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 View Figure 1 , modern name Sevan Town on Sevan Lake ) and original label ‘ Armenia ♀, ♂ juv. Bessarabia’ ( Figure 1g View Figure 1 ); 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). GoogleMaps

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 View Figure 1 . 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 View Table 1 .

Epigyne as in Figure 1c–e View Figure 1 .

Topotype male. General appearance as in Figure 2d, g–h View Figure 2 . 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 View Table 2 .

Palp as in Figure 2a–c View Figure 2 .

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 View Figure 2 ) and Yakutia ( Figure 2d–e View Figure 2 ) 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 View Materials , KU874827 View Materials ) to Newfoundland ( Paquin et al. 2010). This species is also known from across the Caucasus, including Armenia ( Otto 2022).
