AFROTROPICAL BUTTERFLIES. MARK C. WILLIAMS. http://www.lepsocafrica.org/?p=publications&s=atb Updated 15 August 2021 Genus Mylothris Hübner, [1819] Dotted Borders In: Hübner, [1816-[1826]. Verzeichniss bekannter Schmettlinge 90 (432 + 72 pp.). Augsburg. Type-species: Papilio poppea Cramer, by subsequent designation (Butler, 1870. Cistula Entomologica 1: 42 (33-58).). = Pseudomylothris Neustetter, 1929. Internationale Entomologische Zeitschrift 23: 191 (191-192). Type-species: Mylothris leonora Krüger, by monotypy. Treated as a junior synonym of Mylothris Huebner, 1819 by Vane-Wright & Liseki, 2011: 86. The genus Mylothris belongs to the Family Pieridae Swainson, 1820; Subfamily Pierinae Swainson, 1820; Tribe Pierini Swainson, 1820; Subtribe Aporiina Chapman, 1895. The other genera in the Subtribe Aporiina in the Afrotropical Region are Belenois and Dixeia. Mylothris (Dotted Borders) is an Afrotropical genus of 106 species, one of which extends extralimitally. First revised by Talbot (1944). A recent phylogenetic analysis of a section of the Pieridae, based on the nuclear gene EF-1α, has shown that the nearest relatives of Mylothris are 13 extralimital genera belonging to the Aporia Hübner, Delias and Catasticta group of genera, all provisionally assigned to the subtribe Aporiina (Braby et al., 2007). The genus was thoroughly revised by Warren-Gash in 2020. Relevant literature: Warren-Gash, 2020 [Revision of genus]. Warren-Gash et al., 2020 [Phylogeny and systematics].

Type locality: [Kenya]: “Kavirondo”. Types in the NHM, London. Warren-Gash (2020:26) designated a lectotype (male), which has the label data “Kavirondo, x.1889, F.J. Jackson”. Diagnosis: Differs from M. sagala in the following respects: smaller; forewing upperside black border extending all the way around, and apex more acute and distal margin less rounded (Kielland, 1990d). Distribution: Democratic Republic of Congo, Uganda, Rwanda, Burundi, Kenya, Ethiopia, Tanzania. Habitat: Submontane forest, apparently at slightly lower altitudes than the closely related M. sagala (Larsen, 1991c). Habits: The flight is weak and several metres above the ground. Males remain on the wing for long periods, coursing along the edges of submontane forest. Females spend most of their time in the canopy, searching for plants on which to oviposit (Larsen, 2005a). Both sexes are occasionally seen at flowers in large numbers (Larsen, 2005a). Early stages: Congdon et al., 2017 [final instar larva]. Larval food: Englerina woodfordioides (Schweinf.) Balle (Loranthaceae) [Warren-Gash, 2020:29; for ssp. clio; as Engleriana]. Erianthemum sp. (Loranthaceae) [Congdon et al., 2017]. “Loranthus” (Santalales) [Kielland, 1990d (Tanzania); Larsen, 1991c: 149 (Kenya)]. Phragmanthera sp. (Loranthaceae) [Warren-Gash, 2020:29; for ssp. clio]. Note: Specimens from Pungo Andongo in Angola probably represent an undescribed subspecies of either M. jacksoni or, more likely, M. albissima (Warren-Gash, 2020: 29).

Images M.C.Williams ex J. Greyling Collection. Type locality: [Kenya]: “Kavirondo”. Types in the NHM, London. Warren-Gash (2020:26) designated a lectotype (male), which has the label data “Kavirondo, x.1889, F.J. Jackson”. Diagnosis: Both sexes of the nominate subspecies are characterized by the forewing upperside being mostly white (Kielland, 1990d). Distribution: Democratic Republic of Congo (east – Ituri, Kivu), Uganda, Rwanda, Burundi, Kenya 5 (west of the Rift Valley), Ethiopia (south and west). Recorded (in error?) from Loliondo in northern Tanzania by Kielland (1990d). Specific localities: Democratic Republic of Congo –Semuliki
