Centris costaricensis Crawford, 1907: 21 (nom. nov. for Centris friesei Crawford, 1906 ) ( Moure et al., 2007).

Diagnosis. Both sexes with yellowish hairs with black tips on mesoscutum and mesoscutellum and concave clypeal disc. Because of the pubescence (yellow hairs with dark brown to black tips) on dorsal surface of mesosoma, this species is similar to C. dichrootricha , differing from it by the clypeal disc that is almost smooth, with very scattered punctures in the female, more densely punctate in the male (distance between the punctures greater than the diameter of the punctures) (clypeal disc areolate and flat in C. dichrootricha ). Males can be distinguished by the uniformly curved inner spur of the hind tibiae and by the orange brown metasoma with orange and yellowish pubescence in C. vittata (spur apically curved and metasoma dark brown, except on T6, T7 and distal half of T5 orange, with dark brown pubescence in C. dichrootricha ).

Labrum yellow with triangular dark brown spot on upper half. Anterior surface of F3–F9 light brown. Tegula dark brown with posterior half yellowish. Wings membrane and veins dark brown. Sculpture: Clypeus shiny with sparse, moderately dense punctation. Labrum with coarse and dense punctures. All terga with fine and dense punctation, sparser on distal terga. Pubescence: Head (except clypeus, labrum and gena), mesoscutum, mesoscutellum, lateral surface of mesepisternum, tegula and dorsal surface of T1 with yellow hairs with dark brown to black tips.

Middle and hind legs with light brown pubescence. T2–T4 with brown and short hairs. T5, T6 and, fimbriae with light brown, relatively long pubescence. Structures: Mandible with three teeth (1st>3rd>2nd) with acute apex, except third truncate. Second tooth very small, almost fused with rutellum. Trimal angle acute, well-developed. Acetabular carina reaching base of third tooth. Clypeal disc strongly concave (lateral view). Labrum sub-rectangular with rounded edges. Inner orbits of compound eyes diverging above. Vertex slightly above upper ocular tangent. Secondary anterior comb of fore elaiospathe formed by three giant apically curved hairs. Pretarsal claws with small preapical tooth, absent in hind leg.
