|Types||Lectotype: ZMB 7467, designated by Siler et al. (2014); Other syntype: CAS 64232.|
|Diagnosis||Diagnosis. Parvoscincus leucospilos can be distinguished from congeners by the following combination of characters: (1) body size medium (SVL 42.6–54.4 mm); (2) Toe-IV lamellae 15–17; () supralabials six or seven; (4) infralabials 6–9; (5) midbody scale rows 0–4; (6) paravertebral scale rows 61–67; (7) prefrontals in medial contact; (8) prefrontals contact first supraocular; (9) frontoparietals fused; (10) head pigmentation heavily mottled; (11) upper arm pigmentation absent; (12) subcaudal pigmentation absent; (1) dorsal white spots large, well- defined; (14) dorsal white bands 9–1; (15) lateral body coloration bright reddish-orange; (16) tail dorsolaterally compressed; and (17) semi-aquatic (Tables 2, ) (Siler et al. 2014).|
Comparisons. Parvoscincus leucospilos most closely resembles P. duwendorum, P. manananggalae, and P. tikbalangi. However, P. leucospilos differs from these three taxa by having head pigmentation heavily mottled (vs. moderately mottled; Figs. 4, 5), and by the absence (vs. presence) of dark pigmentation on the upper arm surface. Parvoscincus leucospilos further differs from P. duwendorum and P. manananggalae by having prefrontals in medial contact (vs. separated); from P. duwendorum and P. tikbalangi by having dorsal white spots large and well-defined (vs. faint); from P. manananggalae and P. tikbalangi by the presence of bright reddish-orange lateral coloration (vs. absence of coloration [P. manananggalae], presence, reduced, tan [P. tikbalangi]); from P. duwendorum by having a greater number of Toe-IV lamellae (15–17 vs. 12), a greater number of paravertebral scale rows (61–67 vs. 60), a greater number of midbody scale rows (0–4 vs. 26), a tendency towards a greater number of longitudinal ventral scale rows (41–47 vs. 41), and fewer dorsal white bands (9–1 vs. 15); from P. manananggalae by the absence of subcaudal dark pigmentation (vs. presence); and from P. tikbalangi by having a tendency towards a greater number of paravertebral scale rows (61–67 vs. 58–6) and a tendency towards a greater number of midbody scale rows (0–4 vs. 28–2). (Siler et al. 2014).
|Comment||Synonymy: Parvoscincus leucospilos (s.l.) has been split up into several species by Siler et al. 2014.|
|Etymology||The specific epithet “leucospilos” apparently refers to the distinctive coloration of this species, consisiting of prominent rows of white (from the Latin adjective “leucos”) spots (Latin, noun, “spilos”) down the dorsal surfaces of the body.|
