Tujuba, Tesfu Fekensa, Hausmann, Axel & Sciarretta, Andrea, 2020, Revision of the Orbamia Herbulot, 1966 group of genera with description of two new genera, ten new species, and two new subspecies (Lepidoptera, Geometridae, Ennominae, Cassymini), ZooKeys 929, pp. 53-77 : 53

Morabia Hausmann & Tujuba gen. nov.

Type species.

Morabia politzari Hausmann & Tujuba, sp. nov.

Etymology.

The name is an anagram of the sister genus Orbamia , similarly to the anagram used by Herbulot (1966) when transforming the name Boarmia to Orbamia .

Differential features

(COI sequences, photographs of adults and their genitalia see https://dx.doi.org/10.5883/DS-ORBAMIA). Adult: Male antennae ciliate-fasciculate, female antennae filiform. Palpi of both sexes broad, bushy scaled, length 1.0-1.5 times diameter of eye. Hind tibia of both sexes with two pairs of unequal spurs. Upperside of wings with discal spots vestigial, medial line zigzagging, terminal line conspicuous, zigzagging on all wings. Underside beige, with a few yellowish scales and a sharp black spot in forewing apex. Male genitalia: Uncus very short, rounded saccus shallowly projecting, dorsal process of valva strongly setose, valva long and narrow, curved, strongly setose, mainly at centre, aedeagus with long and stout cornutus. Female genitalia: Apophyses long and fine. Lamellae ante- and post-vaginalis membranous, ductus bursae straight, anteriorly membranous, posteriorly dilated and towards antrum strongly sclerotised, corpus bursae membranous, pyriform, signum absent.

Genetic data and phylogeny.

The maximum likelihood analysis of COI barcode data suggests the monophyly of the genus Morabia gen. nov. and an isolated position from ( Rabomia gen. nov. ( Pycnostega + Dorsifulcrum )) and from genus Orbamia (cf. Table 1 , Fig. 85 ). However, phylogenies at genus level need to be considered with caution, when they are inferred from COI data.
