Description Habitus Wingspan: ♀ 39-44 mm . General aspect similar to the male, larger and with a bigger abdomen. Genitalia Seventh segment slightly sclerotized, one and a half times longer than the sixth segment; the sternite with a deep concavity in the middle of its caudal margin to accommodate the sterigma; pleurae with one triangular membranous thickness, cephalad with a shallow pouch consisting of membranous thick tissue. Eighth segment slightly sclerotized, as long as the sixth one; sternite with two membranous lateral shallow concavities and the central portion forming a well sclerotized squarish lamella postvaginalis. Anterior apophyses very short, about one third as long as the eight segment; posterior apophyses two times longer than the anterior ones. Dorsal pheromone glands a little longer than the posterior apophyses. Ostium bursae membranous, no lamella antevaginalis. Ductus bursae almost as long as large broad, internally covered by spiculate thorns; its caudal portion naked, with a small dorsal dome-shaped appendix holding the ductus seminalis. Corpus bursae lenticular, internally covered by spiculate thorns except around the signum. Signum concave, roundish, with small thorns. Distribution Cameroon ( type locality, Birket-Smith 1965 ). Nigeria ( Birket-Smith 1965 ); Gabon (new locality). Remarks This species, hitherto only known from the type locality and Nigeria , is now also reported from Gabon . The female is recorded and hereafter described for the first time (an allotype is designed in the sense of ICZN art. 72.1.3, Recommendation 72A).
