Popis: Dentaneura biangulata Lin & Zhang sp. nov. (Figs 1a–d, 3) Description. Crown with pair of dark spots. The other characters as in generic description (Figs 1a, b, c, d). Abdominal apodemes not extended to sternite IV (Fig. 3b). Anal tube short, with poorly developed appendage (Fig. 3a). Pygofer with few short microsetae near posterior margin and group of macrosetae at cephalo-ventral angle (Fig. 3a). Pygofer dorsal appendage not exceeding posterior margin of pygofer lobe (Figs 3a, c). Subgenital plate with about 5 macrosetae scattered on lateral surface near outer margin, 2 angled processes apically, 3–4 peg-like on each angled process (Fig. 3a). Connective V-shaped, manubrium short (Fig. 3d). Aedeagal shaft compressed distinctly, gourd-like in ventral view (Figs 3g, h). Measurement. Male 2.65–2.75mm, female 2.70mm. Material examined. Holotype: ♁, CHINA, Guizhou Prov., Qiannan, 1950m, 2013.VII.27; Paratypes: 4♁ 1♀, same data as holotype. Remarks. This new species is similar to Dentaneura henanensis Song, Li & Dai, but has the pygofer dorsal appendage not exceeding the posterior margin, the subgenital plate with 2 angled processes apically, and the aedeagal shaft obviously expanded medially in ventral view. Dentaneura henanensis Song, Li & Dai has the pygofer dorsal appendage distinctly exceeding the posterior margin, the subgenital plate with only 1 angled process apically, and the aedeagal shaft slightly expanded medially in ventral view. Etymology. The specific epithet is derived from Latin prefix “bi-” and the Latin word “angulatus”, referring to the subgenital plate with 2 angled processes apically.
