Derka, Tomáš, Figueroa, J. Manuel Tierno De & Čiampor, Fedor, 2019, Enderleina preclara Jewett, 1960 (Plecoptera, Perlidae), from the Venezuelan Guayana-A description of a putative female, nymph and egg, Zootaxa 4585 (2), pp. 332-342 : 341

Enderleina preclara type locality

Jewett (1960) described the type locality of E. preclara as follows: “ Holotype male, Mt. Roraima, AMAZONAS, alt. 6,900 ft., Rondon, XII-5-27 (AMNH)” and attributed this specimen to Brazilian fauna. However, according to data from the label, it is certain that the holotype was collected during the Lee Garnett Day Expedition to Roraima-tepui in 1927, which was organized by the American Museum of Natural History, New York. It was led by Mr. G. H. H. Tate, who was accompanied by T. D. Carter, both from the American Museum's Department of Mammals, and by Tate's brother, Mr. G. M. Tate, who served as a volunteer. The expedition approached Roraima-tepui from Brazil by way of the Rio Branco. Collections in the Roraima-tepui district began at Paulo camp on October 27, 1927 and continued until January 9, 1928 ( Chapman 1931). From this information and from the photograph ( Fig. 8 in Chapman 1931), we infer that “Rondon” on holotype label, means Rondon camp, described, photographed and mapped in Chapman (1931). The site is located at the mountain talus between the current Roraima-tepui base camp and the southwestern vertical mountain wall at the unique footpath still leading to Roraima-tepui summit. This area is completely within Venezuela ( Figs. 1–3 ). Therefore, the type specimen of E. preclara originated in Venezuela and not Brazil, as erroneously stated by Jewett (1960). However, the borders of Brazil, Guyana, and Venezuela meet at Roraima-tepui, so we can assume that the species should occur in all three countries. Our material from the talus of Kukenán-tepui was collected only 5 km from the type locality ( Fig. 3 ). Additionally, the coloration of collected females is similar to the coloration of the male E. preclara described by Jewett (1960). Therefore, the collected specimens can be attributed with high probability to E. preclara and thus we have described above the unknown nymph, female and egg of E. preclara .
