Female.

Body size: 3.0-3.5 mm. Color: body dark brown, metasomal terga 2 medially and terga 5-7 yellow; scape yellow with lateral longitudinal brown stripe, flagellum brown with apical whiter annulus, apical 5-7 flagellomeres brown; wing veins including stigma brown; legs yellow, apical half of fore and middle femora and apical ⅓ of hind femur brown. Head: vertex granulate; frons granulate; face granulate; temple in dorsal view narrow, sloping behind eye, width less than 1/2 eye width; malar space equal to or slightly greater than 1/4 eye height; ocell-ocular distance about 2.5 times diameter of lateral ocellus; 22-25 flagellomeres. Mesosoma: mesoscutal lobes granulate; notauli weakly scrobiculate or partially smooth, meeting at scutellum in triangular costate area; scutellum granulate; prescutellar furrow with 3-5 cross carinae; mesopleuron granulate; precoxal sulcus scrobiculate, shorter than mesopleuron; venter granulate; propodeum with basal median areas distinct but not margined, granulate, basal median carina absent, areola not margined, areolar area rugose, lateral areas entirely rugose, propodeum with distinct tubercle above hind coxa. Wings: fore wing vein r shorter than vein 3RSa, vein 1cu-a interstitial with or very slightly beyond vein 1M; hind wing vein SC+R absent, vein M+CU shorter than vein 1M. Metasoma: first tergum longitudinally costate often granulate medially, length greater than apical width; second tergum longitudinally costate, lateral costae distinctly angled toward mid-line; anterior transverse groove present, straight; posterior transverse groove present; third tergum entirely smooth except for costate transverse groove; terga 4-7 smooth; ovipositor equal to length of metasomal tergum 1.

Comments.

The second metasomal tergum with lateral costae angled toward mid-line, the short ovipositor and bicolored flagellum are distinctive for this species.

Etymology.

Named for Vulcan, the Roman god of fire, in reference to most of the type series being collected at Volcan Cacao.
