Redescription
Body length= 6.5–8.0 mm. Head. Frons wider than ocellar tubercle, profile transversely concave above antennae, pubescence as silver patches along eye margin, frontal vestiture as minute setae, texture as irregular longitudinal striations; face produced anteriorly, vestiture with dark or pale setae; gena with pale setae; parafacial glabrous; mouthparts elongate, projecting anteriorly, or sometimes relatively short; palpus brown-black, acuminate; occiput glabrous, glossy black; antennal base raised, antennal length approximately equal to head; scape black, length approximately equal to flagellum, with sparse black setae; flagellum black, base of flagellum with short dark setae. Thorax. Scutum uniform grey-black, sometimes with faint white stripes; scutellum overlain with dense, matt-black pubescence; pleuron black, overlain with sparse silver-grey pubescence; wing markings dark banded infuscate; haltere knob white; coxae black; femora brown to black; tibia black; tarsi black; fore basitarsus white distally, 2nd tarsomere basally, remaining basitarsi yellowish. Scutal chaetotaxy: np, 4; sa, 1; pa, 1; dc, 3–4; sc, 1. Abdomen. Segments 2–3 yellow, remaining segments black (male tergites 1-3 dark medially), silver velutum dorsally on tergites (male) or absent (female); terminalia dark.
Comments
The male of Acupalpa divisa has long been unknown, and herein described for the first time. Hardy (1939)[7] proposed that this species was a synonym of Acupalpa pollinosa, but has been subsequently proved incorrect as corresponding sexes of both species are now known.
