Lannapsyche chantaramongkolae Malicky 1989: 36 , 15–16, figs. 14a–14h. Type locality: Thailand

New record. PR CHINA: Yun-nan Province , Ma-li-po County , Nan-wen-he Village , Lao-jun-shan National Forest Preserve, N23°12’, E104°33’, alt. 1350 m, light trap, 13-vii-1990, Coll. Li Y-w. and Ke X., 1 male ( NJAU) ; 1 male (CUAC, Odontoceridae #010).

Our specimens are closely congruent with the description and illustrations of Lannapsyche chantaramongkolae provided by Malicky (1989). For clear comparisons, the wing venation and male genitalia are re-illustrated and redescribed.

Redescription. Adult. Length of each male forewing 8.8 mm (n = 1). Specimen in alcohol generally yellowish brown, forewings light brown. Forewings ( Fig. 5 Fa) each with R1 confluent with R2 shortly before apex, tips of R1+2, R3, and R4 equidistant, arranged regularly; forks I, II, III, and V present; forks I, II, and V sessile, fork III petiolate; single anal vein with dense row of bristles ventrally. Hind wings ( Fig. 5 Fp) each with R1 confluent with R2 beyond tip of Sc; bases of R5 and MA confluent so that crossvein r-m between R5 and MA absent.

Male genitalia. Pleura IX each divided by longitudinal horizontal groove into two parts, dorsal part slightly taller than ventral part in lateral view; anterior margins of segment IX roundly produced forward and lateromedian apical lobe of IX at posterior end of longitudinal groove angled about 70°, blunt ( Fig. 5A ). Tergum IX produced posteromesad into short and blunt triangular lobe, with median length slightly shorter than lateral margins of tergum IX in dorsal view ( Fig. 5B ). Preanal appendages represented by pair of transverse setose concavities along almost entire border of segment IX in dorsal view ( Fig. 5B ). Segment X broadly elliptical in lateral view, about 1.5 times as long as tall, parallel-sided in basal 3/4, ending apically in blunt 82° angle ( Fig. 5A ); in dorsal view, deeply divided into two very thin, vertical lobes, appressed against each other with dorsal margins normal, not flattened or expanded, each lobe about 5 times as long as its basal width ( Fig. 5B ). Inferior appendages each with coxopodite curved slightly caudoventrad, gradually narrowing from base to tip in lateral view, length between base of coxopodite and its subapical lobes at least 3.5 times its width ( Fig. 5A ); two subapical lobes nearly identical in shape and size ( Figs. 5A, 5B, 5C ). Harpago slender, embedded between subapical lobes, apex curved dorsomesad and sparsely covered with short, fine setae on tip ( Fig. 5E ). Phallus short, stout, length about 1.8 times height, with dorsal and ventral margins slightly sinuate; phallobase narrow for short distance at base, bulged at distal 2/3, phallicata completely retracted within phallobase in our specimens; ejaculatory duct conspicuous, phallotremal sclerite small, oval in lateral view ( Fig. 5D ).

Distribution: Oriental Biogeographic Region, southern China (Yun-nan); Thailand.
