Loeia sinuata sp. nov.

( Figures 1K , 5E–H )

Diagnosis. This species resembles L. articulata in the structure of the genital capsule but differs in having the aedeagal shaft with asymmetrical distal processes and the basal process elongate, sinuate and fused to the base.

Description. Body length of male 5.5 (female unknown). Head in dorsal view with crown no longer medially than next to eye, 1.8× wider at base than medial length, anterior and posterior margins parallel. Male pygofer ~3.5× longer than maximum height, ventral spine well developed, extended dorsomesad and slightly posterad. Subgenital plate not extended to midlength of pygofer, laterally convex basal section as long as concave distal section. Style moderately long, preapical lobe short and obtuse, apex robust, digitiform, curved slightly laterad. Aedeagus with dorsal apodeme very short, rounded, with long, slender, sinuate, weakly pigmented process arising near base of shaft and extended posterad slightly beyond shaft apex; shaft asymmetrical, nearly straight, gradually broadened in ventral view, with preapical process curved ventrad then anterad with adjacent short lobelike process; gonopore apical.

Etymology. The species name refers to the sinuate basal process of the aedeagus.
