Loyugesa khuati (after Grimaldi & Blagoderov, 2001)
Body coloration an even dusky brown, no banding on legs or tergites.
Head: Shape nearly spherical in lateral view; eyes very large, holoptic for approximately 0.6× length of frons between ocelli and antennal bases. Eyes greenish, with dense pilosity; interfacetal setulae slightly longer than facet diameter. No dorso-ventral differentiation of facets. Median ocellus lost (difficult to discern if frons very sunken); vertex velvety black; ocelli whitish, on tubercle. Frons between antennal bases and where eyes meet medially is mostly membranous, but with very narrow, velvety ridge of cuticle in center. Antenna: scape about same size as flagellomeres; pedicel 2× size of scape, with single dorsal seta; 12 flagellomeres present, flagellomeres moniliform, decreasing slightly in width apicad; length of flagellum slightly less than depth of head. Clypeus a small setose mound on face; face largely membranous, narrow, bounded laterally by margins of eyes. Labrum small, narrow, triangular (length approximately 2× the width), apically pointed and length 0.3× that of palps. Length of proboscis approximately equal to depth of head, longest portion is pair of labella; median hypopharynx slightly shorter, with serrate tip. Hypopharynx diaphanous, delicate. Palps relatively short, c. 0.4× length of labella, with row of lateral setae along most of its length. Postgena membranous.
Thorax: Scutum dome-shaped, with median row of acrostichal setae extended from anterior margin to half the length of scutum; 2 paramedian rows of dorsocentrals extending nearly the length of scutum, dorsocentrals same size as acrostichals. Scutellum short, with marginal setae; median ones longest, lateral ones shortest. 7-8 notopleural and supra-alar setae. Pleura in lateral view as figured (fig. 4). Ventral margin of katepisternum rounded. Anterior margin of thorax slightly anterior to or at same level as fore coxa. Episternite with only 2 setae. Pleura bare, including laterotergite. Laterotergite not flat nor distended from pleural wall. Metanepisternum cleft, posterior lobe not reaching to ventral margin of laterotergite.
Legs: Mid coxa short, apex not reaching to apical level of hind coxa; hind coxa without depression on anterior end. All coxae with sparse setae. Legs of moderate length. Tibial spurs 0-1-2. Base of hind femur whitish. Hind tibia clavate, apical width 3× proximal width, apical third with longer, dense setae. Hind tibial spurs microtrichose, unequal in length; inner spur 2.5× size of outer one. Hind basitarsomere large: width equal to apical width of tibia, length equals combined lengths of distal tarsomeres. Hind tarsomeres decreased in width apicad.
Wing: Length approximately equal to length of abdomen; color fuscous, slightly darker apically. Apical margin very rounded. Sc incomplete; h not oblique; R1 very short, length ca. 0.25x length of wing. R4+5 entirely bare. C ends midway between apices of R4+5 and M1. Rs vestigial, incomplete. Base of R with acute angle and pinched; R4+5 with base incomplete, vein completely bare even at apex. Only apical third of veins M1 and M2 present (bases lost), length of M2 is 1.3x length of M1. CuA1 and CuA2 forked (sessile), with stem ca. 2.5x length of fork. CuP very close and parallel to stem of CuA. Very tiny cup and a cells at base of wing. No trace of vein A; anal lobe well developed. Halter white.
Abdomen: Tergites and sternites II-IV longest, decrease in length posteriad. Segment I small. Male genitalia with t IX relatively large, oval, with sparse apical spicules; gonocoxae stout; gonostyli very stout, length 2.3× the width. Apex of gonostylus with dense spicules, apical tooth not observed.
Measurements (means): body length 2.21 mm; thorax length 0.50 mm; wing length 1.50 mm.
