Figs. 9–12.
Type material. Holotype male (PSUNHM). Laos: Muang Khong Village, Don Klon Island, Li Phi Falls, Mekong River, 13°57’27”N, 105°55’27”E, 77 m a.s.l., 16 April 2016, leg. Pongsak Laudee.
Paratypes: Same data as holotype, 4 males: 2 males (CHM), 2 males (PSUNHM)
Etymology. Dedicated to Asst. Prof. Sompong Thongpong, who was Vice President of Prince of Songkla University, Pattani Campus, during 2008–2016.
Description. Length of each male forewing 6–7 mm (n = 3). Specimens in alcohol with head and thorax dark brown, mesoscutum dark brown in middle and light brown laterally, forewings light brown, abdomen light brown with dark brown terga.
Male genitalia (Figures 9–12). In lateral view (Fig. 9), segment IX rectangular, posterior margin with large Vshaped incision at upper 1/3, rounded anteroventrally; preanal appendages rectangular, truncate apically; segment X stout, triangular, nearly as long as inferior appendages, ventral margin obliquely angled upward from middle; each inferior appendage stout, tubular, subapicodorsal lobe bent caudad from 3/4 of its length, with long setae basoventrally and subbasoventrally, harpago very short, slender. In dorsal view (Fig. 10), preanal appendages triangular, fused basally for very short distance, convex laterally, widely separated distally; segment X oval, slightly longer than preanal appendages, with small apical incision. In ventral view (Fig. 11), basoventral lobe of each inferior appendage crescentic, broader before insertion of harpago, with numerous short setae ventrally. In lateral view (Fig. 12), phallus oval, convex dorsally, ventral margin slightly concave, with one long, curved, spearlike paramere spine.
Diagnosis. The new species is in subgenus Athripsodina Kimmins 1963. The male genitalia of the new species are similar to those of C. troilus and C. hebe. All of these species including the new species have similar lateral views of their genitalia. Ceraclea thongpongi n. sp. is distinguished from these species by the rectangular preanal appendages of C. thongpongi versus the triangular preanal appendages of C. troilus and C. hebe. Segment X of C. hebe is divided into two lobes but not those of C. troilus and C. thongpongi in which they are triangular. The apex of segment X of C. troilus is straight and directed caudad, but curved upward in the new species. The phallus of C. hebe has 2 phallic spines, but the new species only 1. The phallus of C. troilus is longer and more nearly tubular, but oval in lateral view in C. thongpongi n. sp. In dorsal view, the apical end of segment X of C. hebe is truncate and deeply incised, it is rounded and entire in C. troilus, but oval and notched apically in C. thongpongi n. sp. In ventral view, the subapicodorsal lobe of each inferior appendage of C. troilus is pointed and curved inward, in C. hebe it is rounded and curved inward, but in C. thongpongi n. sp. it is rounded and straight.
