The Calliophis Gray, 1835 includes 11 , method of counting ventrals is adapted from Dowling six known from South Asia and five from Southeast Asia (1951) and the dorsal scale rows were counted as (Uetz et al., 2019). All species are relatively small and described by Kaiser et al. (2018). The terminal scute semifossorial, and they are not frequently encountered. (tip) is excluded from the number of subcaudals. A Calliophis maculiceps (Günther, 1858) is distributed preanal scale is excluded from the number of ventrals. throughout Indochina and the Malay Peninsula, having The numbers of dorsal scale rows are counted at one been reported from , Laos, , , head length behind the head, at midbody, and at one , and . There are only few records head length before the vent. of the species from Laos, and these are restricted to the The specimen is an adult male (snout–vent length 302 provinces of Vientiane, Champasak, and Savannakhét mm, tail length 37 mm) with characteristics confirming (Deuve, 1970; Teynié et al., 2014). We here present its membership in C. maculiceps as follows: seven a first record of C. maculiceps from Khammouane supralabials, one preocular, two postoculars, eight Province. infralabials, smooth dorsal scales in 13-13-13 rows, While conducting fieldwork in Naden Village, 196 ventrals, 29 subcaudals, and cloacal plate divided. Yommalath District, Khammouane Province, Laos (17.5016°N, 105.3901°E, WGS 84; elevation ca. 170 m), we collected an individual of Calliophis maculiceps (Fig. 1). The fieldwork was conducted on 28 May 2018 in an open secondary forest, and we found the hidden under a deadwood on the sandy bank of a dried stream. The snake was euthanized using a solution of isoflurane, fixed in 10% formalin, and preserved in 70% ethanol. It was deposited in the Zoological Collection of Faculty of Environmental Sciences, National University of Laos, from where it was loaned to the Zoological Collection of Kyoto University (KUZ) under the voucher number KUZ R 74136. After the preservation we measured the specimen and counted the scales. The

The Calliophis maculiceps population from from the posterior edges of the parietals and posterior Laos would be recognized as C. m. michaelis Deuve temporals to the fourth dorsal scale along midline.

Most morphological characters of KUZ R 74136 ventral colour is orange with the lateral edges of the are identical to C. m. michaelis, but some characters ventrals forming a pinkish-white frame. The orange were not (196 ventrals in KUZ R 74136 vs. more than area begins on the ninth ventral scale and is initially a 200 in C. m. michaelis; series of only small spots on the narrow line with a relatively light orange hue, becoming dorsolateral area in the former vs. a series of alternately broader and more strongly coloured towards the cloacal large and small black spots on the dorsolateral area in plate (Fig. 1B). Two black bands circle the tail, the first the latter [Deuve, 1970; Golay, 1985]). Thus, while extending immediately behind the cloaca to the third we follow Cox (2000) in our identification, future subcaudals and seven dorsal scales long in the midline, taxonomic examination of this form is needed. the second extending from the 22nd to the 24th subcaudals with equal width dorsally.
