Head, collar, tegula, and thorax vermillion, antenna bipectinate in basal fourth, otherwise filiform, colour as of head. Tegula with one green rounded patch. Dorsal side of thorax with a central green patch; ventral side pale beige without markings. Legs vermillion laterally, beige medially. Abdomen uniformly pale beige, first two abdominal segments with vermillion hair scales. Fore wing short, broad, triangular,with rounded apex; ground colour vermillion, veins contrasting black in postmedial area. Medio-ventral fascia Veronese green, very broad,rounded,margined with black on distal edge.Fringe long, slightly darker than ground colour. Hind wing uniformly pale ochreous with slightly darker, long fringe. Underside of wing. Both wings pale vermillion without markings; fringe as ground colour.  Female.Fore wing length 15–16 mm. Body and wing colour as in male. Antenna filiform. Fore wing broad with outer margin more evenly arcuate than in males. Green medioventral fascia is markedly longer and slightly narrower than in males, almost parallel with outer fore wing margin; costal area with triangular green dash postmedially. Hind wing uniform pale beige; fringe somewhat darker.  Male genitalia.Uncus long, tapered, apically pointed. Tegumen broad, elongate. Gnathos broad, tapered medially with rounded apex. Juxta rounded basally, with two short, lateral, ribbon-like distal processes; manica with a bunch of long, sclerotised, curled pseudocornuti. Vinculum short and broad, rounded. Valva moderately broad at base, constricted medially, very narrow, distally forming a long, narrow, slightly curved, pointed dorso-apical process and a very short, pointed ventral process. Phallus medium-long, moderately thick, slightly medially bent with sclerotised ventral surface in its basal half. Vesica membranous without cornuti.  Female genitalia.Ovipositor short and narrow, papilla analis narrow-triangular, sparsely setose. Apophysis posterioris long, thick, straight, medially tapered, apically pointed. Eighth tergite short, quadrangular; apophysis anterioris very short. Ostium bursae relatively wide, surrounded by a heavily sclerotised, densely setose antevaginal plate. Ductus bursae short, membranous, gradually dilated anteriorly; cervix bursae largely dilated, membranous. Corpus bursae membranous, distal tubular section very short and thick; proximal part of corpus bursae ovoid with small signum bursae consisting of two fully separated, semi-circular, strongly scobinate plates.   Diagnosis The comparison between  D. meyiand  D. parvinotais provided under the diagnosis of the latter species. The new species is also reminiscent of  D. chlorodaedalabut distinguished by the somewhat larger size and slightly larger fore wing fascia with a broader base. In the male genitalia,  D. meyihas a broader and less pointed gnathos, more curved pseudocornuti of manica, markedly narrower and medially more constricted valva with a considerably longer and narrower, more pointed, less curved dorso-apical process. The phallus of the new species is much shorter, less tapering, with markedly shorter coecum than in  D. chlorodaedala. Compared to  D. parvinota,  D. meyi, is bigger in size with a larger body, and the fore wing fascia is considerably larger and broader. In the male genitalia, they are rather similar, although  D. meyihas a slimmer and apically less tapered gnathos, less curled pseudocornuti, and valva with less curved and thicker dorso- and more pointed ventro-apical processes. In the female genitalia, the antevaginal plate of  D. meyiis much smaller, smoother and somewhat more heavily sclerotised than that of  D. parvinota. The ductus bursae is similarly short in both species, but the tubular part of the corpus bursae is substantially wider in  D. meyithan in  D. parvinota. Finally, the signum bursae of  D. meyiis smaller and semi-circular in shape, compared to the larger, amorphous signum of the related species.  Genetic information This species belongs to the BIN URI: BOLD:AEO1351. As only one specimenwas sampled for DNA barcoding, no data of intraspecific variation can be provided. The nearest neighbour to  D. meyiis  D. parvinota, with 3.33% pairwise distance between the two species. The genetic divergence of  D. parvinotafrom  D. pallidifasciaand  D. chlorodaedalawas 4.15–4.30% and 6.97–7.68%, respectively.   Etymology   Delorhachis meyi is named in honour of the collector of the holotype, Wolfram Mey, former collection manager of the MfN, Berlin, renowned specialist of Microlepidopteraand Trichoptera.    Distribution and habitat( Figures 175–176, 184)   Delorhachis meyiinhabits the rainforest and secondary grassland mosaic region of Ugandaand Kenya, although the locality data suggests that this is a forest-dwelling species. 4029342444 2014-11-19 2014-11-24 2014-11-19 MfN Uganda Male Biol.
