Highly distinctive genus, characterized by sternauli deeply impressed and extending beyond mid–length of mesopleuron. Head polished and smoothly sculptured, dorsally expanded and flattened, somewhat triangular in profile; mandible bidentate, upper tooth 1.5–2.0× longer than lower tooth; subocular groove present; clypeus transverse, its ventral margin regularly convex; flagellum of female regularly enlarged toward apex; occipital and hypostomal carinae joining at mandibular basis; epomia weak; notaulus weakly impressed; postpectal carina complete and strong; propodeum moderately elongate, regularly curved in profile view, propodeal carination well developed to about absent; fore wing with areolet open, hind wing with 1/Cu&cu–a straight and distal abscissa of Cu1 absent; tarsal claws simple; gastrocoelus and thyridium indistinct; ovipositor distinctly extending beyond apex of metasoma.

Because of its strong and long sternaulus, this genus was first placed in the Cryptinae by Seyrig (1952), and subsequently moved to the Ichneumoninae by Townes (1971).

The genus was previously only known from Madagascar, with a single species. Here we report a new species from South Africa.

The two specimens from Kivu (MRAC) differ significantly from the type series: they are about half the size with shorter antennae; the mesopleuron is more smoothly sculptured, transversely strigose; and the OT index is 0.3. The coloration and sculpture are otherwise similar. Whether or not they actually belong to the same species is currently unclear. We refrain from delimiting these specimens as a separate species until further material is at hand to assess the degree of intra–specific variation within this taxon.

Diadromus is a moderately large genus of 31 species, occurs almost worldwide, but has not been reported from South America or tropical Africa. The subgenus Thyraeella is highly unusual among the other species of the genus: it is mainly defined by the peculiar position of the junction between the hypostomal and occipital carinae, the complete postpectal carina and by having the ventral margin of the clypeus less impressed than in Diadromus s. s. The subgenus only includes the species Diadromus collaris.

South Africa, Mexico. Otherwise widespread from Europe and the Middle East to the Indo–Australian region, China and Japan. Introduced into numerous countries in the Indo–Australian and West Indies regions for biocontrol purpose.

Commonly used as a biological control agent of Plutella xylostella (Lepidoptera: Plutellidae) on cultivated cruciferous crops (Brassica spp.). Also reared from Acrolepiopis assectella (Lepidoptera: Plutellidae) (Kalmès and Rojas–Rousse 1980). The geographical origin of this species is not clear, neither is that of its host Plutella xylostella, which was originally considered to be European. Kfir (1998), based on an assessment of the origins of the moth’s host plants and the complex of natural enemies attacking the diamondback moth, suggested that the host species is from southern Africa. Diadromus collaris is very common in South Africa, where it reproduces sexually (Kfir 1997, 1998), and in Europe, where it was reported to be thelytokous with mainly females known. It hence was speculated to be of African origin (Kfir 1998). However, Liu et al. (2001) report that Diadromus collaris is arrhenotokous in Australia, Malaysia, China, Taiwan and France, and suggested that the diamondback moth originates in China. Diadromus collaris is probably present throughout the Afrotropical region; however, it is not present in Reunion, where the diamondback moth is only a minor pest (Rousse pers. obs.).

Mandible bidentate; occipital and hypostomal carinae joining close to or distinctly above mandibular base; area superomedia defined, receiving costula at or beyond middle; gastrocoelus indistinct, thyridium absent; fore wing with areolet closed; hind wing with distal abscissa of Cu1 present, hardly distinct to fully pigmented (Perkins 1959, Selfa and Diller 1994).

The genus is represented by 57 species, with a worldwide distribution with the exception of the Australasian and Antarctic regions. Dicaelotus cariniscutis (Cameron, 1906) was the only Afrotropical species previously known. We describe here three new species from South Africa.

This species and the following one are sympatric and closely related. They share the same microsculpture, particularly the coarsely punctate and strigose mesosoma and the blunt median tubercle on the face. They are, however, distinct, and can be differentiated by the length of antennae, the pigmentation of the distal abscissa of Cu1 on the hind wing and the strikingly distinct coloration pattern.

Named in honour of the Table Mountain National Park, to which the type locality belongs. In 1503, a Portuguese explorer, Antonio de Saldanha, climbed and named the mountain Taboa do Cabo (= Table of the Cape). Subsequently the mountain became known as Tafelberg (= Table Mountain) to the first European Dutch settlers of the Cape who arrived in 1652.

Heterischnus is a very distinct genus of Phaeogenini and can be separated from other genera in the tribe by the combination of the following characters: mandible unidentate and falciform; clypeus separated from face laterally by a deep groove encompassing anterior tentorial pits; basal flagellar segments slender and long; vertex long and slightly convex behind ocelli; hypostomal carina joining occipital carina distinctly at or above mandibular base; epicnemial carina strongly raised ventrally and flexed over the base of the fore coxae; notaulus distinct anteriorly, deep and long; fore wing with areolet closed, hind wing with distal abscissa of Cu1 present and connected to 1/Cu&cu–a; tarsal claws simple; gastrocoelus nearly indistinct to deep, thyridiae wide; ovipositor extending relatively strongly beyond apex of metasoma (Perkins 1959, Selfa and Diller 1994).

The genus is represented by 28 species in the Afrotropical, Nearctic and Palearctic regions, with three described Afrotropical species. We add here one species from Southern Africa and one from Tanzania.

Senegal, Tanzania.

Two males of this species have been collected. Surprisingly, the two collection sites are located at the two lateral extremities of the African continent, both specimens showing only slight differences in the density of punctation and the length of antennae. However, both localities fall within the arid Sahel belt that extends from Senegal in the west to Ethiopia and Somalia in the east, paralleling the southern edge of the Sahara desert. From the horn of Africa this arid habitat extends south down the eastern side of Africa through Kenya to northern Tanzania where Mkomazi Game Reseve is situtated. It must then be presumed that this species is far more widespread than indicated by the known distribution. We predict that the species will likely occur throughout the Sahel zone.

Madagascar (Antananarivo, Antsiranana and Fianarantsoa provinces) (Heinrich 1938).

This species is very closely related to the following one. Heinrich (1938) considered Hoplophaeogenes curticornis to be a distinct species although both species are sympatric and the single known female specimen of Hoplophaeogenes curticornis differs from the two known females of Hoplophaeogenes amoenus only by its shorter antennae and darker face and metasomal apex. These differences being much slighter than the sexual dimorphism within the species. Heinrich could not attribute with certainty the three Hoplophaeogenes males he examined to either of these species. Subsequently, he decided to allocate them arbitrarly to Hoplophaeogenes amoenus but did not include them in the type material. Lacking enough supplementary material, we decide here to follow Heinrich’s choice and allocate the male collected at Fianarantsoa to Hoplophaeogenes amoenus. Compared to the type female of Hoplophaeogenes amoenus, these males differ by the entirely black flagellum, the more extensively black head, and the dark red metasoma. The only male with complete antennae (BMNH) has 26 flagellomeres.

The general habitus of Kibalus gen. n., the hemispherical head with long vertex, the junction of the hypostomal and occipital carinaeat the mandibular base and the complete postpectal carina suggest that it is related to Lusius Tosquinet, 1903, from which it differs mainly by the bidentate mandible, the closed areolet and the absence of elongate male genitalia.

Lusius is also a very distinct genus of Phaeogenini, close to Heterischnus. It can be separated from other genera in the tribe by the combination of the following characters: head hemispherical; mandible unidentate and falcate; basal flagellar segments slender and long; vertex long and slightly convex behind ocelli; occipital and hypostomal carinae joining at mandibular base; notaulus complete, ending posteriorly in a median depression; fore wing with areolet open, hind wing with distal abscissa of Cu1 absent; gastrocoelus long with thyridium faint; ovipositor extending beyond apex of metasoma; male with gonoforceps mesochorine–like, i.e. expanded into elongate process (Tosquinet 1903, Baltazar 1964; Diller 2006).

The genus is represented by seven species in the Afrotropical, Neotropical and Oriental regions, with one Afrotropical species. We describe here a new species from Uganda.

Flummox: “be a mystery or bewildering” in reference to the atypical Ichneumoninae habitus of the genus, which originally flummoxed placement of this new species. Noun in apposition.

Uganda. Nigeria? (cf. comments).

The CNCI specimen, from Nigeria, was not included in the type material. It indeed exhibits surprising differences: flagellum bi–colored, yellow from base to flagellomere 15, then with remaining flagellomeres black; overall coloration yellow without darker dorsal markings; and median carina of frons absent. The clypeus is, however, typical of Lusius flummox. Whether this specimen belongs to Lusius flummox, represents a distinct new species, or is an intermediate linking Lusius flummox and Lusius tenuissimus is currently unclear. We refrain from describing it as a new species until further material is available to enable an informed assessment of this species’ variability.
