Balclutha bidentifurcata , sp. nov.

( Fig. 4 ; Plate 1, C)

Description. Length (including tegmen). Male: 2.6–2.9 mm; female: 3.0– 3.2 mm.

Stramineous. Vertex, frontoclypeus, pronotum and scutellum with pink to reddish markings; ocelli and eyes pink; distal and claval region of forewings smoky brown. Head equal in width to pronotum, vertex anterior margin rounded, uniform in length. Hind femur setal formula: 2.1.1.

Male genitalia. Pygophore moderately long with group of macrosetae at mid-length. Valve broadly triangular. Subgenital plates shorter than pygophore, apical processes arising subapically from dorsal surface, long. Style with apical apophysis robust, curved slightly laterally; preapical lobe well developed. Connective with stem shorter than arms, apex distinctly broadened and slightly emarginate. Aedeagus simple, dorsal apodeme well developed; shaft moderately slender, curved dorsally, bifurcated apically, each apical appendage with two small teeth subapically, gonopore apical.

Material examined. HOLOTYPE: male, China, Hainan Prov., Mt. Bawangling, 10.vi.2007, Coll. Duan Yani. PARATYPES: 8 males, 6 females, same data as holotype; 1 female, China, Hainan Prov., Yacheng County, 9.vi.1983, Coll. Zhang Yalin (NWAFU); 1 male, same data as holotype (BMNH).

Distribution. China (Hainan).

Remarks. This species is similar to B. rieki , but can be distinguished from the latter by the head and thorax with pink to reddish markings and the aedeagal shaft with apical processes longer, and each appendage with two small teeth subapically.

Etymology. The term “ bidentifurcata ” refers to the bifurcated aedeagal shaft, each appendage with two small teeth subapically.
