Afrotropical parasitoids of the family Braconidae have been extensively studied by numerous hymenopterists [Yu et al., 2012]. However, the species diversity of the parasitoid taxa in the African region is far from being completely known.
The aim of this paper is to document the presence of the doryctine genera Caenophanes Foerster, 1862 and Neurocrassus Šnoflak, 1945 for the Afrotropical Region, and describe two new species of these genera from Democratic Republic of Congo and Republic of Côte d’Ivoire.
The studied material was selected from the collection of the Musee Royal de l’Afrique Centrale (Tervuren, Belgium; MRAC). Specimens were examined using a MC-2 stereomicroscope. The images were taken with a Leica IC 3D digital camera mounted on a Leica® MZ16 microscope and using the Leica Application Suite® imaging system (Museum and Institute of Zoology, Warsaw, Poland). The
terminology employed in this work for the morphological features and measurements follows Belokobylskij and Maetô [2009]. The wing venation nomenclature follows Belokobylskij and Maetô [2009] and Sharkey and Wharton [1997] in parentheses. The holotypes of both new species are deposited in the collection of Musee Royal de l’Afrique Centrale (Tervuren, Belgium), one paratype in the collection of Zoological Institute of the Russian Academy of Sciences (St. Petersburg, Russia; ZISP).
Type species Bracon incompletus Ratzeburg, 1844.
The genus Caenophanes Foerster, 1862 is a small taxon with about 20 described species from the Palaearctic [Belokobylskij, Maetô, 2006, 2009; Belokobylskij et
al., 2011], Oriental [Belokobylskij, 1993], Australasian [Belokobylskij et al., 2004; Belokobylskij, 2010], Nearctic [Haimowitz et al., 2014] and Neotropical [Marsh, 2014] regions. This genus was also recorded from the Afrotropical Region [Zaldívar-Riverón et al., 2008], but without species determination.
Caenophanes is divided into two subgenera [Belokobylskij, 2010]. The nominative subgenus Caenophanes s. str. (with type species Bracon incompletus Ratzeburg, 1844) has an almost worldwide distribution and includes most of the described species. The second subgenus, Pacificophanes Belokobylskij, 2010 (with type species Caenophanes baloghi Belokobylskij, 2010), is known exclusively from New Caledonia.
Some species of Caenophanes have been reared from xylophagous and bark-borer beetle larvae belonging to species of the coleopteran families Cerambycidae, Curculionidae (including Scolytinae) and Buprestidae [Belokobylskij et al., 2011].

Two new species of the genera Caenophanes Foerster, 1862 and Neurocrassus Šnoflak, 1945 171
Type species Neurocrassus tesari Šnoflak, 1945. Genus Neurocrassus Šnoflak, 1945 contains
16 described species occurring in the Palaearctic and Oriental zoogeographical regions [Belokobylskij, Maetô, 2009; Yu et al., 2012]. An undescribed species of this genus has been recorded in North America [Whitfield, 1988]. Described from tropical Africa (Equatorial Guinea), Neodoryctes transversalis Szépligeti [Szépligeti, 1914] (lectotype from Museum für Naturkunde an der Humboldt-Universität (Berlin, Germany) was studied: female, “Sp. G., Makomo, Alcu, Benitogbt, 1-15 X [19]06,
G. Tessmann S. G.”, “463”, “Neodoryct. transversalis Sz.” (handwriting by Szépligeti)) actually belongs to Neurocrassus (Neurocrassus transversalis comb. n.) on the basis of the presence of upper tentorial pits, structure of the second metasomal tergite, and pattern of the head colour. Some species of Neurocrassus have been reared from xylophagous beetle larvae of the families Cerambycidae and Curculionidae [Belokobylskij, Maetô, 2009].
Described below a new Afrotropical species of Neurocrassus belongs to the morphological group characterised by the presence of smooth and more or less distinctly delineated basomedian area on the second tergite (Color plate 16: 23), very small upper tentorial pits (Color plate 16: 14) and the absence of a sclerotised area on the fore wing of male (unknown for this species).
