description: Fibuloides khaoyai Pinkaew and Zhang, n. sp.
(Figs. 1 C–D, 3B, 4B)
Diagnosis. This species is most similar to F. vaneeae Pinkaew in forewing pattern, but differs in the shape of the uncus and cucullus. The broad, scoop-shaped uncus and the nearly rhomboid-shaped cucullus of F. khaoyai contrast with the slender, deeply bifid uncus and the long and narrow cucullus of F. vaneeae.
Description. Head: Upper frons brown mixed with dark brown laterally, lower frons yellowish white; labial palpus with first segment orange white with dark brown spot apically, second segment orange white with dark brown spots basally and apicodorsally, with transverse dark brown band medially, apical segment small, orange white; vertex brown mixed with dark brown laterally.
Thorax: Pronotal collar brown; tegula brown mixed with dark brown on basal 1/3; mesonotum brown mixed with dark brown. Forewing (Fig. 1 C–D) length 5.6 mm in male (n=1), 6.8 mm in female (n=1); male costal fold absent; ground color orange white mixed with brownish gray; costal strigulae orange white, strigulae 1–2 indistinct, 3–9 paired and separated by dark brown; termen with orange white strigula between R5 and M1, and dark brown narrow line from R5 to CuA1; basal fascia indistinct, with dark brown spot divided by orange white scales between costa and R and irregular rows of dark brown between R and inner margin; subbasal fascia distinct on costa between strigulae 2 and 3 and extending to near middle of discal cell, dislocated apically between middle of discal cell and inner margin, brownish orange mixed with grayish orange, margined by dark brown; median fascia extending obliquely from costa between strigulae 4 and 5 to R5, widened at R5 and extending transversely to 1A+2A, dark brown mixed with orange, broken by ground color at M-stem in discal cell; pretornal with a subtriangular spot, dark brown mixed with orange surrounded by dark brown on proximal and distal margins; postmedian fascia extending obliquely from costa between strigulae 6 and 7 to R5 near outer margin, brown to dark brown mixed with orange, strigulae 5 and 6 with silvery striae becoming confluent extending obliquely to R5, strigulae 7 with silvery striae extending obliquely to R5, strigulae 8 and 9 with short silvery striae, outer margin with silvery striae extending from M2 to CuA2; ocellar region with dark brown patch between R5 and CuA1. Underside light brown with yellowish gray striae on costa and on termen. Hindwing brown dorsally, light brown ventrally.
Abdomen: Male genitalia (Fig. 3 B) with tegumen narrow basally, gradually broader to top, parallel-sided in basal half, dorsally rounded, with sparse setae. Uncus broad, short and flat, blunt apices, bending outwardly. Socii slender, apically rounded, originating from base of uncus, pendant to 1/4 of tegumen length, moderately setose. Gnathos arising from about half of tegumen, weakly sclerotized. Valva with relatively small basal excavation, ventral margin concave between sacculus and cucullus and produced into slender curved neck; sacculus sparsely setose basally, with enlarged flattened bristles on sacculus angle; neck with dense hairs; cucullus nearly rhomboidshaped, with hairs and slender spines, round dorsally and with a small triangular salient, nearly right-angled ventrally. Anellus closely surrounding basal 2/5 of phallus; phallus moderately long, only slightly curve at distal 1/3, with several deciduous cornuti; juxta triangular, truncate ventrally. Female genitalia (Fig. 4 B) with papillae anales densely setose; apophyses posteriores slightly shorter than apophyses anteriores. Sternum VII densely scaled especially on posterior margin except anteromedially half, anterolaterally with patch of densely microtrichiate, posterior margin of sternum VII slightly concaved medially, membrane between sternum VII and VIII with dense microtrichia. Ostium bursae located on posterior margin of sternum VII. Antrum sclerotized forming a large cupshaped. Ductus bursae moderately long with large sclerotized plate slightly extending into corpus bursae, inner surface with group of moderately dense spinulose medially; ductus seminalis arising from nearly anterior end of ductus bursae. Corpus bursae ovate, narrower at anterior 1/4, spinulose except anterior end and area around signa; two blade-shaped signa, widest beyond middle and tapering to sharp point.
