. Ecuadorian frogs of the genus Colostethus (Anura:Dendrobatidae) . 600 M. CONTOUR OVER 3000 M J OVER 5000M 040 100 KILOMETERS - 5 Fig. 15. Distributions of Colostethus mystax{0), C. pulclwllus(A). C. pumilus (hexagon). C. delatorreae (â ). C. vertebralis (â¼), and C. whymperi (â¦). arm and hind limbs white, except gray on lower arm, palmar and plantar surfaces. Measurements ofholotype (mm): SVL , tibia length , head length , head width , eye diameter , eye-nostril distance , tympanum diameter Variation.âMale (RMNH 25248) has a gray throat in contrast to females and the holotype (sub- adult male) that have immaculate white throats. Color patterns in other specimens are like the holo- type except some specimens that have fewer white stipples on the posterior part of the flank. Some specimens lack webbing on the toes. A recently metamorphosed juvenile (CAS 10591) has a SVL of mm and basal webbing. The dorsum is uniform brown and the throat is stippled with black.
