( Figs. 14 View FIGURES 9 – 14 , 28 View FIGURES 23 – 28 , 38 View FIGURES 34 – 39 )

Diagnosis. Thylacogaster garcinivora is superficially similar to other species in the genus. The male genitalia are similar to those of T. rhodomenia and T. monospora with an elongate-rectangular tegumen, socii in the form of an expanded patch of fine setae from a membranous region subdorsally on the tegumen, simple valvae with a conspicuous distal spine, and a mesally expanded phallus. Thylacogaster rhodomenia has a rounded-triangular, densely bristled fold of the valva near mid-costa and a blunt spine along the venter of the valva ca. 0.6 the distance from the base to the apex that are absent in T. garcinivora ; and T. monospora has a dorsally-projecting spine subapically from the costa of the valva that is absent in T. garcinivora .

Description. Male. Head: Vertex and frons dark brown mixed with dark gray; labial palpus upcurved, mostly grayish white with white ventral scales, length ca. 1.3 times horizontal diameter of compound eye. Thorax: Notum dark grayish brown; venter mostly pale beige; tegula long, scales grayish brown with yellow tips; hindtibia with conspicuous, expanded patch of grayish white secondary scales. Forewing length 7.0– 7.8 mm (mean = 7.5; n = 5); costal fold absent; forewing oblong-subovate, costa gently curved throughout; apex broadly rounded, confluent with costal 0.5 of termen, basal 0.5 of termen convexly rounded, forming a distinct notch near mid-termen at junction of rounded halves; ground color dark gray brown, with many scales tipped with yellow, especially in tornal region; three faint, slender, oblique, iridescent leaden gray lines from costa toward termen, each bordered by one or two rows of yellow-orange scales; speculum mostly yellow orange with a single black spot; fringe bronze brown, somewhat iridescent in costal 0.5. Hindwing uniform brown; fringe much lighter. Abdomen: Genitalia ( Fig. 28 View FIGURES 23 – 28 ) with tegumen broadly rectangular; socius represented by moderately dense patch of hairs subdorsally from tegumen; valva large, oblong, costa and venter slightly undulate, falcate distally with a conspicuous stout spine at apex; cucullus occupying distal 0.3 of valva, with long setae directed inward toward tegumen; phallus long, ca. 0.5 length of valva, bulbous in middle, slender, strongly curved in distal 0.6, broader, less curved in basal 0.2; cornuti not apparent in vesica.

Female. Head and thorax: Essentially as described for male; forewing length 7.0–8.0 mm (mean = 7.5; n = 10), frenulum usually with three bristles, rarely with two or four. Abdomen: Genitalia ( Fig. 38 View FIGURES 34 – 39 ) with ovipositor somewhat telescopic; papillae anales slender; apophyses slender, slightly dilated at anterior tips, posteriores ca. 1.2 as long as anteriores; ostium bursae within simple, shallow cup; lamella postvaginalis faintly punctate with a small group of short bristles on each posterolateral corner distad of ostium bursae; colliculum absent; ductus bursae very narrow, ductus seminalis originating approximately mid-length of ductus bursae; corpus bursae round, faintly and evenly dimpled; two horn-shaped signa, each from a rounded basal plate.
