Peromyia nitoda sp. n.

( Fig. 2 A-B)

Diagnosis:

Peromyia nitoda is characterized by the following male genitalic characters in combination: the ventral emargination extends to the midlength of gonocoxites ( Fig. 2A ), the gonostyli are thick throughout their lengths and slightly curved ( Fig. 2A ), and the tegmen has dark mesal stripes ( Fig. 2B ).

Description (mentioned are only those features which differ from that in P. grovei ):

Male. Head: Maxillary palpus 4-segmented, first to third segments with hair-shaped translucent sensilla.

Wing: AntC ending at juncture with R5. ApicR1 = 2.5-3.0 times the length of Rs.

Terminalia: Sclerotization of tg9 not interrupted mesally. Ventral emargination of gonocoxites broadly U-shaped, extending to midlength ( Fig. 2A ). Gonostylus thick, slightly curved, broadly rounded apically ( Fig. 2A ). Membranous lobe between gonocoxites and tegmen distinct. Tegmen shorter than gonocoxites, slightly tapering towards apex, rounded apically, with dark mesal stripes;

apical margin of ventral plate situated just below tegmen apex ( Fig. 2B ). Both cerci and st10 large; cerci asetose.

Female and preimaginal stages: Unknown.

Etymology:

The species name is made up of the first two letters each of the forenames of Niklas JÖNSSON, ToT bias MALM and Dawn awna WILLIAMS, all of Naturhistoriska Riksmuseet Stockholm, Sweden, who are the collectors of a part of the peromyias studied here .
