Abstract

A revision of the small Afrotropical holcobraconine genus Ivondrovia Shenefelt & Marsh, 1976 (Doryctinae) is provided. A new species from Kenya, Ivondrovia grangeri sp. n., is described and illustrated. The illustrated redescriptions of the genus Ivondrovia and its type species Lophogaster seyrigi Granger, 1949 are given. The two known species of this genus are keyed.

Introduction

The doryctine genus Ivondrovia Shenefelt & Marsh, 1976 was originally described from Madagascar by Granger (1949) as Lophogaster Granger, 1949 (a primary homonym for Lophogaster Sars, 1857 of Crustacea) only containing its type species, L. seyrigi Granger, 1949. In the World Catalogue of Braconidae, Shenefelt and Marsh (1976) subsequently changed this preoccupied name to Ivondrovia. This taxon was originally included by Granger (1949) in the subfamily Odontobraconinae which is now regarded as the tribe Holcobraconini within the braconid subfamily Doryctinae (Belokobylskij 1992; Belokobylskij et al. 2004; Zaldívar-Riverón et al. 2008).

For the reclassification of subfamily Doryctinae, Belokobylskij (1992) examined the holotype of Ivondrovia type species, L. seyrigi, and classified Ivondrovia within the monotypic subtribe Ivondroviina belonging to the tribe Holcobraconini. The Ivondroviina was characterized by the following combination of characters: hind coxa simple (without dorsal projections); occipital carina and frons keel absent; propodeum with distinct medio-posterior areola and basal carinae but without total foveolate sculpture; first flagellar segment of antenna not longer than second one; recurrent vein (1m-cu) of fore wing postfurcal in comparison with the first radiomedial vein (2RS); radial vein (RS) of hind wing arising from basal vein (1r-m) and rather far from costal vein (SC+R); second metasomal tergite long medially and laterally and very short sublaterally.

The biology of Ivondrovia is still unknown. However, since the majority of the Doryctinae are known as ectoparasitoids of bark boring and xylophagous beetle larvae, and several holcobraconine species belonging to the genera Zombrus Marshall, 1897 and Odontobracon Cameron, 1887 were reared from large Capricorn beetle larvae, it is likely that species of Ivondrovia also infest larvae of the beetle family Cerambycidae for their development.

During ongoing work on the molecular phylogeny of the tribe Holcobraconini, the authors discovered a second new species of Ivondrovia from Kenya. Here we describe this new species and provide a key for determination of the two known species of Ivondrovia.

Materials and methods

The terminology employed for morphological features and measurements follows Belokobylskij and Maetô (2009). The wing venation nomenclature follows Belokobylskij and Maetô (2009), with Sharkey and Wharton (1993) terminology shown in parentheses. Specimens were examined using a MC–2 stereomicroscope. Photographs were taken with a Leica IC 3D digital camera mounted on a Leica MZ16 microscope and using the Leica Application Suite imaging system at the Museum and Institute of Zoology, Warsaw, Poland. The photograph images were enhanced and plate was composed using Adobe Photoshop.

The specimens examined in this study are deposited in the following collections: Colección Nacional de Insectos, Instituto de Biología, Universidad Nacional Autónoma de México (UNAM), Muséum National d’Histoire Naturelle, Paris, France (MNHN), and Zoological Institute of the Russian Academy of Sciences, St Petersburg, Russia (ZISP).
