Vitronura paraacuta Wang, Wang & Jiang, 2016

Vitronura paraacuta Wang, Wang & Jiang, 2016: 183-196, figs 1-7 (China)

Material.

Two females, submature, on slides, five specimens in alcohol, Maolan National Nature Reserve, Libo County, Guizhou Province, China, 25°16.400'N, 107°53.864'E, ca. 880 m above sea level. 19 July 2015. Collected by Cheng-Wang Huang, Yan Liang, and Ai-Min Liu.

Diagnosis.

The characters of the specimens from Maolan are consistent with those of Vitronura paraacuta Wang, Wang & Jiang, 2016: body tubercles well differentiated, head with 14 tubercles (only cephalic tubercle L fused to So), 2+2 depigmented eyes, mandible with four teeth, maxilla styliform, tubercles Fr and Oc with three chaetae each, and claw with an inner tooth.

Remarks.

The arrangement of the dorsal body tubercles and numbers of chaetae on dorsal tubercles of V. paraacuta are very similar to those of V. dentata Deharveng & Weiner, 1984 from Korea. However, V. paraacuta can be differentiated from V. dentata by almost smooth body macrochaetae, four teeth on mandible, chaetae Di2, De2 on cephalic tubercle De and chaeta Oca on cephalic tubercle Oc being mesochaetae (vs serrated body macrochaetae, three teeth on mandible, chaetae Di2, De2 on cephalic tubercle De and chaeta Oca on cephalic tubercle Oc being microchaetae in V. dentata ). The distribution of V. paraacuta is given in Fig. 16.
