Tetraglossula fucosa (Michener, 1989)

( Figures 4 , 5 , 14 M–P, 15J–L)

Leioproctus (Tetraglossula) fucosus Michener, 1989 , 697. Type data: holotype SEMC ♂ (examined), paratypes SEMC ♀ ♂, paratypes DZUP ♀ ♂, paratype USNM, paratype AMNH; type locality: Brazil, São Paulo, São Carlos. Tetraglossula fucosa ; generic combination by Moure, Graf & Urban 1999.

Diagnosis. This species and T. meloi are distinct from all remaining Tetraglossula species for the metasoma largely or partly orange or red. Specimens of T. fucosa are generally shorter than 10 mm, wings are hyaline ( T. meloi are larger and more robust bees, wings are fuscous). The male S7 of T. fucosa with a broad trapezoid basal lobe ( Fig. 14 N; see comments below), only comparable to that of T. anthracina , whose general appearance is completely distinct from that of T. fucosa ( T. anthracina are black bees, the pubescence is all black or dusky).

Male genitalia and hidden sterna S6–S8: Figs 14 M–P, 15J–L. Line drawings of male T7, S6–S8 and genitalia can be found in Michener (1989, Fig. 13 A–I). Basal lobe of S7 ( Fig. 14 N) broad, less pilose that in T. anthracina , and trapezoid, partly superposed with the apical lobe; medial sclerotized region positioned proximally to apical and basal lobes of S7 short. Apical lobe of S8 subequal to disc of S 8 in profile ( Fig. 14 P).

Distribution ( Fig. 19 ): BOLIVIA: Beni (San Borja [USNM:1]); BRAZIL: Minas Gerais (Estrela da Barra [RPSP:1], Uberlândia [UFMG:4]), Pará (Cachimbo [SEMC:14]), São Paulo (Itirapina [RPSP:12], São Carlos [AMNH:2, BBSL:2, SEMC:18]); PARAGUAY: Cordillera (San Bernardino [USNM:1]). Specimens from Pará state ( Brazil) were reported to have “antenna and legs largely red, the metasoma entirely yellowish red except the blackish spot at side of T2 or T4-7 of male are largely blackish, and the dusky and blackish hairs are paler” than in specimens from the type locality (Michener 1989, 697). The records for Bolivia and Paraguay are based on a single female specimen each [USNM] do not appear to have significant morphological differences from individuals from the type locality, other than color variation (slightly lighter color in the female from San Borja and darker in the specimen from San Bernardino).
