Digonocryptus thoracicus Kasparyan et Ruíz, 2005:176 . ♀, ♂ Description, keyed, figure. Holotype at Universidade Autonoma de Tamaulipas, Cd. Vitoria, Tamaulipas, Mexico (not examined).

Description. FEMALE. Fore wing 11.0 mm.

Head. Ventral tooth of mandible approximately as long as dorsal tooth. Clypeus apical area delimited by smooth border; clypeal margin with two weak teeth. Antennae missing.

Mesosoma . Mesopleuron with dense white pilosity covering about 80% of cuticular surface. Subalar prominence large and round, suboval ( Fig. 144). Sulcus between sternaulus and scrobe absent. Posterior transverse carina of mesosternum represented by short and distinct carina crossing discrimen. Carinal triangle and lower metapleuron entirely, and propodeum from anterior carina to apex, with thick dense white pilosity covering almost 100% of surface. Lower metapleuron finely rugulose. Propodeum: area in front of anterior transverse carina polished, smooth, medially with two incomplete ridges extending from carina towards anterior margin. Propodeal apophyses present as scale-like structures, continuous with distinct and bell-shaped posterior transverse carina. Area between transverse carinae obliquely and strongly striate-rugose; area behind posterior transverse carina rugose. Fore wing in Fig. 211; vein 3-Cu 1.45 length of 4-Cu. Hind wing in Fig. 251.

Metasoma. Postpetiole dorso-anteriorly flat; dorsolateral and median dorsal carina absent; petiolar spiracles in dorsal view not prominent. Ovipositor 1.29 length of hind tibia. Apex of lower valve with 13 teeth.

Color. Black and light yellow. Lateral pattern as in Fig. 73. Orbital band complete, except distinctly interrupted at malar space, from about 6–7 h, width on supra-antennal area and temple 0.25 of interocular distance, covering all of gena. Supraclypeal area mostly yellow, except narrowly black medio-longitudinally through its entire length. Clypeus yellow, except black apical area; clypeal sulcus concolorous with clypeus. Mesosoma dorsally black, except as follows. Pronotum along anterior margin with wide yellow stripe from side to side, apparently interrupted medially (polyvinyl adhesive covering area), laterally on dorsal margin with large suboval yellow spot. Propleuron on basal half with large subtriangular yellow spot. Mesoscutum uniformly black. Scutellum entirely yellow. Postscutellum black. Propodeum as in Figs 73–74. All femora changing gradually from basally dark brown to apically and mesally yellow. All tibiae yellow, hind tibia apically dark brown. Fore and mid t1 brownish yellow, remaining fore tarsomeres brown, remaining mid tarsomeres dark brown. Hind t1 basal 0.3 brownish yellow, t1 otherwise and entire t2–3 white, t4–5 dark brown. Metasoma dorsally black, except as follows (Fig. 102). Postpetiole entirely yellow. T2–3 apical margin with yellow stripe wide, uniform width on T2, becoming slightly wider laterally on T3. T4–7 apically with yellow stripe, narrowest on T6, widest on T7. T8 apically with one yellow spot on each side.

Morphological variation. Fore wing 6.4–11.0 mm. Antenna with 24–25 flagellomeres; white band starting at flagellomere V, with 7 articles. Ovipositor 1.0–1.29 length of hind tibia. Scutellum apically black.

MALE. Similar to female. Most important differences are clypeus, supraclypeal area, gena, temple and prosternum entirely pale yellow; basal and apical ends of hind femur and basal two-thirds of hind t1 dark brown; postscutellum entirely yellow; metasoma with all yellow stripes very wide, with similar and regular width.

Comments. Similar to D. grossipes (Brullé) , from which it can be readily separated by having mesepimeron entirely yellow (vs. entirely black), coxae yellow with black marks and trochanters black (vs. coxae and trochanters orange), speculum largely covered by mesopleural sculpture (vs. polished, smooth), and by distinct pattern of yellow stripes of metasoma (compare Figs 73 vs. 33).

The male is very similar to some males of D. grossipes , from which the present species can be distinguished by having T1 dark with yellow on apex (vs. yellow basally and apically) and hind coxa with longitudinal stripes of yellow and black (vs. uniformly colored, at most with yellow spot dorsally).
