Type material. Holotype male ( PSUNHM). Thailand: Prachuap Khiri Khan Province, Huai Yang Waterfall National Park , 11°36’32”N, 99°37’43”E, ca. 105 m a.s.l., 6 November 2016, leg. Pongsak Laudee. GoogleMaps

Etymology. Named for Asst. Prof. Dr. Niwat Keawpradubi, who is the President of Prince of Songkla University.

Description. Length of each male forewing 6 mm; specimens in alcohol with head, thorax, forewings, abdomen, and legs black.

Male genitalia ( Figs. 1–7 View FIGURES 1–7 ). In lateral view, segment VIII rectangular with two lobes dorsoapically, apical margin with numerous long and strong setae; in dorsal view with U-shaped incision apicomesally. Segment IX in lateral view longitudinally short, tall, without ventral process; in ventral view U-shaped. Preanal appendages small, round, with short setae. Segment X divided into two processes, upper processes slender, 2/3 as long as lower processes and tapering to acute apices, lower processes long, slender, dilate apically; in dorsal view upper processes of segment X tubular and L-shaped, lower processes tubular, curved inward, and rounded apically. Inferior appendages rectangular, each with bulging process apicoventrally, acute apex; in ventral view cylindrical with claw-like spine apically. Phallus in later view tubular, truncated apically ( Figs. 6, 7 View FIGURES 1–7 ).

Diagnosis. The male genitalia of C. keawpradubi n sp. appear similar to those of C. aneca Malicky and Chantaramongkol 1993 and C. matura Malicky and Chantaramongkol 1993 found in Thailand, C. haimuoinam Malicky 1995 found in Vietnam, and C. gerson Malicky 2009 found in Borneo. They share the character that the apicodorsal margins of segment XIII have numerous strong setae and segment X is divided into two pairs of processes. However, the new species is distinguished from the others by the characters of the inferior appendages, each with a bulging process subapicoventrally and a claw-like spine apically, which are not present in the previously described species.
