
or
hardly used (Orchidaceae, Poaceae, Rubiaceae or Lamia-
ceae) (Ouvrard et al., 2015). Some psyllids are serious pests
of agricultural or forestry crop plants (Burckhardt, 1994;
Hollis, 2004; Hodkinson, 2009) for which a lot of literature is
available but very little is known about the biology,
phenology or distribution of a vast number of species. This
is particularly true for the Brazilian psyllids where only
around 150 species have been reported of a 1000 estimated
(Burckhardt & Queiroz, 2012, 2020;
Rendón-Mera et al., 2020; Burckhardt, 2021).

Qualitative sampling was carried out during three
full days with the aim to cover best the plant and habitat
diversity as well as the altitudinal range of the Park. The
psyllids were collected using a sweep net and aspirator as
described by Queiroz et al. (2017). The col-
lected specimens
are conserved dry mounted or stored in
70% ethanol. Psyllids
and plant vouchers are deposited in the Naturhistorisches
Museum Basel, Switzerland (NHMB). The classification
and nomenclature of Psyl- loidea follows Burckhardt et al.
(2021) and Ouvrard (2021). Plant names are cited according
to the Flora do Brasil (2021). Unpublished data based on
material from previous collections by D. Burckhardt and D.
L. Queiroz which is mostly deposited in the NHMB is
referred to as “unpublished NHMB data”
The “Parque Estadual Caminho dos Gerais” was
created in the state of Minas Gerais, Brazil in 2007, with an
area of over 56 thousand hectares, belonging to the
municipalities of Espinosa, Gameleiras, Mamonas and
Monte Azul. A major reason to create the park was that the
“Serra Geral” (a mountain range), where the State
Park is
located, contains areas of extreme biological impor-
tance, with
the presence of rare, endemic or endangered species and a
high species richness in various groups of organisms. This
unique biodiversity was threatened by the increased human
activities. A strong pressure on the natural park
environment, especially in the plateau areas, put some
animal and plant species in danger of extinction and even
caused the disappearance of water courses. Thanks to the
protection, many disturbed areas are recovering now and
other areas are protected from further destruction
(Maioambiente.MG, 2007).
Results
Twenty three species of Psylloidea were collected in
and around the “Parque Estadual Caminho dos Gerais”.
Ten of
the species belong to described species, three are referred
to described species only provisionally for the lack of
sufficient material and 10 species represent undescribed
taxa.
Since its creation, no faunistic surveys have been
carried out in the park, and no psyllids have been reported
from
the three municipalities. Inventories are an impor- tant base
for further scientific research and constitute a useful tool in
management decisions. Here we report on a study of the
psyllid fauna of the “Parque Estadual Caminho dos Gerais”
and its surroundings.

Diversity of psyllids and their host plants (Hemiptera: Psylloidea) from the “Parque Estadual Caminho dos Gerais” and surroundings, Minas Gerais, Brazil
med hosts are Hymenaea spp. (Fabaceae) on whose leaves the
immatures often induce roll galls and produce lots of flocculent
wax. The psyllid is found in Cerrado vegetation,
transitional
Cerrado–Amazon forests and gallery forests (Burckhardt &
Queiroz, 2020). Apsyllopsis mexicana is widely distributed
and one of three species listed here
which also occurs outside
Brazil. We found only relatively
few specimens suggesting a
low population level at the time of our survey of this usually
common species.
This species was collected also in other localities in
MG and RJ (unpublished NHMB data) in Cerrado vege-
tation
and Atlantic forest. Immatures develop in shallow pit galls
usually on the abaxial leaf surface (Figure 1). In locality #6,
a sapling of about 3 m height, lacking flowers or fruits, was
heavily infested. Most leaves were
densely covered in the
psyllid galls (Figure 2). Kielmeyera
(Calophyllaceae) is an
atypical host as the majority of
Calophya species develops on
members of the Sapindales
(Burckhardt & Basset, 2000;
Mendez et al., 2016).
Calophya
sp.
(Calophyidae, Calophyinae). Mate- rial
examined: Monte Azul: #6: 21 ♂, 31 ♀, 85 immatures,
Kielmeyera sp.; #7: 2 ♂.
Figures 1, 2 – Galls of Calophya sp. on leaves of Kielmeyera sp. (Calophyllaceae). – 1: Detail of abaxial face (left); 2: infested
sapling in locality #6 (right).
Caradocia longiantennata
White & Hodkinson,
1980
(Psyllidae, Ciriacreminae). Material examined: Mon-
te Azul:
#5: 1 ♂, 1 ♀, Tapirira guianensis. – Gameleiras: #10: 6 ♂, 8
♀, Tapirira guianensis.
This is one of several undescribed Caradocia
species recently found in Brazil (unpublished NHMB data).
Immatures develop on new flush and leaves of Tapirira
obtusa (Anacardiaceae) in the same habitats as Caradocia
longiantennata.
Reported from Brazil (BA) (Burckhardt & Queiroz,
2012); new record for MG. Recent collections made in
Brazil (unpublished NHMB data) suggest that the species
has a
much wider distributed in Brazil but a taxonomic
revision is
necessary to separate it accurately from several
morphologically similar, undescribed species. Immatures
are
free living on new flush and leaves of Tapirira guia-
nensis
(Anacardiaceae) in Cerrado vegetation and gallery
forests
(unpublished NHMB data).
Ceropsylla pouteriae
Burckhardt, in Oliveira et
al.,
2019 (Triozidae). Material examined: Monte Azul: #7: 74
immatures, Pouteria ramiflora.
Reported from Brazil (MG) (Oliveira et al., 2019). The
species was previously known only from Uberlândia,
the
material from Monte Azul representing the second record.
Immatures induce deep pit galls on the leaves of
Pouteria
ramiflora (Sapotaceae) (Figures 3, 4) in Cerrado
vegetation
(Oliveira et al., 2019).
Caradocia
sp.
(Psyllidae, Ciriacreminae). Ma-

Heteropsylla
sp.
(Psyllidae, Ciriacreminae). Ma-
terial
examined: Monte Azul: #5: 9 ♂, 4 ♀, Calliandra
mucugeana.
This is an undescribed Heteropsylla species re-
sembling H. boquetensis (Brown & Hodkinson, 1988) in
the presence of short genal processes and the digiti- form
paramere. Only adults were found on Calliandra
mucugeana (Fabaceae) suggesting this is a host, though
immatures are necessary for confirmation. Adults and
immatures of the same species were found in the Parque
Estadual Rio Preto (MG, São Gonçalo do Rio Preto) on
Calliandra fasciculata (unpublished NHMB data). Despite
intesive search on various Calliandra species also in other
localities, we could not find the species elsewhere. The
species seems endemic to northeastern Minas Gerais and
restricted to rock habitats.
Isogonoceraia
sp.
(Psyllidae, Ciriacreminae).
Material examined: Monte Azul: #1: 15 ♂, 13 ♀, 22
immatures, Chamaecrista brachystachya; #4: 45 ♂, 61
♀, 9 immatures, Chamaecrista brachystachya; #5: 1 ♀,
1 immatures.
This is an undescribed species differing from its
congeners in the dark forewings. It has been collected also
in BA (Mucugê) and MG (Diamantina, São Gonçalo do Rio
Preto) (unpublished NHMB data). Immatures develop on
the flower buds and new flush of Chamae- crista
brachystachya (Fabaceae) (Figure 5) and other
Chamaecrista species. It is restricted to rocky habitats
and
probably endemic to the mountains of southwestern
Bahia and
north-eastern Minas Gerais.
Colophorina tupi
Burckhardt & Queiroz, 2020
(Psyllidae, Macrocorsinae).
Material examined: Monte Azul: #5: 1 ♂, 1 ♀,
Copaifera sp.
Figure 5 – Immatures and adults of Isogonoceraia sp. on
flowers and pedicels of Chamaecrista stachya
(Fabaceae).
Reported from Brazil (BA, GO, MG, MS, MT, PR,
SP) (Burckhardt & Queiroz, 2020). Immatures induce rolls
on the leaves of Copaifera langsdorffii (Fabaceae) in which
they develop. The species can be found in a va- riety of
habitats such as Cerrado vegetation, transitional
Atlantic/Cerrado forests or gallery forests.
Heteropsylla
cf.
caldwelli
Burckhardt, 1987
(Psyllidae, Ciriacreminae). Material examined: Monte
Azul: #5: 1 ♀. – Mamonas: #8: 1 ♀.
Reported from Argentina, Brazil (GO, MG, MT,
PR, RS, SP), Colombia, Costa Rica, Panama, Paraguay and
Trinidad (Muddiman et al., 1992, Machado et al., 2017,
Barreto et al., 2020). Heteropsylla caldwelli is wi- dely
distributed also outside Brazil. Immatures develop
on new
growth of Albizia spp., Anadenanthera colubrina,
A. peregrina var. falcata, Enterolobium contortisiliquum,
E. cyclocarpum and Senegalia polyphylla (Fabaceae) in a
variety of habitats (Muddiman et al., 1992).
Jataiba uncigera
Burckhardt & Queiroz, 2020
(Psyllidae, Ciriacreminae). Material examined: Monte
Azul: #5: 1 ♂, 1 ♀, Copaifera sp. Reported from Brazil
(MG, MS, PR, SP) (Burckhardt & Queiroz, 2020). Imma-
tures develop on the leaves of Copaifera langsdorffii (Fa-
baceae). The species can be found in a variety of habitats
The two females at hand are referred to Hete-
ropsylla caldwelli with doubts as males are required for a
correct species identification.

such as Cerrado vegetation, transitional Atlantic/Cerrado
forests or gallery forests.
(CE, GO, MG) (Burckhardt & Queiroz, 2020). Immatures
develop on leaves of Hymenaea species (Fabaceae) in
Cerrado vegetation. The single female at hand is referred
to
Platycorypha scalprata with some doubt as males are
required for a correct identification.
Leurolophus oriformae
Burckhardt & Basset,
2000
(Aphalaridae, Rhinocolinae). Material examined:
Monte
Azul: #6: 1 ♂, Lithraea brasiliensis. Reported from
Argentina,
Brazil (MG, PR, RS, SC, SP) (Burckhardt & Queiroz, 2012;
Marsaro et al., 2021) and Uruguay. The species was also
found in Mato Grosso do Sul (munici- pios Bandeirantes,
Campo Grande, Jardim, Rochedo, Sidrolândia)
(unpublished NHMB data) representing a new state record.
Immatures develop on the leaves of Lithraea spp.
(Anacardiaceae) in Cerrado vegetation, Atlantic forests or
gallery forests.
Platycorypha
sp.
(Psyllidae, Platycoryphinae).
Material examined: Monte Azul: #1: 1 ♂, Tachigali sub-
velutina; #3: 1 ♂, Tachigali subvelutina; #4: 1 ♂, 1 ♀.
– Mamonas: #8: 1 ♂, Tachigali subvelutina; #9: 2 ♀,
Tachigali subvelutina. This is an undescribed species as-
sociated with Tachigali subvelutina (Fabaceae) which
probably occurs also in other places in MG (unpublished
NHMB data). The new species belongs to a complex of
morphologically similar species developing on Tachigali
species. A taxonomic revision of the group is needed to
define the species, their distribution and host ranges.
Immatures are free-living on the leaves of their host and occur
in Cerrado vegetation.
Mitrapsylla copaiferae
Burckhardt & Queiroz,
2020
(Psyllidae, Ciriacreminae). Material examined: Monte Azul:
#3: 1 ♂, unidentified Fabaceae; #5: 1 ♂, 1
♀, Copaifera sp.; #6: 1 ♀; #7: 1 ♂. Reported from Brazil
(GO, MG, MS, MT, SP) (Burckhardt & Queiroz, 2020).
Immatures develop on the leaflets of Copaifera spp. (Fa-
baceae) in Cerrado vegetation and Atlantic forests.
Queiroziella
sp. 1
(Psyllidae, Ciriacreminae).
Material examined: Monte Azul: #5: 10 ♂, 24 ♀, 9 imma-
tures, Mimosa sp.; #7: 21 ♂, 31 ♀, 3 immatures, Mimosa
sp. – Mamonas: #8: 3 ♂, 8 ♀, 3 immatures, Mimosa sp.
Mitrapsylla gloriae
Burckhardt & Queiroz, 2020
(Psyllidae, Ciriacreminae). Material examined: Mon- te
Azul: #1: 56 ♂, 48 ♀, unidentified Fabaceae; #2: 1
♀;#3: 27 ♂, 18 ♀, unidentified Fabaceae; #4: 10 ♂, 18
♀, Copaifera sp.; #5: 8 ♂, 9 ♀, Copaifera sp.; #7: 8 ♂,
13 ♀. – Mamonas: #8: 2 ♂, 2 ♀; #9: 1 ♂. – Gameleiras: #10:
4 ♂, 3 ♀, Copaifera sp. Reported from Brazil (DF,
GO, MG,
MS, MT, PR, RJ, SC, SP) (Burckhardt & Queiroz,
2020).
Immatures develop on the leaflets of Copaifera spp.
(Fabaceae) in Cerrado vegetation, Atlantic, Arauca- ria and
gallery forests. This is one of the most common psyllid
species in this area and adults are often found on non-host
plants.
Queiroziella was erected for five species from
southern Brazil on Mimosa scabrella (Fabaceae) and one
species from Paraguay on an unidentified Mimosa species
(Burckhardt, 2021). Apart from the six described species,
there
are many undescribed species in Brazil developing mostly on
Mimosa species. This and the following two
species
represent undescribed taxa, each morphologically
distinct and
associated with different Mimosa species. Queiroziella sp. 1
resembles Q. borealis (Burckhardt, 1987) in the falcate
paramere but differs in details of the male and female
terminalia (Figure 6) and the host association.
Mitrapsylla periandrae
Rendón-Mera et al.,
2020
(Psyllidae, Ciriacreminae). Material examined: Monte Azul:
#5: 1 ♂. Reported from Brazil (GO, MG, PR, SP) (Rendón-
Mera et al., 2020). Immatures deve- lop on new flush of
Periandra mediterranea (Fabaceae) in a variety of habitats
such as Cerrado vegetation and Atlantic, Araucaria and
gallery forests.
Queiroziella
sp. 2
(Psyllidae, Ciriacreminae).
Material examined: Mamonas: #8: 15 ♂, 10 ♀, 5 imma-
tures, Mimosa sp.; #9: 13 ♂, 45 ♀, 8 immatures, Mimosa sp.
See comment under Queiroziella sp. 1. Queiroziella sp. 2
differs from congeners in the apically incised paramere
(Figure 7) and the host association.
Mitrapsylla pterodontis
Rendón-Mera et al. 2020
(Psyllidae, Ciriacreminae). Material examined: Monte
Azul:
#1: 10 ♂, 7 ♀, unidentified, Fabaceae; #5: 1 ♂; #7:
1 ♀. –
Gameleiras: #10: 1 ♀. Reported from Brazil (BA, DF, GO,
MG, MS, MT, PR, SC, SP) (Rendón-Mera et al.,
2020). Pterodon emarginatus (Fabaceae) is a likely host but
needs confirmation. The species occurs in Cerrado
vegetation and Atlantic forest.
Queiroziella
species 3
(Psyllidae, Ciriacreminae).
Material examined: Monte Azul: #1: 21 ♂, 19 ♀, Mimosa
sp.;
#3: 42 ♂, 57 ♀, 3 immatures, Mimosa sp.; #4: 4
♀; #5: 20 ♂, 25 ♀; Mimosa sp. – Mamonas: #8: 1 ♂, 3
♀, Mimosa sp.; #9: 30 ♂, 28 ♀, 1 immatures, Mimosa sp. –
Gameleiras: #10: 1 ♂, 3 ♀. See comment under
Queiroziella species 1. Queiroziella species 3 differs from
congeners in the digitiform paramere, the short, apically
truncate female subgenital plate and the very short ca-
pitate setae on the caudal plate of immtures (Figure 8) and
the host association.

Trioza
sp.
(Triozidae). Material examined: Ga-
meleiras: #10: 10 ♂, 10 ♀, 2 immatures, Calophyllum
brasiliense. This is an undescribed species of the large,
polyphyletic genus Trioza. Immatures live on the leaves
of
Calophyllum brasiliense (Calophyllaceae) without indu- cing
any visible deformation. So far, no Brazilian triozids
have
been reported from Calophyllum (Calophyllaceae)
(Burckhardt & Queiroz, 2012).
dings confirms this. Of the 23 species, 11 (Apsyllopsis
mexicana, Colophorina tupi, Heteropsylla cf. caldwelli,
Jataiba uncigera, Leurolophus oriformae, Mitrapsylla copai-
ferae, M. gloriae, M. periandrae, M. pterodontis, Triozoida cf.
ingens and genus species) are widely distributed, i.e.
they
have been reported also from outside Brazil or from
more than
three states in Brazil. All these species are described taxa,
except for a one developing on Duguetia
furfuracea,
representing an undescribed genus and species of
Platycoryphinae. Of six undescribed species (Caradocia sp.,
Platycorypha sp., Queiroziella spp. 1–3 and Trioza sp.)
and
Caradocia longiantennata, all in need of taxonomic
revision, not much is known about the distribution. One
species is moderately widely (Platycorypha cf. scalprata:
reported from three states) and of two narrowly distribu- ted
(Calophya sp. and Ceropsylla pouteriae: reported from
one
state); two of the three species represent described
taxa. Two
species (Heteropsylla sp. and Isogonoceraia sp.)
appear to be
endemic to the mountains of northeastern Minas Gerais and
adjacent areas in Bahia, reflecting the narrow distribution of
their hosts.
Triozoida
cf.
ingens
Burckhardt, 1988 (Triozi- dae).
Material examined: Monte Azul: #7: 1 ♀. Reported
from
Brazil (MG), Panama and Paraguay (Burckhardt & Queiroz,
2012). Adults have been collected on Pimenta species
(Myrtaceae) which is a possible host. The single female at
hand is referred to Triozoida ingens with some doubt as
males are required for a correct identification.
Genus sp.
(Psyllidae, Platycoryphinae). Material
examined: Monte Azul: #1: 1 ♀, Duguetia furfuracea; #3: 1
♂, 2 ♀, Duguetia furfuracea; #4: 1 ♀;#7: 1 ♂, 5
♀, Duguetia furfuracea. – Mamonas: #9: 10 ♂, 15 ♀, Du-
guetia furfuracea. – Gameleiras: #10: 1 ♂, 2 ♀, Duguetia
furfuracea.
Fourteen species are monophagous, one is widely and
eight species are narrowly oligophagous. Host plants
of 15
species are Fabaceae, of three species Anacardia- ceae, of
two Calophyllaceae and of each one species Annonaceae,
Myrtaceae and Sapotaceae, respectively. According to an
analysis of Ouvrard et al. (2015), the Fabaceae represents
the family with the largest number of psyllid hosts, followed
by Myrtaceae and Asteraceae. The almost total absence of
psyllids associated with the last two families in the material
at hand is, therefore, somewhat surprising.
This is an undescribed genus of Platycoryphinae
with
one undescribed species developing on Duguetia furfuracea
(Annonaceae). The immatures are free-living on the leaves
and secrete sticky honeydew. The species has also been
found in other localities in MG as well as in GO, MS and
MT in Cerrado vegetation (unpublished NHMB data).
Discussion and conclusion
With 161 reported species (Burckhardt & Queiroz,
2012, 2020, 2021; Rendón-Mera et al., 2020; Burckhardt,
2021), the psyllid fauna of Brazil is poorly known. The
large percentage of undescribed species (43%) found in the
“Parque Estadual Caminho dos Gerais” and surroun-
Considering the very limited time of our survey, it is
hardly representative for the existing psyllid fauna of the
