Crossodonthina bidentata Luo & Chen, 2009

New record

Figs 2, 11–13

Materials. Nine females, Mountain Wuyi National Nature Reserve, Fujian Province, China , on the roadside from Tongmuguan to Mountains Huanggang. Coordinates: 27°49’09”N, 117°43’17”E, alt. 1151–1156m, under humid leaves near rocks, leg. Ji-Gang Jiang, 14.v.2017 (J2017051402). Studied specimens are kept in the Key Laboratory of Zoology, Hunan University of Arts and Science (HUAS), Changde, Hunan Province, China .

Diagnosis. Body length 2.2–2.6mm. Two eyes per side on head; Di tubercles fused on Abd. V; mandible with two teeth and two rami.

Remarks. Most characters of the sampled material from Fujian Province agree with the specimens from Zhejiang Province, the type locality of C. bidentata . Even so, some obvious differences have been noticed. The body macro and mesochaetae are always smooth (Fig. 11) and the maxilla is tri-branched in Fujian’s individuals (Figs 12–13), whereas the body macro and mesochaetae are serrated, and maxilla is bi-branched in Zhejiang's specimens. The hypothesis that these distinct populations belong to different species cannot be ruled out, and further studies should be carried out to confirm or refute it.
