| Diagnosis | Diagnosis: To 49.3 mm SVL (Visser 1984 reported a maximum of 53.5 mm SVL but we examined no specimens in this size range). Pachydactylus serval may be distinguished from all other members of the P. serval/weberi group by the combination of the following characters: rostral enters nostril; supranasals in variable contact; scales on dorsum of head smooth and granular, those on snout larger than those of interorbital region; parietal scales tiny, granular, with no intermixed tubercles; dorsal scalation homogeneous, with only a few small, scattered flattened tubercles on sacrum and/or lumbar region; thighs without tubercles; toes relatively short with moderately wide pads; typically 5 undivided lamellae beneath digit IV of pes; tail to at least 107% SVL, moderately annulate, bearing whorls of small, rounded to pointed, unkeeled, white to yellow tubercles, widely separated form each other; adult pattern spotted, dark brown spots relatively large and arranged in more-or-less regular rows on a yellowish- to purplish-brown background, no nape band or nape band weakly evident; in some subadults adult spotted pattern and juvenile banding may cooccur; juvenile pattern of a light (white to ashy) nape band and a similar broad band across posterior abdomen and sacrum and extending on to hindlimbs (although typically becoming more brownish or blackish distally on limbs), remainder of body dark, blackish in life (see also Visser 1984:51), tail brownish [from BAUER et al. 2006]. |
| Comment | Synonymy: LOVERIDGE 1947 synonymized Pachydactylus montanus and P. m. onscepensis with Pachydactylus serval. This was followed by more recent authors (e.g. Wermuth 1965, Bates et al. 2014). Conradie et al. 2019, however, listed onscepensis as synonym of montanus. Pachydactylus serval purcelli BOULENGER 1910 has been elevated to full species status by BAUER et al. 2006. Distribution: Reports from Angola are likely to be P. punctatus [BAUER et al. 2006]. HABITAT: Pachydactylus serval is typically found under exfoliating flakes or in narrow crevices in a variety of rock types. Road embankments (Fig. 32), borders of dry riverbeds, low exposures on ridge tops and cliff faces are all occupied if suitable retreats are present. CONSERVATION STATUS.—Pachydactylus serval is patchily distributed and although infrequently encountered in comparison to some other members of the P. servalgroup, it is locally common and under no specific threats. |
