Diagnosis

This new species is similar to S. magnioculis sp. nov. but differs from it in having the eye in lateral view 1.5 times as long as temple medially (1.7 times in S. magnioculis sp. nov.), face 1.8 times as long as high (1.2 times in S. magnioculis sp. nov.), second flagellar segment 2.2 times as long as its maximum width (2.7 times in S. magnioculis sp. nov.); sixth segment 1.8 times (2.5 times in S. magnioculis sp. nov.), and hind femur 3.5 times as long as its maximum width (3.9 times in S. magnioculis sp. nov.).

Etymology

Named after Fritz Plaumann, collector of the type material of this new species.

Material examined

Holotype BRAZIL: ♀, Nova Teutonia, 27º11′ S, 52º23′ E, 20 Aug. 1937, F. Plaumann leg. ( BMNH: B.M. 1937– 748 ).

Paratypes BRAZIL: 3 ♀♀, 1 ♂, same locality as holotype, but 19 Mar., 5 Jul., 31 Aug. 1937 and 2 Jun. 1938 ( BMNH, ZISP: B.M. 1937–424 ; 1937–656 ; 1937–748 ; 1938–458 ).

Face 1.8 times as wide as high, completely covered by numerous setae; inner margins of eyes subparallel. Clypeus 2.5 times as wide as high, slightly concave ventrally. Paraclypeal fovea short, reaching 0.4 times distance between clypeus and eye. Mandible weakly widened towards apex, 1.5 times as long as its maximum width. Upper tooth very small, shorter than lower and middle teeth; middle tooth short, wide basally and pointed apically; lower tooth short, rounded. Antennae 23-segmented, 1.1 times as long as body. Scape 2.5 times as long as pedicel. First flagellar segment 3.6 times as long as its apical width, 1.4 times as long as 2nd segment. Second and 3rd flagellar segments 2.0 times, 4th to 8th segments 1.8 times, 9th to 18th segments 2.0 times, 19th and 20th segments 1.8 times, and 21st (apical) segment 2.2 times as long as their maximum width.

MESOSOMA. In lateral view 1.3 times as long as high. Mesoscutum (dorsal view) as long as its maximum width, with numerous setae arranged in middle part of mesoscutum. Notauli mainly absent on horizontal surface of mesoscutum. Mesoscutal pit present and elongate. Prescutellar depression smooth, without lateral carinae, twice as long as its maximum width. Precoxal sulcus present, crenulate, not reaching anterior and posterior margins of mesopleuron. Posterior mesopleural furrow smooth. Propodeum sculptured, with complete and distinct median longitudinal carina from its base to apex and with several transverse carinae reaching sides of propodeum. Propodeal spiracles small, its diameter 0.1 times as wide as the distance from spiracle to anterior margin of propodeum.
