Seriana menglaensis Song & Li sp. n. Figures 1-10

Description.

General color fuscous. Head (Fig. 1) with vertex dirty yellow, with an irregular brown spot at anterior margin medially; eyes black. Pronotum (Fig. 1) with five whitish oval impressed patches near anterior margin. Forewing light testaceous, without markings; brochosome field blackish brown.

Head (Fig. 1) distinctly narrower than pronotum; vertex bluntly rounded.

Abdominal apodemes (Fig. 2) small, acuminate apically, not extended beyond hind margin of 3rd sternite.

Pygofer lobe (Fig. 3) broad, with distinct oblique dorsolateral internal ridge, numerous macrosetae at lower basal angle. Pygofer dorsal appendage very long and fused with dorsal margin of pygofer. Subgenital plate (Fig. 4) with three long macrosetae and short rigid setae at upper margin subbasally; several microsetae scattered on apical portion. Style (Fig. 5) long, apex truncate; preapical lobe large. Connecitve (Fig. 8) Y-shaped, stem strong, central lobe absent. Aedeagus (Figs 6, 7) with shaft long and straight, with two pairs processes, one pair very long, arising from basolateral part of shaft; another pair placed apically very short, lamellate; gonopore at apex, on ventral margin, dorsal apodeme short, weakly expanded.

Body length males 3.2 mm.

Type material.

Holotype, male, China: Yunnan Prov., Mengla County, at light, 23 July 2008, coll. Yuehua Song. Paratype: one male, same data as holotype.

Remarks.

The new species is similar to Seriana ochrata Dworakowska (1971), but can be distinguished from the latter by the aedeagal shaft longer and straighter, similar in width throughout length in ventral view; the paired long processes arising from the base of aedeagal shaft, not at midlength and the dorsal apodeme small.

Etymology.

The new species is named after its type locality: Mengla.
