Diagnosis

This new species is similar to S. glabrifovea Fischer, 1967 ( USA), but differs from it in having the prescutellar pit present (absent in S. glabrifovea ), face 2.1 times as long as high (3.0 times in S. glabrifovea ), mandible 1.8 times as long as its maximum width (1.5 times in S. glabrifovea ), and the first metasomal tergite 2.4 times as long as its apical width (2.1 times in S. glabrifovea ).

Etymology

The specific epithet refers to “ Brazil ”, after the country where this species was found.

Material examined

Holotype BRAZIL: ♀, Nova Teutonia, 27º11′ S, 52º23′ E, 10 May 1938, F. Plaumann leg. ( BMNH: B.M. 1938– 682 ).

Paratypes BRAZIL: 1 ♀, 1 ♂, same locality, but 27º S, 52–58º E, 28 May and 1 Jun. 1938, F. Plaumann leg. ( BMNH: B.M. 1938–458 ).

MESOSOMA. In lateral view 1.2 times as long as high. Mesoscutum (dorsal view) 0.9 times as long as its maximum width, with sparse setae arranged as single line along notaulus line. Notauli mainly absent on horizontal surface of mesoscutum. Mesoscutal pit present and elongate. Prescutellar depression smooth, without lateral carinae, 1.1 times as long as its maximum width. Precoxal sulcus present, crenulate, not reaching anterior and posterior margins of mesopleuron. Posterior mesopleural furrow smooth. Propodeum with pentagonal areola crossed by complete and distinct median longitudinal carina from its base to apex. Propodeal spiracles relatively small, its diameter 0.2 times as wide as the distance from spiracle to anterior margin of propodeum.
