A taxonomic revision of the genus Mesophleps Hübner, 1825 (Lepidoptera: Gelechiidae) 3373 Author Li, Houhun Author Sattler, Klaus text Zootaxa 2012 2012-07-04 3373 1 82 journal article 1175­5334 Mesophleps aspina sp. nov. ( Figs 54 , 79 ) ♂ , Wingspan 11.5–14.0 mm. Labial palpus segment 2 black, distally with white ring, 3 white, apical one-third black, base with some black scales. Antenna whitish grey and light brown alternating. Forewing light yellow, basal half of costa white, black discocellular spot present, plical dash absent. Genitalia ♂ ( Fig. 79 ). Uncus rounded, ventro-anterior margin concave; gnathos hooks very short, fused at base; vinculum trapezoid, sometimes lateral corners prominent; posterior margin without sclerotized spine; phallus evenly tapered from swollen base towards long, almost straight apical portion, apex with long sharp point. Genitalia ♀ . Unknown. Remarks. M. aspina differs in the male genitalia from all other species of the albilinella -group in the absence of the characteristic pair of outwardly-directed spines on the posterior margin of the vinculum. Uncus and gnathos resemble those of parvella but the phallus is slimmer and has a long pointed, rather than blunt, apex. Biology. Host-plant unknown. Distribution. Thailand , Burma . Etymology. The specific name is derived from the Latin prefix a- (absent) and spina (spine), in reference to the absence of the outwardly-directed spines on the posterior margin of the vinculum in the male genitalia which otherwise are characteristic of this species-group.
