Material examined

Holotype: ♂ / pictipennis Lea type Kuranda/ Oomela pictipennis Lea Queensland type I.17119/ Paropsimorpha pictipennis Daccordi / ( SAM). The holotype is damaged; it has been dissected and remounted by a previous borrower (basal half of penis missing), with some parts mounted in euparal.

Description

Adult male. Length: 3.7–4.5mm. Colour ( Figs. 1–2 View FIGURES 1–3 , 28 View FIGURES 27–32 ): dorsum variegated in shades of brown and pale straw yellow, often with slight metallic reflections; head darker at base than apex, appendages yellow except antennomeres 3–5 mostly brown, 6–11 blackishbrown with slight bluish reflection; pronotum brown, paler laterally and anteriorly; scutellum yellow; elytra pale yellow (reddish­yellow and less clearly marked in old specimens) with irregular brown to blackish­brown markings: along middle of base, at margins below humeri, from basal third of suture sinuously towards apex of outer margin, along apical third of suture; these markings sometimes fused or apical sutural marking reduced to spots; venter and legs yellowish­brown, lateral thoracic sclerites sometimes darkened. Pubescence: dorsum glabrous except setae at antero­lateral corners of labrum and clypeus, small trichobothrial setae at pronotal corners; venter with scattered setae on prosternal process, metaventrite and abdomen. Microsculpture: dorsum and venter shining, without microsculpture.

Head ( Figs. 3–4 View FIGURES 1–3 View FIGURES 4–9 ): clypeus distinctly punctured, at least along frontoclypeal suture; frons and vertex impunctate except at base of head capsule; eyes separated by about 3x eye lengths; all antennomeres elongate, 2 equals 6 shortest, 11 longest, 3–6 narrower than 2 (6 narrowest).

Thorax ( Figs. 1–2 View FIGURES 1–3 , 5–7 View FIGURES 4–9 ): surface of pronotum with sparse large punctures, denser at middle and 2–7 larger elongate punctures on either side of basal edge; prosternal process elongate, ridges convergent anteriorly at anterior prosternal margin; elytral striae evanescent in apical third and at base, except first and deeply grooved base of 5th, interstrial punctures minute or absent; humeri pronounced, with slight posthumeral depression on 9th stria; hind tarsomere 5 longer than 1.

Abdomen ( Figs. 8 View FIGURES 4–9 , 10 View FIGURES 10–14 ): apical margin last ventrite slightly convex, shallowly depressed at middle.

Male genitalia ( Fig. 10 View FIGURES 10–14 ): penis dorsally longitudinally grooved, basal foramen more than half length of penis; everted endophallus with two apical hooks and without flagellum.

Adult female ( Figs. 9 View FIGURES 4–9 , 11–14 View FIGURES 10–14 ) as male except: length 4.3–5.3mm; first tarsomere more elongate, without ovate patch of spatulate setae, apex last ventrite more strongly convex, not depressed ( Fig. 14 View FIGURES 10–14 ); tergite VIII with concave apex; vaginal palpi flat; spermatheca with heavily sclerotised U­shaped base and densely convoluted duct.

Distribution

Alfius pictipennis occurs from the southern end of the Atherton Tableland to the Windsor Tableland, in northern Queensland.

Biology

Host­plants are unknown but the species is associated with rainforest. All detailed localities are elevated, at 680–1150m. The adults have been collected most of the year (November to March and a singleton collected within the period June to August) but are rare. All recent material examined for this study was collected in flight intercept traps.

Notes

Specimens from Windsor Tableland have slightly more sparsely and weakly punctured pronota and more extensive dark areas on the elytra and venter, but are not distinguishable on genitalic characters.
