Tobantilla andrikos Williams, Brothers & Pitts , sp. nov.

( Figs 15 , 19–22, 35 )

Diagnosis. MALE. The clypeus has a medial tubercle anteriorly ( Fig. 35 ), while the metasoma is entirely black except for the red T2 and S2 ( Fig. 15 ) and the legs are dark ferruginous and concolorous with the pleura.

Description. MALE. Body length 5.5–7 mm. Coloration. Head, mesosoma and metasoma black, except basal nine tenths of T2 and S2 red. Antennae, legs, medial portion of mandibles, and tegulae brown. Tibial spurs white. Wings weakly infuscated, veins brown. Head clothed with appressed silver setae, vertex with interspersed erect silver and brown setae. Mesosoma clothed with appressed silver setae, except medial half of mesoscutum and axilla clothed with black setae. Posterior half of T2 and metasomal segments 5–6 with interspersed black and silver setae; pygidium and hypopygium clothed with black setae, remainder of metasoma clothed with silver setae. Head. Rounded posteriorly, with slight posterior projection behind ocelli. Head width 1.1 × pronotal width. Eye transversely ovate, in dorsal view eye diameter 2.7 × distance from posterior eye margin to posterolateral angle of head. Ocelli small; ocellocular distance 4.0 × length of lateral ocellus, interocellar distance 1.2 × lateral ocellar length. Occipital carina weak but distinct, extending ventrally almost to level of oral fossa. Punctation on front and gena obscured by dense shaggy recumbent setae; vertex moderately punctate. Gena ecarinate. Antennal scrobe broadly concave to eye margin, with prominent complete flangelike transverse carina above. Clypeus having sharp anteromedial tubercle ( Fig. 35 ). Oral fossa 1.4 × length of hypostomal bridge. Scape bicarinate ventrally. Flagellomere 1 1.2 × pedicel length; flagellomere 2 2.0 × pedicel length. Mandible oblique, tapering, bidentate apically, unarmed ventrally. Maxilla and labium elongate. Maxillary palp 6-segmented, third and fourth segments slightly flattened and apically expanded, other segments almost cylindrical. Labial palp 4-segmented, second and third segments slightly flattened and apically expanded, other segments almost cylindrical. Mesosoma. Epaulets lowly produced; pronotum emarginate anteromedially. Pronotal dorsal punctation coarsely contiguous but obscured by dense shaggy recumbent mesally directed setae; anterior face densely punctate, except emarginated medial area glabrous; lateral face moderately punctate above but almost smooth ventrally. Tegula convex, glabrous except with long recumbent setae anterolaterally and posteromesally. Mesoscutal punctation coarsely reticulate, micropunctate inside reticulations; notaulus and parapsis indistinguishable; posterolateral corner forming a coarsely punctate raised lobe. Scutellum slightly convex, contiguously punctate. Axilla produced posteriorly, contiguously punctate on dorsal anterior half, glabrous on dorsal posterior half, posterior face truncate with posteriorly directed setae; anterolateral axillar margin contiguous with posterior mesonotal margin. Mesopleural punctation obscured by dense setae. Metapleuron glabrous with small scattered punctures. Propodeum strongly convex, entirely reticulate, except smooth and shining adjacent to metapleuron. Wings. Forewing with moderate ovate sclerotized pterostigma; marginal cell short and truncate apically; two submarginal cells. Legs. Mid- and hind tibiae each with a few strong spines dorsally, distinct apical secretory pore on inner surface near base of inner spur; spurs densely clothed with microsetae. Metasoma. T1 petiolate, 0.45 × width of T2, with moderately spaced coarse punctures. T2 moderately punctate; apex obscured by dense fringe of mesally directed setae; felt line 0.4 × lateral length of T2. T3–6 densely punctate. Pygidium margined laterally and posteriorly by a strong sharp carina; surface shallowly concave except medially raised, granulate with a few raised rugae. S1 with longitudinal carina in anterior half and contiguously punctate in posterior half. S2 moderately punctate, evenly convex. S3–6 moderately punctate. Hypopygium moderately punctate, posteromedial margin with sharp tooth. Genitalia ( Figs 19–22 ). Free length of paramere dorsally curved apically, with ventral brush of long dense setae basally, remainder having scattered short sparse setae; apex of ventral face not visible from above. Cuspis deeply divided near base, cylindrical, ~0.25 × free-length of paramere, posterior half having long dense posteriorly directed setae; densely setose basal lobe present. Digitus laterally compressed, constricted at apex, asetose, ~0.3 × free-length of paramere. Parapenial lobe well developed, apically angulate. Penis valve asetose, ventral margin bidentate apically, teeth separated.

FEMALE. Unknown.

Type material. Holotype, 3, COLOMBIA, Vichada, PNN Tuparro Bosque Sabana, 5°21'N 67°51'W, 100m, malaise, 22–31.I.2001, W. Villalba (IAvH). Paratypes, 23, same data as holotype (IAvH, EMUS).

Distribution. This species is known only from the type locality.

Host. Unknown.

Etymology. From the Greek andrikos “manly” named in honor of Donald G. Manley for his research on Mutillidae ; indeclinable.

Remarks. This species and T. krima are the first Tobantilla recorded from Colombia. Insects do not obey political boundaries, however, so there is no reason to assume that T. andrikos and T. krima are conspecific without a greater understanding of their geographic ranges. In fact, these species were collected in areas over 800 km apart ( Fig. 39 ).
