|Comment||Synonymy: HOSER (2000) described several new subspecies of Leiopython albertisii and a new species, Leiopython hoserae. However, due to their vague description we list them as synonyms of Leiopython albertisii. For example, Leiopython albertisii barkeri is diagnosed as “separated from L. albertisii albertisii by the mutually exclusive distribution and by analysis of mitochondrial DNA [of which no data is provided]. Ventral counts for this species are near the lower limit for the range for New Guinea L. albertisii.” L. a. bennetti is described as follows: “Essentially similar in most respects to L. albertisii albertisii from which it can usually be differentiated by its higher loreal count. L. albertisii albertisii usually has a single loreal in broad contact with the prefrontal. The three specimens listed above are typical for their subspecies in that they have two or three loreals on each side. Specimens of L. albertisii albertisii usually have a single pair of elongated prefrontal scutes with their median suture three or more times as long as the suture between the internasals. However in L. albertsis bennetti it is not unusual for there to be a pair of small lateral prefrontals, broadly separated from each other by the median prefrontals but in contact with the frontal posteriorly and with the more posterior loreal anteriorly”.|
In Hoser's (2000a) python paper, the name barkeri requires emendation to barkerorum, and bennetti to bennettorum, as the subspecies were each named after two people (WÜSTER et al. 2001).
Diagnosis.—Leiopython albertisii is distinguishable from Leiopython hoserae, Leiopython bennettorum, and Leiopython huonensis sp. nov. by the presence of two pairs of parietals. A pair of large scales often separated from the median line by one or more small interparietal follows the anterior pair (Fig. 2A). It further differs from the former two species and from Leiopython fredparkeri sp. nov. by the presence of whitish postocular spots, and can easily be distinguished from Leiopython bennettorum in the number of loreals and prefrontals (Table 3), the average number of postoculars), dorsal midbody rows, ventrals, and subcaudal scales. Leiopython albertisii further differs from Leiopython hoserae and from Leiopython fredparkeri in lighter dorsal color and in having a yellowish flank (Parker, 1982; Barker and Barker, 1994; O’Shea, 1996, 2007), smaller average body size in hatchlings and adults, and additionally from Leiopython hoserae by molecular evidence (see Fig. 4). Leiopython albertisii can be distinguished from Leiopython biakensis sp. nov. by higher average subcaudal (71.5 +/- 2.85; range = 65–79, N = 30 vs. 67.5 +/3.54; range = 65–70, N = 2), and supralabial scale counts (12.9 +/- 0.28; range = 12–13, N = 30 vs. 11.8 +/- 0.35; range = 11–12, N = 2) along with a higher number of supralabials entering the eye (3.0 +/- 0.18; range = 2–3, N = 30 vs. 2, N = 2) [from SCHLEIP 12008].
