Diagnosis. Head, including antennal flagellum, and mesosoma dark brown to black (Fig. 18), legs with coxae, trochanters and femora dark brown, tibiae and tarsi yellowish-brown (Fig. 17), fore wing infumate with part below stigmal vein dark brown (Figs 17, 18), Gt 1 yellowish-brown, Gt 2–7 dark brown (Fig. 18); antenna with F2–4 (excluding apical stalk) about as long as wide with a short stalk in anterior part (Fig. 17); pronotal collar with a carina along anterior margin (Fig. 18); midlobe of mesoscutum with three pairs of long and strong setae (Fig. 18); mesoscutellum with sublateral grooves joining in posterior part (Fig. 18); propodeum smooth (Fig. 18).
Description (male holotype). Length 1.5mm. Frons and vertex with weak reticulation. Pronotal collar with a carina along anterior margin. Mesoscutum and mesoscutellum with weak reticulation; midlobe of mesoscutum with three pairs of long and strong setae; mesoscutellum with sublateral grooves joining in posterior part. Dorsellum and propodeum smooth; propodeal callus with six setae. Fore wing with six setae on dorsal surface of submarginal vein; with 12 admarginal setae; costal cell with a row of seven setae on ventral surface, apico-dorsal margin with three setae. Gaster short ovate.
Colour. Head dark brown to black. Antennae dark brown. Mesosoma dark brown to black. Legs with coxae, trochanters and femora dark brown, tibiae and tarsi yellowish-brown. Fore wing infumate with part below stigmal vein dark brown. Petiole black. Gaster with Gt 1 yellowish-brown, Gt 2–7 dark brown.

Gaster: length 47; width 27; Gt 1 length 24.
Variation in paratypes. Length 1.1–1.7mm. Scape pale brown to dark brown. Hind tibia and tarsus yellowishbrown to dark brown. Otherwise as in holotype.
Female. Unknown.
Remarks. The sharp carina along anterior margin of the pronotal collar is a distinctive feature for this species. Two other species, D. albicoxa and D. cristata, described from females (males unknown) also have this feature. Specimens of both these species are predominantly yellowish-brown, while specimens of D. carinifer are dark brown to black. While the colour of head and mesosoma might differ between the sexes of the same species (see D. pilosa) and are thus unreliable characters when associating conspecific females and males, the dark areas in the fore wing are similar in both sexes. Diglyphomorphomyia albicoxa and D. cristata both have two distinct dark brown areas in the fore wing, one below marginal vein and one below stigmal vein (Figs 3, 7), while D. carinifer has only part below stigmal vein dark (Fig. 17). Thus D. carinifer is not conspecific with either D. albicoxa or D. cristata.
Distribution. Costa Rica, Honduras.
Etymology. From the Latin carina = keel, and the suffix – fer = carry, referring to the pronotal carina.
