|Diagnosis||Diagnosis. Parvoscincus arvindiesmosi sp. nov. can be identified by the following combination of characters: (1) A small body size (SVL at maturity 36–43 mm); (2) MBSR = 32–36; (3) PV = 65–74; (4) dorsal scales non- striated with apical pits; (5) apical pits on forelimbs and hind limbs; (6) four enlarged supraoculars; (7) anterior and posterior loreals undivided laterally; (8) three preoculars; (9) and 16–19 Toe IV SDL; (10) narrow snout (IND/ RostL < 0.50).|
Parvoscincus arvindiesmosi sp. nov. is the sister species to P. agtorum and closely related to P. jimmymcguirei sp. nov., P. abstrusus sp. nov., and P. decipiens sensu stricto (Fig. 2). Parvoscincus arvindiesmosi sp. nov. can be distinguished from all these species by its narrow snout (IND/RostL 0.44–0.49 vs. > 0.50) and unique color pattern. In addition to the narrow snout, the new species differs from P. jimmymcguirei by lacking throat mottling (vs. heavy throat mottling); dorsolateral band extending dorsally towards midline and broken up along dorsum (vs. dorsolateral band bordered dorsally by large white checks, restricted to lateral regions); ventral edge of dorsolateral band abruptly transitioning to lateral body color (vs. ventral edge of dorsolateral band flecked with white and becoming a mix of dark brown and white spots ventrally).
Parvoscincus arvindiesmosi sp. nov. can be distinguished from P. abstrusus sp. nov. by having a single anterior loreal (vs. laterally divided anterior loreal) and by the presence of apical pits on the dorsal scales (vs. weak to missing apical pits); by having a white throat in males and light brown streaking in females (vs. throat black in males and white in females); presence of a broad dorsolateral band from the head to the tail (vs. dorsolateral band a thin strip along dorsal margin); dorsal coloration with brown mottling extending from the dorsolateral band (vs. dorsal coloration without mottling other than vertebral spots).
Parvoscincus arvindiesmosi sp. nov. can be distinguished from P. decipiens sensu stricto by having dark brown mottling on the dorsal surface (vs. light brown ground color without mottling); labials spotted with dark brown extending posteriorly to the forelimbs (vs. labials white without spotting).
Parvoscincus arvindiesmosi sp. nov. can be distinguished from P. agtorum sp. nov. by having a smaller SVL (30.89–43.14 vs. 44.91 mm); having fewer midbody scale rows (32–36 vs. 39); having apical pores on the dorsal scales (vs. lacking pores); having three preoculars (vs. two preoculars); by having a white throat (vs. a cream throat with brown speckling and a brown incomplete gular collar); and by the presence of a broad dorsolateral band extending from head to tail (vs. narrow dorsolateral band extending from eye to midbody).
|Comment||Habitat. This species is found under logs on stream banks, inside rotten logs and under logs and in leaf litter.|
|Etymology||The specific epithet is a patronym in the genitive singular, honoring the contributions of Arvin C. Diesmos to the ecology, conservation, and systematics of Philippine herpetofauna.|
