Gnophopsodos ravistriolaria ( Wehrli, 1922)

(adults Pl. 1, Figs 1 View FIGURE 1 , 2; male gen. Pl. 2, Fig. 3, female gen. Pl. 2, Fig. 4)

Gnophos ravistriolaria Wehrli, 1922 , Deutsche Entomologische Zeitschrift Iris, 36: 23, pl. 1, fig. 23, pl. 2, fig. 35, 51. Type locality:

Russia / Mongolia, Sayan Mountains, Munko–Sardyk, 3400 m.

Material examined. Holotypes of both G. ravistriolaria ravistriolaria and G. ravistriolaria pantherinus , and 15 paratypes of G. r. pantherinus (details in Erlacher & Erlacher, 2016). The following material of G. ravistriolaria ravistriolaria has recently been received: Russia: 2♂, West Buryatia, 24 km N Sagan Shuluta, River Irkuta , 51°(53–56)’36’’N / 100°(43– 46)’41’’E, 1850–1950 m, 14.–18.vii.2015, ad luc., leg. A. Steidel and O. Czadec, gen. prep. SE–728 (adult Pl. 1, Fig. 1 View FIGURE 1 ) and SE–742 (male gen. Pl. 2, Fig. 3); 1♀, same data, gen. prep. SE–741 (adult Pl. 1, Fig. 2; female gen. Pl. 2, Fig. 4), MRJ .

Description of Gnophopsodos ravistriolaria ravistriolaria .

Adults (Pl. 1, Figs 1 View FIGURE 1 , 2): Wings: Wingspan: 27–30 mm (♂), 26 mm (♀); ground color yellowish, erratically and densely scattered with darker scales; wing pattern with medial lines and discal spot indistinct or mingled with background; underside pale and dull.

Male genitalia (Pl. 2, Fig. 3): for a detailed description see Erlacher & Erlacher (2016).

PLATE 1. Adults of Gnophopsodos ravistriolaria . 1: male; 2: female. Undersides of specimens are denoted by ‘*’. Scale bar: 10 mm.

Female genitalia (Pl. 2, Fig. 4): Papillae anales densely covered with strong setae; posterior apophysis longer than anterior apophysis; antrum bulbously distended, sclerotized, antrum length 0.8 mm, width 0.45 mm, ostium area dorsally bulging and folded, internal portion of the partially everted antrum well sclerotized and visible halfway down the antrum; corpus bursae hyaline; total length of female genitalia: 3.19 mm.

Diagnosis. In the female genitalia, G. ravistriolaria resembles G. puengeleri ( Bohatsch, 1910) and G. sabine Erlacher & Erlacher, 2016 (detailed description of the two latter species in Erlacher & Erlacher (2016)). However, in G. puengeleri the antrum is smaller than in G. ravistriolaria , and in G. sabine the antrum is more pear-shaped and the internal portion is totally sclerotized.

Biology. The three examined specimens were captured in the river valley where the river Sasar enters the main river Irkut ( Fig. 1 View FIGURE 1 ). Adjacent moraine slopes consisted of rubble debris of various rocks, overgrown with mostly crippled Larix trees and thick bush vegetation consisting of Spiraea sp., Betula nana , Alnus viridis , Salix spp., Corylus avellana , Lonicera altaica , Grossularia reclinatum and yellow-blossomed Dasiphora fruticosa . Open slope areas were swampy, covered with Sphagnum , Vaccinium , Orchidaceae and others. Moist sites of the river valley were vegetated with Rheum , more open and dry sites with a large-growing Astracantha species, Geranium and Anemone species and others. The river bank as well as the plateau was overgrown with Anemone , Geranium , Astragalus and grasses (A. Steidel pers. comm.).
