TABLE 2. Grouping of the Nososticta salomonis complex based on morphological characters and distribution.
NameDiagnostic characters considered most usefulKnown distributionN. salomonis (holotype)M: ahp not markedly more or less than 1/2 the length of mesanepisternum; black area between ahp without long narrow basal stalk; mep yellowish to greyish brown, as long as metepimeron, dorsal half of its anterior margin almost straight; poststernum yellow; S2 without distinct blue dorsal marking.Solomon Is: probably UgiN. salomonisM: ahp not markedly more or less than 1/2 the length of mesanepisternum; black area between ahp without long narrow basal stalk; mep partly pale yellowish to greyish brown, as long as metepimeron, dorsal half of its anterior margin almost straight; poststernum largely yellow to pale bluish or greyish brown, indistinctly patched with brown; S2 without distinct blue dorsal marking. F not available.Solomon Is: San Cristobal: MakiraN. salomonisM: ahp not markedly more or less than 1/2 the length of mesanepisternum; black area between ahp without long narrow basal stalk; mep markedly shorter than metepimeron, dorsal half of its anterior margin almost straight; poststernum completely or almost completely black; S2 without distinct blue dorsal marking. F: ahp short, parallel sided and narrow in cases even missing; blue patch on S 8.Solomon Is: Choiseul, Ranongga, Vella LavellaN. salomonisM: as from Choiseul, Ranongga, Vella Lavella. F not available.Solomon Is: Santa IsabelN. salomonisM: ahp not markedly more or less than 1/2 the length of mesanepisternum; black area between ahp without long narrow basal stalk; mep not distinctly or only somewhat shortened, dorsal half of its anterior margin almost straight; poststernum largely pale bluish or pale greyish yellow with rather distinct small and narrow greyish to brownish black patches. S2 without distinct blue dorsal marking. F not available.Solomon Is: Kolambangara, New Georgia, RendovaN. salomonisM: ahp not markedly more or less than 1/2 the length of mesanepisternum; black area between ahp without narrow basal stalk; mep shorter than metepimeron, dorsal half of its anterior margin almost straight; poststernum pale blue, patched with dark grey to black, to almost black; S2 without distinct blue dorsal marking. F: ahp short, generally almost parallel sided, poststernum markedly paler than in male; blue patch on S 8.Solomon Is: MalaitaN. salomonisM: ahp markedly more than 1/2 the length of mesanepisternum; black area between ahp without narrow basal stalk; mep as long as, or (rather rarely) shorter than, metepimeron, dorsal half of its anterior margin almost straight; poststernum largely bluish to pale greyish yellow with dark brown to black patches; S2 without distinct blue dorsal marking. F: ante-humeral patch parallel sided, narrow, at least 1/2 the length of mesanepisternum; blue patch on S 8 absent or present.Solomon Is: Guadalcanal
