Abstract

Quasigraptocleptes maracristinae gen. nov., sp. nov. ( Hemiptera , Heteroptera , Reduviidae , Harpactorinae , Harpactorini ) is described based on male and female specimens from Brazil. Photographs and comments about the syntypes of Myocoris nigriceps Burmeister, 1835, Myocoris nugax Stål, 1872, Myocoris tipuliformis Burmeister, 1838 and Xystonyttus ichneumoneus (Fabricius, 1803) are presented. The intra-specific variability and sexual dimorphic characteristics among specimens of Q. maracristinae sp. nov. are recorded. General characteristics of Hiranetis Spinola, 1837, Graptocleptes Stål, 1866, Quasigraptocleptes gen. nov. and Parahiranetis Gil-Santana, 2015, which seem to be closer genera, are compared, including those of the male genitalia of some species. A key to the species of Myocoris Burmeister, 1835, and an updated key to Neotropical wasp-mimicking Harpactorini genera are provided.

Study of the external female genitalia of 14 Rhodnius species (Hemiptera, Reduviidae, Triatominae) using scanning electron microscopy

João da Rosa, Vagner Mendonça, Sueli Gardim … (2014)

Background Among the vectors of Chagas disease (Hemiptera: Reduviidae:Triatominae), there are eighteen Rhodnius species described and some are difficult to identify. The aim of this article is to contribute to the specific identification of fourteen Rhodnius spp. through morphological characters of the external female genitalia. Methods Female abdomens were cut transversely. The specimens were then prepared for examination by using scanning electron microscopy. Results The careful examination of the dorsal, posterior and ventral sides revealed characteristics that allowed the identification of each of the fourteen species. Conclusion The use of external female genitalia as characteristics are proposed as a tool for specifically identifying Rhodnius species, and an identification key for these species is presented.

Characterization of the external female genitalia of six species of Triatominae (Hemiptera: Reduviidade) by scanning electron microscopy

João Aristeu da Rosa, Vagner Mendonça, Cláudia Rocha … (2010)

By macroscopic and microscopic dorsal side observation, it was noted that the IX and X segments of two species each of Panstrongylus and Triatoma terminate in an elongated way, whereas they terminate abruptly in the two species of Rhodnius. Scanning observation of the dorsal, ventral, lateral and posterior sides of the female genitalia of Panstrongylus herreri, Panstrongylus megistus, Rhodnius colombiensis, Rhodnius prolixus, Triatoma infestans and Triatoma vitticeps revealed that these six species are generally and specifically distinguished based on these elements. We describe several components that distinguish P. herreri from P. megistus: four on the dorsal side: the VII, VIII, IX and X segments, on the ventral view, three: VII sternite, VIII gonocoxite and VIII gonapophyse, on the lateral view one character, VIII gonocoxite and on the posterior view three characters: VIII and IX gonocoxite and XI gonopophyse. Comparing R. colombiensis and R. prolixus, there were three distinct characters on the dorsal side: the VII, VIII and X segments, on the ventral view three characters: the IX and X segments and VIII gonocoxite and on the posterior view four characters: the VIII, IX, X segments and VIII gonapophyse that distinguish the two species. T. infestans and T. vitticeps have four different characters on the dorsal side: the VII, VIII, IX and X segments, on the ventral view four characters: the VII and X segments, VIII gonocoxite and VIII gonapophyse, on the lateral view two characters, IX and X segments and on the posterior view four characters: the IX and X segments, VIII gonocoxite and VIII gonapophyse that distinguish the two species. Examination of the external female genitalia of six triatomine species by scanning suggests that these components are useful for taxonomical studies.
