Description. Female. Body length 3.0 mm. Fore wing length 3.0 mm.

Head, in dorsal view, distinctly constricted and weakly rounded posterior to eyes ( Fig. 64 View FIGURES 62–66 ); gena 0.85–0.9× as long as eye width. Eyes with short setae ( Fig. 64 View FIGURES 62–66 ). Clypeus lenticular in front view, 3.3× as broad as long, flat or weakly convex centrally, with more or less distinct transverse ridges laterally, smooth in lower part and scabrous in upper part, with fine to rather strong punctures in upper part, separated from face by broad furrow. Palp formula 4+3. Mandible moderately slender, weakly tapered in basal half, distinctly punctate in basal 0.6–0.7; upper tooth somewhat longer than the lower. Malar space about as long as basal mandibular width ( Fig. 63 View FIGURES 62–66 ). Antennal flagellum ( Fig. 63 View FIGURES 62–66 ) moderately robust, with 21–23 flagellomeres (21 in holotype); mid flagellomeres 1.2–1.3× as long as broad, subapical flagellomeres quadrate or slightly elongate. Face with weak median prominence. Face granulate, dull, with inconspicuous punctures laterally. Frons granulate, impunctate, dull. Vertex finely granulate, dull or weakly shining, with very fine inconspicuous punctures. Gena very shallowly granulate, centrally almost smooth, weakly shining, with very fine punctures. Occipital carina complete.

Mesoscutum granulate, dull, with very fine inconspicuous punctures. Notaulus without distinct wrinkle on anterolateral side of mesoscutum, but with conspicuous deep impression distant from anterolateral margin of mesoscutum and crest before this impression. Scutellum with lateral longitudinal carinae in its front 0.2–0.3. Mesopleuron shallowly granulate peripherally and more or less smooth centrally, weakly shining, with very fine sparse punctures. Foveate groove ( Fig. 65 View FIGURES 62–66 ) thin, curved, situated in centre of mesopleuron, not reaching neither its front nor hind margin, with short transverse wrinkles. Propodeum granulate, impunctate, dull. Propodeal spiracle separated from pleural carina by 1.0–2.0× diameter of spiracle ( Fig. 65 View FIGURES 62–66 ). Basal area of propodeum narrow, 0.5–0.8× as long as apical area, with basal longitudinal carinae subparallel or weakly divergent anteriorly (sometimes indistinct); transverse carina with short adjacent wrinkles; apical area flat, widely rounded anteriorly; apical longitudinal carinae complete or incomplete (reaching or not reaching transverse carina anteriorly).

Fore wing with second recurrent vein (2m-cu) distinctly postfurcal. Intercubitus (2rs-m) short and thick, shorter than abscissa of cubitus between intercubitus and second recurrent vein (abscissa of M between 2rs-m and 2m-cu). First abscissa of radius (Rs+2r) almost straight, 1.2× as long as 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, almost completely enclosing brachial cell posteriorly. Hind wing with nervellus (cu1&cu-a) slightly reclivous. Legs slender. Tarsal claws long, not pectinate.

First tergite 3.6× as long as posteriorly broad, in cross-section trapeziform centrally; in profile, with upper margin more or less evenly convex, sometimes with apical 0.3 somewhat stronger convex; postpetiole distinctly wider than petiole in dorsal view; first tergite mostly smooth, petiole partly with very shallow striae dorsally and laterally. Glymma deep, relatively large, situated in posterior 0.6 of tergite, joining by deep furrow to ventral part of postpetiole. Second tergite 1.4–1.5× as long as anteriorly broad. Thyridial depression sharp, about 1.5× as long as broad. Ovipositor weakly and evenly bent upwards, with shallow dorsal subapical depression ( Fig. 66 View FIGURES 62–66 ); sheath 1.8–2.2× as long as first tergite.

Head, mesosoma and first metasomal segment dark reddish brown to brownish black. Palpi, mandible (teeth red) and lower 0.4 of clypeus brownish yellow. Antenna brownish black, scape and pedicel ventrally yellow-brown. Tegula yellow. Wings hyaline. Pterostigma brown, with whitish markings in proximal and distal corners. Legs brownish yellow, hind coxa more or less darkened with brown. Metasoma posterior to first tergite brown ventrally to dark brown dorsally, sometimes with weak yellowish markings ventrally and on lateral sides.

Male. Unknown.

Etymology. The species is named after the Latin spectabilis (noteworthy, outstanding).

Distribution. Mexico (Tamaulipas).

Comparison. The new species differs from all other Mexican species of Probles by the combination of its robust antennae with short flagellomeres ( Fig. 63 View FIGURES 62–66 ), eyes with setae ( Fig. 64 View FIGURES 62–66 ) and short second tergite.
