Identification:
This is a medium-sized rock gecko species, with a body length ranging from 70.3 to 82.9 mm. The dorsal surface features 5 to 7 white spots along the spine, extending from the nape to the sacrum. The flanks exhibit 4 to 7 pairs of short, white streaks between the forelimbs and hindlimbs. There are 12 to 16 rows of tubercles along the dorsal region. A total of 90 to 101 scale rows encircle the midbody. Between the lateral folds, the ventral region has 28 to 38 scale rows. Males possess 8 to 11 precloacal pores arranged in a series. Femoral pores are absent. The fourth toe of the hind foot has 17 to 18 subdigital lamellae.
Biology and Ecology:
This nocturnal reptile species inhabits rocky areas near streams within high-altitude evergreen forests, at elevations between 200 and 600 meters. They are typically active at night, resting during the day in narrow crevices within the rocks. Their diet consists of insects found in their habitat. They lay two eggs in crevices and cracks within rock faces at the beginning of the rainy season each year. The species name honors Russell Errol Train, Chairman of the International Environmental Protection Fund.
Distribution:
This species is endemic to Vietnam. It was recently discovered in the Chứa Chan Mountain area of Đồng Nai province and shares its habitat with the gecko species Cyrtodactylus huynhii.
