Japanagallia lamellata sp. nov.

( Figs 3–4 , 6 , 14–21 )

Measurements. Male 3.87–4.05 mm long, head 1.33–1.41 mm wide across eyes, pronotum 1.21–1.27 mm wide. Female 4.0– 4.12 mm long, head 1.33–1.40 mm wide across eyes, pronotum 1.25–1.31 mm wide.

Description (holotype). Ground color chocolate brown to dark brown. Vertex ( Figs 3, 4 ) pale brown with two black maculae closer to median line than to compound eye. Face ( Fig. 6 ) fulvous with pale dark median stripe joined to large black area occupying frontoclypeus, anteclypeus, lorum, and inner areas of genae. Ocelli ( Fig. 6 ) yellowish brown. Pronotum ( Fig. 3 ) dark brown except narrow pale brown lateral and posterior margins. Mesonotum black; mesoscutellum ( Fig. 3 ) with pale brown lateral stripes joined to narrow ones of mesonotum. Forewing ( Figs 3, 4 ) dark brown at basal half, apex chocolate brown, claval veins pale brown, with white waxy area at upper part of outer apical cell. Legs yellowish brown.

Male genitalia. Pygofer ( Fig. 14 ) elongate in lateral view, dorsoposterior corner with directed spine, caudal margin medially concave. Style ( Fig. 15 ) short and stout, apex with strongly semicircular process directed laterally. Connective ( Figs 16, 17 ) of uniform width in ventral view, expanding at base in lateral view. Aedeagus ( Figs 18–20 ) U-shaped in lateral view, shaft narrow and long with two triangular processes apically, two arcuate, lamellate processes near base, aedeagus ventrally prolonged, with terminal rodlike process with pointed apex, gonopore apical.

Female. Similar in coloration as in male, but it’s heavily colored, most of face, mesonotum, mesoscutellum and claval veins of forewing black.

Female genitalia. Ovipositor slightly projecting beyond pygofer. Seventh sternite approximately half as long as wide, posterior margin strongly concave medially.

Material examined. Holotype: male, China, Hainan, Prov.: Jianfengling (18°23΄N, 108°26΄E), 900 m, 17 July 2007; paratypes: 2 males and 2 females, same data as holotype; 1 male, China, Hainan, Prov.: Diaoluoshan (18°45΄N, 109°22΄E), 700 m, 25 July 2007, all collected by Zhang Bin.

Host plant. Unidentified ferns.

Remarks. The species resembles Japanagallia spinosa sp. nov. externally, but differs in the dorsoposterior corner of pygofer extended as a pointed process, aedeagal shaft U-shaped with two lamellate processes situated near base.

Etymology. The specific name, lamellata , refers to the lamellate processes of the aedeagal shaft.
