Three new species of woodlizards (Hoplocercinae, Enyalioides) from northwestern South America.

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: Although previously referred to Enyalioidesoshaughnessyi, the possibility that the specimens here named Enyalioidesaltotambo represented a distinct species was recognized in previous studies. In a phylogenetic analysis of hoplocercine lizards, Torres-Carvajal and de Queiroz (2009) found “Enyalioidesoshaughnessyi” to be paraphyletic relative to Enyalioidestouzeti based on three samples of “Enyalioidesoshaughnessyi”. One of them corresponded to the paratype of Enyalioidesaltotambo, and was sister to a clade containing the sister taxa Enyalioidestouzeti and Enyalioidesoshaughnessyi. Torres-Carvajal et al. (2011) noted that the color of the iris in live specimens of “Enyalioidesoshaughnessyi” from Alto Tambo was not bright red as in live specimens of “Enyalioidesoshaughnessyi” from other localities and suggested that the two forms represented separate species. Nonetheless, these authors found no other differences between the two potential species and refrained from associating the name Enyalioidesoshaughnessyi with one versus the other because the type locality data of Enyalioidesoshaughnessyi is vague (“Ecuador”), and the color of the iris was not recorded in its original description (Boulenger 1881). Here we recognize known populations other than that at Alto Tambo as Enyalioidesoshaughnessyi based on the enlarged, circular and keeled scales scattered on the flanks of Enyalioidesoshaughnessyi (absent in Enyalioidesaltotambo), as described and illustrated in its original description (Fig. 4; Boulenger 1881).
