(Figs 11, 47)

Type material. 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.
