(Figs 1 F, 4B, 5B, 5D, 8)
Diagnosis. Labena madoricola can be distinguished from all New world species by the following characters in combination: antenna in dorsal view entirely black or blackish brown (Fig. 1 F); clypeus apically with margin convex; mesopleuron centrally smooth; metapleuron smooth, without striae (Fig. 5 B); pleural carina entirely absent below spiracle; area superomedia hexagonal, clearly delineated, very large, 1.15–1.63 × as broad as long; area basalis quadrangular, relatively large, elongated, about 0.9 × as broad as long (Fig. 4 B); fore wing with a black spot at distal 0.3 of marginal cell and distal half of submarginal cell (Fig. 1 F); tergite I, orange brown (Fig. 5 D); first sternite without a central transverse ridge; tergites III–IV with posterior margin straight not exposing membrane. Mesosoma dorsally, hind leg and metasoma entirely orange (Fig. 1 F).
Description. Male. Body length 13 mm. Fore wing length 9 mm.
Head. In dorsal view 1.7–1.8 × as wide as long; clypeus in anterior view, basally flat, with a broad shallow impression either side of slightly convex central apical region, with apical margin centrally strongly convex; 1.47– 1.60 × as broad as high; clypeo-facial suture and central apical region with scattered and long setae; malar space 0.2–0.3 × as long as basal width of mandible; frons flat, shiny, with fine punctures; vertex and gena smooth and shiny with very fine setiferous punctures; gena, in dorsal view, rounded and weakly constricted behind eyes, about 0.31–0.43 × as long as eye; lower part of gena moderately broad; interocellar area elevated; posterior ocellus separated from eye by 1.20–1.40 × its own maximum diameter; distance between posterior ocelli 1.20–1.25 × maximum diameter of posterior ocellus; occipital carina complete, reaching hypostomal carina far from base of mandible at same distance of width of mandible base; hypostomal carina from base of mandible to the union with occipital carina moderately raised; antenna with 47–49 elongated flagellomeres, except the apical one which is subtriangular with apex truncate, bearing a small flat sensillum.
Mesosoma. Pronotum smooth and shiny dorsally, upper lateral corner with dense fine setiferous punctures, lower part glabrous, in dorsal view with two lateromedian pits centrally; epomia absent; mesoscutum finely and densely punctate, with notauli absent, with a very short and weak transverse crest at anterior end; scutellum densely punctate, slightly convex, without lateral carinae; Mesopleuron smooth and shiny, upper anterior corner with fine and moderately dense punctures; upper end of epicnemial carina curved towards anterior margin slightly below the centre of hind margin of pronotum; Metapleuron entirely smooth and shiny (Fig. 5 B); propodeum (Figs 4 B, 5B) smooth and shiny, almost glabrous dorsally, laterally densely and conspicuously setose, setae moderately long; pleural carina absent anteriorly so that area spiracularis is open externally, present posteriorly and enclosing area lateralis; area spiracularis and lateralis strongly punctate; area lateralis as long as broad, ventrally slightly shorter than dorsally; area superomedia hexagonal, clearly delineated, very large, 1.15–1.63 × as broad as long; area basalis quadrangular, about 0.9 as broad as long; area dentipara, area posteroexterna and area petiolaris separated by weak carinae; lateral longitudinal carina complete, area externa strongly elongated, fully enclosed, 0.67–0.82 × as broad as long. Mid leg with tibia not inflated, with scattered slender bristles on outer surface, second tarsomere 6.67–8.0 × as long as broad and about same length of the following two tarsomeres; hind coxa about 4.67–5.43 × as long as deep; hind tibia with scattered bristles. Fore wing with areolet transverse, 0.33–0.44 × as broad as length of distal abscissa of M, with 3rs-m subequal to 2rs-m; vein Cu-a opposite to vein Rs & M or slightly basad; abscissa of Cu 1 between 1 m-cu and Cu 1 a slightly longer as Cu 1 b. Hind wing with vein Cu-a longer than abscissa of M+Cu between M and Cu 1.
Metasoma. Tergite I, 3.21–3.58 × as long as posteriorly broad, without lateromedian and lateral carinae (Fig. 5 D); sternite I reaching 0.5 of length of tergite, without a central transverse ridge; tergite II, 1.78–2.0 × as long as posteriorly broad, with fine and moderately dense pubescence; tergites III–IV with posterior margin straight not exposing membrane.
Coloration (Fig. 1 F). Yellow ventrally, tending to be gradually orange dorsally. Flagellum black above, somewhat lighter ventrally. Scutoscutellar groove black. Sometimes three longitudinal weak marks on mesoscutum and/or anterior rim of mesopleuron and /or peripheries of mesoscutum, darker. Wings hyaline; fore wing with a black spot at distal 0.3 of marginal cell and distal half of submarginal cell.
Female. Unknown.
Etymology. From Latin " mador" = moisture, wetness; " cola " = dweller, inhabitant. The name refers to the flooded savannah where the species was collected.
Phenology. Figure 8.
Taxonomic remarks. In comparison with the other Mexican species, L. madoricola is very close to L schausi but can be distinguished from it by the following characters in combination:
L. madoricola. Tergite I, orange brown (Fig. 5 D). Area spiracularis and lateralis strongly punctate (Fig. 5 B); area superomedia hexagonal, clearly delineated, very large, 1.15–1.63 × as broad as long; area basalis quadrangular, elongated, about 0.9 × as broad as long; area externa conspicuously longer than broad (Fig. 4 B).
L. schausi. Tergite I yellow basally and distally, orange medially, with a dorsal longitudinal black stripe (Figs 5 E-F). Area superomedia delineated anteriorly, though often rather weakly so laterally, subquadrate and quite large; area basalis transverse or subquadrate; area externa about as broad as long, subquadrate or shortly longer than broad (Figs 4 C-D).
This species can be distinguished from the species with unknown males, L. acerba, L. lachryma, L. morda, L. osai, L. pluvia, L. polemica and L. striata among other characters by the structure of propodeum.
