A review of the subfamily Acaenitinae Förster, 1869 (Hymenoptera, Ichneumonidae) from Ukrainian Carpathians.

Ichneumonid wasps of the subfamily Acaenitinae Förster, 1869 are reviewed for the first time from the Ukrainian Carpathians. Two species, Coleocentrusexareolatus Kriechbaumer, 1894 and Coleocentrusheteropus Thomson, 1894 are new records for Ukraine. Arotesannulicornis Kriechbaumer, 1894 is considered to be a junior synonym of Arotesalbicinctus Gravenhorst, 1829 (syn. nov.). A key to species of Coleocentrus of the Carpathians is provided.

Introduction

The subfamily Förster, 1869 worldwide includes about 344 species placed in 27 genera, 8 genera and 42 species of which are found in the Western Palaearctic (Yu et al. 2012).

Rather little is known of the biology of acaenitines. Some Acaenitini are koinobiont endoparasitoids (Shaw and Wahl 1989, Zwakhals 1989). These authors observed that (Panzer, 1800) develops as a koinobiont endoparasitoid of an endophytic curculionid. The female wasp oviposits into first and second instar host larvae and parasitization appeared to retard host development. Three ichneumonid larval instars were discerned and the final instar apparently killed its host about the time unparasitized weevil larvae were pupating. The acaenitine larva then spun a tough parchment-like cylindrical cocon within the host’s pupation chamber (Shaw and Wahl 1989).

The Ukrainian Carpathians are part of the Eastern Carpathians mountain chain and rise in the west of Ukraine within the Lviv, Ivano-Frankivsk, Transcarpathian and Chernivtsi regions. The Carpathians of Ukraine extend from north-west to south-east as a stripe 270 km in length and 100-110 km in width. The Ukrainian Carpathians have an average height of 1000 m and the highest point is 2061 m a.s.l., with relatively soft rocks. Such high-altitude zones as foothill oak forest zone (300–400 m a.s.l.), beech forest zone (400–1300 m a.s.l.), coniferous boreal forest zone (900–1600 m a.s.l.), subalpine and alpine zone (1400–2061 m a.s.l.) can be recognised.

The fauna of Ukraine is poorly studied. Up to now, there are only 10 recorded species (Besser 1835, Meyer 1934, Kasparyan 1981), but there are no data about distribution of the acaenitins in the Ukrainian Carpathians, while the Romanian fauna is more species-rich and comprises 22 species (Constantineanu and Pisica 1977), some of which can possibly also be distributed in the Ukrainian part of the Carpathians.

Materials and methods

This study is mainly based on specimens collected by standard sweep netting in various locations in the Ukrainian Carpathians in 2009-2013. The material deposited in the collection of the Vasyl Stefanyk Precarpathian National University in Ivano-Frankivsk was also studied. The ovipositor‑hind tibia index (in text OTI), which is the length of the ovipositor projecting beyond the apex of the metasoma divided by the length of the hind tibia, is used. Terminology was Townes (1969) followed. Some specimens of European species of acaenitines were examined from the following collections:

HNHM: Hungarian Natural History Museum, Hungary;

ZMLU: Lunds Universitet, Zoologiska Institutionen, Sweden;

ZIN: Zoological Institute, Russian Academy of Sciences, Russia.

Notes

The another European species, Kriechbaumer, 1894, differs from Gravenhorst, 1829 in coloration of legs (which are red except coxae) and in the possession of a fuscous spot on the apex of the fore wing.

Taxon discussion

The main distinguishing characters, between Gravenhorst, 1829 and Kriechbaumer, 1894, given by various authors are the coloration of the first and second tergites of metasoma, which are entirely black in Kriechbaumer, 1894 and light-coloured posteriorly in Gravenhorst, 1829, and pterostigma, which is reddish centrally in Kriechbaumer, 1894 and entirely fuscous in Gravenhorst, 1829. Kolarov (1997) and Constantineanu and Pisica (1977) gave another character, the length of ovipositor sheaths, which are slightly shorter than body in Kriechbaumer, 1894 and as long as the body in Gravenhorst, 1829.

My examination of the holotype of Kriechbaumer, 1894, which is deposited at HNHM, demonstrated that the first and the second tergites have light-coloured (though very weak) posterior margins. The three of metioned above females (collected in the same locality) have first and second tergites varies from entirely black to white-striped. The coloration of the pterostigma is also varies in the studied specimens: from yellowish-brown centrally with fuscous margins to entirely fuscous. The ovipositorial sheaths are as long as the body in the specimens with black tergites, so no evident differences between the two species, Kriechbaumer, 1894 and Gravenhorst, 1829, may be found. Kriechbaumer, 1894 is therefore a junior synonym (syn. nov.).

Gravenhorst, 1829

This genus is characterized by the combination of the following characters: clypeus transverse and basally flat, apex with median tubercle, supra-antennal area without crest between antennal sockets, epicnemial carina absent, propodeum with carinae varying from complete to absent (usually only dorsal longitudinal carinae), claws of fore and mid tarsi simple, fore wing with areolet present (petiolate triangular) or absent; if absent ( Kriechbaumer, 1894), then intercubitus basal to vein 2m-cu, tergites 2–3 of metasoma with basolateral grooves, male parameres with ventral emargination.

Constantineanu and Pisica (1977) recorded Constantineanu, 1929 from Romania, wich is very similar to the female of (Gravenhorst, 1829), but has a fuscous pterostigma (except base), entirely black trochanters, black clypeus and red lateral parts of apical margins of tergites 3-6.

Förster, 1869

This genus is characterized by the combination of the following characters: clypeus transverse and basally flat, apex with median tubercle, supra-antennal area with crest between antennal sockets, notauli strong, hing femora very thick claws of fore and mid tarsi with appressed acute tooth near apex, fore wing with areolet absent, intercubitus basal to vein 2m-cu.

There are another three species of this genus recorded so far from Ukraine, including (Scopoli, 1763) with black metasoma and red hind femora, (Gravenhorst, 1829) with only tergites 2-4 partly red, (Gravenhorst, 1829) which has prepectal carina long, almost reaching subtegular ridge. Constantineanu and Pisica (1977) additionally recorded another 3 new species, described from Romania, (Constantineanu & Constantineanu, 1968) having the entirely black flagellum and ovipositor longer than hind tibia, (Constantineanu and Pisica, 1977), having the black metasoma and (Constantineanu & Constantineanu, 1968) having only tergites 2-4 partly red. But the last two species have also the second metasomal tergite with 2 oblique grooves on each side and that scaracter distinguishes these species from similar (Scopoli, 1763) and (Gravenhorst, 1829) with the same coloration of metasoma respectively (Kolarov and Gürbüz 2010).
