Cyrtodactylus sumuroi Welton, Siler, Linkem, Diesmos & Brown 2010

Cyrtodactylus sumuroi is a nocturnal species, encountered on the butresses of trees, exposed root bundles, and rocky outcrops along river drainages.

Cyrtodactylus sumuroi, a member of the C. agusanensis Species Complex, is a recently described species. It is similar in coloration to all other Philippine Bent-toed gekkos, with a dorsal ground color light brown to tan, overlain by medium to dark brown patterning. Transverse body bands characterized by minimal longitudinal elongations on either side of vertebral column, the tips of which are dark brown and confer a vague “bow-tie” shape.

Unlike its close relatives Cyrtodactylus agusanenis, C. sumuroi, and C. mamanwa, this species has not been encountered in high numbers. This is likely owed to minimal survey efforts that have been conducted within its distribution, and we suspect that this species is not heavily threatened.

We have evaluated this species against the IUCN criteria for classification, and find that it does not qualify for Critically Endangered, Endangered, Vulnerable, or Near Threatened status. Cyrtodactylus sumoroi has been documented to have a broad geographic distribution and is quite abundant at all sampled localities. We therefore classify this species as Least Concern, LC (IUCN, 2010).

Cyrtodactylus sumuroi generally has a light brown to tan dorsal base color, overlain with medium to dark brown patterning; head patterning moderately distinct, often with irregular dark speckling in loreal and temporal regions; canthal stripe light tan, bordered ventrally by medium brown stripe and extending from nostril to eye, stripes continuing from posterior margin of eye to nuchal region; supralabials with alternating light and dark blotches; occipital region with irregular medium brown speckling over light brown; nuchal region often with medium brown “V;” dark brown lateral stripe (extending form posterior margin of eye) continuing in nuchal region, and joined ventrally by more narrow medium brown stripe extending from posterior margin of auricular opening; trunk with medium brown transverse bands characterized by longitudinal elongations on either side of vertebral column, the tips of which are dark brown and confer a vague “bow-tie” shape; transverse bands connected dorsolaterally, by dark brown longitudinal stripe; lateral pattern blotched medium brown from dorsolateral stripe to lateral tubercle row; limbs with medium brown irregular bands and blotches; wrists with conspicuous solid dark brown bands; Fingers I and II absent of dorsal coloration, but all other fingers and toes with irregular medium brown bands; ground color of tail tan to gray; dorsal bands medium to dark brown, lacking conspicuous longitudinal projections of trunk. Ventral coloration generally tan to light cream; lighter coloration extending from infralabials and auricular opening, from medium brown lateral stripe in nuchal region, from lateral tubercle row in axilla–groin region, and from ventrolateral margin on limbs; hands and feet medium gray, originating at wrists and ankles; subcaudal region with tan ground color, with irregular dark brown blotches; tails overlain with lighter transverse bands.

Cyrtodactylus sumurois is diagnosed from other members of the C. agusanensis Species Complex by: (1) snout–vent length (2) numbers of midbody dorsals; (3) paravertebrals; (4) postcloacal lateral tubercles; (5) number of scales between precloacals and femorals; (6) number of tuberculate caudal annuli; (7) the presence of a canthal stripe; (8) anterior-posterior dorsal band projections minimal or absent; (9) cephalic tubercle size; (10) ventral coloration; and (11) dark dorsal bands fully enclosing light bands. Also, C. sumurois exhibits tendencies for fewer subdigital lamellai beneath Finger III, as well as fewer midbody ventrals. This species can be discerned from the remaining Philippine congeners by various combinations of: (1) snout–vent length; (2) dark dorsal bands fully enclosing light bands; (3) greater number of subdigital lamellae beneath Toe IV; (4) the presence of femoral pore-bearing scales; (5) greater number of midbody tubercle rows; (6) fewer paravertebrals; (7) fewer midbody dorsals; (8) more dorsal tubercle rows; (9) larger cephalic tubercles; (10) the presence of a canthal stripe; and (11) the number of tuberculate caudal annuli.

Cyrtodactylus sumuroi is restricted to Samar Island in the Mindanao PAIC faunal region. To date, survey efforts have yet to confirm the presence, or identity, of Cyrtodactylus populations on the western half of the island.

Like all Philippine Bent-toed gekkos, Cyrtodactylus sumuroi prefers exposed roots overhanging stream banks, from trunks of trees bordering flowing water, and from large boulders in river and stream beds.

The specific epither for Cyrtodactylus sumuroi was chosen in recognition of Juan Ponce Sumoroy, a Waray hero and popular Visayan leader of the "Sumuroy Rebellion" attempt of 1649. Although the Spanish suppressed the uprising and executed many of its leaders, by all accounts, Sumuroy and his co-conspirators did much to spread the quest for independence among the peoples of the central Philippines during Spanish rule.

Mindanao Pleistocene Aggregate Island Complex

Cyrtodactylus sumuroi has been encountered in riparian habitat corridors and gallery forests, on vegetation a few meters from the banks of rivers and streams.

This species will most likely be confused with other members of the Cyrtodactylus agusanensis Species Complex, but can be discerned by a variety of morphological and distributional characteristics.

As with other Philippine Bent-toed geckos, Cyrtodactylus sumuroi relies on riparian habitat corridors, gallery forests, and vegetation a few meters from the banks of rivers and streams. Preservation of this habitat is essential for maintaining this species in the future.

The mostly likely threats to this species come from habitat alteration and loss. As with all Philippine Cyrtodactylus, upland riparian corridors and karst outcrops are preferred habitats, and essential to the preservation of this species.
