Torres-Carvajal O, Venegas PJ, de Queiroz K - Zookeys (2015)

Bottom Line: Enyalioidessophiarothschildae sp. n. is from the Amazonian slopes of the Cordillera Central in northeastern Peru; it differs from other species of Enyalioides in having caudal scales that are relatively homogeneous in size on each caudal segment, a white gular region with a black medial patch and several turquoise scales in males, as well as immaculate white labials and chin.A molecular phylogenetic tree of 18 species of hoplocercines is presented, including the three species described in this paper and Enyalioidescofanorum, as well as an updated identification key for species of Hoplocercinae.Abstract available from the publisher.

ABSTRACT
The discovery of three new species of Enyalioides from the tropical Andes in Ecuador and northern Peru is reported. Enyalioidesaltotambo sp. n. occurs in northwestern Ecuador and differs from other species of Enyalioides in having dorsal scales that are both smooth and homogeneous in size, a brown iris, and in lacking enlarged, circular and keeled scales on the flanks. Enyalioidesanisolepis sp. n. occurs on the Amazonian slopes of the Andes in southern Ecuador and northern Peru and can be distinguished from other species of Enyalioides by its scattered, projecting large scales on the dorsum, flanks, and hind limbs, as well as a well-developed vertebral crest, with the vertebrals on the neck at least three times higher than those between the hind limbs. Enyalioidessophiarothschildae sp. n. is from the Amazonian slopes of the Cordillera Central in northeastern Peru; it differs from other species of Enyalioides in having caudal scales that are relatively homogeneous in size on each caudal segment, a white gular region with a black medial patch and several turquoise scales in males, as well as immaculate white labials and chin. A molecular phylogenetic tree of 18 species of hoplocercines is presented, including the three species described in this paper and Enyalioidescofanorum, as well as an updated identification key for species of Hoplocercinae.

Mentions: Variation in meristic and morphometric characters of Enyalioidesaltotambo are presented in Table 2. The single female paratype (QCAZ 6671; Fig. 2) is similar in lepidosis and color patterns to the holotype. It differs from the holotype in lacking a black gular patch, and in having a longer pale postympanic stripe, a yellow chin, and a yellow gular region. Furthermore, the scales on the lateral edge of the skull roof and those forming the vertebral crest are more projected in the female (Fig. 2); however, this variation could be ontogenetic rather than sexual because the female is larger (SVL = 134 mm) than the male (SVL = 119).
