Diagnosis. Female. The combination of the black propodeum and metasoma, completely white tibial spurs without black tips, apparently absent or inconspicuous felt lines, and the striated first and second metasomal terga separates T. tayronensis sp. nov. from any other known species of the genus. Male. Unknown.

Description. Female (holotype). Length 8 mm. Head, antennae, palps and pronotum reddish orange, mandibles reddish orange except for dark tip; front leg orange as above, femur darker apicad; tarsi yellowish brown; basitarsus of hind legs brown; tibial spurs white, without black tips. Remainder of integument uniformly black. Body with sparse black setae as follows: short black setae (shorter than pedicel length) on head front and pronotal dorsum, on each flagellomere, on scape arranged distally; in middle part of scape, a long seta perpendicular and projecting outwards; longer black setae (longer than pedicel length) on clypeal area, mesosoma and first metasomal segment; long erect black setae, marginally scattered on metasomal segments 3–6, denser on last two terga; short apical bands of appressed black setae on terga 4 and 5. White setae arranged as follows: long to very long setae, lengths greater than those of antennal segments 2 + 3 on anterior margin of clypeus projecting forward, and on external margin projecting outwards; adpressed white setae on first metasomal tergum, a black semicircle on the anterior part of segment; two bands of appressed white setae on distal margin of terga 2 and 3, the first about 1/5 of tergal length, the other about 1/2.

Head. 1.1 × as wide as pronotum, slightly wider than mesosoma; surface with fine, well-spaced punctures and reticulated; front between eyes 1.16 × maximum eye height; malar space large, 038 × maximum eye height; scape 2.1 × as long as pedicel; pedicel 0.71 × as long as first flagellar segment; first flagellar segment 0.86 × as long as second. Maxillary palp 6-segmented, the second segment widest; labial palp 4-segmented.

Mesosoma. Pronotum length, including anterior flange, 0.96 × pronotal width, widest at shoulders, lateral margins slightly converging posteriorly. Pronotal dorsum with irregular longitudinal striae. About ¾ of inferior pronotal sides with oblique irregular striae, otherwise smooth and with feebly punctate. Mesonotum very short, hidden by setae from bordering segments. mesopleuron with oblique striae finely punctate, covered with thin, semierect, sparse setae. Fused metanotum-propodeum with longitudinal irregular stria, dorsally grossly punctate, laterally with conspicuous longitudinal oblique striae, almost impunctate. Metasternal plate weakly punctate, apex rounded, without distinct median keel.

Legs. Underside of fore tibia with appressed silvery pubescence. Mid and hind coxae, femora and tibiae with appressed silvery pubescence. Mid and hind femora with long erect setae, as long as maximum femoral width or longer, more abundant ventrally and whitish in color. Hind coxa apparently unarmed. Longer tibial spur of hind tibia 0.61 × as long as hind basitarsus. Tibial spurs count 1–2–2, mid and hind tibial spurs white without dark tips. Claws dentate, although each tooth very small, visible only under high magnification (80× or more).

Metasoma. First tergum with anterior third a subtriangular neck with upper surface almost flat, posterior two-thirds gibbose, shallow constriction between neck and gibbose posterior part; 1.37 × as broad as long (measured dorsally). First and second terga with longitudinal striae, and a strong constriction between these terga. Second tergum with scattered dark appressed setae. Lateral felt line apparently absent or very inconspicuous. Second tergum 1.21 × as long as first.

Male. Unknown.

Distribution. Colombia: Magdalena.

Etymology. The name refers to the Tayrona National Natural Park and the indigenous ethnic group of the same name, ancient and current inhabitants of the region. It is an adjective.
