Diagnosis.
Forewing length
21–23 mm
.
Afroracotis smithi
sp. n.
is the only species easily recogniseable from its habitus within the subgenus
Zebracotis
, due to its rather dark grey colouration and the conspicuous off-white quadrangular subterminal patches of the fore- and hindwings. According to the configuration of the vesica, the new species belongs to the
A. chaineyi
lineage including
A. lydiae
and
A. madagascariensis
, from which it is clearly distinguished by the shorter protractile diverticulum, armed with a markedly longer, more robust, apically pointed cornutus and the more numerous and smaller distal cornuti situated at the base of the vesica ejaculatorius. In the female genitalia of the new species, the heavily sclerotised cervix/corpus bursae complex has a substantially shorter narrow-infundibular posterior section and more extensive striate sclerotization than in
A. chaineyi
and
A. lydiae
, whilst that posterior section is somewhat longer than in
A. madagascariensis
. Additionally, the bulged side of the bursa copulatrix is entirely sclerotised up to the membranous, conical posterior projection with weak striation and with a large, smooth-surfaced sclerotised plate, supposedly serving as a receptive surface for the large cornutus during copulation. The bursa copulatrix of
A. lydiae
and
A. madagascariensis
bears a heavily sclerotised disc-like medial plate presumably playing the same role. The membranous anterior part of the bursa copulatrix is produced into a distinctive conical protrusion in the new species, whereas it is evenly rounded in
A. chaineyi
. It is worth noting that the corpus bursae of the West African and Cameroonian specimens are markedly narrower than in the single dissected Zambian female specimen which may refer to a taxonomic division between the eastern and western African populations. As the males do not display any morphological divergences throughout its entire range, and since genetic studies could not be carried out on West African specimens due to the age of the accessed materials,
A. smithi
is considered here to be a consistent, widely distributed species.
Genetic information.
Afroracotis smithi
belongs to the BIN URI: BOLD:AAF9530, BIN—sharing with
A. zebrina
,
A. chaineyi
,
and partly with
A. milesi
and
A. lydiae orientalis
, although forming a separate cluster in the ML as well as in the BI trees. The intraspecific divergence is 0.00–0.34%.
Etymology.
The new species is named in honour of Richard Smith, Chairman of the Board of Trustees, African Natural History Research Trust, acknowledging his unrivalled efforts in forwarding entomological research in Sub-Saharan Africa.
Distribution
(
Map 6
).
Afroracotis smithi
is widely distributed along the Equator with confirmed records from
Cameroon
,
DRC
,
Gabon
,
Ivory Coast
,

and
Zambia
