Etymology

The species epithet qibos is an anagram of bosqi , thereby stressing the similarity and possible sister­group relationship between the present species and Engelimyia bosqi . The name should be treated as a noun in aposition.

Description of adult male

Like E. bosqi but differing by the following: Head: Frontal row of 9–11 bristles; outer vertical bristle not differentiated from postocular setae and about 0.25 x as long as inner vertical bristle; arista long plumose in basal 0.65. Thorax: Meropleurals 8–10; mid femur with a row of 3–4 median anterior bristles and 1–2 median anteroventral. Abdomen: ST5 with median part not or very slightly raised, outline of posterior half almost triangular but rounded posteriorly ( Fig. 35 ). Anterior margin almost straight, postero­lateral lobes rounded and not particularly broad ( Fig. 36 ). Terminalia: Cercus with distinct subapical dorsal hump and the tip bent at about 45 degrees relative to the longitudinal axis; with long setae on mid lateral margin ( Fig. 33 ). Dorsal margin gently sinuous. Cerci in posterior view symmetrical and with a median common projection. Surstylus with strongly sinuous anterior (or ventral) margin so as to appear restricted in the middle ( Fig. 34 ). Pregonite broad at base, with a strongly sinuous basal margin, about as long as postgonite, and distal half perpendicular to basal half. Postgonite with gently curved tip, a strong median bristle on anterior margin and a smaller one just distal to this ( Fig. 37 ). Phallic tube with a median, tapering projection of the anterior (or ventral) margin; juxta shaped as a pair of long, curving posterior apophyses reaching almost to the tip of the membranous apical structure, which is restricted at base and with entire surface spinose; vesica with spinose surface, almost quadrate in lateral view but with anterior surface sinuous; lateral styli with base only slightly expanded ( Figs 38 , 42 ).

Distribution

Neotropical—Costa Rica.
