Peromyia cinalata sp. n.

(Fig. 8 A-C)

Diagnosis:

Peromyia cinalatacinalata is tentatively assigned to the modestamodesta group, because of the presence of two whorls of hair-shaped sensilla on the antennal flagellomeres (Fig. 8A), large gonocoxites and thick, subcylindrical gonostyli (Fig. 8B). The whorl of short sensilla is irregular and situated subbasally on the flagellomere nodes (Fig. 8A), which is unusual among the species of the modesta group (but see above Peromyia debilis, Fig. 7A). The slender tegmen with weak ventral plate in P. cinalatacinalata is also atypical of this group and more often found among species of the Peromyia san-

guinea (KIEFFER)) group (cf. JASCHHOF 1998). Grey-tinged wings is another unusual character of P. cinalata and to my knowledge unknown in any other Peromyia .

Description:

Male. Body size: 1.0 mm.

Head: Postfrons asetose. Eye bridge 2-3 ommatidia long. Postocular bristles in 1 irregular row. Neck of fourth antennal flagellomere longer than node (Fig. 8A). Node subglobular, with short subbasal setae intermingled with 1 irregular whorl of short hair-shaped sensilla, 1 mesal double whorl of long setae, and 1 irregular distal whorl of long hair-shaped sensilla. Maxillary palpus 3- 4-segmented, first and second segments with hair-shaped translucent sensilla.

Wing: AntC ending at juncture with R5. ApicR1 = 2.5-3.0 times the length of Rs. Wing membrane with grey tinge, possibly resulting from unusually dense, thick microtrichia. Legs: Pretarsal claws without teeth.

Terminalia: Sclerotization of tg9 not interrupted mesally. Gonocoxites long, with poorly sclerotized, asetose basal portion, ventral emargination broadly U-shaped, not extending to midlength (Fig. 8B). Gonostylus large, thick, subcylindrical (Fig. 8B). Tegmen slender, elongate, slightly tapering towards apex, rounded apically; ventral plate weak, subtriangular, with indistinct basal and distinct apical margins (Fig. 8C). Cerci large, setose. St10 weak, apparently one-lobed, sparsely pubescent.

Female and preimaginal stages: Unknown.

Etymology:

The name is Latin, composed of cinis, ash, and alatus, winged, and refers to the grey-tinged wings of this species.
