Vanmanenia serrilineata Kottelat View in CoL

( Fig. 6 View FIGURE 6 )

Ƒanmanenia serrilineata Kottelat 2000: 76 (Nam Ou and Nam Tha basins in northern Laos); Chen, 2013: 465 (Nanla-he, Xishuangbanna in Yunnan; Mekong River basin in Laos); Endruweit 2014: 53 (Nanla-he River subbasin, Mekong basin, Xishuangbanna, Yunnan, China).

Material examined: KIZ 2012004200 View Materials , 1 View Materials ex., 64.9 mm SL, China: Yunnan: Xishuangbanna: Mengla County: Nanla-he River subbasin .

Diagnosis. Vanmanenia serrilineata is distinguished from congeners belonging to the barred group in Vanmanenia by the following combination of characters: the dorsal side of the head covered by a large black blotch (vs. several short dark brown vermiculations in V. striata and V. tetraloba ); the gill opening larger, its upper angle level with the middle point of the eye (vs. the gill opening smaller and its upper angle level with the lower edge of the eye in V. microcephala ); the dorsum possessing 4–5 black saddles (vs. 7–9 in V. striata ); and color pattern consisting of either 27–35 slim vermiculations with widths smaller than the eye diameter, 4 large cloud-like blotches about 3–4 times the eye diameter, or a series of irregular dark cloud-like blotches on the flank (vs. 12–16 regular bars with widths equal to the eye diameter, or with 3 large cloud-like blotches about 3–4 times the eye diameter in V. crassicauda (see Kottelat [2000], Figs. 66 and 68); vs. 14–22 vermiculations in V. microcephala , 16– 21 vermiculations in V. striata , and 10–15 regular bars in V. tetraloba ( Table 1 View TABLE 1 ).

Distribution: Known only from the Nanla-he, a branch of the Lancang-jiang drainage (the upper Mekong River) in Xishuangbanna, Yunnan, China and Nam Ou and Nam Tha basins in northern Laos, belonging to the Mekong River ( Kottelat, 2000) ( Fig. 4 View FIGURE 4 ).

Remark: Endruweit (2013) reported the distribution of Vanmanenia serrilineata , in the Nanla-he, Xishuangbanna, Yunnan, China. This was a new record of this species in China and the first report out of the type locality Nam Ou and Nam Tha basins in northern Laos, which indicated that the species was not a narrowly occurring species only distributed in the type locality. It also spread northward to the Nanla-he subbasin in Xishuangbanna, Yunnan, China, which is close to northern Laos.
