dos Santos FM, Entiauspe-Neto OM, Araújo JS, de Souza MB, de Lema T, Strussmann C, de Albuquerque NR (2018) A new species of burrowing snake (Serpentes: Dipsadidae: Apostolepis) from the state of Mato Grosso, Central-West region of Brazil.

During a faunal rescue conducted at a hydroelectric power station constructed in a Cerrado savanna area in the state of Mato Grosso, a sample of five small stripe-patterned individuals of snakes of the genus Apostolepis Cope, 1862 document the existence of an undescribed species, which is named herein. The new species can be distinguished from its congeners by a combination of scale counts, number of maxillary teeth and color pattern. The new species is most similar to Apostolepis borellii Peracca, 1904, A. lineata Cope, 1887, A. nelsonjorgei Lema & Renner, 2004, A. nigroterminata Boulenger, 1896, A. serrana Lema & Renner, 2006 and A. underwoodi Lema & Campbell, 2017 in its coloration pattern. However, it is distinguished from these species by having a pair of triangular blotches covering portions of the third to sixth supralabials, a white nuchal collar, the shape of the fourth supralabial and the shape of the tip of tail, the number of supralabials in contact with parietals, the size of the anterior chinshields, the color pattern of the paraventral side, parietal and terminal scales, the width of dorsal stripes, and a distinct number of subcaudals. The new species occurs in areas within the Cerrado biome.

The taxonomic history of the South American Dipsadinae genus Apostolepis Cope, 1862 has been rather confusing, and researchers have long recognized the lack of a comprehensive review of taxonomy and phylogenetic relationships in this genus (
Apostolepis is particularly speciose in Brazil, where 32 species have already been recorded (

All measurements were made to the nearest 0.1 mm using digital calipers, except for snout-vent (SVL) and tail (TL) lengths, which were taken with a flexible ruler to the nearest 1.0 mm. Ventral scales were counted according to

A female (MCP 12096) collected in 2000 at the Manso multi-use reservoir and hydroelectrical power plant – locally known as APM Manso – constructed at the confluence of the rivers Manso and Casca, Chapada dos Guimarães (15°27’39”S, 55°45’00”W; 811 m.a.s.l.), Mato Grosso, Brazil, by the faunal rescue team. Paratypes. three males and one female, same locality as the holotype: MCP 14524 (male), MCP 14525 (male) and MCP 11372 (female), date of collection unknown, collected by the faunal rescue team, and UFMT-R 1933 (male) collected on 1 December 1999 by the faunal rescue team.
Apostolepis kikoi sp. nov. can be distinguished from all other Apostolepis by the combination of having five dorsal stripes (vs. dorsal stripes absent in A. ambiniger, A. ammodites, A. assimilis, A. breviceps, A. cearensis, A. dorbignyi, A. flavotorquata, A. multicincta, A. roncadori and A. tertulianobeui; the presence of seven stripes on the dorsum in A. gaboi and A. niceforoi; three stripes on the dorsum in A. cerradoensis, A. goiasensis, A. nigrolineata, A. quirogai and A. tenuis; a pair of narrow lateral stripes in A. barrioi; a pair of wide lateral stripes in A. albicollaris, A. dimidiata and A. polylepis); the presence of a white nuchal collar (vs. white nuchal collar absent in A. ambiniger, A. barrioi, A. breviceps, A. christineae, A. goiasensis, A. intermedia, A. lineata, A. longicaudata, A. niceforoi, A. nigrolineata, A. polylepis, A. quinquelineata, A. rondoni, A. serrana, A. striata, A. thalesdelemai and A. vittata); the presence of a triangular blotch covering portions of the third, fourth, fifth and sixth supralabials (vs. a light lateral spot below the eye, usually occupying the third and fourth supralabials in A. mariae); 15 scale rows at midbody (vs. 17 in A. polylepis); six supralabials (vs. five in A. breviceps, A. christineae, and A. vittata); second and third supralabials entering orbit (vs. only the third supralabial entering orbit in A. breviceps); preocular contacting nasal (vs. nasal and preocular separated by prefrontal in A. ammodites, A. arenaria, A. assimilis, A. breviceps, A. cearensis, A. dorbignyi, A. gaboi, A. goiasensis, A. intermedia, A. multicincta, A. phillipsi, A. polylepis, A. quirogai, A. tenuis and A. tertulianobeui); temporals absent (usually 0 + 1 in A. ammodites, A. assimilis, A. cearensis, A. mariae, A. niceforoi, A. nigrolineata, A. quirogai, A. tertulianobeui and A. thalesdelemai, and 1 + 1 in A. flavotorquata and A. quinquelineata); seven infralabials (vs. five in A. breviceps; five to six in A. nelsonjorgei and A. vittata; six in A. christineae, A. intermedia, A. multicincta; eight in A. gaboi and A. quirogai); four infralabials contacting the first pair of chinshields (vs. three infralabials contacting the first pair of chinshields in A. dorbignyi, A. intermedia, A. multicincta, A. tenuis and A. vittata); a higher number of ventrals than A. arenaria and A. striata (203–209 vs. 168–181 and 202, respectively); fewer ventrals than A. christineae, A. intermedia, A. longicaudata, A. nelsonjorgei, A. niceforoi, A. phillipsi, A. polylepis, A. serrana, A. tertulianobeui, A. thalesdelemai and A. vittata (203–209 vs. 211–248 in the latter eleven species); fewer subcaudals than A. borellii, A. intermedia, A. longicaudata, A. nelsonjorgei, A. serrana and A. tertulianobeui (26–30 vs. 32–55 in the latter six species); a higher number of subcaudals than A. lineata, A. niceforoi and A. polylepis (26–30 vs. 24, 23 and 20–25, respectively) and fewer maxillary teeth than A. longicaudata and A. phillipsi (4 + 2 vs. 5 + 2 in the latter two species).
Preserved specimens of Apostolepis kikoi sp. nov. are most similar to A. borellii, A. lineata, A. nelsonjorgei, A. nigroterminata, A. serrana and A. underwoodi in its general pholidosis and coloration pattern. However, the new species is distinguished from A. borellii by having its paraventral sides cream and unblemished (vs. blackish), a pair of triangular blotches covering portions of the third, fourth, fifth and sixth supralabials (vs. a small, trapezoidal blotch covering only the posterior half of the third and the entire fourth supralabial); tip of the tail conical (vs. rounded) and fewer subcaudals (vs. 26–30 vs. 32). Apostolepis kikoi sp. nov. can be distinguished from A. nigroterminata by having a triangular blotch covering portions of the third, fourth, fifth and sixth supralabials (vs. an irregular blotch on the posterior margin of the third to the anterior margin of the fourth supralabial – see also

Map of South America, illustrating the type locality (star) of Apostolepis kikoi sp. nov. – reservoir of Manso hydroelectrical power plant – Chapada dos Guimarães (15°27’39”S, 55°45’00”W, 811 m a.s.l.), Mato Grosso, Brazil, and locality records for Apostolepis nigroterminata (circles) in the Brazilian state of Acre and Peru based upon the material examined. Square indicates the type locality of Apostolepis nigroterminata.
The specific epithet honors Francisco Luís Franco (“Kiko”), a specialist in Brazilian snakes, as a tribute to his relentless friendship, dedication and enthusiasm as curator of Herpetological Collection Alphonse Richard Hoge of Instituto Butantan, São Paulo, Brazil (partially and tragically destroyed by fire on 15 May 2010).
MCP 12096 was selected as the holotype because the general color in life of A. kikoi was described from the live holotype before it was euthanized.
