Afrostylopyga gen. nov.

TYPE SPECIES: Afrostylopyga angolensis sp. nov., designated here .

ETYMOLOGY: The name means “Stylopyga from Africa”.

DIFFERENTIAL DIAGNOSIS: The new genus belongs to the functionally wingless blattids, i.e. cockroaches with tegmina and wings absent or reduced to lateral lobes. This group includes the genera Apterisca Princis, 1963, Brinckella Princis, 1963, Macrostylopyga Anisyutkin, Anichkin & Nguyen, 2013, Maoriblatta Princis, 1966, Miostylopyga Princis, 1966 and Neostylopyga Shelford, 1911. The genera Macrostylopyga , Maoriblatta and Neostylopyga can be readily differentiated from the new genus by the structure of their male genitalia (e.g. shape of sclerites L4C, R1H and R2, see Anisyutkin, 2010; Anisyutkin et al., 2013 and Figs 71-74 of this paper). From the monotypic genus Miostylopyga, described from Java ( Princis, 1966), the new genus differs in larger size, presence of tegmina reduced to lateral lobes (Fig. 3), euplantulae on hind metatarsi and arolia on hind metatarsi.

Afrostylopyga gen. nov. is probably related to the African genera Apterisca and Brinckella, but differs from these genera in the presence of tegmina (Fig. 3), an unmodified abdominal tergite VI and a clearly diminished abdominal tergite VII (Fig. 9) (in Apterisca and Brinckella these tergites are: “Tergite 6-7 eingesenkt und lateral aufwärts gebogen...” Princis, 1963: 90-91). Additionally, the new genus differs from Brinckella in the presence of an arolium on the pretarsi of all legs (Fig. 8).
