description: Cyphobrachyiulus (Grusiniulus) redikorzevi (Lohmander, 1936) comb. nov. Fig. 6 Grusiniulus redikorzevi Lohmander, 1936: 148-152, figs 126-130. Grusiniulus redikorzevi: Kobakhidze, 1964: 191; 1965: 394; Vagalinski and Lazányi 2018: 78; Kokhia and Golovatch 2018: 40; 2020: 205. Material examined. 1 &amp;male;, 2 &amp;female;&amp;female; (ZIN), <b>Armenia</b>: Lake Sevan, Elenovka [Sevan], 16.VI.1927, A. Schelkovnikov leg. Descriptive notes. 20-25 labral setae. Promentum of gnathochilarium rather large, separating both lamellae linguales nearly halfway, each with four setae in a longitudinal row. Collum remarkably long, with five or six well discernible striae at posterolateral corner. Paraprocts very densely setose, without rows of shorter setae at caudal margins. Male leg pair 1 mostly parallel, slightly converging hooks, somewhat more slender compared to the usual brachyiulinine pattern. Male walking legs each with a crested adhesive pad on tibia and postfemur, tibial one very large, strongly protruding, covering the proximal half of tarsus; both pads gradually reduced towards telson, but still visible in last leg pairs; legs 3-8 additionally with a pad rudiment on femur; tarsus and tibia, on midbody legs subequal in length and 3.5-4 × as long as apical claw. Penis very small, roughly quadrangular, slightly broader than long, with barely discernible apical lobes ending with short, blunt, terminal lamellae directed distad. Gonopods (Fig. 6): Promere (Fig. 6A) ~ 1/2 the height of opisthomere, roughly quadrangular, with parallel side margins and an incised apical margin; caudal surface with a median ridge present as a massive lobe occupying most of promere’s mesal half, basally with a groove for the flagellum to hinge into, and with a lateral ridge somewhat higher and narrower than the median ridge. Opisthomere (Fig. 6B) elongated; basoposterior process vestigial, represented by a faint hump at mid-height; apicoposterior process almost straight, slightly tapering distad, ending bluntly, directed mesocaudad, with short serrate lamellae ventrally at base; solenomere very short and broad, apically forming a deep hollow surrounded by a lamella, the latter protruding higher on lateral side, with a serrate edge; a short, central, linguiform process. Previous records from the Caucasus. <b>Georgia</b>: Akhalkalaki and Borjomi (original localities). General distribution. CECA-LECA. Remarks. The species is new to the fauna of Armenia. The examined individuals have sparse and short metazonal setae, and very densely setose paraprocts, while the syntypes, according to the original description, completely lack metazonal setae and show only a sparse pilosity on the paraprocts; the type specimens are also somewhat larger. Apart from these differences, all other characters studied completely match Lohmander’s (1936) observations.
