Diagnosis.

Frons profile concave above antenna; antenna black; wing dark banded; legs black with basitarsus and second tarsomere white; abdomen black, overlain with silver velutum in male.

Redescription.

Body length= 6.9-9.3 mm. Head. Frons wider than ocellar tubercle, profile transversely concave above antennae, pubescence as two silver patches along eye margin, vestiture as minute setae; frons surface texture as irregular longitudinal striations; face projecting anteriorly, vestiture with dark to pale setae; gena with pale setae; parafacial glabrous; mouthparts relatively short (approximately equal to head length); palpus brown-black, acuminate; occiput glabrous, glossy black; antennal base raised; antennal length approximately equal to head; scape brown to black, length much shorter than flagellum, with sparse black setae ventrally; flagellum black, base of flagellum with short, dark setae. Thorax. Scutum uniform grey-black; scutellum overlain with dense, matt-black pubescence; pleuron black, overlain with sparse silver-grey pubescence; wing markings dark banded infuscate; haltere knob white, stem dark brown; coxae and femora brown to black; tibia dark; tarsi dark, basal ¾ of fore-basitarsus and entire second tarsomere cream to white. Scutal chaetotaxy (macrosetae pairs): np (notopleural), 4; sa (supra-alar), 1; pa (post-alar), 1; dc (dorsocentral), 2-3; sc (scutellar), 1. Abdomen. Black, covered with silver velutum dorsally on tergites (male only); terminalia pale.

Comments.

Ectinorhynchus albimanis is herein transferred to Acupalpa with Acupalpa pollinosa becoming a junior synonym of Acupalpa albimanis comb. n. Mann (1928) redescribed Ectinorhynchus albimanis based on a series of specimens, but clearly did not examine the type, as his redescription does not match that in Kröber (1914) nor reflect characteristics of the type. Acupalpa albimanis is morphological similar to Acupalpa albitarsa and Acupalpa yanchep sp. n. The colouration of abdomen and tarsi is diagnostic for this species.
