Remark. The taxonomy of M. endoscota (Hampson, 1914) has not been satisfactorily clarified by Hacker et al. (2012), having failed to illustrate the copulatory organ of the female holotype and figuring instead, an externally similar female specimen from Ivory Coast. Despite not examining the genital morphology of the primary type of the species, Hacker described a new subspecies of M. endoscota from Kivu Province, D.R. Congo (M. endoscota undosaria Hacker, 2012). The author of this present paper had the opportunity to dissect the female holotype of M. endoscota housed in the NHMUK, the genitalia of which is illustrated here for the first time (Fig. 89). As there are no considerable differences in the external habitus or the female genitalia of the two subspecies, M. endoscota undosaria is considered here as a mere synonym of M. endoscota. In the same work, Hacker described three new species based exclusively on male specimens (M. peksi, M. simplicifacta and M. mabiriaria Hacker, 2012) despite their undoubted similarities with M. endoscota, namely their markedly short, brownish grey forewings with the conspicuously dark brown median area and the oblique, slightly dentate postmedial line. A fourth species, M. kaduna Hacker, 2012 also reminiscent of M. endoscota, shares the same, rather characteristic male genital morphology with the above-mentioned three taxa. A female paratype of M. kaduna illustrated by Hacker et al. (2012: 290) has proved to be a misidentification of Meganola cirrhographa Hacker & Hoppe, 2012 (cf. p. 288 in Hacker et al. (2012)). Subsequently, Hacker (2014: 143) figured a male specimen identified as M. endoscota undosaria from Nyungwe Forest (Rwanda), without illustrating its genitalia, unfortunately rendering this identification doubtful. Hacker (2014) himself synonymised his M. peksi with M. kaduna, admitting the lack of distinctive features to separate the two species. A series of male specimens in the ANHRT collection reminiscent of M. endoscota recently collected in Cameroon, Guinea and Liberia display identical male genitalia characters (fig. 58) to Hacker’s taxa discussed above (cf. Hacker et al. 2012: 290, 291, 294, 295), namely the conspicuously narrow, medially constricted valva, the long and robust, curved harpe and the short but conspicuous, heavily sclerotized crest-like ventral carinal process of the aedeagus. From the comparative study of genital morphology based on a dozen specimens from various West African localities, it has been possible to conclude that M. kaduna, M. mabiriaria, M. peksi and M. simplicifacta are conspecific and represent the hitherto unknown male of M. endoscota; the four former species are here synonymised with the latter. It is also worth noting that this species has a much wider distribution than had been proposed earlier (Hacker et al. 2012; Hacker 2014).
Distribution. Ghana, Ivory Coast, D.R. Congo, Uganda (Hacker et al. 2012) and Rwanda (Hacker 2014). The specimens from Cameroon, Guinea and Liberia represent new country records.
