Tropidopsilus ruber Kawai & Chemyreva 2025, comb. nov.

Tropidopsilus ruber (Buhl, 1997), comb. nov. Fig. 7A–H Material examined. Holotype of Masnerolyta ruber: “ ARGENTINA, T.d. Fuego / 34: Ushuaia / Lapataia, 20 m / 29. i. 1979 / Mission Cientifica Danesa”, “ ZMUC/ 00021917 ”, “ MASNEROLYTA / RUBER/ Peter Buhl det. 1995” (NHMD). Other labels are in Fig. 7C. Diagnosis. Distance between toruli 0.3 times as long as diameter of torulus; female antenna weakly incrassate apically with F1 as long as F2 and F3 measured together; F10–F12 as long as wide (all other antennomeres elongate) in dorsal view and about 1.5 times as wide as А1 (Fig. 7A); scutellar disc not humped, with weak posterior mesoscutellar sulcus; mesopleuron without subalar bridge, with distinct epicnemial bridge and epicnemial pit; metascutellum with short spine medially; parastigma, marginal vein and radial cell almost equal to each other (Fig. 7H); Т2 anteriorly with short three medial furrow and lateral impression (Fig. 7E, G). This species is very close to Tropidopsilus laticeps Kieffer and differs from it in the following: antennae incrassate (filiform in T. laticeps); scutellar disk moderately convex and longer than anterior scutellar pit (strongly convex and shorter than anterior scutellar pit in T. laticeps); spine on metascutellum short (long in T. laticeps); radial cell wide and long, longer than marginal vein (small and narrow, shorter than marginal vein in T. laticeps); base of T2 with short furrows (with longer furrows in T. laticeps). Distribution. Argentina (Buhl 1997). Biology. Unknown.
