SUPERFAMILIA HESPERIOIDEA Latreille, 1809 (= Grypocera Karsh, 1893)

FAMILIA HESPERIIDAE

"Skippers", the butterflies of small, rarely of intermediate size. The antennal club is rather smooth, hooked in some genera. The head is wide (its width exceeding the length), with widely set eyes; being covered with dense hairs, the head seems even more wide. The thorax is also wide due to the well developed wing muscles which allow a swift and impetuous flight being a characteristic of these butterflies. The fore wings are triangular in shape. All the legs are equally developed.

The larvae are naked, short, spindle-shaped; they live in the leaves fastened with silken threads, hibernate and pupate in loose silken shelters on the ground or among the leaves of foodplants.

The world fauna contains about 3600 species of skippers, mostly distributed in the tropics and subtropics. There are about 100 species in the temperate Eurasia and 53 in the Asian Russia.

FLIGHT PERIOD: middle July/middle August.

PREIMAGINAL PHASES: studied in Japan (Fukuda et al., 1984). Foodplant: Kalopanax septemlobum (Araliaceae). Eggs: usually inside old larval dwelling on the foodplant. The larva hibernates in the second instar in a peculiar cocoon on the bark of the food tree, later constructs a dwelling in the leaves of the foodplant. The last instar larva is greyish-brown with several lengthwise light lines, the head is orange-red. Pupa: light-brown with dense white suffusion, in a loose silken shelter on the foodplant.

PECULIAR TRAITS OF IMAGO: F.w.l.: 20-25 mm. The wings are brown, the fore wing underside has yellow spots.

GENUS SATARUPA Moore, 1866.

Type species: Satarupa gopula Moore, 1865.

An East- and South-Asian genus with 7 species.

3. Satarupa nymphalis (Speyer, 1879).

TYPE LOCALITY: the Amur.

RANGE: South Primorye, North-East and Central China, Korea.

HABITAT: meadow patches, open tree-stands and river valleys in broad- leafed and mixed forests. These skippers have a very swift flight, they often rest on flowers of Apiaceae, Sorbaria sorbifolia, or Cirsium maackii.

FLIGHT PERIOD: July/August.

PREIMAGINAL PHASES: studied in S Primorye (M.M. and M.A. Omel'ko, 1981). Foodplant: Phellodendron amurensis (Rutaceae). In the first half of July females are observed which swiftly fly around the Phellodendron crown and for a short time sit down on leaf edges at the height about 2 m and higher, with the wings widely spread, to lay eggs. They make up to 2-3 ovipositions on a tree. The eggs are laid as a chain or two adjacent chains containing from 1-3 to 6-11 eggs. Eggs: relatively large, chestnut-coloured, hemispheric with distinct ribs. The larvae hatch on twelfth day, usually in the morning, they make a large round hole on the egg top. They are about 3 mm long, yellowish-green, naked, with black head. The young larva constructs a peculiar shelter by cutting a small triangular plate off a leaf edge and bending it to contact with the leaf surface. The larva hides, with its back down, in this shelter. The shelters of the larvae of the same group are placed at the lateral rib of the same leaf. The larva feeds, usually in the morning, on the edges of the neighbouring leaves, making a silken path there. The first molt happen on 7th day, the second one on 15th day. The larvae overwinter in small groups in a special nest: they spin the upper surface of the leaflets and the main petioles of a leaf to make the leaflets roll to form a winter shelter. (If there were only 1-3 larvae in an oviposition, they migrate to a smaller leaf for hibernation). In late September the larvae span the shelter so as only a small hole is left for the excrement to drop off, in early October they close this hole also. In the late May the larvae abandon the winter shelter and each constructs a new shelter by fastening two young leaves one above another. In this shelter the larva spends the daytime but leaves it for feeding in twilight. The third molt take place in early June, the fourth one 11 days after. A mature larva constructs another shelter from several leaves and spin it inside with the silk. In this shelter it also pupates. Pupa: 28-29 mm long, its stage lasts for 21-22 days. Soon after forming the pupa acquires a waxy bloom.

PECULIAR TRAITS OF IMAGO: F.w.l.: 17-20 mm (the largest of our skippers). The white band on the hind wing is wide and contiguous, on the fore wing it is split into separate spots.

GENUS SPIALIA Swinchoe in Moore, 1912.

Type species: Hesperia galba Fabricius, 1793.

The genus includes 30 species ranging in the Old World.

14. Spialia orbifer (Hübner, 1823). (= sertorius auct. non Hoffmansegg, 1804).

TYPE LOCALITY: Hungary (de Jong, 1974).

RANGE: The non-tropical Eurasia northwards to the southern taiga belt. A local species known from the Asian Russia by scarce findings.

HABITAT: meadow patches in open woodland, birch groves, pine woods, river valleys and mountain slopes. The imagines were observed to feed on flowers of Trifolium, often seen on wet ground.

FLIGHT PERIOD: June, in the mountains up to the first half of July, mostly in a single brood in the territory considered.

PREIMAGINAL PHASES: Foodplants: Sanguisorba minor (Higgins, Riley, 1980).

PECULIAR TRAITS OF IMAGO: F.w.l.: 11-14 mm. The wing upperside is dark- brown or almost black with small white markings; the hind wing underside is dark with three large round white spots forming almost a regular triangle.

SYSTEMATIC NOTE: This species sometimes has been mentioned under the names Hesperia sao Hb. or H. sao Brgstr. (which are invalid as homonyms), or as a subspecies of Spialia sertorius Hoffmansegg, 1804 (this species is distributed in Europe and the part of North Africa adjacent to Spain).

GEOGRAPHICAL VARIATION: The subspecies lugens (Staudinger, 1886), described from Ferghana (Uzbekistan) has been reported for the territory considered: R. De Jong (1974, p.55) has mentioned Onguday (Altai) and Tetyukhe (Primorye). However, the taxon lugens seems to be an independent species not entering N Asia. The butterflies from S Ural and Siberia, and also from the mountains of Kazakhstan, are closer to the nominotypical subspecies (V. and A. Lukhtanov, 1994). They differ from lugens from the Pamiro-Alai Mts. by a dark upperside ground colour, small white spots, an even ground colour of the hind wing underside (without light-brown spots) , and also by the structure of male genitalia. From subspecies orbifer they differ by more elongated wings and a muddy-greenish-brown hind wing underside ground colour (usually brown in orbifer). These butterflies are described as ssp. pseudolugens P. Gorbunov, 1995

Spialia orbifer pseudolugens P. Gorbunov, 1995

Original description:

"...For Siberia and Primorye the taxon lugens Staudinger, 1886, stated from the region of the Ferghana town, was reported (de Jong, 1978). It seems, however, to be an independent species of no relation to the fauna of North Asia. Butterflies from S Ural, S. Siberia, and the mountains of E Kazakhstan are close to the nominotypical subspecies (V. and A. Lukhtanov, 1994). From a typical lugens from the Pamiro-Alai Mts. they differ by a dark ground colour of the wing upperside, small size of white marks, an even colouration of the hind wing underside (without pale-brown spots), and also the male genitalia structure. From the subspecies orbifer they differ by more elongate wings and muddy- greenish-brown ground colour of the wing underside (which is usually brown in the subspecies orbifer). By these characters a subspecies Spialia orbifer pseudolugens P. Gorbunov, sbsp. n. is being stated. F.w.l. in the type series is 11.2-13.2 mm in males and 13.1-13.8 in females. The hind wing underside ground colour in females is brown- ochre, much lighter than in males.

MATERIALS: The holotype: a male - 10.06.1994, W Altai, the station Turgusun environs, the Osinovka River valley (P.Yu. Gorbunov).

40. Ochlodes faunus (Turati, 1905) (= venata auct.; = sylvanus Esper, 1779).

TYPE LOCALITY: Italy

RANGE: Europe, the temperate Asia, in Siberia north to the southern limit of the middle taiga zone, the Sakhalin, the southern Kurile Isles, Japan.

HABITAT: Meadows of various types, forest edges, wasting lands. The imagines visit the flowers of Trifolium, Veronica, Geranium, Dracocephalum, Polygonum, other plants, often rest on the leaves of large herbs (Korshunov, 1969).

FLIGHT PERIOD: June and the first half of July. In South Ural and Zabaikalye [Transbaikalia] the second brood was recorded in August, those butterflies are a bit larger and lighter. In Primorye this species starts flying about a month earlier than O. venata, in late June, and penetrates in more humid habitats.

PREIMAGINAL PHASES: studied in Europe (Eckstein, 1913, Forster, Wohlfahrt, 1955, etc.), the Ural (Chislov, 1977), in Siberia (original data), and, for ssp. herculea Butler, 1881, in Japan (Fukuda et al., 1982). The European data are as follows: Foodplants: Poaceae: Poa, Agropyron, Elytrigia, Triticum, Avena, Brachipodium, Calamagrostis, Festuca, Dactylis, Sasa and others, and also Carex. Eggs: hemispheric, with fine cell sculpture, yellowish-white, later become pale orange. Larva: green with two dark-green dorsal lines, a yellowish (above) and a blueish (beneath) lengthwise lateral stripes, and numerous black dots; the head is brownish. It lives in rolled leaves, hibernates and pupates in spring after further feeding in a cylindrical tuft of silk-spun leaves. Pupa is slender, greenish or greyish, with darker wing cases; its stage lasts for about three weeks. In the Middle Ural a green larva with light lengthwise stripes and relatively large spherical head was found in late June on Chamaecystis ruthenicus (Fabaceae), after 5 days it pupated on a foodplant branch in a frail net-like cocoon. The pupa was green with a long and protruding proboscis case. The imago hatched after 13 days. Japanese data are as follows: Foodplants: Calamagrostis, Sasa, and other Poaceae, and also Carex desicaria. The eggs are hemispheric, white, laid singly on the foodplant leaves. The larva is relatively thick, green; the head is ochre-coloured with a brown streak. It lives in a tuft of silk-spun leaf or 2-3 leaves; pupates in this tuft. The pupa is light-green, with a waxy bloom.

PECULIAR TRAITS OF IMAGO: F.w.l.: 15-18 mm. In male the wing underside is ochre-fulvous with an intensive wide darkening at the outer edge, as different from the similar species O. venatus; the hind wing underside in both sexes is greenish- ochre, usually with distinct yellowish spots which are larger and more diffuse than in H. florinda.

GEOGRAPHICAL VARIATION: While the subspecies faunus Turati, 1905 ranges in West and Central Europe, Ural and the most part of Siberia is inhabited by the subspecies esperi Verity, 1934 described from "Rossia boreali" and differing by a more developed dark pattern on the wing upperside and yellowish-green hind wing underside ground colour, with more distinct yellow spots. The subspecies parvus Kurenzov, 1970, described from Zabaikalye, is close to it. The southern [Russian] Far East is inhabited by ssp. amurensis Mabille, 1909, being easily distinguished by a very distinct dark-brown pattern of the wing upperside and an ochre-brown ground colour of the hind wing underside with contrasted yellowish spots. The subspecies herculea Butler, 1981 inhabits the Sakhalin and the Kuriles, which is described from Japan and approaches esperi by general colouration.

The butterflies from the Sakhalin were designated as sachalinensis Matsumura, 1933. Here we are describing three new subspecies from Siberia. They differ from the nominotypical one by the ground colour, the spots, the presence of their dark rims; in the male genitalia there are differences in the shape of teeth on the valva. In the lateral view the apical process of the valva bears small teeth in ssp. sushkini and is lower than the basal spine, in ssp. planula the process lacks teeth and is on the same level as the basal spine, in ssp. lena the process is lower than the spine and is covered with uneven knobs.
