The Neotropical Orb‐Weaver Genera Epeiroides, Bertrana and Amazonepeira (Araneae: Araneidae).

Abstract

For most of these spiders there is no literature other than catalog citations. Often the second citation is a misidentification, and many species, when found again, were given new names (e.g. Bertrana striolata), because making a new species is much easier than checking previous descriptions and examining their types. MATERIALS AND METHODSSpecimens from the following collections were used. I want to thank their curators for their help.AMNH

On the males of Wagneriana roraima Levi and W. yacuma Levi (Araneae, Araneidae)

“…The male palpus of Wagneriana yacuma (Fig. 4) has two lobes on the tegulum similar to that of W. {aim Levi, 1991(see LEVI 1991 fig . 76) but the apical one is longer; distinguishes by the long embolus and conductor, the…”

“…Eyes size and interdistances: AME 0.17; ALE 0.10; PMA 0.12; PLE 0.10; AME-AME 0.11; AME-ALE 0.22; PMA-PMA 0.13; PME-PLE 0.25. Abdomen with four pairs of Levi, 1991, W.jelskii (Taczanowski, 1873, W. acrosomoides (Mello-Leitao, \939), all based on both sexes, and W. roraima was reported only by females up to now.…”

“…The male palpus of Wagneriana roraima (Fig. 3) differs from that of W. silvae Levi, 1991(see LEVI 1991 fig. 186) by having a median apophysis smaller with a subapical keel, by the edge of tegulum evenly rounded, by the different shape of terminal apophysis and by the abdomen with 10 tubercles.…”

“…The males of Wagneriana roraima Levi, 1991 and W yacuma Levi, 1991 are described and illustrated for the first time. …”

New synonymies and a revalidation in the spider genera Eustala and Micrathena (Araneae: Araneidae)

“…Levi, 1985: 446 (transferred to Linyphiidae, incertae sedis); Berdondini & Whitman, 2003: 126. Remarks. The holotype was described by CAPORIACCO (1947) Diagnosis.…”
