Type locality: Alto Cuílo, Lunda Sul Province, northeastern Angola [-10.0°, 19.58333°, 1256m a.s.l.]
|Types||Holotype. MD 5312b, collected by an unidentified local, on November 1954.|
Paratype. Two adult males (MD 5312a, 5312c) and one adult female (MD 5312d), with the same collecting data as the holotype.
|Diagnosis||Diagnosis. A medium sized Lygodactylus species. Lygodactylus tchokwe sp. nov. can be distinguished from its congeners by the following combination of characteristics: 1) three scales surrounding the nostril (one supranasal, 1st supralabial and one postnasal); 2) nostrils separated from the rostral and pierced between supranasal and the up- per limit of first supralabial; 3) mental followed by three postmentals; 4) first infralabial < 25–50% overlap with postpostmental; 5) 15 to 16 rows of ventral scales at midbody; 6) 2–4 precloacal pores; 7) median subcaudals (in a rengenerated tail) arranged in a row about 1⁄4 or less of the width of the tail (Fig. 4E); 8) venter cream 9) gular region without markings (MARQUES et al. 2020).|
Comparison with other South and Southwestern African Lygodactylus. The species differs from L. angolen- sis and L. chobiensis in having fewer precloacal pores (2 to 4 versus 7–10 in L. angolensis and 7–11 in L. chobiensis) (Fig. 2). It may be distinguished from L. nyaneka sp. nov. and L. capensis by having three scales surrounding the nostril (versus four in L. nyaneka sp. nov. (Fig. 3) and five in L. capensis), and from L. bradfieldi and L. capensis by having the nostril separated from the rostral (versus nostril contacting rostral). It differs from L. lawrencei by the lack of gular ornamentation in males, and by having the nostrils separated from the rostral, in contact with the supra- nasal and pierced near the dorsal margin of the first labial (versus nostrils separated and pierced between supranasal and first labial; Fig. 3, MARQUES et al. 2020).
Variation. Variation in scalation and body measurements of the type series is reported in Table 5. The female paratype agrees almost entirely with the holotype, although the markings on gular region are more faded. The male paratypes both have four precloacal pores (MARQUES et al. 2020).
|Etymology||The specific epithet “tchokwe” is given in honor of the dominant ethnolinguistic group of the region where the species exists.|
