( Figures 1G–H View Figure 1 , 4A–G View Figure 4 )

Description

Small, oval species, length (from apex of vertex to tip of forewings): male (n = 3), 4.5–4.8 mm.

General colour stramineous brown, frons pale yellowish with base black, clypeus pale yellowish, antennal sockets, scape and pedicel black; rostrum with apical segment brown; thorax beneath brownish; legs and claws dark brown, hind coxae and trochanters pale yellowish, hind tibiae and tarsi pale brown, tips of spines on hind tibiae and tarsi black; forewings ( Figure 1G,H View Figure 1 ) fuscous, the apical marginal area blackish, with the following areas or fasciae whitish: the extreme basal costal area, an oblique fascia running from middle costal margin to clavus beyond apex of scutellum, a subtriangular marking on the subapical costal and subcostal area (the veins within the marking brown) and an indistinct, narrow, oblique fascia running from the inner basal edge of this whitish subapical costal and subcostal marking to the claval apex; the apex of clavus and the subapical corium whitish; hindwings hyaline, covered with brown hairs, veins brown; abdomen black with segmental margins white.

External structure as in the generic description. Head ( Figures 1G View Figure 1 , 4A View Figure 4 ) maximum width (including eyes) 3.3–3.4 times as long as median length. Vertex ( Figures 1G View Figure 1 , 4A View Figure 4 ) without median carina, median length 0.5–0.6 times as long as length of pronotum medially. Frons ( Figures 1H View Figure 1 , 4B View Figure 4 ) in the males moderately bulbous, not strongly compressed laterally, median longitudinal carina indistinct. Pronotum ( Figures 1G View Figure 1 , 4A View Figure 4 ) without median longitudinal carina, median length 0.5–0.6 times as long as maximum width.

Male genitalia with pygofer ( Figure 4C View Figure 4 ) high, slightly narrow, width ventrally nearly as wide as dorsally, subquadrate in lateral view, anterior margin sinuate, dorsal posterior margin angularly produced in lateral view. Basal anal processes ( Figure 4C,E View Figure 4 ) relatively short, directed posterodorsally in lateral view, inner edge covered with fine spines on apical half. Subgenital plates ( Figure 4C,D View Figure 4 ) short, apically bilobed, both plates widely separated from each other. Genital styles ( Figure 4C,D,F,G View Figure 4 ) relatively short, narrow and slender, evenly tapered sub-basally to apex, apically bidentate. Aedeagal shaft ( Figure 4C,G View Figure 4 ) short and stout, slightly arched anteriorly in lateral view, anterior edge covered with many tiny spines in lateral view; gonopore apical.

Material examined

Holotype. male, [ Australia] 5 km east of Stanley , Tas., 15 November 1975, K.R. Norris ( ANIC).

Paratypes. [ Australia:] two males, same data as holotype ( ANIC) .

Etymology

This new species is named for its general appearance being similar to A. tiegsi ( China, 1952) .

Distribution

Australia (Tasmania).

Remarks

This is the smallest species currently known in Anyllis . This species can be distinguished from other known species in the genus by its small body size and distinctly oval body form ( Figure 1G,H View Figure 1 ), vertex and pronotum without median carina ( Figures 1G View Figure 1 , 4A View Figure 4 ), frons with indistinct median carina ( Figure 4B View Figure 4 ) and the male genitalic structure ( Figure 4C–G View Figure 4 ). In external appearance, this species is similar to A. tiegsi ( China, 1952) , but differs from the latter in the smaller body; vertex ( Figure 4B View Figure 4 ) without median carina, median longitudinal carina on pronotum ( Figure 4A View Figure 4 ) completely obsolete, and the pygofer with the basal anal process directed posterodorsally, with inner edge covered with fine spines only on apical half ( Figure 4C,E View Figure 4 ).
