description: Omobrachyiulus roseni (Verhoeff, 1921) Fig. 31 Brachyiulus roseni Verhoeff, 1921: 44-45, figs 8, 9. Chromatoiulus roseni: Lohmander 1936: 148; Lang 1959: 1791. Omobrachyiulus roseni: Vagalinski and Lazányi 2018: 100. Material examined. <i>Syntype</i> slide (gonopods, flange of male body ring 7) (ZMB 13622; Verhoeff prep. 3794). <b>Russia</b>: Republic of Adygea: 1 &amp;male; (SMNG 33579), Mount Shibaba, 21.V.2004, K. Voigtländer leg.; 4 &amp;male;&amp;male;, 1 &amp;female; (SMNG 33575), at Sakhray River, 20.V.2004, K. Voigtländer leg.; 2 &amp;male;&amp;male;, 5 &amp;female;&amp;female;, 7 juv. (SMNG 33576), same collecting data. Diagnosis. A species of <i>Omobrachyiulus</i> morphologically very similar to <i>O. zuevi</i> sp. nov. Differing from the latter species by having generally more slender and less strongly embossed gonopods, and by certain details of opisthomere structure, as follows: anterior process well-developed, linguiform, clearly visible from most aspects, vs. the same being vestigial, visible only in oral and oral-mesal views in <i>O. zuevi</i> sp. nov.; mesomeroidal lobe with a rather weakly developed apicolateral part, vs. the same being massive, nearly reaching the level of the solenomere in <i>O. zuevi</i> sp. nov.; solenomere apically only moderately enlarged, with a soft sigmoid process directed basad, vs. the same ending with a very broad, flower-like apex in <i>O. zuevi</i> sp. nov. Descriptive notes. Length 11-12 mm, height 0.8-0.9 mm. Labral setae: 16. Promentum of gnathochilarium separating both lamellae linguales almost halfway; stipites parabasally each with a row of short, stiff setae, similar to the condition seen in <i>O. ponticus</i> sp. nov. Tarsus of mid-body legs somewhat shorter than tibia and ca. 3 × as long as apical claw. Leg pair 1 parallel hooks; ventral lobes of ring 7 protruding entirely from metazona. All remaining external somatic characters as in <i>O. zuevi</i> sp. nov. Previous records from the Caucasus. <b>Russia</b>: Republic of Adygea, 40 km NE of Mount Oshten, at an influx of Belaya River [some 20 km S of Maykop] (type locality). General distribution. WCIS. Remark. The gonopods of the presently examined near-topotypic males show no differences from those seen on the syntype slide.
