Cymosema capelina Burks & Mottern sp. n. Figs 15-20

Etymology.

Noun from Spanish, meaning wide-brimmed floppy hat, referring to the head shape.

Diagnosis.

Mandibles highly reduced, broader than long and truncate. Funiculars tapering to apex. Frons smooth. Submarginal vein with several long setae, fore wing with distinct marginal fringe.

Female.

Length 1.3 mm. Head and mesosoma dark brown with very faint metallic luster. Scape, pedicel and anellus pale brown, funiculars and clava brown. Leg brown to milky brown, with slightly darker areas on the coxa basally, femur except at its tips, tibia subbasally, and last two tarsomeres. Fore wing hyaline; venation pale brown, setae dark. Gaster brown with faint metallic luster.

Head (Figs 16-17 ) transverse, 1.4 × as broad as high. Head receding ventral to toruli (Fig. 18 ); face dorsally smooth, ventrally coriaceous; supraclypeal area and clypeus medially smooth and laterally shallowly coriaceous, anteclypeus absent; vertex not carinate. Mandibles truncate and broader than long, broadly separated. Palpal formula 2:1, palpi long. Pedicel broader than F2; anellus small but easily visible; flagellum 1.4 × head height, with 7 funiculars that expand apically and have semi-erect long setae arising from their bases; F2 1.3 × as long as broad, 1.0 × as long as F3.

Mesosoma (Figs 18-19 ). Mesoscutum smooth and glossy, notauli evenly impressed and smooth. Axilla strongly advanced, smooth; scutoscutellar suture finely foveate; mesoscutellar disc and axillula smooth, without axillular sulcus; frenum distinguished by a slight change in elevation at frenal line, smooth. Propodeal disc with median carina, weakly sculptured laterally; callus bare, separated from propodeal disc by wrinkle-like longitudinal carinae. Metacoxa smooth to shallowly reticulate. Fore wing spatulate, 2.6 × as long as broad; costal cell with 1 complete row of ventral setae; submarginal vein with several long hairs; basal cell setose dorsally and ventrally; speculum absent; cubital and subcubital folds setose; marginal fringe present; stigmal vein 1.5 × as long as broad; dorsal setae of disc much longer than ventral setae; postmarginal vein about 1.5 × as long as stigmal vein. Hind wing costal cell with a few setae in apical third.

Metasoma. Petiole 0.7 × as long as metacoxa, 1.8 × as long as broad, smooth except for longitudinal carinae, including a median carina dorsally, narrowing anteriorly to abruptly expand at the anterior condyle, without anterior transverse carina, ventrally smooth (Fig. 20 ). Antecostal sulcus of Gs1 crossed by many longitudinal carinae; acrosternite smooth. Cercus with all setae subequal in length. Hypopygium bare. Ovipositor only slightly exerted in holotype and features not distinguished.

Male.
