Key to the species of Goniglossum

1. Thorax more extensively yellow ( Figs. 5 , 7 ): Scutum medially (on approximately medial 0.33) with black pattern restricted to posterior half or less; scutellum medially with 3 black spots: 1 larger, rectangular or triangular, dorsomedial spot, and 2 smaller ventroapical spots partly united on ventral surface of scutellum, and sometimes (in about 50% of the specimens) also partly united with dorsal spot, although narrow but distinct yellow gap between these 3 black spots always present at tip of scutellum; pleuron paler, without extensive contrasted dark areas, at most with small rounded dark (usually brown to black) spot posterodorsally on katepisternum and similar spot on meron ( Figs. 7 , 16 ); small blackish spots also present on posterior part of anatergite and katatergite, and large triangular spot (or otherwise blackish area) sometimes present on katepisternum. Abdomen yellow to brown, without black bands; tergites 2–4 in male, 2–5 in female with golden-yellow microtrichia either completely covering tergites or only their posterior margins; only last tergite bare and shiny. Aculeus: with narrower apex ( Fig. 14 a); aculeus-width-ratio averages 3.90 (range: 3.50–4.23); serration of arrow-head apex less extensive, averaging 7.2 teeth (range: 5–8; Fig. 14 b). Glans: bubble-like structure about as long as sclerotized part between “bubble” and distal margin of sclerotized part ( Fig. 12 )............................................................... G. wiedemanni Meigen

-. Thorax more extensively black ( Figs. 3, 4 , 6 ): mesonotum medially usually with black pattern both anteriorly and posteriorly, except narrow yellow areas such as on and near postpronotal lobe and on transverse suture; apex of scutellum with single large quadrangular black spot rarely interrupted by small yellow spot centrally; pleuron darker, with extensive dark areas: with 2 more or less complete dark (often black) longitudinal vittae strongly contrasted with narrow whitish dorsal stripes, best seen on anepisternum and katepisternum ( Figs. 6 , 16 ). Abdomen varies from mostly yellow to mostly black, usually with pairs of black bands, one pair on each tergite, pair members sometimes united, forming more or less complete transverse bands; abdomen entirely shiny or subshiny, without obvious microtrichia. Aculeus: with wider apex ( Fig. 13 a): aculeus-width-ratio averages 2.14 (range: 1.91–2.37); serration of arrow-head apex more extensive, averaging 13.3 teeth (range: 11–15; Fig. 13 b). Glans: bubble-like structure of glans distinctly longer, about 1.5 times as long as sclerotized part between “bubble” and distal margin of sclerotized part ( Fig. 11 )..................................................................... G. liat n. sp.
