12. Probles (Euporizon) zacapoaxtlana Khalaim  , sp. nov.

( Figs 71–79View FIGURES 71–75View FIGURES 76–79)

Material examined. Holotype female ( TAMU), Mexico, Puebla, 3.7 mi. S of Zacapoaxtla , 23.VII.1985, coll. J. Woolley & G. Zolnerovich. 

Paratypes. MEXICO, Morelos: 1 ♀ ( UAT) Felipe Neri, 2270 m, 3.VIII.1996, coll. G. Peña. 

Description. Female. Body length 3.7 mm. Fore wing length 3.2 mm.

Head, in dorsal view, distinctly constricted and weakly rounded posterior to eyes ( Fig. 72View FIGURES 71–75); gena 0.85× as long as eye width. Eyes glabrous. Clypeus broad, 2.5× as long as broad, weakly convex in lateral view, with transverse impression in lower 0.3, with lower margin somewhat truncated, with distinct punctures on finely granulate background in upper 0.7 and smooth in lower 0.3, separated from face by distinct furrow. Palp formula 4+3. Mandible moderately slender, weakly tapered basally, with upper tooth somewhat longer than the lower. Malar space 0.8–1.0× as long as basal mandibular width. Antennal flagellum ( Fig. 73View FIGURES 71–75) robust, clavate, with 21–24 flagellomeres; subbasal flagellomeres 1.7–1.9× as long as broad and subapical flagellomeres distinctly transverse. Face with weak median prominence in upper part. Face and frons distinctly granulate, finely punctate (punctures mostly indistinct because of granulation), dull. Vertex finely granulate and very finely punctate. Gena very shallowly granulate, centrally almost smooth, weakly shining, with very fine inconspicuous punctures. Occipital carina complete. Hypostomal carina absent.

Mesosoma almost entirely granulate, almost impunctate, partly with very inconspicuous (because of granulation) punctures, dull; in holotype mesopleuron centrally (above foveate groove) smooth and shining, with fine but distinct punctures. Notaulus absent ( Fig. 72View FIGURES 71–75). Scutellum with lateral longitudinal carinae present in front 0.3. Foveate groove weakly oblique, almost straight, thin, with short transverse wrinkles, extending in front 0.8 of mesopleuron in holotype (short and situated in centre of mesopleuron in paratype). Propodeal spiracle separated from pleural carina by 0.5–1.0× diameter of spiracle. Propodeum in holotype mediodorsally with weak basal keel and fine longitudinal wrinkles, in paratype keel is almost completely obliterated ( Fig. 74View FIGURES 71–75); basal part about 0.6× as long as apical area; apical area flat, densely granulate, anteriorly narrowly rounded in holotype and widely rounded in paratype ( Fig. 74View FIGURES 71–75); apical longitudinal carinae complete in holotype and obliterated anteriorly in paratype.

Fore wing with second recurrent vein (2m-cu) postfurcal. Intercubitus (2rs-m) long, weakly thickened, about as long as abscissa of cubitus between intercubitus and second recurrent vein (abscissa of M between 2rs-m and 2mcu). First abscissa of radius (Rs+2r) almost straight, longer than width of pterostigma. First and second abscissae of radius (Rs+2 r and Rs  ) meeting at right angle. Metacarpus (R1) not reaching apex of fore wing. Second abscissa of postnervulus present, thus brachial cell is closed posteriorly. Hind wing ( Fig. 75View FIGURES 71–75) with nervellus (cu1&cu-a) slightly reclivous, subvertical. Legs slender. Tarsal claws not pectinate, strongly curved at apex.

First tergite 2.9× as long as posteriorly broad, with upper margin in lateral view rather evenly convex, with slight concavity in apical 0.6 ( Fig. 77View FIGURES 76–79); petiole almost entirely striate laterally and dorsally (dorsally smooth at base), posteriorly very shallowly sculptured basally and smooth posteriorly; postpetiole weakly widened in dorsal view ( Fig. 78View FIGURES 76–79). Glymma deep, situated in posterior 0.6 of tergite, joining by distinct furrow to ventral part of postpetiole ( Fig. 77View FIGURES 76–79). Second tergite about 1.2× as long as anteriorly broad ( Fig. 78View FIGURES 76–79). Thyridial depression oval, 1.5× as long as broad, with posterior end rounded ( Fig. 78View FIGURES 76–79). Ovipositor short and robust, weakly bent upwards (stronger upcurved at apex), with shallow dorsal subapical depression ( Fig. 79View FIGURES 76–79); sheath 1.1–1.3× as long as first tergite. Head, mesosoma and first metasomal tergite black; clypeus yellow-brown in lower 0.4. Palpi and mandible (teeth reddish to reddish black) yellow to brownish yellow. Scape and pedicel of antenna brownish yellow to brown; flagellum black, basally brownish. Tegula brownish. Wings slightly infumate with brown. Pterostigma brown. In holotype legs brownish yellow; all coxae extensively darkened with brown (hind coxa brownish black), yellowish at apex; all trochanters yellow; fore and mid femora centrally brownish; hind femur brown, yellowish at extreme base and apex; hind tibia and tarsus brownish. In paratype legs uniformly brownish yellow with only hind coxa brown and hind tarsus fuscous. Metasoma posterior to first tergite predominantly dark brown, yellow-brown ventrally; second tergite dorsally with brownish yellow transverse band on hind margin ( Fig. 78View FIGURES 76–79). Male. Unknown. Etymology. The species is named after the type locality, Zacapoaxtla. Distribution. Mexico (Morelos, Puebla). Comparison. The new species differs from all other Mexican species of Probles by its strongly clavate antenna with subapical flagellomeres distinctly transverse (Fig. 73), and short second metasomal tergite (Fig. 78).
