Arachnologische Mitteilungen 57
Arachnologische Mitteilungen / Arachnology Letters 57: 87-88 Karlsruhe, April 2019 Examination of the extensive spider material collected by the Swiss arachnologist Antoine Senglet in Italy and Greece re- vealed a new species of Agyneta Hull, 1911 described here in the present paper. Material and methods This paper is based on material kept at the Muséum d’histoire naturelle de Genève, Switzerland (MHNG). Specimens preserved in 70% ethanol were studied using a MBS-9 ste- reomicroscope. The sequence of leg segment measurements is as follows: femur + patella + tibia + metatarsus + tarsus. All measurements are given in mm. The terminology of the copulatory organs mainly follows that of Merrett (1963) and Saaristo (1971, 1973). Abbreviations used in the text and figures E = embolus, EP = embolus proper (after Saaristo 1971), L = lamella characteristica, Mt = metatarsus, PH = pit hook (after Saaristo 1973), R = radix, T = tooth, TmI = position of me- tatarsal trichobothrium on leg I, ZMMU = Zoological Muse- um of the Moscow State University, Moscow, Russia.

Diagnosis. Agyneta inermis spec. nov. is very similar to A. iranica Tanasevitch, 2011, known from Iran (Tanasevitch 2011) and Turkmenistan (new data). The new species is dis tinguished by certain details of the structure of the lamella characteristica (Figs 7-10 vs. Fig. 11), by the shallow hollow on the apex of the palpal tibia (Fig. 3 vs. Fig. 13), as well as by the absence of a basal tooth at the base of the embolus (Fig. 6 vs. Fig. 12, tooth marked as “T”). Etymology. The specific epithet is a Latin adjective meaning “unarmed”, referring to the absence of a tooth at the base of the embolus. Description. Male (holotype). Total length 1.80. Pro- soma 0.75 long, 0.55 wide, brown with dark mar- gins. Chelicerae 0.33 long, weak. Legs pale brown. Leg I 3.07 long (0.80+0.23+0.78+0.73+0.53); IV 2.88 long (0.78+0.20+0.75+0.70+0.45). Opisthosoma 0.93 long, 0.60 wide, dark grey. Chaetotaxy: each tibia with two dorsal spines; Mt I–IV spineless. Metatarsus IV without a trichobothrium. TmI 0.31. Palp (Figs 1-10): tibia short, with a small, poin- ted, dorso-prolateral tubercle and a short, wide, keel-shaped, retrolateral outgrowth. Cymbium without posterodorsal apo- physis. Paracymbium with well-developed pockets, except for apical one (see Saaristo 1973). Lamella characteristica a narrow band expanded at base, uncinate apically. Embolus without teeth at its base. Female. Unknown. Variation. As the palps in both type specimens seem to be identical, no variation in this structure has been found. Distribution. The species is known from only two localities, one each in Italy and Greece.

Tanasevitch doi: 10.30963/aramit5716 Abstract. A new species, Agyneta inermis spec. nov. , is described, based on two males from Italy and Greece. The new species is very similar to the Iranian A. iranica Tanasevitch, 2011 (first record for Turkmenistan), but differs in structural details of the male palp, primarily by the absence of a tooth at the base of the embolus.

Eine neue Agyneta aus Italien und Griechenland (Araneae: Linyphiidae). Eine neue Art, Agyneta inermis spec. nov. , wird auf Basis zweier Männchen aus Italien und Griechenland beschrieben. Die neue Art ist der iranischen A. iranica Tanasevitch, 2011 (Erstnachweis für Turkmenistan) sehr ähnlich, unterscheidet sich aber in Details des männlichen Palpus, besonders durch das Feh- len eines Zahns an der Embolus-Basis.
