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).
