(Figures 23–26, 30)
Centris vittata Lepeletier, 1841: 168.
Centris nigrescens Lepeletier, 1841: 166, 167 (synonymized by Moure et al., 2007).
Centris montezuma Cresson, 1879: 213 (synonymized by Michener, 1954).
Centris breviceps Friese, 1899: 44 (synonymized by Ducke, 1916).
Centris friesei Crawford, 1906: 158, 159 (junior primary homonym of C. (Melanocentris) furcata friesei Schrottky, 1902 and Centris friesei Ducke, 1902) (Moure et al., 2007).
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).
Morphology. Female (Figs. 23, 24). Measurements: Approximate body length: 22.3; head width: 6.7; thorax width: 7.1; forewing length: 16.4; UID: 3.0; LID: 3.2; mandible length: 2.2; basal mandibular width: 1.0; labrum length: 1.0; labrum width: 1.8; F1 length: 1.1; F2 length: 0.3; F3 length: 0.4; scape length: 0.7; diameter of median ocellus: 0.4; distance between lateral ocellus and eye: 0.7. Coloration: Head and mesosoma dark brown. Legs and metasoma brown reddish. Lower paraocular area, mandible and base of fore and middle tibiae yellow. Clypeus with transversal yellow band. 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. Clypeus and labrum with light orange to yellow hairs. Gena with yellow to whitish pubescence. Ventral surface of mesepisternum and fore leg with yellowish light brown hairs. 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.
