Figure 2. Megophrys pachyproctus showing anal region 



Description of morphology : Body length of male 35.3-36 mm; head flattened, 

 length and width nearly equal; snout tip bluntly rounded, shield like, distinctly protruding 

 over lower lip, dorsal part of snout region concave; canthus rostralis very distinct, loreal 

 region vertical and cheek surface concave; nostrils not easily seen in dorsal view, they are 

 in the middle of snout and eyes; intemasal space equal with interorbital space but a little 

 larger than upper eyelid width; pupils vertical; tympanum oval, far away from eyes, 

 about same distance as diameter of tympanum; two slanting vomerine ridges, posterior 

 end swollen, bearing teeth, right and left not in contact; posterior end of tongue rounded, 

 weakly notched. 



Forearm narrow; finger tips rounded; no web between fingers; fingers long and 

 narrow, digital formula: 3,4,2,1, first and second fingers nearly equal in length; no 

 subarticular tubercles; inner metacarpal tubercles flattened but not very distinct. Fhndlimb 

 long, tibio-tarsal articulation reaches anterior to eye, right and left heels slightly 

 overlapping, tibia length does not reach half of body length; toe tips rounded; no lateral 

 fiinges on toes, no web between toes; toes long and narrow, third slightly longer than fifth 

 toe; no subarticular tubercles; at the base of the first toe is a swollen-like tubercle; inner 

 metatarsal tubercles flattened, no outer metarsal tubercles. 



Skin rough, dorsal body and four limbs all bear small light red warts both in rows 

 and sparse, warts on middle of posterior dorsal occipital region "X"-shaped; longitudinal 

 skin ridge from posterior supratympanic fold to hip with Ught red warts on it; skin folds 

 at upper eyelid with many distinct folds; supratympanic fold obtusely angled, the part 

 inclined to shoulder is thicker, warts also appear on folds; posterior end of the body of 

 male protrudes slightly and appears as an arc-shaped swelling, then inclines to ventral 

 body and reaches anal region. Dissected view: formed by a mass of adipose tissue under 

 protruding skin, posterior of female does not have arc-shaped swellmg. A few small 

 rovind warts appear on lateral body and dorsal part of four lunbs, femur and tibia are 

 typical; a pair of Ught colored white glands appear on lateral chest; a pair of posterior 

 femur glands present. 



In life, dorsal body brownish yellow or dark brown; triangular dark marking edged 

 with lighter color appear between the eyes; color along warts darker; upper lip edge bears 

 light alternating with dark longitudinal stripes, one below eyes larger; color below 

 supratympanic fold darker; 2-4 dark transverse stripes on forearms, and 4-5 on either 

 side of femur and tibia; grayish brovra or black-brown around vent, dorsally it is edged
