INTRODUCTION

The subfamily Alysiinae is one of the most peculiar and diversified sub- families of the endoparasitoids of the family Braconidae. The species of this subfamily parasitize the larvae of several families of Diptera (more common Agromyzidae, Phoridae, Ephydridae, Chloropidae, Calliphoridae, Anthomyiidae etc.) and finish their development in the puparium of flies. More than 80 genera have been described and most of these are restricted to temperate areas of the Holarctic Region (FISCHER 1971; SHENEFELT 1974; WHARTON 1980; BELOKOBYLSKIJ 1998; TOBIAS 1998). About 65 genera were recorded in the Palaearctic fauna including 55 genera of the fauna of Europe. Genera and species which were recorded from Poland (34 genera and 228 species) are from the both known alysiine tribes (HUFLEJT 1997; BELOKOBYLSKIJ 2004), but this number does not show the true diversity of the Polish alysiine fauna. Three genera from tribes Alysiini (Asyntactus MARSHALL, 1892 and 432 SERGEY A. BELOKOBYLSKIJ

Carinthilota FISCHER, 1975) and Dacnusini (Epimicta FOERSTER, 1862) are recorded in this paper as new for the fauna of Poland. The redescriptions of these genera and three species with discussion about distribution and contents of these groups are presented below. The terminology for wing venation follows that of BELOKOBYLSKIJ & TOBIAS (1998).

SYSTEMATICS PART

Asyntactus MARSHALL, 1898

Type species – Asyntactus rhogaleus MARSHALL, 1898.

The presence of different types of sculptures on metasomal tergites behind the first one is one of the main diagnostic characters for several alysiine genera. This character is known in such Holarctic genera as Apronope ACHTERBERG, Asyntactus MARSHALL, Bobekia NIEZABITOWSKI, Glyphogaster MUESEBECK et WALKLEY, Hylcalosia FISCHER, Oenonogastra ASHMEAD, Phasmalysia TOBIAS, Phasmidiasta WHARTON, Separatatus CHEN et WU, Symphanes FOERSTER, Trachyusa RUTHE (Alysiini), Aristelix NIXON, Coelinius NEES, Eucoelinidea TOBIAS, Epimicta FOERSTER, Laotris NIXON, Orientelix TOBIAS, Parasymphia TOBIAS, Polemochartus SCHULZ, Sarops NIXON, Synelix FOERSTER, and Trachionus HALIDAY (Dacnusini). Asyntactus MARSHALL is one of the most rare alysiine genera which has more than 3 sculptured basal tergites on dorsoventrally depressed metasoma (MARSHALL 1892; FISCHER 1971). Only two West Palaearctic species are described in this genus - A. rhogaleus MARSHALL and A. sigalphoides MARSHALL. The hosts of this genus are yet unknown. Description. Head transverse.

According to FISCHER (1971), differences between A. rhogaleus MARSHALL (female, type species) and A. sigalphoides MARSHALL (male) in the sculpture of the apical segments of metasoma and in its coloration are not distinct and can be explained as sexual 436 SERGEY A. BELOKOBYLSKIJ differences or connected with ecological conditions of the specimens development. At least, the studied male from Poland has smooth tergites behind the fourth one from the one side (character of A. sigalphoides), and reddish brown coloration of the metasoma from third tergites to apex of metasoma from the other side (character of A. rhogaleus). It is necessary to study more material from different places to understand the real size of the morphological variety among these forms.

Carintilhota FISCHER, 1975

Type species – Carinthilota parapsidalis FISCHER 1975.

The genus Carinthilota was described by FISCHER (1975) from Austria. The second European species of this genus, C. vechti ACHTERBERG, with white coloration of the apical segments of antenna was found later in the Netherlands (ACHTERBERG 1988). During revision of the alysiine fauna of the Russian Far East additionally two species (C. lada BELOKOBYLSKIJ and C. mavka BELOKOBYLSKIJ) were discovered in this region (BELOKOBYLSKIJ 1998). Both European species were recorded also in the East Palaearctic: C. parapsidalis FISCHER in China (CHEN & WU 1994) and C. vechti ACHTERBERG in Primorskiy Territory of Russia (BELO- KOBYLSKIJ 1998). In this paper the genus Carinthilota (as well as C. vechti ACHTERBERG) is recorded in the Polish fauna for the first time. It is interesting to underline that one of the main characters of C. vechti is the contrasting yellowish-white coloration of the apical segments of antennae. Such colour pattern (with pale apical or subapical segments of antenna) is not common in the subfamily Alysiinae and is known in the Palaearctic Region for many species of Idiasta FOERSTER, for Phaenocarpa stackelbergi TOBIAS et GURASASHVILI, species of Asobara FOERSTER (A. japonica BELOKOBYLSKIJ) and Alysiasta WHARTON (A. udaegae BELOKOBYLSKIJ). The host of this genus is yet unknown. This genus is a member of the Aspilota- group genera, thus it is possible to suggest that hosts of Carinthilota species are dipterous larvae from the family Phoridae (common hosts for Aspilota FOERSTER and related genera). Description. Head transverse. Ocelli arranged in almost equilateral triangle. Vertex with rather fine narrow median longitudinal furrow; frons without longitudinal furrow. Eyes glabrous. Furrow between antennal socket and eye absent. Clypeus wide. Paraclypeal areas enlarged, but rather far separated from eye. Mandible narrow and rather long, weakly widened apically, with 3 teeth; upper tooth rather long and pointed, median tooth narrow and the longest; lower tooth rather large (almost same length as upper tooth), widely rounded. Antennae thick, filiform, rather long. First flagellar segment distinctly longer than second segment. All flagellar segments longer than wide. Apical segment weakly pointed apically. Mesosoma 1.3 times as long as high. Pronotum without pronope. Mesonotum highly and almost perpendicularly raised above pronotum. Notauli complete, rather deep and crenulate. Median lobe of mesosoma entirely covered with dense SYSTEMATIC AND DISTRIBUTION OF THREE RARE ALYSIINE GENERA 437 long setae, lateral lobes glabrous at most part. Prescutellar depression very long, deep, with distinct median carina. Metanotum without tooth. Sternauli rather narrow, deep, coarsely crenulate.

Pterostigma very narrow and elongate, fused with metacarpus without border. Radial cell of fore wing not shortened. Radial vein arising not far from parastigma. Second radial abscissa distinctly longer than first radiomedial vein. Both radiomedial veins present. Second radiomedial cell narrowed posteriorly. Recur- rent vein distinctly postfurcal. Discoidal cell anteriorly shortly petiolate. Nervulus postfurcal. Parallel vein arising almost from middle of apical side of brachial cell. Brachial cell closed distally. In hind wing, first abscissa of mediocubital vein almost twice as long as second abscissa; submedial cell rather large. Recurrent vein almost absent. Legs. Hind coxa without basoventral tubercle. Hind femur claviform, rather long. Basitarsus of hind tarsus short, 0.6 times as long as second-fifth segments combined. Claw simple and rather small. Metasoma more or less compressed, especially posteriorly; distal segments distinctly protruding behind third tergite. First tergite narrow and long, weakly widened toward apex, with small dorsope, with rather short and weakly convergent posteriorly dorsal carinae. Second suture very shallow, almost indistinct. Only second tergite with fold in basal half between dorsal and lateral surfaces of tergite. Third-sixth tergites with subapical rows of sparse long setae, glabrous for the most part. Second and following tergites smooth. Ovipositor short. Distribution. Palaearctic Region.
