Description

Male: Head. Face with distinct round facial tubercle, yellow, white pollinose, yellow pilose except black pilose laterodorsally; gena yellow; lunule yellow, yellow also between antennal bases; frons protruded forward, black with anterior M-shaped yellow macula, black pilose, golden-brownish pollinose posteriorly, shiny black medially; vertical triangle narrow, isosceles, with the ocelli on the anterior half, black, black pilose; antenna yellow, black pilose; arista dark brown, bare; eye bare, holoptic; occiput black, grey-silver pollinose, yellowish-white pilose on ventral 2/3 and brown pilose on dorsal 1/3 ( Figure 7f ).

Thorax. Scutum black, brown pollinose, yellow pilose; mesonotal fringe or collar well-defined on anterior part of scutum, with white pile; postpronotum dark, bare; notopleuron black, densely white pollinose, yellow pilose; postalar callus lighter in background colour; scutellum brownish, yellow pilose, subscutellar fringe absent ( Figure 7c, d ). Pleuron mostly dark brown to black, except posterior anepisternum yellowish on posterior half, katepisternum with dorsal yellowish macula, both areas densely white pollinose; katatergum whitish pollinose; anterior anepisternum yellow pilose on posterodorsal quarter, posterior anepisternum and meron yellow pilose, dorsal and ventral katepisternal pile patches broadly separated, metaepisternum yellow pilose ventrad to spiracle; metasternum bare; calypter yellow; plumula yellow; halter brown; posterior spiracular fringes yellow. Wing: membrane hyaline, lightly infuscated medially; stigma brown; extensively microtrichose, except costal cell bare very basally, cell R bare on basal half, cell BM bare on basal 2/3, and cell CuP and anal lobe bare basally. Alula present, broader than costal cell, bare with microtrichia on anteroapical quarter. Legs: coxae and trochanters black, pro- and mesoleg yellow, yellow pilose; metafemur yellow, metatibia black, yellow on basal 1/4, metabasitarsomere black, yellow apically, remainder of tarsi yellow.

Abdomen. Petiolate, unmargined. Dorsum mainly black, yellowish-white pilose on tergum 1, black on the remaining; tergum 1 black; tergum 2 with two basolateral yellow maculae and two more yellow maculae submedially; tergum 3 with anterior broad yellow fascia, broader than the half of tergum length; tergum 4 with anterior broad yellow fascia; tergum 5 black ( Figure 7c, d ); male genitalia black.

Female. Similar to male except normal sexual dimorphism and as follows: frons black, with anterior yellow macula, white pilose, white pollinose except a thin shiny medial line. Pleuron more yellow, lighter; scutellum yellow. Abdominal tergum 1 yellow laterally, tergum 2 with basolateral maculae and medial maculae connected laterally with yellow lateral margins, tergum 5 with two yellow maculae on anterior margin.

Variation. Female from Mt. Garnet is a bit lighter, and it seems to be a teneral specimen.

Length (N = 2). body, 11.3 mm (11 – 11.5 mm); wing, 9.8 mm (9 – 10.5 mm).

Biology

In New South Wales, Australia, a second-instar larva of Asiobaccha notofasciata was found feeding on Aphis (Aphis) clerodendri in a pseudogall of Clerodendrum tomentosum ( Blüthgen 2003; Carver et al. 2003). Blüthgen (2003) indicated that the pupal stage lasted 10 days at 23°C.

Geographical distribution

Species known from New South Wales and Queensland ( Australia).

Genetics

The BOLD Process IDs for the DNA barcodes (5 ʹ – COI) for this species are: SYRAU033-15 (specimen CNC373897), SYRAU034-15 (specimen CNC373913), SYRAU035-15 (specimen CNC373916), SYRAU036-15 (specimen CNC373910), and the following specimens: AMK379153, CNC457370, CNC451750, CNC373897, CNC373910, CNC373913, CNC373916, CNC385072, CNC451728, CNC451729 and K410200.

The GenBank accession numbers for this species are: 28S gene ( KM 270822 , specimen CNC_ JSM218 ), 18S gene ( KM 270770 , specimen CNC_ JSM218 ), protein-coding COI gene ( KM 270853 , specimen CNC_ JSM218 ).

Etymology

The specific epithet is derived from the Greek notos meaning south ( Brown 1956, p. 731) and the Latin fasciatus meaning ‘ envelop with bands, swathe ’ ( Brown 1956, p. 317), and it refers to Australia and the characteristic abdominal fasciae of this species. Species epithet is to be treated as adjective.

Differential diagnosis

This species has a mesonotal fringe, the face and the scutellum are yellow, and the alula is broader than the costal cell. Asiobaccha notofasciata has the wing bare basally, including cell R, and the abdominal tergum 4 black with a broad yellow fascia on anterior 1/2, reaching anterior margin, slightly emarginated medially on posterior margin, and tergum 5 black with two basal elongate yellow maculae on anterior margin. It can be distinguished from A. doesburgi by the abdominal colouration pattern and the contrasting, darker stigma.
