( Fig. 326 )

* Messatoporus femorator Kasparyan & Ruíz 2005: 107 , 112. Description, distribution, keyed. Holotype ♂ (UATM, pictures examined). Type data: México, Tamaulipas, Gómes Farías, Alta Cima, 900 m, Malaise trap, 3–10.VII, S. Hernández A. Messatoporus femorator: Kasparyan & Ruíz 2008: 308–309 , 312, 318–320. Description, distribution, figure, keyed.

Female. Unknown.

Male. Fore wing 8.10 mm. HEAD: Antenna with 26 flagellomeres; flagellum subapically slightly compressed; all flagellomeres except apical one ventrally covered by dense and coarse setae.

THORAX: Pronotum glabrous, shiny, epomia apparently moderately strong, distinct only after diverging from pronotal collar, short, ending far from dorsal margin of pronotum, after diverging from pronotal collar approximately straight. Mesoscutum strongly and uniformly curved, shiny. Subalar ridge moderately projected; epicnemial carina complete, reaching subalar ridge; sternaulus moderately strong, wide and shallow at posterior 0.25, strongly sinuous. Transverse sulcus at base of propodeum apparently very wide.

PROPODEUM: Shiny. Propodeal wrinkles strong, closely spaced; posterior transverse carina represented by very weak sublateral ridges.

WINGS: Fore wing vein 1-Rs+M distinctly sinuous; crossvein 1m-cu more or less uniformly curved, limit between 1m-cu and 1-Rs+M more or less traceable; vein 2Cua much shorter than crossvein 2cu-a; cell 1+2Rs small; crossvein 3r-m present, 2r-m and 3r-m apparently subparallel; vein 3-M much shorter than 2-M; 4-Rs distinctly sinuous; 4-M slightly curved backwards. Hind wing vein 1-M forming straight angle with vein Cua; Cua slightly longer than 1-cua 1.02; vein Cub distinctly convex on posterior half, forming straight angle with cu-a.

METASOMA: First tergite short, about 0.32 × as long as T2–8, approximately cylindrical; spiracle at about 0.55 of its length; median depression distinct; thyridium apparently longer than wide, without small circular depression just behind it.

Color. Head, meso- and mesosoma black and pale yellow. Head: black; clypeus, mandible except apex, mouthparts, malar space, supra-clypeal area, small ventral spot at scape and complete orbital band, pale yellow (237,224,116); f11–15 entirely white dorsally, f10 and f16 partially white. Mesosoma: mostly pale yellow; mesoscutum except subcircular spot, scuto-scutellar area, apex of scutellum, both axillary through, postscutellum, epicnemium dorsally, scrobe and hypoepimeron, posterior spot on metapleuron, transverse sulcus and propodeum except arc-shaped mark, black; fore and mid coxa and trochanters, pale yellow; mid first trochanter longitudinal blackish stripe; fore and mid femora, tibiae and tarsi light orange, femora with dorsal brownish marks, tibiae with basal brownish marks; fore t5 blackish; hind coxa pale yellow with anterior and posterior longitudinal blackish stripes, anterior one only on basal 0.5; hind first trochanter pale yellow with ventral longitudinal blackish stripe; second trochanter blackish; hind femur femur orange with dorsal face entirely, basal 0.3 and apical 0.25 of lateral face blackish; hind tibia light orange, basal 0.05 and apical 0.2 blackish; basal 0.4 of t1 blackish, remainder of tarsus light yellow, apically gradually turning to whitish. Metasoma: mostly blackish; anterior 0.4 and posterior 0.2 of T1, pale yellow; S1 pale yellow; T2–7 with apical, progressively wider, light yellow stripe.

Comments. Recognized by the dorsal margin of mesopleuron entirely yellow, hind femur mostly blackish and S1 black. Another notable character is the dense and coarse setae covering all flagellomeres except the apical one. The dorsal margin of mesopleuron yellow is an unusual feature among species of Messatoporus , found only in M. maculipes , M. elektor sp. nov. and M. atrifoveus sp. nov. The hind femur has a color pattern more or less similar to that found in M. complexifemur sp. nov. and M. tenuissimus sp. nov. The male holotype is the only known specimen.

Biology. Unknown.

Material examined. Pictures of the holotype. Pinned. Mid tarsi missing; otherwise apparently in good shape.

Distribution. Recorded only from the type locality, in northeastern Mexico ( Fig. 326 ).
