Orbamia ocellata (Warren, 1897) stat. nov. Figures 9 , 27 , 45 , 63 , 77

Lepiodes ocellata : Warren (1897): 94 (Syntypes 5♂1♀ in NHMUK; locus typicus: South Africa: Bathurst; [north-eastern Zambia]: Mpeta, Loangwa River [Luangwa], off the Zambesi [close to the border with northern Malawi]).

Note.

Synonym of O. octomaculata according to Scoble (1999) but the type series of ocellata belongs to two different species. Herewith we designate the red-ring-labelled male specimen from Zambia, Mpeta, as lectotype to fix the identity of the name and to stabilise nomenclature. The taxon is herewith upgraded from synonymy to species rank (stat. nov.), based on the below mentioned differences in DNA barcodes and genitalia. Pattern of upper- and underside of wings of the lectotype exactly matches that of the examined material from Tanzania, partly collected in closely adjacent localities to the type locality (e.g., Ruvuma and Iringa provinces).

Examined material.

Differential features

(COI sequences, photographs of adults and their genitalia see https://dx.doi.org/10.5883/DS-ORBAMIA): Adult: Forewing length: 8.5-12 mm. Upperside of wings: Ground colour pale grey with slight brown suffusion, pattern brown with slight orange tinge. Underside: Ground colour whitish, orange between veins, apical spots on forewing conspicuous, sharply bordered, on hindwing terminal fascia usually diffuse, rarely restricted to apex. Male genitalia: Uncus narrow, digitiform, valva straight, broad, dorsal process with conspicuous, stout hook at tip, cornutus narrow and very long (2.8-3.0 mm). Female genitalia: Apophyses stout, apophyses anteriores comparatively long (2/3 length of apophyses posteriores), lamella ante- and post-vaginalis fused, oval, comparatively broad (length 0.7 mm, width 0.5 mm), signum weakly sclerotised, small, transverse ridge straight (0.2 mm).
