A mountain of millipedes VII: The genus Eviulisoma Silvestri, 1910, in the Udzungwa Mountains, Tanzania, and related species from other Eastern Arc Mountains. With notes on Eoseviulisoma Brolemann, 1920, and Suohelisoma Hoffman, 1963 (Diplopoda, Polydesmida, Paradoxosomatidae) Author Enghoff, Henrik text European Journal of Taxonomy 2018 2018-06-19 445 1 90 journal article 10.5852/ejt.2018.445 5dfd4ff4-6c8b-47f4-9aa7-0f6b1b2af967 1489598 852A3F68-B728-413A-B12E-56F306D56C35 The iuloideum group Diagnosis Species of Eviulisoma in which sternum 6 is deeply excavated with unlobed margins, the gonopod acropodite has a separate basal ʻfemoriteʼ part, there is no intermediate acropodital process and the solenophore is a large, unrolled sheet without apical lobes. Included species: E. iuloideum ( Verhoeff, 1941 ) E. articulatum sp. nov. This group corresponds to the genus Himatiopus Verhoeff, 1941 . The description of E. iuloideum by Verhoeff (1941) is quite good, and the similarity with E. articulatum sp. nov. is obvious. An examination of the type material of Himatiopus iuloideus confirmed the similarity but also confirmed that the two species are indeed different. E. lanceolatum Attems, 1953 (Congo) also seems to have an articulated acropodite, but the solenophore is quite different ( Jeekel 2003 ); hence, E. laceolatum is not regarded as a member of the iuloideum group.
