TYPE MATERIAL. — Holotype. Madagascar • ♂; Toliara Province, Massif du Makay ; 21°36.144’S, 45°06.738’E; 11.I.2011; V. M. Gnezdilov leg.; ZIN. GoogleMaps

Paratype. Madagascar • ♂; Toliara Province, Massif du Makay ; 243 m; 21°36’236”S, 45°06’464”E; forêt sèche; 12.I.2011; D. Ouvrard leg.; MNHN-EH-EH24763 .

ETYMOLOGY. — The species name is referring to similarity in face coloration with Oryx gazella (L.) (Mammalia).

DIAGNOSIS. — Aedeagal shaft with two spine-shaped processes subapically on right side and one spine-shaped subapical process on left side and with two longer spine-shaped processes below on left side ( Fig. 6D, E View FIG ).

TAXONOMIC RELATIONSHIPS. — Very close to L. declinatus Wang, Dietrich & Zhang, 2018 in coloration, but well distinguished by lighter forewings and dense brown dots on pronotum and by fewer spiny processes of aedeagus – five processes in comparison to 12 in L. declinatus .

DESCRIPTION

Structure

Structure as mentioned for the genus. Crown narrow and long, 1.5 times as long at midline as wide basally. Pronotum nearly as long as crown medially. Mesonotum 1.5 times as long as pronotum medially. Second metatarsomere with two spines laterally and one platella between them ventroapically. Apodemes of second abdominal segment rather long and wide ( Fig. 6C View FIG ).

Coloration ( Fig. 4A, B View FIG )

Face with frontoclypeus light yellow, with two longitudinal black stripes laterally; lorae black, with light yellow margins; anteclypeus light yellow, with wide lateral black stripes converging subapically; black spot under each eye; ocelli dark brown; antennae light yellow. Legs light yellow. Crown brown, with wide longitudinal black stripes on the sides of median carina. Pronotum black, with dense light brown dots, sometimes fused in the areas; paranotal lobes of pronotum light yellow, each with black spot in its lower part. Mesonotum black, with sparse brown dots and with four black spots on brown yellowish background medially. Episternae and epimerae of thorax black, with light yellow margins. Scutellum with brown yellowish apex. Forewings with dark brown to black veins, brown to dark brown cells of corium and clavus in its basal 2/3 of length, with brown dots on veins in apical third of wing and with two separated light brown yellow areas – one narrow along the costal margin from the basal cell to apical third of inner anteapical cell and another one, wide, from costal margin throughout outer anteapical cell; appendix of forewings cinereous. Hindwings cinereous, with light spot on costal margin and dark brown veins. Hind tibiae with black apices of spines. Claws dark brown to black. Abdominal tergites dark brown to black, each with pair of large orange yellow spots laterally running from its anterior margin to its yellow posterior margin. Genital block dark brown. Abdominal sternites dark brown to black, with brown yellowish hind margins.

Male genitalia ( Fig. 6 View FIG )

Anal tube 1.5 times as long as wide, flattened ventrally( Fig.6F View FIG ). Anal column short. Pygofer lobe triangularly elongate, with an additional small lobe on apical angle under the anal tube and with ventral lobe in its basal half ( Fig. 6B View FIG ). Subgenital plate long and narrow, with around 12 microsetae apically and with long setae on the main surface. Aedeagus asymmetrical, shaft long and narrow, curved, with small hook apically ( Fig. 6D View FIG ), with two spine-shaped slightly curved processes subapically on right side and one spine-shaped slightly curved subapical process on left side and with two longer slightly curved spine-shaped processes below on left side ( Fig. 6E View FIG ), gonopore probably subapical. Styles elongate, narrowing apically, with rounded apices ( Fig. 6G View FIG ). Connective arcuate ( Fig. 6H View FIG ).
