Fig. 1 View Figure 1

Type material.

Holotype. Male. Cambodia: Ratanakiri Province: Banlung, Katieng Waterfall, 13°40'38"N, 106°58'33"E, elev. 203 m, 13.v.2022, Pongsak Laudee. (PSUNHM). Paratypes: Same data as holotype, 6 males: 2 males (PSUNHM), 2 males (CHM), 2 males (CUAC).

Diagnosis.

The male genitalia of the new species are moderately similar to those of T. sotet Oláh, 2013 described in Vietnam in the form of segment IX and inferior appendages, as well as of T. insularis Schmid, 1987 in the form of segment IX and segment X; but the phallicata or aedeagus is clearly different. The phallicata of T. sotet and T. insularis are divided into subbasodorsal branch and subbasoventral branch, whereas such features are missing in T. carmelae . The phallicata in T. carmelae bears tuft of long hairs in the middle of dorsal edge, which does not occur in T. sotet . The phallicata in T. carmelae is slightly bent upward subapically, while it is curved downward in T. sotet .

Description.

Length of each male forewing 4.5 mm (N = 5); specimens in alcohol with head, thorax, abdomen, legs, forewings light brown.

Male genitalia (Fig. 1A-D View Figure 1 ). Segment IX right trapezoid, anterior margin convex dorsally and truncated ventrally, posterior margin truncated in lateral view (Fig. 1A View Figure 1 ); rectangular with pair of notches anteriorly in ventral view (Fig. 1C View Figure 1 ). Preanal appendages thumb-like covered with hairs (Fig. 1A, B View Figure 1 ). Segment X produced in pair of javelin-like processes each with acute apex (Fig. 1A, B View Figure 1 ). Inferior appendages each with dorsal and ventral lobes, dorsal lobe broad rectangular, serrated dorsally with small triangular process, ventral lobe slender with acute apex directed dorsad in lateral view (Fig. 1A View Figure 1 ); in ventral view, claw-like, bent inward, each with inner broad tooth sub-basally (Fig. 1C View Figure 1 ). phallicata in dorsal view, slender, lancet-like, acute apex, with isolated bunch of long hair in the middle; ejaculatory duct tube-like, about half as long as phallicata length (Fig. 1B View Figure 1 ); in lateral view, phallus typically large, axe-like, broad basally, strongly curved backward subbasally, with isolated bunch of long hairs dorsally, bent subapically, sharp apex (Fig. 1D View Figure 1 ).

Etymology.

The species name is dedicated to Dr Carmela R. Centrino who works for United Nations Industrial Development, Vienna International Centre for Southeast Asian Countries.
