The neotropical Froschlurch Scinax manriquei ( Syn. : Scinax flavidus La Marca, 2004) belongs to the subfamily scinax (Scinaxinae) within the family of tree frogs .

Dispute over priority

The species was described twice independently in quick succession in 2004 . The manuscript by Enrique La Marca , in which the new species was described under the scientific name Scinax flavidus , appeared in a new journal published by La Marca itself entitled Herpetotropicos , on the cover of which the date March 1, 2004 was noted. The description of the working group around César Luis Barrio-Amorós under the name Scinax manriquei was much more detailed, but only appeared on March 26, 2004 in the Journal of Herpetology . The two were listed as different species until 2007, when La Marca pointed out the same yellow color and different characteristics and declared the two species described as synonymous. Thus, the naming Scinax flavidus would have had priority over Scinax manriquei , which La Marca also highlighted in 2007 in the third year of its magazine Herpetotropicos , which was published at the time . The group around Barrio-Amorós found, however, that the publication of La Marcas magazine on March 1st could not be verified. The envelope was not printed until the end of May 2004; specimen copies did not arrive at the libraries until months later. Even if the content of the magazine, whose pages are only marked “March 2004”, had already been published in advance, it would have to be classified according to the rules of the ICZN with a publication date of March 31st. The priority of the first description and the scientific name of the frog have therefore been changed.

description

Scinax manriquei differs from other species of the genus by its striking yellow coloration (especially in males), two dorsolateral stripes and unpatterned upper sides of the thighs. Barrio-Amorós et al. (2004) give a head-trunk length of 27.7 ± 1.7 mm for males (n = 18) and of 31.1 ± 1.1 mm for females (n = 4). Photos and drawings can be found at La Marca (2004) and La Marca (2007)

The species is placed in the Scinax ruber clade within the genus Scinax .

Distribution and way of life

The species occurs in the Andes of Venezuela and Colombia . In Venezuela, it is known from a single finding near Bramón at 600 m above sea level. Otherwise it occurs between 1000 and 1700 m above sea level; in Venezuela on both sides of the Táchira plain and widespread on the Cordillera de Mérida , a foothills of the Andes. In Colombia there are two sites in mountain rainforests near the border with Venezuela (1400–1500 m above sea level).

Scinax flavidus has been found in anthropogenically modified vegetation and artificial waters as well as remains of primary forest . One individual was found in a bromeliad 2 m above the ground, but no reproduction was detected and the spawning waters of this species remain unknown.

Danger

The IUCN lists the species under the name Scinax flavidus as "not endangered" ( Least Concern ). Their widespread distribution and the fact that the total population is estimated to be large enough and that the species was found in changing habitats justify this. The processors consider it unlikely that stocks of the species can decline quickly enough to justify a higher endangerment level. In addition, the species occurs in the "Chorro El Indio" national park in Venezuela. However, the exact abundance and population trend, as well as the main sources of endangerment, are unknown.
