( Figs. 18–33 )

Type material. Holotype: ♂ ( NWAFU), China: Hainan Prov., Bawangling, 25 May 1983, Yalin Zhang , light trap ( NWAFU) . Paratypes: 1♂, Hainan Prov., Liangyuan , China, 1 June 1983 ; 1♂, Guangdong Prov., Dinghu mountain , Zhaoqing, 17 July 1985, Yalin Zhang ( NWAFU) .

Description. Size. male 3.4–3.7mm.

Male. Ground colour yellow to yellowish-green. Vertex beige to orange, with longitudinal creamy streak along coronal suture, bordering eye with creamy patch basally at each side of vertex; ocelli surrounded by small creamy patches; coronal suture beige. Eyes blackish-brown. Pronotum with anterior margin and adjacent arcuate area with irregular creamy patches. Scutellum with quadrate creamy patch medially, with lateral creamy patch on each side of midline caudad of scutoscutellar sulcus. Abdomen orange.

Abdominal apodemes of segment 3rd reaching to end of segment 4. Male pygofer with about 6-9 rigid microsetae on each side of pygofer lobe; dorsal lobe without setae; ventral pygofer appendage with apical one-third sinuate, with numerous minute teeth at ventral side subapically. Anal tube process curved caudoventrad apically and tapered to acute apex. Subgenital plate with 6-8 macrosetae in basal group, 14-17 marginal spine-like setae arranged in two groups, 19-21 lateral macrosetae and 2 irregular rows of fine microsetae. Paramere with apex truncate and bearing 11 teeth preceded by about 10 long fine setae. Connective fused to aedeagus, stem broad in profile. Aedeagal shaft with pair of spinose processes two-thirds distance from base to apex and a triangular, lamellate process on each side apically dentate basally at outer margins, gonopore dorsal, subterminal.

Female. Unknown.

Etymology. The name is an adjective derived from the Latin word “lamellatus” meaning leaf-like, refering to the shape of the aedeagal apex.

Distribution. Known only from the type locality in Hainan and Guangdong Provinces in southern China.
