Solodovnikov and S. Tarasov leg. Diagnosis. A species of <i>Omobrachyiulus</i> closely resembling <i>O. divaricatus</i> and <i>O. unugulis</i> sp. nov. by the general shape of both pro- and opisthomere. Differs from these two species mostly by the bulging pillow-shaped, rather than antero-caudally strongly flattened, apical outgrowth of the basoposterior process, as well as by the very large (both long and broad) epiproct. Previous records from the Caucasus. <b>Georgia</b>: Tbilisi; Borjomi (original localities); Zeskho near Lentekhi (Kobakhidze 1965); AR Abkhazia, at the mouth of Kelassuri River [S of Sukhumi], passage cave (type locality of <i>O. m. abchasicus</i>); Klych River valley (Kobakhidze 1965). General distribution. CAUC. Remarks. The species is new to the fauna of Russia. The subspecies <i>O. m. abchasicus</i> was described by Lohmander (1936) from near Sukhumi, AR Abkhazia. The author emphasised the high similarity between the typical <i>O. macrourus</i> and his newly described subspecies, but failed to present a diagnosis to distinguish between the two forms. The sole diagnostic character than can be inferred from the original description of <i>Omobrachyiulus abchasicus</i> is the presence of a small conical lobe distally at the apical outgrowth of the basoposterior process (z in figs 111, 113), that lobe being absent from the typical form. Considering the slight to moderate shape variations in the apical outgrowth in some of the examined specimens originating from different parts of the species’ distribution range, <i>O. m. abchasicus</i> does not look like a viable taxon. However, in the absence of material from Abkhazia we prefer to refrain from a formal synonymisation with the typical <i>O. macrourus</i>.
