Omobrachyiulus hortensis (Golovatch, 1981) Fig. 17A Chromatoiulus hortensis Golovatch, 1981: 110-112, figs 14-26. Megaphyllum hortense: Talikadze 1984: 143. Omobrachyiulus hortensis: Vagalinski and Lazányi 2018: 97; Kokhia and Golovatch 2018: 41; 2020: 206. Material examined. Georgia: 2 ♂♂, 2 ♀♀ (ZMUM), NE of Poti, Chaladidi, Alnus, Quercus, Fraxinus forest on swamp, in litter, 13.IV.1983, SIG leg.; 1 ♂, 1 ♀ (ZMUM), AR Abkhazia, Sukhum District, Nizhnyaya Yashtukha, forest nursery, 29.III.1985, А. Markossian; 1 ♂, 2 juv. (ZMUM), same place, tobacco plantation, 16.VI.1980 and 25.VII.1980, А. Markossian. Diagnosis. A species of Omobrachyiulus most similar to O. armatus sp. nov. by the promere significantly outreaching the opisthomere, the latter possessing a massive lobe-like basoposterior process forming two distinct corners, a basal and a distal one, and having a micro-spiculate mesal side, and a unipartite solenomere with a slender rod-like ending. Differs from O. armatus sp. nov. mainly by the clearly tripartite apical outgrowth of the basoposterior process, consisting of a mesal lamellar, a median fan-shaped, and a lateral spiniform part, vs. that same outgrowth being broad, unipartite, collar-shaped and dentate at the margins in the latter species. Descriptive notes. Promere rather slender, significantly outreaching the opisthomere, with a narrowly rounded apex; distolaterally micro-papillate. Opisthomere (Fig. 17A) short and stout; basoposterior process massive, with a micro-spiculate mesal side, and an apical outgrowth consisting of three parts: a mesal and a median one, both being fan-like and partly fused, and a lateral spine-like one (very similar to aol in Fig. 17C); an anterior process absent or vestigial; mesomeroidal lobe moderately developed; mesal side with a relatively large, but not freely protruding lobe (presumably gonocoxal gland), and a very large and deep anteromesal sinus; two rows of very long, erect, spiniform filaments parabasally at flagellum channel; solenomere unipartite, very fine and rod-like. Previous records from the Caucasus. Georgia: AR Abkhazia, Sukhum Botanical Garden (type locality). General distribution. COLC-SWGC.
