Diagnosis.

Black postocular setae scattered over occiput in both sexes; flagellum shorter than scape; scutum dark; wing infuscation as two bands, apex with white infuscation; costal cell hyaline except for brown infuscation distally; legs dark with white on dorsal surface of tibia; male abdomen lacking silver pubescence.

Description.

Length 10.0-12.5 mm. Head. Glossy black, smooth. Frons slightly verrucous, raised around base of antennae. Eyes separated by 4 × width of median ocellus in both sexes. Parafacial silver pubescent, face glabrous medially. Occiput sparse silver pubescent, denser laterally and ventrally onto gena, admixed with scattered, black setae; posterior oral margin black, sparsely pubescent. Postocular macrosetae black scattered on occiput, not in distinct rows. Scape 1.3 × head length, brown basally, black on apical 3/4, sparsely pubescent. Pedicel black, 1/10 × length of scape, densely covered with short, black setae. Basal flagellomere ½× length of scape, short, black setae covering entire length. Second flagellomere subequal in length to third flagellomere, extremely short. Style minute. Palpus cylindrical basally, apex spatulate with a truncate tip; cream-coloured basally and medially towards apex, otherwise black. Mouthparts black except labellum, which is grey-brown; brown setose. Thorax. Dark brown. Matte black anteromedially on scutum. Silver pubescence on dorsal part of proepimeron, posterior katepisternum, lateral and extreme posterior part of scutum, scutellum, posterior anepimeron, metanepisternum, metepimeron, meron, and metakatepisternum; macrosetae black (np: 2, sa: 1, pa: 1, dc: 0, sc: 1); notum and katatergite with short, white setae. Legs. Black except white on dorsal surface of tibiae and basal 3/4 of mid- and hind basal tarsomere; sparsely silver pubescent, admixed with short, black setae. Fore- and midcoxa with four black anteroventral, marginal macrosetae. Hind coxa with anteroventral margin truncated with a single black, anteroventral, marginal macroseta. Wing. Strongly banded, dark areas infuscated with dark microtrichia; broad subapical band and a narrow band at mid length; apex with white infuscation; hyaline areas mostly lacking microtrichia. Pterostigma brown. Venation brown except anterior costal margin, basal Sc, and all veins at wing apex cream-coloured; cell m3 widely open at wing margin. Haltere stalk brownish, knob white. Abdomen. Segments mostly black, white laterally on tergite I and with a broad white band on segment II; shiny, lacking pubescence, sparsely covered with short, black setae; tergites I and II with long, white setae laterally. Genitalia. Male: tergite VIII with anterior margin slightly emarginated. Sternite VIII quadrate, wider posteriorly. Epandrium dark, quadrangular with posterolateral processes. Cercus broad, rounded posteriorly. Subepandrial sclerite wide, 2/3 width of epandrium; partially sclerotised, lateral margins more strongly so. Gonocoxites dark brown with dark, elongate, setae laterally, inner gonocoxal process curved medially along length, rounded apically; outer gonocoxal process angular. Aedeagus with dorsal apodeme of parameral sheath ‘T’ -shaped, laterally forked apically; ventral apodeme divergently forked, arms broad; distiphallus robust, straight with numerous sinuous processes apically. Ejaculatory apodeme robust, roughly cylindrical, with a dorsal carina and anterior end with a blunt cap; lateral ejaculatory apodemes arc-like around basiphallus. Female: tergite VIII wider than long, narrower posteriorly, with a narrow anteromedial projection. Acanthophorite and acanthophorite spines dark brown. Sternite X triangular, anterior margin truncate. Spermathecal duct equal to 4 × length of furca. Spermathecal sac duct equal to 3.5 furcal lengths; sac ovoid, longer than wide; 0.5 × length of spermathecal sac duct.

Etymology.

The species epithet is derived from the Latin grandis, great, large, magnificent, and - osus, fullness, abundance; referring to the distinctive size and striking wing patterning of this species. Gender is masculine.

Comments.

Calophytus grandiosus sp. nov. is a relatively large species with distinctive wing banding and black and white legs. It is distinct from other Calophytus species and is rather isolated in the genus as sister to the rest of the genus (Fig. 4 View Figure 4 ). This species is found in the mid- to upper-elevation forests (Figs 31 View Figure 31 , 32 View Figure 32 ). GenBank sequences for this species (see Winterton et al. 2016: table S1): KT290078 (16S rDNA), KM885004 (28S rDNA), KM879121 (EF1a).
