Loeia biclavata sp. nov.

( Figures 1B , 2F–J )

Diagnosis. This species resembles L. decidua in the structure of the genital capsule and having a pair of lateral preapical processes on the aedeagus, but has the processes much longer, curved anterad and capitate.

Description. Body length of male 4.8 mm (female unknown). Head in dorsal view with crown slightly longer medially than next to eye, 1.6× wider at base than medial length. Male pygofer ~3.5× longer than maximum height, with short, toothed ventral process extended ventromesad and curved posterad. Style relatively short and slender, preapical lobe obtusely rounded, apex tapered and abruptly curved laterad. Aedeagus with dorsal apodeme very slender and moderately long in lateral view; shaft somewhat compressed, curved dorsad, with obtuse preapical dorsal angle, posteroventral margin denticulate, pair of slender, clavate processes arising just below gonopore and curved anterolaterad; gonopore preapical on posterior surface.

Etymology. The species name refers to the two preapical club-like processes of the aedeagus.
