RESUMO

Cladomorphus petropolisensis sp. nov., a new species of stick insect from Petrópolis, Rio de Janeiro, Brazil, is herein described and compared to the other sympatric species, C. phyllinus Gray, 1835 (Phasmatidae, Cladomorphinae). The description of the new species is supported by morphological and molecular evidence. Kimura-2-parameter (K2P) intraspecific COI divergences among the holotype of C. petropolisensis sp. nov. and C. phyllinus individuals ranged from 2.9% to 4.4%, which are suggestive of distinct species, especially when considering that all Cladomorphus individuals studied were collected in the Petrópolis municipality. The new species can be distinguished from C. phyllinus Gray, 1835 by several characteristics: smaller size, the presence of two spines on the hind femora, the relative longer length of the ovipositor, and spiny tegument, especially in the mesonotum, sculpturing of the operculum of the egg.

RESUMO

We present new information on the poorly known genus of stick insects, Canuleius Stål, 1875, with redescriptions of two Brazilian species, Canuleius grandis Toledo Piza, 1936 and Canuleius sanguinolentus (Brunner von Wattenwyl, 1907) comb. nov., the latter herein transferred from Bacteria Berthold, 1827. Type material of both species was examined, as well as additional specimens recently collected and deposited at the Museu de Zoologia da Universidade de São Paulo (MZUSP). The types of two other species in the genus, Canuleius affinis Toledo Piza, 1936 and Canuleius brevipes Toledo Piza, 1936, were also examined and both species are herein synonymised under C. grandis (syn. nov.). The study includes the first descriptions of the male of C. grandis, the female of C. sanguinolentus and the eggs of both species, which are the first descriptions of eggs of Canuleius. Some notes are presented on the biology of both species, including the first observations of mating and oviposition in Heteronemiidae. Taxonomic aspects of Canuleius are discussed.

RESUMO

The new genus Andeocalynda n. gen. is described and the supposed relationships are discussed. The genus is restricted to the mountainous Andean regions of Ecuador and Colombia. Nine new species are described and illustrated: A. aspericollis n. sp., A. banosense n. sp., A. brevicercata n. sp. and A. lojaense n. sp. from Ecuador based on the males only, A. decorata n. sp., A. mutica n. sp., A. densegranuloa n. sp. and A. tuberculata n. sp. from Ecuador as well as A. putumayoense n. sp. from Colombia based on the male and female. The eggs of the two new Ecuadorian species A. decorata n. sp. and A. tenuis n. sp. are described and illustrated. Two species, previously attributed to other genera are transferred to Andeocalynda n. gen., this is: A. carrikeri (Hebard, 1919) from the genus Bacteria Berthold, 1827 (n. comb.) and A. comis (Bates, 1865) from the genus Clonistria Stål, 1875 (n. comb.). As a result, Andeocalynda n. gen. currently includes eleven known species.

RESUMO

We describe a new species of Pachyphloea from the Natural National Park (NNP) Chicaque, Cundinamarca in the Colombian Andes, providing data on the structure and variability of its eggs. In addition, we synonymize Grylloclonia n. syn. under Pachyphloea, and provide a key for distinguishing males and females of the known species. Finally, we discuss the taxonomical delimitation of genera within the tribe Xerosomatini, and highlight the necessity of carrying out additional studies in this particular taxon of stick insects.

RESUMO

A revised, geo-referenced, and cross-referenced list of 270 termite type localities in South America is presented. A total of 543 nominal species-group extant taxa are listed, 442 of them valid and 97 synonyms. The type-locality comprising the greatest number of nominal taxa in South America is Kartabo, Guyana (A.E. Emerson study site), with 59 taxa, followed by Cuiabá, Brazil (F. Sivestri), with 34, and Ribeirão Cascalheira, Brazil (Xavantina-Cachimbo Expedition, A.G.A. Mathews) with 26.

RESUMO

The neotropical genus of stick insects, Phantasca Redtenbacher, 1906, was recently revised by Hennemann et al. (2018). However, the females and eggs of several species remain unknown, including all five species recorded from Brazil. The female and egg of Phantasca phantasma (Westwood, 1859) are here described for the first time, based on material available at the Museu de Zoologia da Universidade de São Paulo, Brazil (MZSP). A set of measurements of males is also given, in addition to the measurements of the holotype presented in Hennemann et al. (2018). This complement to the description of P. phantasma is particularly important because it is the type species of the genus (designated by Zompro, 2001), therefore providing additional grounds for future taxonomic decisions involving Phantasca.

RESUMO

Isagoras aurocaudata sp. nov. is being described from two female specimens from the States of Minas Gerais, Brazil. Diagnostic characters for the new species are the yellowish compound eye with brown spots, the yellowish spot at basal third of tegmina and the yellowish abdomen segments 8-11. Furthermore, Isagoras aurocaudata sp. nov. is compared to species of Isagoras Stål and Planudes Stål.

RESUMO

Insects exhibit three patterns of gas exchange: continuous (CoGE), cyclic (CGE) and discontinuous (DGE). In this work, we present the first record of a DGE in Phasmatodea and its transition to CGE and to CoGE through a thermal gradient. The rate of CO2 production (VCO2) at 10, 20 and 30°C was examined in adults of Agathemera crassa, a high-Andean phasmid of central Chile. Carbon dioxide release was recorded during 24 h with L:D cycle of 12:12 h in order to record both rest and activity periods. At rest, A. crassa showed three patterns of gas exchange, highlighting the use of DGE preferably at 10°C. As the temperature increased, the CoGE pattern was more frequent being the only pattern observed in all individuals at 30°C. During activity, patterns changed to CoGE with a significant increase in VCO2. Our results support the idea that gas exchange patterns in insects are not distinct but correspond to a continuum of responses addressed by metabolic demand and where DGE can be expressed only under an absolute state of rest. Our results support the idea that the presence of the DGE may be underestimated in other insect taxa because they may have been measured under conditions where this pattern not necessarily can be expressed.

RESUMO

Cladomorphus trimariensis sp. nov. é descrita de Três Marias, Minas Gerais. A nova espécie difere de C. phyllinus Gray, 1835 principalmente pelo opérculo e placa micropilar do ovo, ausência de espinhos nas pernas médias e posteriores e pelas projeções distais nos tergos IV e V, que são menos desenvolvidas.

Cladomorphus trimariensis sp. nov., from Três Marias, Minas Gerais, is described and illustrated. The new species is different from C. phyllinus Gray, 1835 mainly for the operculum and micropylar plate of egg, absence of spines on the mid and hind legs, for the preopercular organ and distal projection of terga IV and V, that are less developed.
