Tuberatra curvicauda n. sp.

( Figs. 1A–F )

Description. Female ( Fig. 2A ). Body length: 2.8 mm. Body color: head and mesosoma black; metasoma black, terga 3–7 dark brown at apex; scape and pedicel honey yellow, turning brown towards the apex of antennae; palps yellow; fore and middle legs with coxa, trochanter and trochantellus dark brown, femur brown, tibia and tarsus yellow; hind leg with coxa black, trochanter, trochantellus and femur dark brown, tibia and tarsus yellow; wing hyaline, venation and stigma brown, tegula dark brown; ovipositor sheaths brown; ovipositor light brown with black apex.

Head: clypeus smooth, with some setae inserted into punctuations; center of the face smooth and shiny, edges with some setae inserted into punctuations; frons smooth, shiny and slightly excavated behind the antennal insertion; vertex, temple and gena smooth and shiny; oral cavity circular, width approximately twice the malar space length; ocell-ocular distance twice the diameter of lateral ocellus; antenna with at least 14 flagellomeres (both antennae broken in holotype).

Mesosoma: pronotum rugose in dorsal view, pronotal groove scrobiculate, lateral area of pronotum coriaceous with smooth edges; propleuron mostly rugose, posterior apex smooth and with a ridge-like swelling in lateral view ( Fig. 2B ); mesoscutum declivous anteriorly; mesonotal lobes coriaceous, median mesonotal lobe with sharped lateral corners; notaulus scrobiculate, meeting at the end of mesoscutum ( Fig. 2F ); scutellar disk concave and slightly coriaceous; mesopleuron coriaceous, anterior and posterior edges smooth; subalar sulcus and mesopleural sulcus scrobiculate; precoxal sulcus thin, scrobiculate and complete ( Fig. 2C ); venter of mesosoma coriaceous; propodeum with two diverging carinae instead of a straight median carina, lateral carinae present; propodeum with a pair of small lateral spines ( Fig. 2E ); basal median areas coriaceous; propodeal areola rugose; metapleuron rugose-areolate.

Wings: fore wing vein r equal length to 3RSa; 2RS nebulous, and considered absent; 1cu-a distal to 1M; r-m present; first subdiscal cell open at the apex, 2cu-a absent; hind wing M+CU 0.6 the length of 1M vein.

Legs: fore tibia with a row of seven spines; medium tibia with a row of six spines; legs smooth, except for the hind coxa that is coriaceous; coxa angled at the base but without basal tubercle.

Metasoma: first metasomal tergum costate, length twice its apical width; dorsope present; basal sternal plate 0.4 length of first tergum; second metasomal tergum striate; suture between second and third tergum visible and straight; third metasomal tergum with a transverse groove, almost entirely striate, apical region smooth; fourth metasomal tergum smooth in the anterior basal region, striate after the groove that divides it, and smooth again in apical region; remainder of terga smooth and shiny ( Fig. 2D ); ovipositor slightly curved upwards, length about half the metasoma ( Fig. 2A ).

Male: same as female, except for the hind coxa dark brown; clypeus rugose; face slightly rugose; antennae with 16 flagellomeres; mesopleuron slightly coriaceous; metapleuron coriaceous; fifth metasomal tergum with a transverse groove slightly striated after this groove.

Distribution. Brazil (State of Amazonas and São Paulo).

Etymology. The specific name comes from the Latin curvus and the Latin cauda in reference to the curved ovipositor of this species.
