Thygater tuberculata Urban 1967

Thygater (Nectarodiaeta) tuberculata Urban 1967 ; Urban, Moure & Melo 2012.

Diagnosis. T. tuberculata (male) has four maxillary palpomeres and almost entirely fuscous pilosity. It can be easily distinguished by the following combination of characters: the hind basitarsus with apical margin project beyond articulation of 2nd tarsomere; the tubercle on the disc of S4 (absent in all other species) and by the tubercles on S6, one medially and another two laterally.

Description ♀: unknown.

♂ (holotype): Integument black, except for reddish areas on mandibles, malar area, head, mesepisternum, legs and mesosoma, amber-translucent on apex of marginal zones; marginal zone of T1 with translucent amber area short, short as F1 length, marginal zone of T2 – T5 longer than F1. Pilosity fuscous, except white on head (except on small areas of vertex, paraocular areas and frons), apical margins of mesoscutum, T1 basally, yellowish on edges of T4 – T7; forming complet apical fringe on S4; on S5 forming lateral tufts; on S6 with dense plumose pilosity, especially on apex and on longitudinal line. Structure malar area about ½ as long as basal mandibular width; clypeus with mid-longitudinal elevation on disc, not forming a carina; its basal depression reaching 1/5 of clypeal length; hind basitarsus with apical margin project beyond articulation of 2nd tarsomere; apex of T7 shallowly emarginate, forming two broadly flat rounded lobes; S4 with a small discal tubercle; S5 with two marginal dentiform projections; S6 with a median and two lateral tubercles.

Holotype (male): “holótipo” “Itatiaia; R. Janeiro—Brasil; Fevereiro 1959; W. Zikan” “ Thygater ; tuberculata ; D. Urban det. 67” [DZUP]—examined.

Habitat: unknown.

Additional material examined: none.

Distribution in Minas Gerais: This species has not been recorded yet in the state. However, since it occurs in the Serra da Mantiqueira in the state of Rio de Janeiro, near the border of Minas Gerais, it seems reasonable to expect that it also occurs in similar environments in the southeastern region of this state.

Flower records: unknown.
