INTRODUCTION

The genus Nokona was described by Matsumura as a subgenus of Paranthrene

Hübner, 1819 [“1816”] with Paranthrene yesonica Matsumura, 1931 [= Sciapteron regale Butler 1878] as the type species (Matsumura, 1931). According to our un-published data the genus, in its modern interpretation, is polyphyletic. It distributes in the eastern part of Palaearctic, Oriental and Australian regions and includes somewhat less than 50 species (Gorbunov & Arita, 1995; 2001; Arita & Gorbunov, 2001; Pühringer & Kallies, 2004; Kallies et al., 2014). By the structure of both male and female genitalia Nokona (sensu lato) can be clearly divided to several groups. The new species described below if a member of the N. regalis species-group.

All labels of the holotype are shown in detail. Each label is separated by quotation marks, and lines in a label separated by a “/”. The holotype of the new species is deposited in the collection of the National Science Museum, Tokyo, Japan (NSMT).

4

slightly shorter than vinculum, somewhat broader and rounded basally; aedeagus (Fig. 6) rather thick, slightly longer than valva, with a small well-sclerotized carina penis; vesica with numerous minute flat cornuti.

FEMALE. Unknown. INDIVIDUAL VARIABILITY. Unknown.

Figs 3–6. Male genitalia of Nokona sulawesiensis sp. n. (genital preparation No OG–017-

2014): 3 – tegumen-uncus complex; 4 – valva; 5 – saccus; 6 – aedeagus. Scale bar: 0.5 mm. DIFFERENTIAL DIAGNOSIS. By the structure of the male genitalia Nokona

sulawesiensis sp. n. seems to belong to N. regalis (Butler, 1878) species-group. Su-perficially this new species somewhat resembles to N. poecilocephala (Diakonoff, 1968 [“1967”]), but can be separated from it by the coloration of the vertex (bright orange mixed with black in the species compared), abdomen (each tergite with a narrow yellow stripe distally in N. poecilocephala), coloration of forewing (dorsally with strong indigo-green sheen in the species compared) and by the conformation of

5

the male genitalia (Figs 3–6 vc fig. 349 in Diakonoff, 1968). From N. acaudata Arita et Gorbunov, 2001, N. sulawesiensis sp. n. differs by the coloration of the tegula (with a large yellow-orange spot at base of forewing in the species compared), abdomen dorsally (tergite 2 with an admixture of orange scales on distal half; tergite 4 with a broad orange stripe distally; tergite 6 with a narrow orange stripe distally in N. acaudata) and by the presence of the external transparent area of the forewing (completely opaque in the species compared) and by the structure of the male genitalia (cp. Figs 3–6 with fig. 55a–d in Arita & Gorbunov, 2001).

BIONOMICS. The host plant and larval bionomics are unknown. The type was collected in the end of February.

HABITAT. Unknown. DISTRIBUTION. Known from the type-locality in South Sulawesi. ETYMOLOGY. This new species is named after the island of Sulawesi, where

it was collected.

INRODUCTION

The genus Chrysotus Meigen, 1824 (Diptera: Dolichopodidae) comprises more than 365

species distributed all over the world, 91 of which occur in the Palearctic Region (unpublished data of authors). The Palaearctic species of Chrysotus were revised by Negrobov and his co-workers in a series of publications (Negrobov 1980; Negrobov & Maslova, 1995; Negrobov et al., 2000, 2003). The last key to males of the Palaearctic species was published fifteen years ago (Negrobov et al., 2000).

Recently three species of the genus Chrysotus were described from Russia, namely Ch. brooksi Negrobov, Selivanova et Maslova, 2013 from Primorskii krai (Negrobov et al., 2013) and Ch. komovi Negrobov, Barkalov et Selivanova, 2014 and Ch. tricaudatus Negrobov, Barkalov et Selivanova, 2014 from Taimyr (Negrobov et al., 2014).

Thirteen Palaearctic species of Chrysotus were described from China (Wang & Yang, 2006, 2008, 2009; Wei & Yang, 2007; Liu et al., 2013, 2015). The key to males of the known Chinese species was published (Yang et al., 2011).

10

Masunaga (2014) recorded from Japan only three species of the genus Chrysotus: Ch.

cilipes Meigen, 1824, Ch. nudisetus Negrobov et Maslova, 1995 and Ch. pulchellus Kowarz, 1874.

In this paper we describe two new species of Chrysotus from Japan and Russia. In addition one species is firstly recorded from Japan below. The specimens examined were collected in Japan (Honshu Island) by Dr V.N. Fursov and in Russia (Sakhalin Island) by Dr V.V. Zlobin.

Holotypes of the new species are deposited in the collection of the Zoological Institute of the Russian Academy of Sciences, St Petersburg, Russia (ZIN). The paratypes are kept in the collections of ZIN, the Schmalhausen Institute of Zoology of National Academy of Sciences Ukraine (IZU), and Voronezh State University, Russia (VSU).

Legs: Fore coxa with white hairs, mid and hind coxae with dark hairs. Femora mostly yellow, mid and hind coxae in major part, apex of hind femora, apex of fore and mid tarsi dark. Apex of hind tibia and hind tarsi in major part yellowish-brown. Fore femur without long hairs. Fore tibia with 1 short anterodorsal and 1 short posterodorsal setae, and with short dorsal hairs. Fore tarsus without long hairs. Ratio of fore tibia and tarsus (from 1st to 5th): 1.8: 0.6: 0.5: 0.3: 0.4. Mid and hind femora with short black preapical hairs setae. Mid tibia with 2 anterodorsal and 2 posterodorsal setae. Ratio of mid tibia and tarsus (from 1st to 5th) 3.1: 1.6: 0.8: 0.5: 0.3: 0.4. Hind tibia with 2 short anterodorsal, 3 posterodorsal setae and short erect exterior hairs. 1st segment of hind tibia with short erect exterior hairs, length of which equal of femur width.

Wings: Hyaline, with dark venae. R4+5 and M1+2 slightly divergent apically. Ratio of

costal section between R2+3 and R4+5 to that between R4+5 and M1+2 1.5:0.6. dm-cu distinctly shorter than apical part of M3+4 (0.4:2.5). Halter and cilia of lower calypter yellow.

Abdomen: Dark-green with metallic shiny, grey dusted on sides, covered with black hairs. Epandrium oval; surstylus curved on apex. Phallus with two lateral processes at apex. Cerci brown, with light hair.

FEMALE unknown. MEASUREMENTS. Body length: 1.2–1.3 mm, wing length: 1.2–1.3 mm. DIAGNOSIS. In the key to Palearctic species of Chrysotus (Negrobov et al., 2000), the

new species runs to Ch. neglectus (Wiedemann, 1817), and can be distinguished from the latter by following characters:

1(2) Hind femora yellow. Postpedicel small, oval. Posterior part of wing with lobe …........…

……………………………..........................… Chrysotus neglectus (Wiedemann, 1817) 2(1) Hind femora with dark spot at apex. Postpedicel large, triangular in lower part. Posterior

part of wing without lobe ..…….. Chrysotus tagoi Negrobov, Maslova et Fursov, sp. n.
