( Fig. 1 A-C) Diagnosis: Peromyia groveigrovei is characterized by a combination of male genitalic characters as follows. The ventral emargination extends to the midlength of gonocoxites ( Fig. 1B ), the gonostyli are flattened and excavated mesally ( Fig. 1B ), and the tegmen has dark lateral stripes ( Fig. 1C ). Description: Male. Body size: 0.7-0.8 mm . Head: Postfrons asetose. Eye bridge 2-3 ommatidia long. Postocular bristles in 2 rows. Neck of fourth antennal flagellomere longer than node ( Fig. 1A ). Node subglobular, with 1 basal whorl of short hair-shaped sensilla, short subbasal setae, 1 mesal single to triple whorl of long setae and 1 distal whorl of long hair-shaped sensilla. Maxillary palpus 4-segmented, all segments with hair-shaped translucent sensilla. Fig. 1: Peromyia grovei sp. n. , holotype male. – A: fourth antennal flagellomere, lateral view; - B: terminalia, ventral view; - C: tegmen, ventral view. Length of scale bar = 0.05 mm. Wing: AntC ending at juncture with R5 or extending slightly beyond R5. ApicR1 = 3 times the length of Rs. Legs: Pretarsal claws without teeth. Terminalia: Sclerotization of tg9 mesally interrupted for a short distance. Ventral emargination of gonocoxites broadly U-shaped, extending to midlength ( Fig. 1B ). Gonostylus flattened, excavated dorsomesally, rounded apically ( Fig. 1B ). In between gonocoxites and tegmen a weak membranous pubescent lobe. Tegmen as long as gonocoxites, tapering towards apex, apically rounded, with dark lateral stripes approaching each other near apex; apical margin of ventral plate situated just below tegmen apex ( Fig. 1C ). Both cerci and st10 distinct, pubescent; cerci bearing a few fine setae. Female and immature stages. Unknown. Etymology: The species is named to honour Dr Simon J.
