Frons shallowly reticulate to reticulate-imbricate ( Fig. 2b ); vertex, alutaceous to alutaceous-imbricate; scrobal depression extensively coriaceous to reticulate; lower face with conspicuous white lanceolate setae ( Fig. 2b ); antenna with toruli distinctly above lower eye line; scape reaching above anterior ocellus; pedicellus plus flagellum about 1.3× breadth of head, flagellum proximally stouter than pedicellus, almost filiform; pedicellus 1.4× as long as broad; anellus 2.5× as broad as long; Fl–2 1.1× longer than wide; F3–F7 wider than long; clava 1.5× as long as broad; sensilla dense, in 2 rows ( Fig. 2c ).

Mesosoma slightly bulged in profile, propodeum declined ( Fig. 2a ), distinctly visible from above; thoracic dorsum entirely evenly reticulate, midlobe of scutum equal to length of sidelobe; frenum not delimited, distinguished by a difference in sculpture; frenal groove absent medially, indicated slightly laterally; lanceolate setae on anterior scutellum, notauli distinct as fine grooves ( Fig. 2d ). Mesepimeron broad and almost 2× higher than broad; propodeum sloping sharply and overhung by scutellum, with very weakly alutaceous-reticulate sculpture ( Fig. 2e ); forewing upper surface of costal and admarginal cell bare, speculum open broad, basal vein without setae, triradiating setal rows distinct ( Fig. 2g ); hind leg with hind coxae stouter, dorsal surface bare in basal half, ofen with a longitudinal curved carina; hind femur is 3.5× as long as broad and with a distinct denticle beneath ( Fig. 2f ); hind tibia with 2 apical spurs, the longer spur slightly longer than breadth of tibia and 0.43× as long as first segment of tarsus ( Fig. 2f ); the shorter spur 0.74× length of second spur.

Metasoma dorsally flattened, terga I and II incised, tergum III with a small incision and tergum IV slightly incised about 1/4 or less visible length of tergum ( Fig. 2h ); ovipositor 2.3× length of the abdomen ( Fig. 2a ).

MALE ( Fig. 3 ): Similar to female ( Fig. 2a ) except antenna with flagellum proximally distinctly stouter than pedicellus ( Fig. 3b ); pedicellus 1.12× as long as broad; anellus 2× as broad as long; sensilla dense, in 1 row; fore and hind femur distinctly enlarged.

ETYMOLOGY: The name moazopi is a combination of the first letter of each of the localities where the specimens were collected.

REMARKS: Torymus moazopi can be placed in the tubicula group by the following features: sessile (sometimes subsessile) stigmal vein, wing relatively sparsely setose, hind coxa dorsally glabrous, and frenal groove distinct at least laterally. Within the tubicula group, T. moazopi is morphologically closer to T. atheatus Grissell ; however, T. moazopi can be distinguished from the latter species by the long ovipositor which is 2.7 mm (1.1 mm in T. atheatus ), and thorax color which is mainly dark metallic blue with coppery hues (dark metallic green in T. atheatus ). Also, males of the new species can be distinguished from those of T. atheatus by their distinctively wide fore and hind femora.

BIOLOGY – Among the specimens of T. moazopi n. sp., other parasitoids belonging to different taxa emerged. We assume that they also are primary parasitoids of Bruchinae because no other host species emerged from the seeds. All taxa collected from Phaseolus at different sampling sites are presented in Table 1.
