Epirhyssa amazonica Mocsary 1905

( Fig. 2 D)

Diagnosis. This species can be distinguished from all other Neotropical Epirhyssa by the combination of the following characters: 1) margin of clypeus strongly convex; 2) propodeum short and finely granulate with dense long setae; 3) tergite I polished with fine wrinkles; and 4) mesoscutum with transverse rugae discontinuous and rounded.

Variation. Three specimens from Peruvian Amazonia show variation in coloration: lime yellow and black instead of pale yellow and brownish pattern of the paratype. Although the pattern is similar and structurally there are no clear differences with the paratype studied, this variation makes us consider the possibility of re-examining the identification of these specimens in the future when more material is available.

Distribution. Bolivia; Brazil; Peru.

Material examined. Paratype: Female ( FSCA) Bolivia, Santa Cruz, Buena vista, 12.VII.1972 Porter & Stange.

Peru: Female ( ZMUT) Dept. of Madre de Dios, Los Amigos, 278 m., Isrrael Gómez leg Malaise trap, 14–21.VIII. 2008. Female ( ZMUT), Dept. Loreto, Reserva Nacional Allpahuayo Mishana, 3°58’29” S, 73°25’46” W, 124 m., Sääksjärvi et al. leg., Malaise D2/ 3. X.1998. Male ( ZMUT): Dept. of Madre de Dios, Los Amigos, 278 m., Isrrael Gómez leg., Malaise, 14–21.VIII. 2008.

Biological notes. This species seems to be well distributed in lowland Amazonia and is recorded for the first time from Peru.
