Orbamia pauperata Herbulot, 1966 Figs 13 , 31 , 49 , 67 , 81

Orbamia pauperata : Herbulot (1966): 221 (Holotype § in ZSM: gen. prep. ZSM G 14466; locus typicus: Madagascar: Betioky, southern shore of Tsimanampetsotsa).

Note.

So far, without BIN, holotype with short barcode fragment (BC ZSM Lep 81698).

Examined material.

2♂3♀ from Madagascar, including holotype (ZSM G 13619/♀).

Differential features

(COI sequences, photographs of adults and their genitalia see https://dx.doi.org/10.5883/DS-ORBAMIA): Adult: Forewing length: 10-12 mm. Upperside of wings: Ground colour pale grey. Underside: Ground colour beige, without yellow tinge, apical spot present on forewing. Male genitalia: Uncus digitiform, saccus shortly projecting, round, valva short, broad, tapered at tip, dorsal process stoutly sclerotised, with a conspicuous, very long spine at tip, aedeagus short (1.2 mm), cornutus very short (0.7 mm) and S-shaped at tip. Female genitalia: Lamella ante- and post-vaginalis developed as two separate, narrow, transverse sclerites, posteriorly bilobed, signum rhomboid, transverse ridge straight (0.25 mm).

Remarks.

Phylogenetically the most isolated species within this genus, based on large differences in morphology and genetics, the latter, however, just based on a short barcode fragment of the holotype.
