The Cloud Forest Colostethus (Anura, Dendrobatidae) of a Region of the Cordillera Occidental of Colombia

On the Identities of Colostethus inguinalis (Cope, 1868) and C. panamensis (Dunn, 1933), with Comments on C. latinasus (Cope, 1863) (Anura: Dendrobatidae)

“…Ear terminology follows Lynch and Duellman (1997). Diagnostic characters are derived from Edwards (1974), Myers et al (1991), Coloma (1995), Grant et al (1997), Grant and Castro-Herrera (1998), and Grant and Rodríguez (2001 Cochran, 1966: 65;Cochran and Goin, 1970: 59 (part). Colostethus inguinalis -Savage, 1968: 751 (part).…”

“…The nonmonophyly of Colostethus has been recognized for decades (Lynch, 1982), and the naming of Ameerega, Aromobates, Epipedobates, Mannophryne, and Nephelobates has merely exacerbated the problem Coloma, 1995;Meinhardt and Parmelee, 1996;Grant et al, 1997;Grant and Castro-Herrera, 1998). Colostethus is also the most diverse genus of dendrobatids, with 138 named species recognized currently.…”

“…Generally, Colostethus is regarded as a group of convenience for all dendrobatids that cannot be referred to one of the other genera (e.g., Grant and Rodríguez, 2001). Detailed investigations of several new species of Colostethus have led to the discovery of novel morphological characters that help elucidate phylogeny (Coloma, 1995;Grant et al, 1997;Grant and Castro-Herrera, 1998;Grant and Rodríguez, 2001;Myers and Donnelly, 2001;Caldwell et al, 2002a), and molecular studies are accumulating data rapidly (e.g., Santos et al, 2003;Vences et al, 2003a), but to date progress has been limited. Molecular evidence for the monophyly of Mannophryne and Nephelobates was presented by La Marca et al (2002) and Vences et al (2003a), but the relationship of those genera to other dendrobatids is unclear.…”

“…He did not note the occurrence of the median lingual process, although it is present in several of these species. Grant and Castro (1998) proposed the Colostethus ramosi group based on the occurrence of a patch of black, apparently glandular tissue on the ventral and medial surfaces of the distal extreme of the upper arm, just proximal to the elbow (referred to by Grant and Castro as the black arm band). This group presently includes C. cevallosi, C. exasperatus, C. fascianiger, C. lehmanni, C. ramosi, and C. saltuarius (Grant and ArdilaRobayo, 2002), but this character-state also occurs in C. anthracinus and an undescribed species from the slopes of the Magdalena valley, Colombia (T. Grant, personal obs.).…”

“…Lynch, 1982a;J.D. Lynch and Ruiz-Carranza, 1982), and the naming of Aromobates, Epipedobates, Mannophryne, and Nephelobates has merely exacerbated the problem (Kaiser et al, 1994;Coloma, 1995;Meinhardt and Parmalee, 1996;Grant et al, 1997;Grant, 1998;Grant and Castro-Herrera, 1998). Molecular evidence for the monophyly of Mannophryne and Nephelobates was presented by La Marca et al (2002) and Vences et al (2003b), but the relationships of those genera to other dendrobatids are unclear.…”
