Anacteana gen. n. Figs 89-96

Type species.

- Acteana neavei I. Bolívar, 1912: 79, here designated (NHMUK).

Description.

-Similar to Acteana in size and general appearance, but more robust. Integument as in Acteana . Antennae shorter than the combined length of head and pronotum. Pronotum straight, or weakly convex in profile; medial carina low, lateral carinae weak; hind margin broadly rounded with a small medial indentation. Mesosternal lobes as in Acteana , with broadly rounded angles, quadrate, or transverse in female. Metasternal interspace in both sexes narrow or closed. Tegmina lateral, scale-like, as in Acteana , but much broader, up to half the total length. Genital structures characteristic of Ocnocerus genus group: epiphallus with well developed ancorae (Figs 90, 91, 96).

Discussion.

-On the basis of its genital structures the new genus Anacteana clearly belongs to the Ocnocerus genus group, while Acteana , despite its superficial resemblance, must be regarded as a member of the Parga genus group. The two genera may be differentiated as follows:

A. neavei I. Bolívar, 1912, formerly attributed to Acteana , is now removed to the new genus Anacteana , erected here to accommodate the typical neavei recorded from its type locality in the Katanga province of D.R. Congo, to the Ufipa-Rukwa area of Tanzania and the adjacent Lungu area of Zambia, together with A. neavei burtti (subsp. n.) and A. hollisi (sp. n.) described here. A. neavei burtti occurs in a broad belt across central Tanzania from around Kilosa to Tabora and Kahama, whilst A. hollisi is recorded from the Gabela area of western Angola.

While in their size, rugosity, robust build and micropterism, the two species are superficially alike, they differ markedly in a number of structural features, as given in the keys and the diagnoses.
