Abstract

Six new species of the ichneumonid genus Aneuclis are described from South Africa: A. laminosa sp. n., A. lanternaria sp. n., A. larga sp. n., A. lasciva sp. n., A. lugubris sp. n., and A. vannoorti sp. n. A key to known Afrotropical species of Aneuclis is provided.

INTRODUCTION

This contribution continues the study of Afrotropical tersilochines started in my previous paper (Khalaim 2007), in which a key to genera is provided. This article covers the genus Aneuclis Förster, 1869. Species of Aneuclis have previously been described only from the Palaearctic Region (Yu et al. 2005).

Aneuclis belongs to the “Diaparsis” genus group, which also includes the genera Diaparsis Förster and Sathropterus Förster, and is characterized by the first metasomal segment having isolated glymma (not joined by a furrow to ventral part of postpetiole) or lacking glymma, the fore wing having the second recurrent vein interstitial or postfurcal, and the propodeum almost always having a basal keel. Aneuclis differs from the genus Diaparsis by the brachial cell of fore wing being widely open at apex and the posterior part of the postnervulus being absent (Khalaim 2007, fig. 6), and from the genus Sathropterus by the presence of a second recurrent vein and by the ovipositor being evenly upcurved, not sinuate apically.

Aneuclis is a medium-sized genus with 16 species described from the Palaearctic Region (Khalaim 2004). Townes (1971) also mentioned undescribed species from the Nearctic, Oriental and Afrotropical regions. Six species are described below from South Africa: A. laminosa sp. n., A. lanternaria sp. n., A. larga sp. n., A. lasciva sp. n., A. lugubris sp. n. and A. vannoorti sp. n. An identification key to known Afrotropical species of Aneuclis is provided.

In the Palaearctic Region, species of Aneuclis have been reared from coleopteran hosts of Chrysomelidae, Curculionidae and Nitidulidae on cruciferous plants, and are mainly associated with herbaceous landscapes. No details are known of the host preferences of Afrotropical species.

MATERIAL AND METHODS

Material from the collections of the Iziko South African Museum in Cape Town was studied. Photographs were taken via a Leica MZ16 stereomicroscope with an integrated Leica camera. The images were assembled with Helicon Focus software and edited in Adobe Photoshop CS2. Terminology for morphological structures mainly follows Townes (1969). Types of the new species are deposited in the Iziko South African Museum (SAMC) and the Zoological Institute of the Russian Academy of Sciences, St Petersburg (ZISP).

TAXONOMY

Genus Aneuclis Förster, 1869

  • Type species: Isurgus rufipes Szépligeti, 1899 (Thersilochus maritimus Thomson, 1889).

  • Diagnosis: The genus includes small species with body length about 3.0 mm. Head and mesosoma more or less granulate, sometimes with smooth shining areas, impunctate or finely punctate. Head rather strongly narrowed behind eyes in dorsal view, temple distinctly shorter than eye width. Antenna filiform. Flagellum of Afrotropical species 14- or 15-segmented (13–23-segmented in Palaearctic species). Notaulus absent or weak, sometimes substituted by a short carina. Sternaulus absent or weak, in anterior part of mesopleuron. Propodeum with basal keel (sometimes indistinct) which is shorter than the apical area. Second recurrent vein interstitial or postfurcal. Brachial cell widely open at apex, with posterior part of postnervulus absent. First metasomal segment slender, with petiole more or less round in transverse section, with small isolated glymma (not joined by a furrow to ventral part of postpetiole) or without glymma. Ovipositor evenly upcurved, with shallow dorsal subapical depression, from short to very long.

    All species are rather uniform and very few diagnostic characters are available. Males of Aneuclis are much more difficult to recognize than the females.
