Fig. 10A–B

Diagnosis. Peromyia sororia is known from a single male that differs from P. leveillei , an extremely similar species redescribed above, in the following characters. The new Peromyia is larger, with a body length of 1.6 mm; the eye bridge is somewhat longer, namely 5 ommatidia long dorsally; the short palpus is 3-segmented, all segments the same length and bearing hair-shaped translucent sensilla; the medial whorl of translucent sensilla on the flagellomeres is situated distally of, not intermingled with, the basal setae ( Fig. 10B ); wing veins are of normal strength, not unusually weak; and the gonostylus is slightly longer and less bent ( Fig. 10A ).

Etymology. The species epithet, sororia , is the Latin adjective for sororal, in reference to the similarity with Peromyia leveillei .

Holotype. Male, Japan, Honshu, prefecture Iwate, Tamayama , Koma , in secondary deciduous forest predominated by oak, 15 June–4 July 1999, T. Gotoh (in KUEC).
