Head: White; fronto-orbital plate with golden pruinosity; vitta with almost the same width of parafrontal; 12-14 pairs of frontal setae, 1-2 pairs below the level of antennal insertion; frons with 0.25 of head width at the level of anterior ocellus; inner vertical setae crossed, outer verticals present; flagellomere brownish on outer surface and yellowish on inner; proboscis similar in length with head height; vibrissa long; 3-6 pairs of subvibrissal setulae; palpus similar in length with antenna and little swollen and curved upwards at tip.

Thorax: Scutum with golden pruinosity; acrostichals 2+1; dorsocentrals 2+3 or 3+3; intra-alars 1+3; post-pronotals 2; scutellum with one pair of basal setae; one pair of subapical setae and one pair of discal setae near apex; pleura covered with white pruinosity. Wing and calypter hyaline, vein R 1 setulose basally on dorsal surface and vein R 4+5 setulose from base almost to crossvein r-m on dorsal surface. Legs with coxa, trochanter and femur yellowish and tarsus brown; fore tibia with one anterodorsal row of short setae; 1 dorsal subapical seta; 1 posteroventral apical seta; mid femur with 1 anterior seta on middle third; 2-3 sparse posteroventral setae on basal half; 2 posterodorsal subapical setae; mid tibia with 1 strong anterodorsal and 1 strong ventral seta on middle third; 2 posterior setae on middle third; 1 anterodorsal subapical seta; 1 anteroventral, 1 ventral and 1 posteroventral apical seta; hind femur with 4-6 anteroventral setae on basal half and 1 seta on apical third; 4-6 posteroventral setae on basal half; hind tibia with one anterodorsal row of setae, the median one the largest; 3-4 ventral setae on middle third, the apicad the largest; 1 anterodorsal and 1 posteroventral subapical seta; 1 ventral apical seta.

Abdomen ( Fig. 29 ): Yellow; T 1+2 not excavate to its hind margin; T 3 and T 4 with median apical brown spots dorsally; T 5 shine yellow with brown spots laterally.

Male terminalia: Cerci large and not fusioned; surstylus shorter than cerci and with few sparse ventral setulae on the base; pregonite triangular in lateral view and postgonite narrow in lateral view.

Female: Unknown.

Type material: Holotype male. HONDURAS. Corocito , 03.iv.1924 [Curran Collection acc 31144] ( AMNH).

Other material examined: MEXICO. Morelos, Cuerna vaca, 1 male, x.1944, Krauss, N.H.L. col. ( USNM) . GUATEMALA. La Providencia, O bispo, 1 male, 16.iv.1926, Aldrich, J.M. col. ( USNM) .

Geographic distribution: Honduras, Mexico, Guatemala (last two, new records).

Comments: The species appears as Myobia (?) pellucens in Curran (1934) ’s key but a possible new combination is not formalized.
