| Comment | Distribution: Not listed by GRANDISON 1977 for West Malaysia or Singapore. O. cinereus was reported from Borneo by DE ROOIJ (1917) under the name O. violaceus, but does not occur on Borneo according to MALKMUS et al. (2002). Specimens from Thailand identified as Oligodon cinereus multifasciatus and Oligodon cinereus swinhonis (Günther, 1864) are referred to Oligodon joynsoni (Smith, 1917) according to DAVID et al. 2011. Possibly in Bhutan (Lenz 2012). Subspecies: A morphologically variable species, Oligodon cinereus shows a variety of dorsal patterns (see Smith 1943), which have been used as a basis for describing several subspecies. However, the current intraspecific taxonomy of this species remains unresolved. Wagner (1975) showed in his unpublished MSc thesis that the differences between the various subspecies were unclear. Wagner refrained from accepting subspecies, a position that was followed by DAVID et al. 2011. O. cinereus is really several species (O. cinereus Günther (including O. v. pallidocinctus Bourret), O. swinhonis (Günther), O. multifasciatus (Jan) (including S. v. tamdaoensis Bourret), O. poilani (Bourret) (including S. v. plurimaculatus Bourret) [F. WAGNER, pers. comm.]. The original description is available online (see link below). Synonymy: Yushchenko et al. 2023 synonymized O. cattienensis with O. cinereus. These are quite variable species with brownish, greyish, or even greenish base color. See Figure 4 in VASSILIEVA et al. 2013 and Yushchenko et al. 2023: 76 (Fig. 1). |
| Etymology | Named after its color, Latin “cinis, cineris” = ash. O. cattienensis was named after its type locality, the Cat Tien National Park. Established in 1978, and covering about 72.000 hectares, CTNP is one of the most important areas for the conservation of biodiversity of the lowland forests in southern Indochina. |
