|Diagnosis||Description. “Frontonasal about as long as its maximum width; prefrontals in contact medially; frontal hexagonal, pentagonal in a few cases in which the posterior border is truncate; frontoparietals elongate and larger than the prefrontal; interparietal longer but narrower than the parietals; pair of postparietals, usually separated medially by a small occipital; a single transverse row of irregular flattened nuchals, not as large as in quadrilineatus; supraoculars 3; superciliaries usually 3, occasionally 4; suboculars 3-4; nostril in a divided or inferiorly grooved nasal; loreal large and usually in contact with the upper labials; the last 2 pairs of postmentals are widely separated medially by the pregulars; regulars bordering the post mentals larger than the median pregulars. Dorsals lanceolate (fig. 5), occasionally subhexagonal. Laterals like the dorsals but slightly wider. Ventrals truncate or lightly convex. There 2 are 2 large preanal scales; occasionally a very small lateral scale may be present on each side. Males with 3/3-5/6 femoral pores, females with 1/1-2/3 femoral pores. |
Scale counts. Midbody, 23-37; transverse dorsal rows, 30-36; trans verse ventral rows, 19-26; gulars, 7-8.
Color. The specimens examined show dichromatism in this sub species. About 40 per cent of the specimens are gray with a white stripe extending from each temporal region, passing above the ear and forelimb, dorsolaterally along the body and onto the tail. This stripe may be very distinct or faint. The dorsal surface of the head is gray and with a few black spots. Ventrally there is a dustlike flecking on each ventral. The rest of the specimens examined are melanistic, black or very dark gray-black, with the dorsolateral stripe faintly indicated or absent. Ventrally they are flecked with black or gray. In both forms each subcaudal has the central portion heavily pigmented.
Remarks (Variation). Of the 22 specimens examined 2 had the loreal separated from the labials by a forward extension of the frenoocular. Both these specimens (D.Z. 786, 789A) are from the northern range of this sub species; however, they do not resemble albostrigatus in any other character. One specimen (A.M.N.H. 17022) from Salta, Argentina, has a faint lateral white stripe from the lower half of the ear and along the neck. This specimen may thus be considered to be intermediate between schreibersii and parkeri. It is here considered as schreibersii because it is gray in color and has lanceolate dorsals, both of which are char acters found in schreibersii and not in parkeri.
The only sexual dimorphism observed is in the case of femoral pores. One female had 1/1 femoral pores, another had 2/3, while all the rest had 2/2. The males have 3/3 or 4/4 with the exception of a single specimen that has 5/6 (A.N.S.P. 12954).
In a few of the gray specimens the black-tipped dorsals typical of albostrigatus are present. However, there are few black-tipped scales and never arranged as in albostrigatus.” (Ruibal 1952)
|Comment||Synonymy partly after CEI 1993 and PETERS et al. 1970.|
Type: MSNTO R2173 [Pantodactylus borelli PERACCA 1894]
Pantodactylus schreibersii parkeri RUIBAL 1952 has been elevated to full species status.
Type species: Pantodactylus d’Orbignyi DUMÉRIL & BIBRON 1839 is the type species of the genus Pantodactylus d’Orbignyi DUMÉRIL & BIBRON 1839.
Phylogenetics: Pantodactylus clearly nests within Cercosaura, hence the resurrection by GOICOECHEA et al. 2016 doesn’t seem to be justified (TORRES-CARVAJAL et al. 2016).
|Etymology||Named after Dr. Carl Franz Anton Ritter von Schreibers (1775-1852), a zoologist who collected in Brazil (1817).|
