Of the 28 currently recognized species of skink in the genus Tropidophorus, four are recognized to occur in the Philippines (T. davaoensis, T. grayi, T. misaminius, and T. partelloi). Commonly referred to as Water or Keeled Skinks, this enigmatic radiation of Southeast Asian lizards consists of species that prefer habitat in and around stream and river systems.

In the Philippines, all four species are commonly observed underneath leaf litter, rocks, and collected piles of debris on the banks and in the middle of stream systems. Their unique morphologies make them easily identifiable in comparison to all other genera of Philippine lizards. Although variation in morphological characters has been documented between populations in the Philippines (Taylor, 1922), Brown and Alcala (1980) were the last to categorize and describe the country's diversity, recognizing only four species. The widespread species, T. grayi, exhibits large differences in adult body sizes between island populations, and likely includes multiple, unique evolutionary lineages in need of recognition.

There are only four recognized species of the genus Tropidophorus that are recongized to occur in the Philippines. Tripidophorus partelloi can be distinguished from its congeners by the following combination of characters: (1) keels on dorsal scales of body and tail terminating in moderately to strongly projecting spines; (2) midbody scale rows 28-32; (3) scale rows between parietals and base of tail 40-44; (4) 4th toe lamellae 21-26; (5) frontonasal single; (6) enlarged preanals 1 (rarely 2); (7) head shields with weak keels or embossing; (8) keels on scales of dorsum low, not forming strong spines; and (9) keels on scales of tail projecting posteriorly into strong spines (Brown and Alcala, 1980).

This species has been recorded only in southern Mindanao Island, Philippines.

Mindanao Pleistocene Aggregate Island Complex (PAIC; Brown and Diesmos, 2002).

This species is often encountered under loose leaf litter and logs on the forest floor as well as along the banks of streams. Individuals are also encountered mid-streams beneath piles of leaves and branches that have collected in the middle of the stream. Other individuals have been collected within rotting logs on the forest floor. The species is recognized to occur in low to mid-elevation forested habitat (450-1200 m; Brown and Alcala, 1980).

Reported to be ovoviviparous (Brown and Alcala, 1980).
