ABSTRACT

Western Ecuador encompasses the Pacific lowlands, a series of low coastal mountains, and the

Andes, which

rise to heights

of more than 6000 m. Within this region, bioclimatic regimes range from humid

on the lowlands, from subtropical dry and subtropical humid environments on the lower slopes of the Andes to humid temperate and subtemperate forests, subparamo, and paramo at high elevations in the Andes. This region is inhabited by 61 species of Eleiitherodactylus, each of which is treated in tropical rainforest to desert

in

In southern Ecuador, it occurs in subparamo at elevations of 2010-2960 m (Lynch, 1979a). The species also is known from humid montane forests at elevations of 1850-2770 m in the Cordillera de Huancabamba in northern Peru (Duellman and

ELEUTHERODACTYLUS

III

Species of Eleutherodactylvs

Names

applied in the genus Eleiitherodactyhis with subgeneric assignments, species-group

assignments, the state of the lengths of Toes

III

and

V

(description of conditions in text), and

nomenclatural or taxonomic status (Comments). Series are employed (listed in parentheses) only for the subgenus Eleutherodactylus. (See text.) Species-group assignments are incomplete because not all

taxa are regularly assigned to groups (e.g.. Hedges, 1989). In the case of West Indian taxa,

we

some taxa we believe wrongly

introduce a novel species group {E. abbotti group) to accomodate

assigned to Euhyas by Hedges (1989); those taxa are here assigned to the subgenus Eleutherodactylus. Additionally,

we

elect to recognize only a martinicensis

combining much of what Hedges treated

Indies,

group (of the auriculatus series) in the West and montanus groups, because

as the martinicensis

Hedges did not assign many of the species of his auriculatus series to species groups. The subgeneric assignments used here include many novel ones and do not necessarily agree with the assignments made on the basis of the literature (e.g., Duellman, 1993). This is especially true for the subgenus Euhyas. Abbreviations for subgenera are: CR = Craugastor, EL = Eleutherodactylus, EU = Euyhas, PE = Pelorius, SY = Syrrhopus. Within the subgenus Eleutherodactylus, we employ several series abbreviated as follows: (a) abbotti, (b) binotatus, (c) conspicillatus, (m) martinicensis,

and

myersi. Toe conditions are:

(t)

A=

fifth toe

shorter than third,

not extending to distal subarticular tubercle of fourth toe,

C=
