Gekko porosus group

( Figure 6 D)

Species. G. crombota Brown, Oliveros, Siler & Diesmos, 2008 ; G. gigante Brown & Alcala, 1978 ; G. porosus Taylor, 1922 ; G. ro m b l o n Brown & Alcala, 1978 ( Figure 6 D); G. ro s s i Brown, Oliveros, Siler & Diesmos, 2009.

Characters. 89.2–108.2 mm SVL; nares in contact with rostral; nasals 3; postmentals relatively large; dorsal tubercle rows 12–22; precloacal pores 52–88; postcloacal tubercle single; no webbing between fingers and toes; tubercles present on fore and hind limbs; lateral folds without tubercles; subcaudals enlarged, in a longitudinal row; green to blue coloration of the iris; head pattern without a distinctive

(e.g. W-shaped) pattern; dorsum with flecks ( G. gigante indistinctly banded).

Distribution. Philippines ( Figure 3 B).

Remarks. G. p o ro s u s was, for a long time, only known from the juvenile holotype (CAS 60526) (see Taylor 1922b), which was redescribed by Brown & Alcala (1978). The redescription by the latter authors led to slightly smaller measurements, and they did not mention the dark dorsal flecks that were visible in the freshly collected holotype. Brown et al. (2009) redescribed G. p o ro s u s using new material: three adult males with transverse rows of spots.
