Armascirus fendai Kalúz & Vrabec, 2013

Description. Deutonymph (1 specimen measured)—body length 514, width 316. Body of deutonymph has smaller dimensions as in female, less sclerotization except for palp, larger reticulation on hysterosomal median shield and smaller genital valves bearing three simple setae each.

Dorsum. Anterior trichobothrium 258, posterior trichobothrium 347 long, distance between bases of vi–vi and sce–sce 29 and 185, respectively. Propodosoma separated from hysterosoma by fine striae. Hysterosoma with hysterosomal median shield 78 long and 91 wide and a pair of lateral reticulate platelets 29 long and 11 wide. Six pairs of tactile dorsal setae present on hysterosoma; c2, c1–h1. Short setae c1 12, c2 6, d1 15, e1 17, f1 21 and h1 23 long. Distance between bases of setae c1–c1 120, c2–c2 231, d1–d1 63, e1– e 1 6, f1– f1 57 and h1–h1 37.

Venter. Setal formula of coxae I–IV: 3–2–3–3 sts. Venter of hysterosoma with a pair of simple centro-medial setae on longitudinally striated integument between coxae III, and with 3 pairs of hysterogastral setae on transversally striated integument arranged anteriorly to genital plates. Three simple setae on each of weakly sclerotized genital valves, setae equal in length. Each of two pairs of para-anal setae situated on small platelet, and a pair of anal setae present on soft tegument close to anal opening.

Gnathosoma . Palp 251 long, setation as in female. Palpal chaetotaxy as follows: trochanter—bare, basifemur—1 sts; telofemur—1 ap (17 long), 1 ap (21), 1 spls; genu —1 ap (50), 2 spls, 2 sts; tibiotarsus—1 spls, 4 sts. Chelicera slender and 154 long with a pair of distal setae. Subcapitulum with two pairs of short adoral setae and four pairs of hypognathal setae (hg); setae hg1 15, hg2 21, hg3 11 and hg4 43 long.

Legs. Chaetotaxy I–IV as follows: coxae 3–2–3–3 sts, trochanters 1–1–2–1 sts; basifemora 2–2–1–0 sts; telofemora 4–4–4–4 sts; genu I—1 asl, (1 sts,1 mst), 5 sts; genu II—1 asl, 6 sts; genu III—6 sts; genu IV—6 sts; tibia I—(1 asl, 1 mst), 5 sts; tibia II—1 asl, 5 sts; tibia III –1 bsl, 6 sts; tibia IV—1 smooth T, 4 sts; tarsus I—1 fam, 1 asl, 1 tsl, 10 sts; tarsus II—1 bsl, 1tsl, 8 sts; tarsus III—9 sts; tarsus IV—7 sts.

Length of leg segments I–IV (coxa and trochanter not measured): Basifemur 62–69–66–77; Telofemur 46–39–34–36; Genu 28–29–34–43; Tibia 39–31–49–51; Tarsus 136–117–135–134.

Material studied. N—Slovakia, High Tatras Mts., Vyšné Hágy vicinity (N–49˚07′20″, E–20˚06′32″), 1175 m a.s.l., mountain meadow, 11 July 2008, 1 deutonymph collected from grass rhizosphaera. Material collected by S. Kalúz.
