Dentaneura biangulata Lin & Zhang View in CoL sp. nov.
( Figs 1a–d View FIGURE 1 , 3 View FIGURE 3 )
Description. Crown with pair of dark spots. The other characters as in generic description ( Figs 1a, b, c, d View FIGURE 1 ).
Abdominal apodemes not extended to sternite IV ( Fig. 3b View FIGURE 3 ). Anal tube short, with poorly developed appendage ( Fig. 3a View FIGURE 3 ).
Pygofer with few short microsetae near posterior margin and group of macrosetae at cephalo-ventral angle ( Fig. 3a View FIGURE 3 ). Pygofer dorsal appendage not exceeding posterior margin of pygofer lobe ( Figs 3a, c View FIGURE 3 ). 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 View FIGURE 3 ). Connective V-shaped, manubrium short ( Fig. 3d View FIGURE 3 ). Aedeagal shaft compressed distinctly, gourd-like in ventral view ( Figs 3g, h View FIGURE 3 ).
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.
