( Figs 1 View FIGURE 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 View FIGURE 1 F); clypeus apically with margin convex; mesopleuron centrally smooth; metapleuron smooth, without striae ( Fig. 5 View FIGURE 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 View FIGURE 4 B); fore wing with a black spot at distal 0.3 of marginal cell and distal half of submarginal cell ( Fig. 1 View FIGURE 1 F); tergite I, orange brown ( Fig. 5 View FIGURE 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 View FIGURE 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 View FIGURE 5 B); propodeum ( Figs 4 View FIGURE 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 View FIGURE 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 View FIGURE 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 View 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 View FIGURE 5 D). Area spiracularis and lateralis strongly punctate ( Fig. 5 View FIGURE 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 View FIGURE 4 B).

L. schausi . Tergite I yellow basally and distally, orange medially, with a dorsal longitudinal black stripe ( Figs 5 View FIGURE 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 View FIGURE 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.
