Type material. HOLOTYPE: Western Australia: Applecross , 10.vi.1934, K.R. Norris, emerged from rotting wood 18.vii.1934 (1♂, ANIC).

Redescription

Male. Body length 3.0– 3.8 mm. Anepisternal disc present. First flagellomere orbicular. Bristles black. Arista closely pubescent. Vibrissa curved and relatively short (although not as short as vibrissa of H. laticornis ). Ocellar bristle long. Two dorsocentral bristles (broken) with slightly more well developed setula in front of anterior dorsocentral. Occiput relatively large, and gena high and gradually curved medially. Face and buccal cavity evenly curving and velvety. Frons dark brown with anterior margin, posterior margin and faded spot in front of anterior ocellus brownish-orange; occiput and posterior half of gena brown; antenna (excluding arista) orange-yellow with anterodorsal margin and distal 1 ⁄ 3 of first flagellomere infuscated; distal 2 ⁄ 3 of palpus brown, (excluding inner margin); parafacial and dorsal half of gena silvery tomentose, frons broadly pilose anteriorly. Thorax dark brown. Fore legs dark brown with base of tibia yellow and fore coxa dirty yellow/light brown and silvery tomentose with base brown; mid tibia, coxa and femur dark brown with base and apex of femur yellow; mid tarsi yellow; hind coxa brown (remainder of hind legs missing—D.K. McAlpine [1960] describes those parts as dark brown with knee and middle of tarsi yellowish). Fore tarsi ovate in cross section. Abdomen dark brown. M 1+2 ratio approximately 5.5. Wing only clouded along R 2+3 and R 4+5 on distal 1 ⁄ 3. Halter white with stalk brownish (darker to base).

Female. Not examined.

Male terminalia ( Fig. 64 View Figures 62–68 ). Epandrium largely obscured, but width, height and length appearing subequal. Cerci approximately half height of epandrium, narrowing distally and with small apical emargination. Surstylus long and triangular (strongly tapered on distal half) with several distal tubercle-like bristles.

Comments. Heteromeringia norrisi is one of only two Heteromeringia known from Western Australia. The other is the relatively widespread H. trisetosa , which also occurs in New South Wales, Queensland and Tasmania, and is characterized by three pairs of dorsocentral bristles.

One of the paratype females (not examined) was collected in a log with termites (D.K. McAlpine, 1960).
