MATERIAL EXAMINED. — Holotype. Brazil • ♂; São Paulo: Est. de São Paulo, Val. Du Rio Pardo ; E. Gounelle; MNHN-EH-EH25369 (high-resolution images, Fig. 2E, F ).

DIAGNOSIS. — Coloration red, with apex of thoracic spines yellow; antennae, coxae, trochanters and femora reddish ( Fig. 2F ); posterior margin of pygophore flat; posteromedial process of pygophore deeply concave medially, ramus curved and laterally projected ( Fig. 5B ).

DISTRIBUTION. — Brazil (São Paulo) ( Villiers 1943a, b) ( Fig. 7).

REDESCRIPTION

Male

Macropterous. Measurements in Table 2 .

Coloration ( Figs 2E, F ). Head: Red. Scape and pedicel reddish, basi- and distiflagellomeres pale brown. First and second visible labial segments reddish, third visible labial segment yellowish. Thorax: Reddish. Proleg reddish, except apical portion of protibia and tarsus yellowish; meso- and metalegs similar to prolegs. Forewing pale brown with veins and pterostigma reddish. Abdomen: Reddish, medial region of the abdominal sternites pale brown.

Structure. Thorax ( Fig. 2F ): Humeral angle spines long, three times longer than their base. Mesonotal spine straight, three times longer than its base. Protuberance of scutellum with its apex slightly concave and conspicuously concave posteriorly, lateral margins conspicuously expanded in caudal view. Metanotal spine straight, 0.2 times the length of mesonotal spine. Forewing with two closed cells, apex of outer discal cell extending as far as apex of pterostigma. Abdomen: Abdominal segment 2 not conspicuously narrower than posterior segments. Genitalia: Posterior margin of pygophore flat, and densely setose. Posteromedial process of pygophore (mpp) deeply concaved medially. Ramus curved and projected laterally, nearly twice as long as its base, apical region narrowed with an acute and projected apical process ( Fig. 5B ).

REMARKS

Saica carayoni is known only by the holotype. This species is similar to S. rubripes , because both species have the basal process of the scutellum inverted scoop-shaped and deeply emarginated in caudal view. However S. carayoni shows the posterior margin of pygophore flat ( S. rubripes has a pair of protruding processes); and the ramus of the posteromedial process of pygophore is longitudinally angulated (in S. rubripes is nearly straight).
