Description based on holotype — Idiosoma longer than wide with 36 weakly barbed setae. Two pairs of anterolateral eyes, not on platelets (Figure 1a). Scutum wider than long (Figure 1a – holotype, Figure 1c – paratype) with two barbed setae AL and PL. Setae AL with expanded bases and sharply pointed; setae PL distinctly shorter than setae AL. Anterior sensillae AM very short, with relatively long setulae, placed among pouch-like structures. Posterior sensillae S nude, about twice longer than sensillae AM (Figure 1a).
Ventral surface of idiosoma bearing two very long setae 1a, short setae 3a and 10 setae behind coxae III. Setae 1b about twice longer than setae 2b and 3b. All setae nude, excluding 6 setae placed at posterior margin of opisthosoma and setae 1b-3b (Figure 1b) NDV = 46.
Gnathosoma with smooth galealae (Ga), short anterior hypostomalae (aHy) 12 µm and relatively long and smooth posterior hypostomalae (pHy). Palpfemur and palpgenu, each with one weakly barbed seta. Palptibia with 3 nude setae and bifurcated tibial claw (Figure 1d). Palptarsus with 7 nude setae (including eupathidium and solenidion); among them only eupathidium and one seta are long (Figure 1e).
Leg setal formula: Leg I: Ta – 1ω, 2ζ, 1Cp, 23 (19N, 4B); Ti – 2’, 1κ, 14 (8B, 6N); Ge – 1σ, 1κ, 8 (6B, 2N); Tf – 5B; Bf – 2B; Tr – 1B; Cx – 1B (Figures 2 a-b). Leg II: Ta – 1ω, 1ζ, 1Cp, 18 (10B, 8N); Ti – 1’, 1κ, 14 (10B, 4N); Ge – 1κ, 8 (4B, 4N); Tf – 5 (3B, 2N); Bf – 2B; Tr - 1B; Cx – 1B (Figures 2 c-d). Leg III: Ta – 1ζ, 16 (12B, 4N); Ti – 1’, 15 (11B, 4N); Ge – 8 (6B, 2N); Tf 5 (3B, 2N); Bf – 2B; Tr – 1B; Cx - 1B (Figures 2 e-f). Legs length: I 782, holotype, 774 paratype, II 782, holotype, 753, paratype, III 948 holotype (leg III broken in paratype). IP = 2512 holotype (leg III broken in paratype).
Measurements are given in Table 1.
Etymology — The species was named after the place where the holotype was collected.
Type material — The holotype and paratype larvae were collected by R. Haitlinger from herbaceous plants 6 May 2011 in Arminou n. Salamiou, Cyprus. The holotype is deposited in Museum of Natural History, Wrocław University (MNHWU), Poland. Paratype is in senior author’s collection.
Remarks — Erythraeus (Zaracarus) arminouensis n. sp. belongs to the species group with fnBf 2-2-2, TaI> 114 and TiII> 240. This group includes: E. (Z.) eleonorae Haitlinger, 1987, E. (Z.) didonae Haitlinger, 2000, E. (Z.) kurdistaniensis Khanjani and Ueckermann, 2005 (Haitlinger, 1987, 2000, Khanjani and Ueckermann, 2005). It differs from E. (Z.) eleonorae in the shorter AL (173 – 176 vs. 200 – 242), PL (80 vs. 92 – 102), AW (53 vs. 62 – 75), PW (115 – 125 vs. 140 – 167) and ISD (58 – 60 vs. 64 – 80); from E. (Z.) didonae in fD (36 vs. 26), the longer AL (173 – 176 vs. 150), 1a (113 – 115 vs. 72), 1b (108 vs. 94), TaI (125 – 128 vs. 116) and TaIII (150 vs. 136) and from E. (Z.) kurdistaniens is in the shorter AW (53 vs. 60 – 62), PW (115 – 123 vs. 140 – 150), Ti III (254 vs. 290 – 297), longer AL (173 – 176 vs. 138 – 150), 1a (113 – 115 vs. 74 – 90) and PsGd (70 – 73 vs. 50 – 64).
