Ichnotropis bivittata Bocage, 1866

Angolan Rough-scaled Lizard ( Fig. 19 , Map 19) Material (1 specimen): PEM R23530, west of Cuito town on Aludungo road, -12.32784° 16.90673°, 1,742 m asl. Description: 35 midbody scale rows; 10 longitudinal rows of enlarged ventral plates; 31 transverse ventral scale rows; 4/4 supralabials; 6/6 infralabials; 4/4 supraciliaries; 19 subdigital lamellae under 4 th toe; 10/10 femoral pores per thigh. Largest female: 59.9 + 98.0 mm (PEM R23530). Comment: Collected outside of the core study area, but it contributes to the distributional data for both the species and the region. Laurent (1964) described I. b. pallida from Huíla based on duller coloration and minor differences in head scalation. Recently, Butler et al. (2019) and Bandeira (2019) erroneously referred material from Bicuar National Park to I. b. pallida, but these are actually subadult non-breeding I. capensis (see Baptista et al. 2019 and the following species account). Bandeira (2019) found that material from the type locality of I. b. pallida (KTH09-075 and AMB 10722) shows very little genetic difference from typical I. bivittata (JVV 2970 and CAS 258409), and thus should remain in the synonymy of the latter until more material becomes available for a detailed phylogenetic study.
