Fig. 2 View Figure 2
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. (CHM). Paratypes: same data as holotype. 2 males: 1 male (PSUNHM), 1 male (CHM).
Diagnosis.
The male genitalia of the new species are moderately similar to those of Trichosetodes pales Malicky & Chaibu, 2006 described in Thailand, in the form of segment IX and inferior appendages, however, the phallus is clearly different. The phallicata of T. pales is divided into a dorsal branch, median branch and ventral branch, however, these features are missing in T. katiengensis . In addition, ventral lobes of inferior appendages are truncated and pointed in T. pales in both ventral and lateral views.
Description.
Length of each male forewing 3.5-4.0 mm (N = 3); specimens in alcohol with head, thorax, abdomen, legs, forewings dark brown.
Male genitalia (Fig. 2A-D View Figure 2 ). Segment IX with pair of thumb-like lobes posteriorly in dorsal view (Fig. 2B View Figure 2 ); right trapezoid, anterior margins convex with small lobe anterodorsally, posterior margin slightly truncated in lateral view (Fig. 2A View Figure 2 ); square with shallow notches anteriorly in ventral view (Fig. 2C View Figure 2 ). Preanal appendages thumb-like covered with hairs (Fig. 2A, B View Figure 2 ). Segment X not evident. Inferior appendages with dorsal and ventral lobes, dorsal lobe triangular in lateral view with sharp process basoposteriorly, ventral lobe tubular and truncated apically in lateral view (Fig. 2A View Figure 2 ); in ventral view, horn-like, bent inward, truncated apically (Fig. 2C View Figure 2 ). In dorsal view, phallus complex, phallicata divided into dorsal and ventral branches; dorsal branch with outer edge denticulated and ventral branch undulated with acute apex; ejaculatory duct short and thin (Fig. 2B View Figure 2 ). In lateral view, phallicata sickle-like with dorsal and ventral branches, dorsal branch of phallicata straight, covered with numerous short protrusions subapically, apex with small spines; ventral branch of phallicata claw-like, curved downward, acute apex; ejaculatory duct curved tube-like (Fig. 2D View Figure 2 ).
