摘要

Pamphobeteus ultramarinus Schmidt, 1995 和 P. vespertinus (Simon, 1889) 的模式标本被重新描述。首次描述了 P. lapola Sherwood, Gabriel, Brescovit & Lucas, 2022 的雄性。描述了六个新种：和来自巴西的 P. gangotenai Cisneros-Heredia、Peñaherrera-R、新种，P. jamacoaque Peñaherrera-R., Cisneros-Heredia., León-E., Sherwood, Gabriel, Brescovit & Lucas sp、P. lasjuntas Peñaherrera-R., Cisneros-Heredia., León-E., Sherwood, Gabriel, Brescovit & Lucas sp、和厄瓜多尔的 P. skis León-E., Peñaherrera-R., Cisneros-Heredia, Sherwood, Gabriel, Brescovit & Lucas sp.我们首次报告了 Pamphobeteus Pocock, 1901 存在第三类荨麻状刚毛。我们对胫骨骨干形态进行了新的解释，并对所有已知雄性同源种的颚球形态进行了比较。P. antinous Pocock, 1903、P. crassifemur Bertani, Fukushima & Silva, 2008、P. lapola 和 P. urvinae Sherwood, Gabriel, Brescovit & Lucas, 2022 的新分布和/或博物馆记录。Pamphobeteus petersi Schmidt, 2002 被绘制成插图，并根据上颚鳞茎形态转入 Megaphobema Ausserer, 1875 属，并被提议作为 Megaphobema velvetosoma Schmidt, 1995 的初级异名。根据生殖器、股器和缢缩器的形态，发现目前归入 Megaphobema 属的两个哥斯达黎加种位置错误，并将其转入 Abdomegaphobema 属，从而产生了新组合 Abdomegaphobema mesomelas (O. Pickard-Cambridge, 1892) comb.

Pamphobeteus Pocock, 1901: redescriptions, new species and records, description of a missing sex, with taxonomic notes and changes in Megaphobema Pocock, 1901 (Araneae: Theraphosidae)

The type material of Pamphobeteus ultramarinus Schmidt, 1995 and P. vespertinus (Simon, 1889) are redescribed. The male of P. lapola Sherwood, Gabriel, Brescovit & Lucas, 2022 is described for the first time. Six new species are described: P. amazonas Sherwood, Gabriel, Peñaherrera-R., Cisneros-Heredia., León-E., Brescovit & Lucas sp. nov. from Brazil, and P. gangotenai Cisneros-Heredia, Peñaherrera-R., León-E., Sherwood, Gabriel, Brescovit & Lucas, sp. nov., P. jamacoaque Peñaherrera-R., Cisneros-Heredia., León-E., Sherwood, Gabriel, Brescovit & Lucas sp. nov., P. lasjuntas Peñaherrera-R., Cisneros-Heredia., León-E., Sherwood, Gabriel, Brescovit & Lucas sp. nov., P. matildeae Sherwood, Gabriel, Peñaherrera-R., Cisneros-Heredia., León-E., Brescovit & Lucas sp. nov., and P. skis León-E., Peñaherrera-R., Cisneros-Heredia, Sherwood, Gabriel, Brescovit & Lucas sp. nov. from Ecuador. We report, for the first time, the presence of Type III urticating setae in Pamphobeteus Pocock, 1901. New interpretations of tibial apophysis morphology are presented, alongside a comparison of the palpal bulb morphology of all known male congeners. New distribution and/or museum records are made for P. antinous Pocock, 1903, P. crassifemur Bertani, Fukushima & Silva, 2008, P. lapola, and P. urvinae Sherwood, Gabriel, Brescovit & Lucas, 2022. Pamphobeteus petersi Schmidt, 2002 is illustrated and transferred to the genus Megaphobema Ausserer, 1875, based on palpal bulb morphology, and proposed as a junior synonym of Megaphobema velvetosoma Schmidt, 1995 syn. nov. Two Costa Rican species currently housed in Megaphobema are found to be misplaced, based on genital, femoral, and stridulation organ morphology, and are transferred to Abdomegaphobema gen. nov., Thus creating the new combinations Abdomegaphobema mesomelas (O. Pickard-Cambridge, 1892) comb. nov. and Abdomegaphobema peterklaasi (Schmidt, 1994) comb. nov.
