Material examined
Holotype ♀ and paratype 1 ♂ juv. from IZ PAN with museum label ‘ Armenia: Elenovka, ad lacum Goktsha, 9.VI. leg. G. Horwath’ (Figure 1f, modern name Sevan Town on Sevan Lake) and original label ‘ Armenia ♀, ♂ juv. Bessarabia’ (Figure 1g); 1♂ 20 juv. (ZMMU), ARMENIA, Gegharkunik Province, Sevan Lake, env. of Tsovagyugh Town, 40.615°N 44.968°E, 1920 m, lake shore, in dry collective fruits (= inflorescence) of Astragalus sp., 8 May 2021 (Y.M. Marusik).
Note
Holotype ♀ (Armenia) and paratype subadult male (Bessarabia) are from very widely separated localities (ca. 1500 km).
Brief description
Holotype female. General appearance as in Figure 1a–b, h. Total length 3.0. Carapace 1.25 long, cephalic part 0.83 wide, thoracic part 0.95 wide. Leg length as shown in Table 1.
Epigyne as in Figure 1c–e.
Topotype male. General appearance as in Figure 2d, g–h. Total length 2.63. Carapace 1.25 long, cephalic part 0.63 wide, thoracic part 1.0 wide. Leg length as shown in Table 2.
Palp as in Figure 2a–c.
Comments
The endogyne of the holotype female of D. ignobilis is undistinguishable from that of D. arundinacea. The adult male specimen collected about 10 kilometres from the type locality has no distinct differences in the palp from that of D. arundinacea, and therefore the two names are synonymised here. The slight apparent differences between the male palps of specimens from Armenia (Figure 2a–c) and Yakutia (Figure 2d–e) are caused by different positions of the palps during photography.
Distribution
Dictyna arundinacea has a circum-Holarctic range and is known across the whole Palaearctic from Iceland to Kamchatka (Marusik et al. 2000), and throughout the Nearctic from Alaska (GenBank accession nos: KU874826, KU874827) to Newfoundland (Paquin et al. 2010). This species is also known from across the Caucasus, including Armenia (Otto 2022).
