(1) SVL, males, 23.6-24.3, n = 4; females, 27.8-32.5 (x = 30.0; n = 12); (2) disc on Finger III expanded; (3) Finger I slightly shorter or equal than Finger II; (4) fringe present on Finger II; (5) disc on Toe IV expanded; (6) fringe present on Toe IV; (7) outer metatarsal fold present; (8) toe webbing formula I1 —2II1 —2 III2—3(3 ) IV3 —2)V; (9) dorsolateral stripe absent; (10) oblique lateral stripe present, inconspicuous in some specimens; (11) ventrolateral stripe absent; (12) discrete marks absent on chest; (13) throat dark in males, white spots on dark ground color on venter of females; (14) Finger III not swollen in males; (15) testes white (Coloma, 1995).Colostethus fuliginosus is compared with those species that have extensive toe webbing and either have or lack an inconspicuous oblique lateral stripe (C. chocoensis and C. bocagei ). It is distinguished from them by having well-defined spotted or marbled patterns on the venter, and a larger size. 

Description.—An appropriate description of the lectotype and paralectotype (MNCN 1585-86, both females) is not possible because they are poorly preserved. Measurements of these specimens are—MNCN 1585: SVL 32.2, tibia length 15.1, head length 11.2, head width 12.3, eye diameter 4.9, eye-nostril distance 2.1; MNCN 1586: SVL 32.5, tibia length 14.6, head length 10.2, head width 10.6, eye diameter 4.7. Following is a description of KU 143087 from a series of specimens from the Río Azuela, 1740 m, Provincia Napo. An adult female, 29.5 SVL; body robust; head about as long as wide; head length 34.0% SVL, head width 34.1% SVL; snout bluntly rounded in dorsal view, and in profile; loreal region barely concave; nostrils slightly protuberant laterally; eye-nostril distance 48.8% diameter of eye; supratympanic fold weak, diffuse, obscuring posterodorsal part of tympanum; tympanum diameter 40% diameter of eye; forelimbs moderately long; Finger I slightly shorter than Finger II; fingers having lateral keel-like fringes; fringes between Fingers II and III extending proximally as a small web; terminal discs moderately expanded; disc on Finger III about 1.6 times wider than distal end of adjacent phalange; subarticular tubercles low, round, oval; palmar tubercle large, rounded, barely elevated; thenar tubercle moderately rounded, small, bordered at inner side by three smaller, rounded tubercles; hind limbs moderately robust, tibia length 47.1% SVL, foot length 45.1% SVL; outer tarsal fold absent; inner tarsal fold nearly straight on distal half of tarsus; outer metatarsal tubercle round, about half size of elliptical inner metatarsal tubercle; toes webbed without narrow lateral fringes I1 —2II1 —2 III2—3IV3 —2V; terminal discs expanded, about twice width of digits; subarticular tubercles small, round; supernumerary tubercles absent.Skin of dorsum and venter smooth, flanks smooth, angle of jaw tubercular; anal opening directed posteroventrally at midlevel of thighs; anal sheath short; tongue elongately elliptical, narrow proximally, not indented posteriorly, free posteriorly for about one fourth of its length (Coloma, 1995).
