Darpa dealbata (Distant, 1886) , reinstated status

Tagiades dealbata Distant, 1886 (type locality Malay Peninsula) has been treated by Evans (1949) as a subspecies of Darpa pteria (Hewitson, 1868) (type locality Philippines). In addition to comparatively (among Darpa Moore, [1866] species) large genetic distances revealed by a genomic tree ( Fig. 3 ), COI barcodes of these two taxa differ by 7% (46 bp), and genitalia differ per Evans’ sketches (1949) and more detailed illustrations ( Huang et al. 2019), most strongly in the shape of ampulla process and the end of harpe. For these reasons, we reinstate Darpa dealbata (Distant, 1886) as a species distinct from D. pteria .

Triskelionia Larsen and Congdon, 2011 belongs to Tagiadini Mabille, 1878 and is confirmed as a valid genus

Proposed for Hyda tricerata Mabille, 1891 (type locality Sierra Leone) at that time placed in the Celaenorrhinini Swinhoe, 1912 genus Sarangesa Moore, [1881] (type species Sarangesa albicilia Moore, [1881] , which is currently a subspecies of Nisoniades dasahara Moore, [1866] ), Triskelionia Larsen and Congdon, 2011 was left in Celaenorrhinini ( Larsen and Congdon 2011) . We sequenced two syntypes of Triskelionia tricerata in the ZMHB collection (NVG-18055E03 and 4). They form a clade distinct from others and sister to Tapena Moore, [1881] (type species Tapena thwaitesi Moore, [1881] ) plus Gerosis Mabille, 1903 (type species Coladenia hamiltoni de Nicéville, [1889] , which is a junior subjective synonym of Satarupa phisara Moore, 1884 ) with strong support ( Fig. 3 ). All these genera are within Tagiadini Mabille, 1878 , and away from Celaenorrhinini as judged by the monophyly with the corresponding type genera of these tribes. Therefore, we transfer Triskelionia from Celaenorrhinini to Tagiadini, new placement, and confirm its validity as a genus.
