Description.

Body length: 6.5 mm. Head. Frons flat, rugose-striated medially, wider than ocellar tubercle at narrowest point, antennal base positioned low on frons; lower frons and face protruding only slightly with curved ridge above antennal base; frons glossy black, short setae sparsely distributed on upper frons, silver-grey pubescence on parafacial, oral cavity and along eye margin; ocellar tubercle flat, black; occiput concave, black, overlain with grey pubescence; few relatively strong short black postocular setae followed by weaker setae in several irregular rows; elongate black setae along lower postocular admixed with white setae along gena; gena black, overlain with silver-grey pubescence; palpus and labellum brown-black with sparse, dark setae; antenna two-thirds length of head; scape and pedicel black with short dark setae; scape about half length of flagellum, cylindrical, with grey pubescence; flagellum with red-brownish suffusion and grey pubescence. Thorax. Glossy black; scutum and scutellum overlain with grey-black pubescence admixed with relatively short, dark setae; scutum with pair of narrow dorsocentral stripes of sparse pale-grey pubescence bordering a darker medial stripe; scutal macrosetae black; pleuron and sternum glossy black; broad stripe of silver pubescence along pleuron from proepisternum to hind coxa; fore and middle coxae dark brown, hind coxa black; posterior surface of hind coxa with silver pubescence; elongate pale setae on proepisternum and coxae, black setae on katatergite; fore and middle femora dark brown, hind femur black; elongate yellowish-grey velutum patches to ventral surface of hind and apical half of fore femora; pale setae of various lengths on all femora; tibiae black to dark brown; mid and hind basitarsi dark yellow basally; wing dark infuscate, venation and stigma dark grey; haltere matte brown; scutal chaetotaxy (pairs): notopleural, 4; supra alar, 1; post alar, 1; dorsocentral, 4; scutellar, 1. Abdomen. Glossy black with short dark setae distributed evenly; erect whitish setae laterally on segments 1 and 2; segments 7 and 8 orange in colour with sparse, erect black setae. Female genitalia. Three spermathecae and a relatively small, simple spermathecal sac.

Etymology.

The species epithet is derived from Latin, mico shine; ora border; reference to the silver-grey pubescence border of the eye.

Comments.

Vomerina micora sp. n. is more slender in body than Vomerina humbug and Vomerina comapenis sp. n. and can be distinguished by the dorsocentral stripes on the scutum, short, cylindrical scape, and the pleural stripe not extending onto the abdomen. The orange terminal abdominal segments may prove to be a sexually dimorphic character, as is found in many other therevid species. The male is unknown.
