Diagnosis and comments. This species looks much like S. hermetica in structure and color pattern, but differs in having a coarser macropunctation on clypeus, head and mesosoma; a larger apical propodeal lamella obtusely dislocated marginally from the valvula; a broader and dorsally more convex T1 with the transverse carina hardly reaching the level of the spiracle, and the more plainly black general color, due to a shorter, sparser and lighter pilosity.

Description. FEMALE. Differing from S. hermetica in: Measurements and proportions. Wing length 11.7 mm. Clypeus 1.13 × as wide as high and with its apical margin 0.89 × as wide as the interantennal distance. S1 2.24 × wider than its medial length and 1.56 × longer than its total length. S1 2.24 × longer than its medial length and 1.56 × longer than its total length.

Structure. Apical clypeal teeth broader. Humeral angle less produced. Pronotal sides more convex in dorsal view. Propodeal declivity slightly depressed along the medial line. Apical propodeal lamella longer, obliquely pointing upward, separated from the valvula by a slight lateral crease and a very obtuse marginal dislocation. T1 diverging more abruptly behind, with hardly salient spiracular tubercles, with a convex anterior declivity and with the transverse carina ending straight at the level of the spiracle.

Tegumental sculpture. Clypeus covered with sparse micropunctation and well marked moderately dense and coarse macropunctation. Body overall less dull, with sparser micropunctation. Macropunctation on head and mesosoma sharper and deeper. Posterior propodeal depression slightly shagreened in part. T1 with defined punctures on its anterior declivity. Macropunctation of S1 deeper. Remainder of metasoma with more evident macropunctation. Pilosity. Shorter, sparser and lighter.

MALE. Unknown.

Type material. Holotype Ƥ, BRAZIL: Rio de Janeiro, Nova Friburgo, 14–19.xi.2007 (P.C. Grossi) [ DZUP].

Distribution. Brazil: highlands of Rio de Janeiro.

Biology. The holotype bears several mites in its axillary fossae.

Etymology. The name of this species refers to its relatively large body size and T1 compared to other species in the group of S. apicipennis . In Argentinean jargon the term “grosso” means “generous friend”, indirectly referring to the collector of the holotype, my colleague and friend Paschoal Grossi.
