_Remarks._--_Hyla staufferi_ was described by Cope (1865:195) on the basis of specimens from Orizaba, Veracruz, México. He described the color pattern as "color above dark olive, with a short black bar over each scapula, and one from eye to eye, with a trace along the coccyx." Cope (1887:14) placed _staufferi_ as a subspecies of _Hyla eximia_, but he did not justify his action. Günther (1901:262) also considered _staufferi_ to be conspecific with _eximia_ without making any qualifying statement. Dunn and Emlen (1932:24) named _Hyla culex_ from Tela, Honduras, on the basis of a male (MCZ 16098) having a snout-vent length of 25.1 mm., and a female (USNM 20267) from Patuca, Honduras. They diagnosed the species as having "discs larger than tympanum ... black interorbital triangle, traces of black dorsal marking; three black bars on anterior and posterior face of thighs, two black bars on tibia, on tarsus and on forearm." The holotype now is faded but has some of the pattern described. Dunn and Emlen did not compare _culex_ with _staufferi_ but did compare it with _boulengeri_ and _rubra_. Dunn (1933:61) named _Hyla altae_ from Summit, Canal Zone. His description was based on a male (MCZ 17972) having a snout-vent length of 25.1 mm., the color pattern was described as "gray with four darker dorsal stripes ... a faint trace of mid-dorsal striping...." Dunn defined the _Hyla rubra_ group and recognized _boulengeri_, _altae_, _culex_, and _rubra_ as members. _Hyla elaeochroa_ and _staufferi_ were omitted from his key to the group in Central America. Kellogg (1932:174) compared _staufferi_ with _eximia_ and concluded that the two were probably distinct species. Stuart (1935:38) considered _altae_ to be a synonym of _culex_. Gaige (1936:293) considered _altae_ and _culex_ to be conspecific but regarded _staufferi_ as a different species. She also suggested that _staufferi_ was not related to _eximia_ but belonged to the _rubra_ group. Taylor (1952:865) and Duellman (1966a:274) considered _altae_ and _culex_ to be synonyms of _staufferi_. The only other worker besides Cope and Günther to consider _Hyla staufferi_ as a member of the _eximia_ group was Blair (1960:129), who suggested the relationship on the basis of similarities in the structure of the calls of _eximia_ and _staufferi_. Taylor (1938:421) and Smith and Taylor (1948:78) excluded _staufferi_ from the _eximia_ group on the basis of morphological characteristics. I consider _culex_ to be inseparable from _staufferi_, whereas _altae_ is recognizable as a Panamanian subspecies of _staufferi_. _Hyla staufferi staufferi_ Cope, New Combination
