Abstract: Wilkinsonellus amplus Austin & Dangerfield, 1992 Fig. 2 Wilkinsonellus amplus Austin & Dangerfield, 1992: 62. Holotype in ANIC (not examined but original description checked). Wilkinsonellus amplus: Long and van Achterberg 2011: 125; Arias-Penna et al. 2014: 32; Fernández-Triana et al. 2020: 995. Material examined. • 1 ♀; Solomon Islands, Guadalcanal Island, Honiara; 13–16. ix. 1953; J. D. Bradley, Rennell I. Expedition, B. M. 1954–222, M [ercury]. V [apour]; light; NHMUK 101639756. Diagnosis. Similar to W. tomus except the following: body much larger, ♀ length 3.9–4.1 mm, ♂ length 3.5–3.9 mm; area between ocelli black (Fig. 2 d); sometimes patch on posterior tergites and apex of metafemur, tibia and metatarsus dark brown to black; eyes very large, inner margins of eyes at antennal sockets deeply emarginate (Fig. 2 c); face narrow, head across medial face 2.5 × as wide as face (Fig. 2 c); ocelli large, closer to each other than their own diameter, lateral ocelli raised above vertex on a low turret, separated from eye margin by 0.5 × their own diameter (Fig. 2 d); temple and occiput narrow; medial part of posterior band of scutellum rugose (based on Austin and Dangerfield 1992). Distribution. Australia, Solomon Islands (new record). Note. This species is easily distinguished from its congeners by its large size, large eyes, large and strongly protuberant ocelli, yellow mesosoma, deeply emarginated inner eye margins and more transverse head (Austin and Dangerfield 1992; Long and van Achterberg 2011). The specimen from the Solomon Islands is consistent with the descriptions and illustrations in the above references except for the larger body size (4.9 mm in length).
