In preservative, yellowish tan and silvery-gold colors lost; black reticulations present on tail. _Remarks._--Cope (1876:105) described _Hyla elaeochroa_ from Sipurio, Limón Province, Costa Rica. He based his description on a small specimen, 26.0 mm. in snout-vent length, having a dorsum uniformly colored and lacking an interorbital triangle and blotches on the thighs. Cope (1887) described pigmented specimens from Nicaragua as _Hyla quinquevittata_, which he diagnosed as having dark brown bars on the hind limbs and five dark brown longitudinal stripes on the dorsum, the median one of which was expanded anteriorly so as to form a large triangular spot between the eyes. He thought this species was related to _Hyla eximia_ Baird and noted that "the hinder legs are much larger; the muzzle is more acuminate and the color bands are much wider" than in _eximia_. Cope did not compare _quinquevittata_ with _elaeochroa_, which he had described ten years before. Günther (1901:268), Noble (1918:340), and Nieden (1923:251) regarded both _elaeochroa_ and _quinquevittata_ as valid species. Dunn and Emlen (1932:25) regarded both as synonyms of _Hyla rubra_, but they made no qualifying statements. Taylor (1952:859) placed _quinquevittata_ as a synonym of _elaeochroa_ and indicated that _rubra_ was another species. Taylor (1958:37) described _Hyla dulcensis_ from the humid tropical forests of Golfo Dulce, Puntarenas Province, Costa Rica. He thought this species was "related to _H. elaeochroa_ but differs in its somewhat larger size, smaller finger and toe discs, the obsolete canthus rostralis; the loreal region concave and the choanae larger." Duellman (1966a:270) compared adults, tadpoles, and mating calls of _dulcensis_ and _elaeochroa_ and concluded that a single species was involved.
