Cathyalia Ragonot, 1888: 7; Roesler & Küppers, 1981: 15; Roesler, 1983: 78; Robinson, Tuck & Shaffer, 1994: 159; Shaffer, Nielsen & Horak, 1996: 177. Type species: Cathyalia fulvella Ragonot, 1888.
General characters. Vertex flat, with rough scales. Antenna simple and shortly pubescent on both sexes. Ocellus present. Chaetosema well developed. Labial palpus upturned beyond head, with third segment slightly shorter than second, apex pointed. Maxillary palpus short, no longer than second segment of labial palpus. Proboscis well developed. Forewing with R 2 and R 3+4 +R 5 close at base or shortly stalked, R 3+4 and R 5 stalked for about half length of R 5, M 2 close to M 3 at base, from lower angle of cell, CuA 1 and CuA 2 free; cell about 2/3 length of forewing. Hindwing with Rs and Sc+R 1 long-stalked, M 1 and Sc+Rs+R 1 stalked for 2/5 of M 1, M 2 and M 3 close at base, from lower angle of cell, CuA 1 and CuA 2 free; cell very short, only 1/5 length of hindwing.
Male genitalia. Uncus bell-shaped. Apical process of gnathos small, triangular or clubbed, with a small hook distally. Transtilla fused, usually a narrow arched band. Valva with clasper; costa and sacculus strongly sclerotized, extended to end of valva. Vinculum U-shaped, longer than width. Juxta usually U-shaped, lateral lobes various in shape, globular or finger like, or fused and extremely extended to middle of uncus. Aedeagus slender, with one sinuate sclerite; cornuti a cluster of spines or thorns. Culcita present.
Female genitalia. Anal papillae triangular. Eighth abdominal segment short and wide, collar-shaped. Apophyses anteriores and posteriores short, nearly equal in length. Antrum rectangular. Ductus bursae mostly sclerotized. Corpus bursae membranous, elongate elliptic. Signa usually comprised of a transverse row of flag-shaped or conical spines. Ductus seminalis incepted at junction of ductus bursae and corpus bursae.
Distribution. China, Japan, Thailand, Malaysia, Indonesia, Brunei, India, Sri Lanka, Australia, Papua New Guinea.
Key to Chinese Cathyalia species (based on male genitalia).
1. Forewing with a broad white streak from basal 1/5 to apex along costa (Figs 1, 5); transtilla without process, clasper simple in the male genitalia; ostium at intersegmental membrane between seventh and eighth segments, ductus bursae without thorn in female genitalia ............................................................................................................................................................................................ 2
Forewing without broad white streak along costa (Fig. 3); transtilla with three short processes on posterior margin, clasper complex in the male genitalia (Fig. 8); ostium at center of seventh segment, ductus bursae with two sharp thorns posterolaterally in female genitalia (Fig. 11) ................................................................................................................................................................ C. fulvella
2. Labial palpus with terminal two segments about equal length (Fig. 1a); apical process of gnathos small triangular, juxta with lateral lobes fused and extremely extended to middle of uncus in male genitalia (Fig. 7); ductus bursae about half length of corpus bursae, strongly sclerotized except with a narrow membranous ring at 1/3, corpus bursae not scobinate in female genitalia (Fig. 10) ........... .......................................................................................................................................................................................
