Family Monophlebidae Signoret 1875 Genus Perissopneumon Newstead 1900

Perissopneumon Newstead 1900

Type species: Perissopneumon ferox Newstead 1900 . Drosichiella Morrison 1927 (synonym)

Type species: Monophlebus tamarinda Green 1908 .

Generic diagnosis: The definition of the genus Perissopneumon is nebulous due to lack of a real comprehensive understanding of the genus and its comparative status. Based on the available descriptions of five species and notes on the genus by Newstead (1900), Green (1923), Morrison (1927 1928), Takahashi (1942), Rao (1950) and most recently by Gavrilov-Zimin (2018), the generic characters of adult female may be summarized as: abdominal spiracles dorsal, numbering 7 pairs, each with prominent band of disk pores within atrium; thoracic spiracle each with a band of wax pores on the collar or just around the opening; antennae eight segmented, stout, the terminal segment longest; derm with circular to oval areoles around each pores and setal bases; multilocular pores each with a single central loculus and mostly 4–8 peripheral loculi; ventral cicatrices, if present, large, 1 or 3 in number, closely associated in a defined area situated posterior to vulva; anal opening sclerotized, with a band of wax pores.
