Similsciophila gen. nov.
Type species: Similsciophila singularis sp. nov.
Species included: Similsciophila singularis sp. nov. and Similsciophila sinuata sp. nov.
Diagnosis
Body medium-sized, covered with long and dense pubescence. Mesonotum convex. Scutellum sharp and clearly projecting. Forewing Sc elongate, shorter than one-half of wing length; sc-r situated distinctly basal to Rs origin, arising near midway between h to Sc ending at margin; cell r distinctly large, longer than one-sixth of wing length; Rs furcated distad to fork of M 1+2; bRs longer than r-m; R 1 slightly curved; both R 1 and R 4+5 divergent terminally; R 4+5 arched near its mid-length; stem of M not developed and thin; M 1+2 furcated slightly distad to level of Sc ending. Tibiae and tarsi with short sparse setae.
Etymology
The generic name is derived from the Latin (simil -), in reference to similar, and sciophila is from the generic name Mesosciophila .
Remarks
Based on the venation, Similsciophila gen. nov. is distinguished from Mesosciophilopsis Blagoderov, 1993 and Jurasciophila Li and Ren, 2009 by the following characters: wing longer and wider; cell r distinctly larger, and longer than one-sixth of wing length. The new genus is similar to the genus Paramesosciophilodes Zhang, 2007 , but differs mainly by bRs longer than r-m. It also differs from Mesosciophilina Kovalev, 1985 , Mesosciophilodes Rohdendorf, 1946 and Mesosciophila Rohdendorf, 1946 in that R 4+5 arched near its mid-length.
Distribution
China.
