Two new tiger-moth species from Afrotropics with reviews of genera Pericaliella and Monstruncusarctia (Lepidoptera, Noctuoidea: Erebidae, Arctiinae) Author Dubаtolov, Vlаdimir V. text Zootaxa 2017 2017-11-24 4353 3 577 583 journal article 31337 10.11646/zootaxa.4353.3.11 533b6aa5-1906-45e5-b36b-e5f32cf6bbf6 1175-5326 1065722 07F091F4-1C0F-44C0-98BF-F13B511EDAA1 Monstruncusarctia Dubatolov et Haynes, 2008 Dubatolov & Haynes, 2008 : 356–357. Type species: Alpenus aurantiaca Holland, 1893 ( Fig. 3 ). Diagnosis. The genus is characterized by an apically bifurcate uncus (sometimes with additional lateral processes), a curiously armed and sclerotized cucullus apex and a less sclerotized sacculus apex covered with chaetae. Аdditionally, male antennae bipectinate; eyes large, hemispheral, naked; fore tibiae simple, not robust, middle tibiae with an apical pair, hind tibiae with two pairs of spurs; vein R2 of forewings is stalked with R3+5 (venation type C, by Sotavalta 1964 ). Remarks. The genus was also isolated from Spilosoma s. lat. ( Dubatolov & Haynes 2008 ); originally, it was consisted of two not so closely related species with different wing pattern but a similar male genitalia structure. M. aurantiaca have additional lateral processes at the uncus apex, the wing pattern consisting of narrow brown bands on the background of speckled light brown wings; the tegulae lack dark spots. On the other hand, M. decemmaculata ( Rothschild, 1916 ) (see: Goodger & Watson, 1995 : 31, fig. 32, 41, fig. 139–140; Dubatolov & Haynes 2008 ) has spotted tegulae, light wings with a rounded discal spot and one or two rounded postdiscal spots. Because of the quite different wing pattern, it is excluded from the review.
