description: Peromyia indecorata sp. n.
(Fig. 3 A-B)
Diagnosis:
Peromyia indecorata is characterized by the following male genitalic characters in combination: the ventral emargination extends beyond the midlength of gonocoxites (Fig. 3A), the gonostyli have a simple, subcylindrical outline (Fig. 3A), and the tegmen is largely unmodified except for the apical margin of ventral plate which is occasionally discernible (Fig. 3B).
Description (mentioned are only those features which differ from that in P. grovei):
Male. Body size: 0.9-1.1 mm.
Head: Maxillary palpus 4-segmented, first to third segments with hair-shaped translucent sensilla.
Wing: AntC ending at juncture with R5. ApicR1 = 3-4 times the length of Rs. Terminalia: Sclerotization of tg9 not interrupted mesally. Ventral emargination of gonocoxites broadly U-shaped, extending beyond midlength (Fig. 3A). Gonostylus short subcylindrical, marginally broader basally than apically, occasionally slightly curved, rounded apically (Fig. 3A). No membranous lobe between gonocoxites and tegmen. Tegmen shorter than gonocoxites, parallelsided, rounded apically; ventral plate indistinct, its apical margin sometimes traceable just below tegmen apex (Fig. 3B). Both cerci and st10 large; cerci setose.
Female and preimaginal stages: Unknown.
Remark on variation:
There is some individual variation in the extent (depth) of the ventral emargination of gonocoxites. Some gonostyli are thicker than the one depicted (Fig. 3A) and occasionally are slightly curved.
Etymology:
From the Latin, meaning in a figurative sense inconspicuous.
