ResumoEleutherodactylus jota sp. nov. is named from Bocas del Toro province in western Panama. It is closely allied to E. bransfordii (with which it is sympatric) and E. podiciferus (found at higher altitudes) but readily differs from each in having folds along the forearm and tarsus, a calcar, and a short first toe, as well as in snout shape. In the course of searching for a Middle American representative of the discoidalis Group of Eleutherodactylus, I found a small sample of a distinctive Eleutherodactylus species from western Panama. Although superficially resembling E. dolops Lynch & Duellman, E. elassodiscus Lynch, E. mantipus (Boulenger), and E. nigrovittatus Anderson (the discoidalis Group representatives of northwestern South America), the Panamanian frogs have feebly areolate skin of the venter and a short first finger as do E. bransfordii (Cope) and E. podiciferus (Cope). All of these frogs have broad vomerine odontophores (Fig. 1C). In the account below, the following abbreviations are employed: SVLsnout-vent length; HW--head width; IOD--interorbital distance; E-Neye to nostril distance. Eleutherodactylus jota sp. nov. Holotype. KU 115212, an adult female, obtained along the Rio Changena, Provincia Bocas del Toro, Panama, 830 m, by Linda Trueb 18 May 1966. Paratypes. KU 115213-17, collected syntopically. Diagnosis. A small Eleutherodactylus (4 adult females 24.5 to 28.5 mm SVL) similar to E. bransfordii (Cope) and E. podiciferus (Cope) in habitus but differing from each in having prominent ulnar and outer tarsal folds, a calcar on the heel,; depressed snout, and in lacking discs on fingers. The inner metatarsal tubercle is much shorter than the first toe in E. bransfordii and E. podiciferus whereas it is as long as the first toe in E. jota.

Head narrower than body, broader than long; HW 40.844.2 ( = 42.6, n = 6) percent SVL, broadest in two juvenile females; snout ovoid in dorsal view, depressed and somewhat pointed in profile (Fig. 1); snout long, E-N 83.3-100.00 (v = 94.4, n = 6) percent eye length; nostrils protuberant, directed dorsolaterally; canthus rostralis sharp, slightly concave; loreal region flat, sloping abruptly to lips; lips not flared; upper eyelid bearing 3-6 small, non-pungent tubercles, its width 44.2-60.5 ( = 54.8, n = 6) percent IOD; no cranial crests; temporal region slightly sloping (not vertical); tympanum superficial, annulus not distinct unless specimen dries; tympanum higher than long, its length 60.0-73.9 (i= 64.8, n = 6) percent eye length; tympanum separated from eye by distance equal 1-1/2 tympanum lengths; supratympanic fold indistinct above tympanum, prominent posterior to tympanum, not concealing tympanic annulus; subconical postrictal tubercles posteroventral to tympanum; a prominent fold extends from posterolateral corner of upper eyelid posteriorly onto anterior flank where it is deflected ventrally as an interrupted series of large warts. Choanae well lateral on roof of mouth, separated by distance equal to 8-9 times diameter of a choana, not concealed by palatal shelf of maxillary arch; vomerine odontophores of adult females massive, lying between and posterior to choanae, broad, each bearing a transverse row of 9-14 teeth, separated medially by space less than a choanal diameter; in two juvenile females (KU 115213, 115216) there are 6-9 vomerine teeth per odontophore and the odontophores are separated by a distance equalling the width of an odontophore; tongue slightly longer than wide, its posterior border not notched, posterior 12 not adherent to floor of mouth. Skin of head smooth except for eyelid tubercles, temporal folds, and pair of low postocular folds which converge (but do not touch) just posterior to scapular region and then diverge, becoming inperceptible at about level of sacrum; posterior to sacrum, especially laterally, are isolated, relatively large, subconical warts; just anterior to vent, skin of dorsum bears numerous minute warts; flanks bearing pungent tubercles, becoming smaller, more closely packed, and flatter toward lower flanks; throat and venter smooth except for encroaching tubercles from lower flanks; discoidal folds absent; anal opening not modified, no enlarged para-anal warts; skin on undersides of limbs smooth except for undersides of thighs below and ventrolateral to vent (coarsely areolate). Upper surface of forearm bearing longitudinal fold reaching to wrist; ulnar edge of forearm with a more prominent fold, feebly crenelate; palmar tubercle flat, slightly longer than wide, not bifid; thenar tubercle flat, oval; supernumerary palmar tubercles indistinct except for two lying between palmar tubercle and basal subarticular tubercle of finger IV; subarticular tubercles not pungent, that on I longer than wide, others round or slightly wider than long; no lateral keels on fingers; finger tips pointed, weakly This content downloaded from 157.55.39.208 on Fri, 14 Oct 2016 04:27:37 UTC All use subject to http://about.jstor.org/terms VOLUME 83, NUMBER 3 103 i:o-:o ' . +,e, '!'. .j ): !i i .
