description: Toropsis minuspina sp. nov.
(Figs. 7–12, 26–33)
Description. Length. ♂ 3.4 mm, ♀ 4.2–4.6 mm.
Body pale stramineous. Crown brown. Pronotum with irregular mottled brown or black band across anterior margin. Mesonotum and scutellum yellowish brown, with basal triangles ocher (Fig. 7). Forewing hyaline, mottled with light brown, veins slightly darker than membrane (Fig. 8). Face infused with yellow, punctuation little or no darker than surrounding areas. Ocellar and eyes red brown (Fig. 9).
Body wedge shaped. Head wider than pronotum, face across eyes narrower than long, dorsal margin rounded in male, somewhat angulate in female; frontoclypeus small and flat; ocelli slightly closer to adjacent eyes than to each other; coronal pits poorly developed, slightly farther apart than ocelli; lora clearly defined in both males and females; anteclypeus small and flat, expanded apically in males (Fig. 9). Crown covered by pronotum medially in dorsal view. Pronotum inflated, vertical anteriorly, striae transverse posteriorly, oblique anteriorly, anterior margin in lateral view even with or slightly surpassing dorsal margin of head. Medonotum and scutelllum triangular, marked with lines and dots (Fig. 7). Tegmen length greater than 2.5 times width, 3 preapical cells, extra crossveins present in some specimens (Fig. 11). Hind tibial chaetotaxy PD 11, AD 7, AV 5 (Fig. 8).
Male genitalia. Pygofer broad, apex of ventral margin with several small papilliform processes. Subgenital plates of typical shape, with numerous irregularly arranged fine setae (Figs. 26, 27). Aedeagus with preatrium weakly developed; shaft tubular, slender, evenly curved in lateral view with apex tapered; in posterior view with atrium pear-shaped, shaft tapered with small, widely spaced lateral spines; gonopore subapical (Figs. 28, 29). Dorsal connective small, sinuate in lateral view, foot-shaped dorsoapically (Fig. 31). Style slender, angled on basal 1/3, distal part slightly sinuate, nearly parallel-sided, with slightly reflexed tips (Fig. 30). Connective small, anterior margin slightly concave, median anterior lobe well developed between dorsally bent anterolateral arms (Figs. 32, 33).
Female. Body coloration and appearance similar to males, paler overall (Figs. 10, 11).
Material examined. Holotype: ♂, Australia: Queensland, Noonbah Station, first light trapping site light, 12 Feb 2008, Coll. K. Hill, D. Marshall, C. Owen, M. Moulds and M. Humphrey (QM); Paratypes: 2♀♀, same data as holotype (INHS).
Distribution. Australia.
Remarks. The new species can be distinguished by the unique apex of pygofer and weakly thorned aedeagus shaft.
Etymology. The new species name, a noun in apposition, is a combination of the latin words “ minuta ” and “ spina ”, referring to the tiny spinous rim of the aedeagus in ventral view.
