Holotype ( Figs 11 , 47 ): male, [ Indonesia ] “ Sumatra Aceh | Westcoast | Kuala Dou near | Calang , 100 m | 20.–26. II 1996 | leg. A. Kallies ” / “Slide | AV7324♁ | A. Volynkin ” (MWM/ ZSM , ex CKC ). Diagnosis . The forewing length is 13.5 mm in the male holotype . The male genital capsule of L. paraliaka is similar to L. diehli but readily differs in the broader sacculus with a markedly shorter and proximally broader distal saccular process, which is more S-like curved distally. The phallus of the new species is somewhat longer than in the congener (in proportion to the tegumen-vinculum complex length). Compared to L. diehli , the vesica of L. paraliaka is distally broader, has shorter and semiglobular medial dorsal diverticula (they are utricular in the congener), and a broader distal diverticulum bearing two larger terminal cornuti (whereas L. diehli has a single terminal cornutus). The female is unknown. Distribution . The new species is currently known only from its type locality in coastal north-western Sumatra . Etymology . The specific epithet is derived from the Greek ‘παραλιακός’ meaning ‘coastal’ and refers to the occurrence of the new species in the coastal area of north-western Sumatra . The name is a noun in the nominative singular in apposition.
