Chresonymy.

Amolops cremnobatus - Inger and Kottelat (1998: 30), Stuart (1999: 45), Bain and Nguyen (2001: 269), Orlov et al. (2002: 86, part), Stuart (2005: 476, part), Bain et al. (2007: 109, part), Cai et al. (2007: 51), Matsui et al. (2006: 661), Nguyen et al. (2009: 121, part), Luu et al. (2013: 295), Poyarkov et al. (2021: 44, part).

Types.

FMNH 252861, adult male holotype, FMNH 252862, adult male paratype (both examined). The type locality was given by Inger and Kottelat (1998) as "Laos, Khammouan Prov., Nam Phao River, just downstream from border post on Lak Sao/Vinh Road (18° 23'N / 105° 09 ’20”E).” This portion of the Nam Phao straddles the borders of Khammouan and Bolikhamxay Provinces, and the site described by Inger and Kottelat (1998) is actually on the Bolikhamxay side of that boundary. The type locality is amended here to Laos, Bolikhamxay Province, Khamkeut District, Nam Phao River, just downstream from border post on Lak Sao/Vinh Road, 18.38267N 105.15758 E.

Suggested Common Names.

Inger’s Lao torrent frog (English), ຂຽດເກາະຜາລາວອ ິງເກີ (Khiat Korpha Lao Inger; Lao).

Expanded diagnosis.

A member of the Amolops larutensis group having the combination of 2-3 faint vomerine teeth, sometimes absent; relative finger lengths I<II<IV<III; mean ± SE SVL of adult males 31.0 ± 1.3 mm (range 29.6-34.2 mm; n = 12) and of adult females 38.6 ± 1.7 mm (range 35.3-40.4 mm; n = 15); and tadpoles with BL 15.3 ± 1.1 mm (range 13.3-17.0 mm; n = 5).

Remarks.

Our examinations of the holotype and paratype agreed closely with the thorough description of Inger and Kottelat (1998) and the description is not repeated here beyond the addition of relative finger lengths I<II<IV<III [given only as "fingers short, first much shorter than second" in Inger and Kottelat (1998)].

Distribution and natural history.

This species is verified to occur in portions of Bolikhamxay and Khammouan Provinces, Laos, and Ha Tinh and Quang Binh Provinces, Vietnam (Fig. 1 View Figure 1 ; Table S1 and Table S2).
