Six new species of the widespread Brazilian millipede genus Eucampesmella (Polydesmida: Chelodesmidae)

ABSTRACT This study concerns the diplopod genus Eucampesmella Schubart, 1955, widespread in Brazil. After this work, the genus includes 12 valid species, and three incertae sedis: E. pugiuncula (Schubart, 1946), E. brunnea Kraus, 1959 and E. schubarti Kraus, 1957. The type-species, Eucampesmella tricuspis (Attems, 1931), is redescribed based on the holotype, and the following six new Brazilian species are added: Eucampesmella macunaima sp. nov. from the states of Rondônia, Pará, and Piauí; E. capitu sp. nov. from the states of Piauí and Paraíba; E. brascubas sp. nov. from the state of Sergipe; E. iracema sp. nov. from the state of Pernambuco; E. pedrobala sp. nov. from the state of Ceará; and E. lalla sp. nov. from the state of Rio Grande do Norte. Furthermore, E. lartiguei ferrii (Schubart, 1956) is recognized as a junior synonym of E. lartiguei lartiguei (Silvestri, 1897), which also had its status changed, and E. sulcata (Attems, 1898) is revalidated, prevailing under the name Leptodesmus tuberculiporus Attems, 1898. In addition, drawings, diagnoses, and distribution maps for all species of the genus are provided.

摘要 本研究针对广布于巴西的倍足纲Eucampesmella属（Schubart, 1955）展开。经本研究修订后，该属共计包含12个有效物种，另有3个分类地位未定类群：E. pugiuncula（Schubart, 1946）、E. brunnea Kraus, 1959与E. schubarti Kraus, 1957。模式种Eucampesmella tricuspis（Attems, 1931）基于正模标本完成重新描述，同时新增6个巴西新种：产自朗多尼亚州、帕拉州及皮奥伊州的Eucampesmella macunaima sp. nov.；产自皮奥伊州与帕拉伊巴州的E. capitu sp. nov.；产自塞尔希培州的E. brascubas sp. nov.；产自伯南布哥州的E. iracema sp. nov.；产自塞阿拉州的E. pedrobala sp. nov.；以及产自北里奥格兰德州的E. lalla sp. nov.。此外，E. lartiguei ferrii（Schubart, 1956）被认定为E. lartiguei lartiguei（Silvestri, 1897）的次异名，后者的分类地位亦得到修订；而E. sulcata（Attems, 1898）的分类地位得以恢复，其有效学名为Leptodesmus tuberculiporus Attems, 1898。本研究还为该属所有物种提供了形态绘图、鉴定特征及分布地图。
