species:
Kalophrynus pleurostigma
Tschudi, 1838
.
DEFINITION
.— Small to medium-sized microhylid frogs (adults,
17–60 mm
SVL
) with deltoid to ovate dorsal body outline, narrowest anteriorly, and well-developed, moderate-length fore- and hindlimbs. Dorsal skin thick, surface typically granular, often spiny, and strongly glandular.
Skull with prevomer divided and postchoanal portion absent; palatine absent; ethmoids small or absent. Pectoral girdle with well-developed clavicles and procoracoids reaching ventral midline cartilage and laterally the scapulae; omosternum small, cartilaginous; sternum large, cartilaginous. Terminal phalanges T-shaped.
Pupil round to slightly horizontal elliptical. Tongue oblong to obovate, posterior edge blunt to rounded, and half to two-thirds free. Palate with two to three transverse ridges or folds, anterior one (vomerine) smooth, usually medially interrupted, and adenticulate just behind choanae, middle one (postorbital) smooth and adenticulate between posterior edges of orbits, and posterior one (buccal) variably segmented and adenticulate lying about halfway between rear of orbits and epiglottis.

4. General distribution of the
Kalophrynus interlineatus-pleurostigma
group. Solid circles denote specimens examined in this study; open circles are literature records and museum records of specimens not seen; stars represent type localities of available names. Source of the locality records are in Appendix Specimens examined section.
Tympanum always visible, although posterodorsal edge often partially overlapped by edge of thick glandular dorsal skin. Digit well-developed and not expanded distally. Forefoot usually without webbing or slight basal webbing, basal to moderate webbing on hindfoot. Both fore- and hindfeet with numerous subarticular tubercles. Commonly, snout with short, pointed proboscis.
