(Figs 16–22)
Material examined. Holotype: BRAZIL. São Paulo: 1 ³ (DCBU 208470), Luiz Antônio, Estação Ecológica do Jataí, 21°36.25’S 47° 47.66’W, 565 m, Malaise 2, 27.ix–09.x.2014, A. S. Soares col. Condition of type: intact, except distal two flagellomeres of right antenna and left tarsus are missing.
Paratypes: 5 ³ (DCBU 209797; 209799; 352202; 352203; 352205) and 1 ³ (DCBU 208469) same as holotype; 1 ³ (DCBU 352204), same as holotype except 27.iv.2014; 2 ³ (MZSP) same as holotype except, 11.xi.2014.
Diagnosis. Boethella jatai sp. nov. is the only species in which the auxiliary carina of the mesopleuron curves strongly dorsally, so that it runs parallel to the anterior edge of the mesopleuron (Fig. 18) (mostly straight in all other species). It also has the deepest glymma of any species and is the darkest species. It is the only species with black in any of the following areas: vertex, propodeum, T1 of metasoma and hind femur. In all other species, these structures range from yellow to dark brown.
Description. Male. Fore wing length 4.2–4.3 mm.
Head. Mostly smooth and shiny, finely and sparsely punctate and with long pilosity, genae moderately glabrous; mandibular teeth about same length, sometimes lower tooth slightly longer; antenna with 20–21 flagellomeres, first flagellomere 3.0–3.3× as long as width and 1.1–1.3× as long as the second flagellomere; lateral ocelli separated from eye 1.8× their own diameter and 0.9× from each other; face 1.8× as wide as high; clypeus flat, about 3.5–3.7× as wide as high, its apical margin truncated (Fig. 17); malar space obliterated, base of mandible contiguous with ventral edge of eye.
Mesosoma. Mostly smooth and shiny, finely and sparsely punctate and with long pilosity, areola of propodeum, mesopleuron and pronotum centrally glabrous; mesopleuron 0.7–0.8× as long as high; scutellum with lateral carinae absent; epicnemial carina reaching near the mid-posterior margin of the pronotum; auxiliary carina of mesopleuron curving strongly dorsally, not joining epicnemial carina (Fig. 18); sternaulus present as a weak depression; propodeum with all carinae present and strong except the sublateral abscissae of the anterior transverse carina (= costulae) absent (Fig. 19), spiracle circular, distant from pleural carina by 3.0–3.5 × its own diameter; fore wing (Fig. 20) with Rs + M strongly curved and slightly distad from cu-a; hind wing (Fig. 21) with Rs spectral apically, 1A absent apically and with 5–6 distal hamuli; tarsal claws pectinate to apex.
Metasoma. Mostly smooth and sparsely pilose; first tergite 1.7–1.9 × as long as apically wide, spiracle at about 0.6 of length, glymma present, dorsal and dorsolateral carinae lacking; T2 subquadrate and T3+ rectangular, thyridium present.
Coloration. Head mostly yellowish white, except mandible teeth dark brown, labial and maxillary palpi apex slightly orange, gena, occiput and antennae black, except apical flagellomeres dorsally white and scape and pedicel ventrally yellowish white. Mesosoma predominantly orange, except propodeum black, axillary trough of metanotum and of mesonotum, tegula, pronotum basally and apically and mesopleuron apically yellowish white (mesoscutum, pronotum and mesopleuron sometimes darker with brown to black spots). Anterior and mid legs orange except coxa, trochanter and trochantellus white, tarsomeres apically slightly darker to light brown; posterior legs with femur, tibia and tarsus dark brown to black, tibial spurs yellowish white, coxa, trochanter and trochantellus yellowish with brown spots. Wings hyaline, apically slightly infuscate, pterostigma brown. Metasoma with tergites black, T2+ apically white, sternites white, subgenital plate dark brown to black laterally.
Female. Unknown.
Distribution. Brazil: S„o Paulo State (Fig. 22).
Host. Unknown.
Etymology. The specific name refers to the Estação Ecológica do Jataí where this species was collected.
Comments. Brazilian species have been collected predominantly in areas of rain forests, Amazonian and Atlantic Forest (Fig. 22). Specimens of Boethella jatai sp. nov. were sampled in a savanna area (cerrado sensu stricto), but mostly in the wet period.
