Diagnosis of Geckolepis humbloti Vaillant, 1887

Geckolepis humbloti is a species of Geckolepis that differs from all other species of the genus by the following combination of characters (see also Table 2): maximum SVL (65.3 mm), number of scale rows around midbody (22–30), number of infralabials to level of anterior margin of eye (3.0–4.0), number of ventral scale rows from postmentals to vent (33–41), and mental scale condition—innermost pair of large postmental scales in contact with each other posterior to mental scale (type E) or separated by a median postmental scale (type F).

G. humbloti is distinguished from the holotype of G. maculata (ZMB 9655) by a combination of maximum SVL (65.3 vs. 58.5 mm) and number of ventral scale rows from postmentals to vent (33–41 vs. 32). The following osteological characters are also noted to differ between the skulls of two scanned G. humbloti specimens and that of ZMB 9655: anterolateral corner of nasal bulging laterally (versus straight), frontoparietal suture straight (vs. curved posteriorly), subolfactory process ventromedially closed (vs. not closed), frontoparietal suture straight (vs. curved posteriorly), and posterior edge of fused paired parietals curved (vs. more or less straight). These are to be considered B potentially diagnostic^

For each cluster (species or population), all data is given for the 12S and the ND4 marker

Closest most closely related cluster, Intra largest intra-cluster divergence, Inter largest inter-cluster distance to closest relative until further data on the variation of osteology in these taxa are available.

G. humbloti is distinguished from G. typica by a combination of the following characters: maximum SVL (65.3 vs. 57 mm), number of scale rows around midbody (22–30 vs. 26–36), number of ventral scale rows from postmentals to vent (33–41 vs. 37–48), number of supralabial scales (5–7 vs. 6–7), number of infralabial scales (4–6 vs. 5–7), and arrangement of the postmental scales posterior to the mental scale (types E, F vs. types A, B, C, D).

G. humbloti is distinguished from G. polylepis by a combination of the following characters: maximum SVL (65.3 vs. 51 mm), number of scale rows around midbody (22–30 vs. 30–37), number of ventral scale rows from postmentals to vent (33–41 vs. 40–50), and number of infralabials to level of the anterior margin of the eye (3.0–4.0 vs. 4.0–5.5).
