Etymology: The specific epithet is taken from the Latin a (= not) + concinnus (= symmetry), in reference to the asymmetrical hypandrium of this species.
Description: Male. Head. White in ground colour; vertical and orbital markings large, blackish brown; coronal suture black; frontal suture bordered with blackish brown band dorsally; frons with two pairs of pale brown bands; gena blackish brown; eye black, IO/D = 1.1; ocelli white, ocellar field black; antennal socket bordered with blackish brown band; postclypeus with eight rows of blackish brown spots, fused with each other ventrally, forming large marking, lateral margin of postclypeus blackish brown; anteclypeus blackish brown. Antenna pale brown, scape and pedicel darker. Mouth parts blackish brown.
Thorax. Prothorax blackish brown. Mesonotum brown; anterior surface of scutum blackish brown; anterior margin of lateral lobe of scutum black; posterior part of median lobe white; lateral lobe with paler oval part medially; anterior margin of scutellum blackish brown; postnotum brown. Metanotum brown, with pale oval part on posterior region of each lateral lobe of scutum; medial lobe with white spot medially; anterior margin of scutellum blackish brown. Meso- and metapleurites blackish brown except membranous region white and mesopleuron with longitudinal pale brown band.
Legs. Blackish brown; tibiae paler; fore and middle femora with pale brown portions medially.
Forewing ( Fig. 36A View Figure 36 ). Spots in cell a 1 apparent. Opposing spots in cell r large, almost fused with each other. Proximal band broad in cell CuP but narrower in cell CuA, broadly interrupted just beyond fork of M + Cu, cell CuA including pale spot. Median spots dense, some spots fused with each other, forming larger markings. Distal band faint, broad in cell r 5, fragment of band in cell r 3 small. Spot on roof of cell m 3 small, darker than marginal cloud. Submarginal spots apparent; spots in cell r 1 and r 3 smaller than others. Marginal clouds apparent and dark. Hindwing. Hyaline with faint brown markings in cell CuP; veins brown.
Abdomen. White. Terminalia. Clunial arm ( Fig. 37A View Figure 37 ) long and narrow, sickle-like in shape and forming free process apically. Epiproct ( Fig. 37A, B View Figure 37 ) chair-shaped, postero-dorsal margin with strongly projected transversal ridge; epiproct lobe small, much broader than long, narrowing dorsally, posterior surface with well-developed swelling. Paraproct ( Fig. 37A View Figure 37 ): ventro-lateral band short, triangular; distal process long, directed upward. Hypandrium ( Fig. 37C View Figure 37 ): left process needle-like, almost straight, directed postero-internally; right process lamellate; median tongue small but long, length/width ª 2.5, gradually narrowing to rounded apex, dorsal surface covered by weak denticles. Phallosome ( Fig. 37D View Figure 37 ): pseudoparameres long, needle-like. Aedeagus strongly projected dorsally, triangular, sclerotized region extending to endophallus opening. Phallobase broadest in the middle, anterior margin rounded.
