Diagnosis
Male easily separated from males of other species of the group by the short and stout, slightly curved aedeagus and the vesica with a tuft of needle-shaped, horizontally oriented cornutus (Fig. 2I); female easily separated from females of other species of the group by the small sclerotized area of the ductus bursae on ostial side, half the length of the ductus bursae, and with the ventral plate of the ostium bursae sclerotized, slightly bilobate and invaginated on the back side (Fig. 3A).
Material examined
Holotype
NIGERIA: ♂, Niger Province, Minna, 9 Oct. 1910, coll. Scott Macfe, 1911-269 (BMNH, Agrotidae genitalia slide 2276).
Other material
NIGERIA: 1 ♂, same locality as holotype; ♀, holotype of Busseola rufdorsata, Niger Province, Minna, 30 Sep. 1910, coll. Scott Macfe, 1911-269 (BMHN, Agrotidae genitalia slide 2273).
Description
The descriptions of the external features of the male holotype and of the female holotype of B. rufdorsata, by Hampson (1910) were accurate. The male looks very similar to the female; however, the general shape of the female’s fore wing is more elongated at the apex (Figs 1A–B, E–F). Descriptions of the genitalia of both sexes were not provided by Hampson (1910).
WINGSPAN. 20 mm (2 ♂♂); 30 mm (1 ♀).
MALE GENITALIA (Fig. 2A, I). Uncus long, widening in distal third, truncated at apex, tufted with long hairs on upper side. Tegumen with medium-sized rounded penniculi, vinculum pointed, with mediumsized triangular saccus, valves short and broad, cucullus rounded and tufted, with medium-sized hairs, coastal margin slightly broadened on inner side and produced into a strong, tooth-shaped spine, roundly pointed and slightly curved inwardly; juxta large, plate-like, widening to the top without sclerotisation. Aedeagus short, stout, slightly curved, with two lateral areas adorned with short setae; hand-shaped vesica with a tuft of needle-shaped, horizontally oriented cornutus.
FEMALE GENITALIA (Fig. 3A). Corpus bursae short and globular, without signum; ductus bursae short, one third as long as corpus bursae, with a small sclerotized area on ostial side, half length of ductus bursae; ductus seminalis from basal part of bursa; ventral plate of ostial bursae sclerotized, slightly bilobate and invaginated on back side, dorsal plate large, broad and weakly sclerotized. Ovipositor lobes relatively short and wide (twice as long as wide), with bluntly pointed apex, dorsal surface bearing numerous short and stout setae.
Bionomics
Biology unknown.
Distribution
Nigeria. Only known from the type locality. The record is from lowland rain forest and secondary grassland (Mosaic #11) (White 1983) (Fig. 4), belonging to the Sudanian bioregion (Linder et al. 2012) (Fig. 5).
