New records, and nomenclatural and biological notes on Reduviidae (Hemiptera: Heteroptera) from Bolivia and Brazil Author Gil-Santana, Hélcio R. text Zootaxa 2008 1785 43 53 journal article 10.5281/zenodo.182460 a064f486-4831-4bd3-80c8-c0465baf2b3b 1175-5326 182460 Notocyrtus Burmeister, 1835 The genus Notocyrtus was recently revised by Carvalho & Costa (1992 , 1993 ) and has 23 valid species (Costa & Gil-Santana 2001; Gil-Santana & Costa 2001). Notocyrtus spp. have been recognized as mimetic to meliponine bees. The mimicry is enhanced mainly by the angular inflated pronotum ( Haviland 1931 ; Jackson 1973). Nevertheless, only a single mimetic pair was specifically indicated: Trigona fulviventris Guérin, 1835 as a model of Notocyrtus dorsalis (Gray, 1832) (Jackson 1973) . The function of the mimicry, whether aggressive or defensive, is unknown, whereas the feeding habits already observed included sipping nectar or honey-dew from Homoptera colonies ( Haviland 1931 ; Jackson 1973). FIGURES 1–4. Brontostoma basalis , dorsal view, 1, female; 2, male; Fig. 3. Daraxa carnifex , male, lateral view; Fig. 4. Pseudozirta schaeferi , female, dorsal view. Original observations made with two females of Notocyrtus fungosus Stål, 1859 at Nova Friburgo ( 22º 16’ S ; 42º 34’ W , 1090 m . a. s. l.), Rio de Janeiro State, Brazil , demonstrated that they were not interested in Meliponini bees, but actively fed on Nematocera Diptera offered to them ( Figs. 10–11 ). FIGURES 5–9. Heza gilsantanai , female, 5, dorsal view; 6, head and pronotum; 7, abdomen, lateral view; 8–9, apex of abdomen, 8, ventral view; 9, posterior view. There is no published description of the immature forms of Notocyrtus spp. A last instar of N. fungosus showed that the pronotum only become inflated in adult of this species a few hours after ecdysis ( Figs.12–13 ).
