Description. Head: As described for N. kempi except face without medial horizontal brown line and parafacial only dark brown laterally; glossy facial spot enclosed dorsally by tomentose band, usually broadly so, reducing size of glossy spot.
Thorax: As described for N. kempi except as follows. Notum slightly paler overall, excluding spots on postpronotum and notopleuron (notopleural tubercle paler); scutum with medial stripe slightly narrower, tapering anteriorly or absent presuturally. Pale regions of scutellum sometimes darker orange or brown; venter of subscutellum yellower. Pleuron with brown and white stripes less distinct, faded; anatergite more orange in colour. Proepisternal lobe only brown along anterior margin. Eight rows of presutural acrostichal setulae in medial patch; lateral patch of 2–3 additional rows of setulae clearly delimited.
Wing: ( Fig. 72 View FIGURES 67 – 78 ) Wing length 6.2–6.8mm. As described for N. kempi except as follows. Subapical band expanding to a slightly greater width anteriorly, entirely filling apex of cell r1; infuscated apical region (excluding clear spots) sometimes darker; subapical cloud on CuA1 not extending into cell dm (i.e. as described for N. kuznetsovorum ).
Legs: As described for N. kempi .
Abdomen: As described for N. kempi except as follows. Anterolateral corner of tergite 2 more widely yellow. Tergite 3 with one pair of ill-defined and sometimes very faint lateromedial orange spots. Tergite 4 yellowishorange excluding dark brown anterior and posterior margins.
Male terminalia: ( Figs 84, 85 View FIGURES 84, 85 ) As described for N. kempi except surstylus with anterior margin strongly convex on basal half, and apex of pregonite straight rather than curved.
Variation. Thailand: Paratype male from Soppong with cloud on CuA1 reaching dm-cu; tergite 2 more widely yellow anterolaterally; tergite 5 shining, with large yellowish-orange anteromedial spot. Doi Suthep females with posterior margin of tergite 6 dark brown (stripe thickest sublaterally).
Etymology. The specific epithet is derived from the Latin for “waterfall”, as the holotype and a number of paratypes were collected near a waterfall.
Distribution. Laos, Thailand.
Holotype. THAILAND. Chiangmai Prov., Doi Inthanon NP, Mae Pan waterfall, 1050m, 18˚31.66ʹN, 98˚27.37ʹE, 7–8.v.2004, Ilan Yarom (1♂, TAU).
Paratypes: LAOS. Ban Van Eue, 13–15.iv.1965, J.L. Gressitt (1♀, BPBM). THAILAND. Chiang Mai Prov.: same collection as holotype (1♂, TAU), Chiangmai Prov., Doi Suthep, 28–31.iii.1958, T.C. Maa (1♀, BPBM), Doi Suthep, 4.iv.1958, J.L. Gressitt (1♂, CNC), Doi Suthep (water margin), 4.iv.1958, T.C. Maa (1♂ 1♀, BPBM), NW Chiangmai: Doi Suthep, 1278m, 29.iii–4.v.1958, T.C. Maa (1♂, BPBM; 1♀, CNC), water margin (2♀, BPBM), Mae Hong Son Prov.: Mae Surin NP, Mae Surin waterfall track, 18˚56.59ʹN, 98˚04.12ʹE, 12.v.2004, Ilan Yarom (2♂, TAU), NW Soppong, 8km S Rt. 1095, near Ban Nam Rim, 28–30.x.2002, D. Kovac (1♂, TAU).
Comments. Like Nothybus kuznetsovorum , N. cataractus differs subtly from other members of the N. kempi group, but tergites 2 and 3 are dark brown, there are additional rows of setulae medially on the scutum and the shape of the surstylus and pregonite are characteristic. Most specimens of N. cataractus were collected in Thailand, but a single female is known from Laos. The similar N. kuznetsovorum has also been collected in northern Thailand and Laos, but most records are from Vietnam.
