Laos: Pakse Province</b> : Champasak, Khonphapheng waterfall, Mekong river, 13°57'30"N, 105°59'14"E, elev. 64 m, 8.iv.2019, Pongsak Laudee. (PSUNHM). <i>Paratypes</i>: same data as the holotype; <b>Laos: Vientiane province</b>: Nam Lik river, 18°31'29"N, 102°31'19"E, elev. 180 m, 8.iv.2019, Pongsak Laudee. 9 males: 2 males (PSUNHM), 3 males (CHM), 2 males (NMPC), 2 males (CUAC). Diagnosis. The male genitalia of <i>P. khonphaphengensis</i> sp. nov. are similar to those of <i>P. kaineus</i> Malicky &amp; Bunlue in Malicky et al. 2004 from Thailand. However, <i>P. khonphaphengensis</i> sp. nov. is strikingly different from <i>P. kaineus</i> and the other species of the genus by the usually broad, almost circular inferior appendages with 1.5 × longer than its width in lateral view, while the inferior appendages of <i>P. kaineus</i> are oval and 3.2 × longer than its width in lateral view. In addition, the phallus of <i>P. khonphaphengensis</i> sp. nov. bearing the hooked phallic sclerite which are lacking in <i>P. kaineus</i>. Description. Adult, male, length of each male forewing 4.0-4.5 mm (n = 9); general body color in alcohol yellow brown. Male genitalia as in Figure 2A-E. Segment IX narrow in lateral view, with anterior margin produced forward in ca. 100° angle. (Fig. 2B). Segment X bilobed, blunt apically in dorsal view; finger like with setae in lateral view. Preanal appendages, long, slender with setae, rounded apically in dorsal view and lateral view (Fig. 2A, B). Intermediate appendages hooked and turned dorsally then bend outward immediately in dorsal view (Fig. 2A); in lateral view hooked, slightly curved upward, pointed apically (Fig. 2B). Inferior appendages strikingly broad and rounded, total length &lt;2 × of its subapical width in lateral view (Fig. 2B); slender oviform, total length &lt;2 × of its width in ventral view (Fig. 2C). Basodorsal processes of inferior appendages curved with strong setae dorsomedially, pointed apically in lateral view (Fig. 2B); in ventral view, horn like, originated basodorsally, curved inward, each with tapering apex (Fig. 2C). Phallus, long, cylindrical, bulbous basally, straight laterally with hooked phallic sclerite intermediately, with numerous subapical spines in lateral view and dorsal view (Fig. 2D, E). Etymology. The species is named for the type locality, Khon Phapheng waterfall.
