Clypeus 1.44 as wide as high, subtriangular, finely punctate; apex 1.67 as long as base, truncate; apical margin sharp, medially slightly concave. Supraclypeal area medially strigate, laterally finely punctate, densely pilose, medially with longitudinal subrectangular prominent area; between antennal foramens with U-shaped carina; radicle foveolate. Antenna with 22 flagellomeres; white band starting at flagellomere 5, reaching flagellomere 18; flagellum slender. Supra-antennal area without distinct median carina, medially without longitudinal elevation, near antennal sockets not striate; dorsal half medially rugulose. Paraocular area smooth. Vertex rugulose around ocelli, without sulcus; gena and vertex behind ocelli minutely strigulate, sparsely pilose; gena in lateral view uniformly wide; occipital carina stout, dorsally uniformly arched, ventrally markedly projected as crest, reaching hypostomal carina far from mandible base; hypostomal carina projected as crest; malar space 1.07 as long as basal width of mandible.

Mesosoma . Mesosoma in dorsal view 2.08 as long as wide; in lateral view, mesosoma middle width 0.16 mm. Pronotum centrally smooth, latero-ventrally rugose behind collar, margin near mesopleuron not corrugated; pronotal swelling strigulate; collar dorso-laterally carinated, not swollen, anteriorly smooth; epomia stout, restricted to space between posterior margin of collar and pronotal swelling. Mesoscutum sparsely pilose, densely punctulate, covered with sparse coarse punctures, impression of notaulus corrugated, central lobe without longitudinal sulcus or carina; notaulus moderately impressed, posteriorly parallel throughout. Scutoscutellar groove smooth, polished; scutellum 0.96 as long as wide, smooth; scutellar carina incomplete, restricted approximately to anterior 0.3; postscutellum 0.44 as long as wide; hind margin of metanotum with two lateral teeth. Subalar ridge somewhat elongate; mesopleuron dorsally medially markedly strigate, ventrally strigulate; mesopleural groove corrugated; epicnemial carina stout, dorsally curving backwards; dorsal end of epicnemial carina reaching 0.1 of posterior margin of pronotum, behind epicnemial carina without rounded confused-rugulose area; sternaulus medially shallow, interrupted, reaching base of mid coxa, markedly sinuate, deeply impressed, faint from anterior 0.7 to 0.8, faintly corrugated; scrobe deeply impressed, forming pit. Mesothoracic venter strigulate; median portion of posterior transverse carina of mesothoracic venter convex, regularly shaped, without projections. Transverse furrow at base of propodeum laterally 0.21 as long as anterior portion of propodeum, shallow and narrow, medially wide, uniformly corrugated; propodeum 1.27 as long as wide medially; anterior margin of propodeum with two faint lateral teeth; anterior portion of propodeum strigulate or with sparse coarse punctures, medially with two parallel longitudinal carinae; lateral longitudinal carina of propodeum indistinct; posterior portion of propodeum strigate, progressively coarse toward posterior margin, medially without distinctly stout longitudinal carina; behind posterior transverse carina with two divergent longitudinal carinae; anterior transverse carina of propodeum complete, stout, medially markedly arched forwards; posterior transverse carina absent, only with lateral slight swellings; propodeal spiracle 1.33 as long as wide; pleural carina of propodeum complete, moderately stout; lower division of metapleuron strigulate, densely pilose, juxtacoxal carina short and faint.

Wings. Fore wing: vein 2+3Rs almost straight; ramellus absent; vein 1M+Rs posteriorly faintly sinuous; vein 1cu-a straight, arising far from vein 1M+Rs base, angle with vein M+Cu about 90°; vein 2Cu 0.44 as long as vein 2cu-a; vein 4Rs 0.94 as long as vein 4M, slightly sinuous, almost straight; cell 1+2Rs 0.73 as high as pterostigma, rectangular; vein 2M approximately as long as vein 3M; vein 3M distinct, 1.00 as long as vein 2M. Hind wing: vein 1Cu 1.41 as long as vein cu-a; vein 2-1A reaching 0.75 of distance to posterior margin.

Legs. Tibia with very sparse short bristles; hind coxa globose.

Metasoma. T1 0.65 as long as hind femur, without basolateral tooth; anteriorly smooth, posteriorly coriarious; spiracle at anterior 0.51, prominent; postpetiole dorso-anteriorly convex; T2–8 minutely coriarious; almost glabrous; T2 1.12 as long as wide at apex; apex of T2 2.28 as wide as base. Dorsal valve of ovipositor with nodus indistinct; apex of lower valve without teeth; notch absent.

Color. Head, mesosoma and metasoma black, dark brown and bright yellow. Head: bright yellow (235,197,081); interocellar area, vertex and gena, except complete large orbital band, and occiput, dark brown (105,042,016); scape and pedicel, bright yellow. Mesosoma : propleuron bright yellow; pronotum bright yellow, with transverse central dark brown stripe; mesoscutum black, except almost entire central lobe and anterolateral rounded spot at lateral lobe, bright yellow; mesopleuron bright yellow with dark brown mark anteriorly around hypoepimeron; remainder of mesosoma bright yellow, except for the following black marks: both axillary trough of mesonotum and metanotum, carinal triangle, anterior portion of propodeum, and three lateral longitudinal marks at propodeum: medially and along pleural carinae. Legs: yellow; all t5 dark brown; mid coxa dorsally with small apical brown spot; hind coxa dorsally with anchor-shaped mark at entire length. Metasoma: brown and bright yellow; T1 and S1 brown, anterior and posterior 0.1 bright yellow; T2–8 brown with posterior 0.4 yellow; S2–8 bright yellow.

Comments. Very similar to T. vinhaticus sp. nov., from which it differs by having central lobe of mesoscutum without sulcus or carina (vs. with faint longitudinal carina in T. vinhaticus sp. nov.); posterior portion of propodeum without distinctly stout longitudinal carina (vs. medially with swollen longitudinal carina; Fig. 150 View FIGURES 145–150 ); yellow mark at lateral lobe of restricted to 0.2 anterior (vs. mesoscutum reaching well beyond tegula; Fig. 85 View FIGURES 85–90 ); pleural carina complete, moderately stout, as in Fig. 41 View FIGURES 41–44. 41 (vs. irregular and faint, obsolescent posteriorly, fused with sculpture of propodeum and lower division of metapleuron); transverse furrow at base of propodeum laterally narrow (vs. wide; Fig. 150 View FIGURES 145–150 ); T1 almost entirely black, except for anterior and posterior 0.1, bright yellow (vs. T1 light yellow, with black mark restricted to spiracle level; Fig. 181 View FIGURES 175–186 ).

Male. Unknown.

Distribution. Mexico. The type locality “Tumazula” refers to Tumazula, Durango, in Mexico (24°56’N 104°54’W) ( Fig. 220 View FIGURES 216–223 ).

Biology. Unknown.

Material examined. Holotype ♀, Tumazula, 13–16.VIII.1913 ( AMNH). Antennae beyond scape, right fore and hind legs beyond coxa, left mid leg, and right hind leg beyond tibia, missing; left wings ripped; axillary trough of mesonotum somewhat damaged by pin.
