Centrolene gorzulai (Ayarzagüena)

Centrolenella gorzulae Ayarzagüena, 1992: 19 , fig. 3E (preserved holotype in dorsal view), fig. 4 (palmar view of hand). Holotype MHNLS 11221 [8] from Cerro Auyantepuy-Centro , Estado Bolívar, Venezuela (5 ° 569N, 62 ° 349W), 1850 m, collected August 26, 1983 by S. Gorzula.

Centrolenella auyantepuiana Señaris and Ayarzagüena , ‘‘1993’’ [1994]: 122, fig. 1 (hand and foot) + sound spectrogram. Holotype MHNLS 12482 (8) from sector centro oeste del Auyantepui , Estado Bolívar, Venezuela (5 ° 549N, 62 ° 389W), 1850 m, collected June 5, 1992 by J. Ayarzagüena.

Cochranella auyantepuiana: Myers and Donnelly, 1997: 16 (new combination).

Hyalinobatrachium auyantepuiana: Ayarzagüena and Señaris , ‘‘1996’’ [1997]: 12–13 (new combination).

Hyalinobatrachium auyantepuianaum: Myers and Donnelly, 1997: 71 (correction of spelling).

This species is known only from Auyantepui, based on a total of four specimens, one collected by Gorzula in August 1983 and three by Ayarzagüena in June 1992. See Señaris and Ayarzagüena (2005: 79–84, 299) for an account of this seemingly endemic species.

Hyalinobatrachium crurifasciatum Myers and Donnelly

Hyalinobatrachium crurifasciatum Myers and Donnelly, 1997: 9 , figs. 7–10 (dorsal views of preserved holotype and paratopotype, drawings of hand and foot in palmar and plantar views, sound spectrographs and waveforms). Holotype AMNH A-131329 (ad. 8) from forested stream at north base of Pico Tamacuari , 1160–1200 m, Sierra Tapirapecó, Amazonas, Venezuela (1 ° 139N, 64 ° 429W), obtained March 11–17, 1989 by C. W. Myers, M. A. Donnelly, and J. W. Daly. Myers and Donnelly, 2001: 20, fig. 13A (eye of holotype), 22, fig. 15 (replacement drawings of hand and foot of holotype).

C [entrolenella] sp. ( cf. orientalis ): Señaris and Ayarzagüena, ‘‘1993’’ [1994]: 124, from sector centro-oeste del Auyán-tepui (5 ° 549N, 62 ° 389W), 1850 m, June 1992 [two specimens fide Señaris and Ayarzagüena, 2005: 302].

Señaris and Ayarzagüena (2005) have shown that Hyalinobatrachium crurifasciatum is unexpectedly widespread in the Venezuelan Guayana, but that it has been repeatedly misidentified as Centrolenella orientalis or Hyalinobatrachium orientale . For synonymy and a thorough species account, with an abundance of illustrations, see Señaris and Ayarzagüena (2005: 161–172, 274, 302).

The two specimens of Hyalinobatrachium crurifasciatum from Auyantepui were collect- ed at 1850 m, in June 1992, in sympatry with H. taylori and Centrolene gorzulai according to Señaris and Ayarzagüena (‘‘1993’’ [1994]: 124; 2005: 251). (However, slightly different coordinates are given for the three species on Auyantepui [Señaris and Ayarzagüena, 2005: 299, 302, 305).

Figure 110a in Señaris and Ayarzagüena (2005: 163) suggests the possible presence of a bulla in the webbing between fingers III and IV. We described this shallow bubblelike structure in H. crurifasciatum and the morphologically similar H. eccentricum (Myers and Donnelly, 2001: 22, figs. 12, 15), but the taxonomic distribution and significance of this easily overlooked structure remains to be determined.
