Peromyia despecta sp. n.

(Fig. 6 A-C)

Diagnosis:

Peromyia despecta is a typical represetative of the Peromyia modesta (FELT) group as defined by JASCHHOF (1998) and reviewed subsequently ( JASCHHOF 2001b, JASCHHOF & JASCHHOF 2004, 2009). It is very similar to a number of species occurring in the Holarctic Region including Japan,

in particular Peromyia boreophila JASCHHOF, 2001 . The following characters in combination are species-specific for P. despecta: postocular bristles are present in 2 rows; the whorl of short hair-like sensilla on the antennal flagellomeres is situated mesally, just beyond the double whorl of setae (Fig. 6A); the gonostyli are elongate and slightly curved (Fig. 6B); and the ventral plate of the tegmen is weak and comparatively long (Fig. 6C).

Description:

Male. Body size: 0.8-0.9 mm.

Head: Postfrons asetose. Eye bridge 2-4 ommatidia long. Postocular bristles in 2 rows. Neck of fourth antennal flagellomere as long as node (Fig. 6A). Node subglobular, with short subbasal setae, 1 mesal double whorl of long setae, 1 mesal whorl of short hair-shaped sensilla, and 1 irregular distal whorl of long hair-shaped sensilla. Maxillary palpus 3-4-segmented, all segments with hair-shaped translucent sensilla.

Wing: AntC ending at juncture with R5 or extending beyond R5 for once the vein width. ApicR1 = 3.5-4.0 times the length of Rs. Legs: Pretarsal claws without teeth.

Terminalia: Sclerotization of tg9 interrupted mesally. Ventral emargination of gonocoxites broadly U-shaped, extending to midlength (Fig. 6B). Gonostylus large, comparatively long, slightly curved inwards, slightly tapering towards apex (Fig. 6B). Tegmen shorter than gonocoxites, slightly tapering towards apex, rounded apically; ventral plate weak, covering 2/3 of tegmen length, its apical and basal margins often barely traceable (Fig. 6C). Both cerci and st10 well developed, pubescent; cerci with a few fine setae.

Female and preimaginal stages: Unknown.

Etymology:

From the Latin, meaning unnoticed.
