Figs. 12–17 View FIGURES 12 – 16 .
Adult habitus. General color pale brown patterned with dark brown. Head as wide as pronotum, with a distinct dark stigma covering ocelli and anterior frons; compound eyes dark and antennae dark brown ( Fig. 12 View FIGURES 12 – 16 ). Pronotum disc pale brown with brown rugosities and dark brown posterior and lateral margins ( Fig. 12 View FIGURES 12 – 16 ). Wing membrane subhyaline, veins dark; legs brownish to dark brown. Cerci pale ( Fig. 17).
Male ( Figs. 12–17 View FIGURES 12 – 16 ). Forewing length 13.0– 13.5 mm, hindwing length 11.5–12.0 mm. The posteromedial margin of tergum 7 with paired subtriangular processes, the processes each with blunt tip and margined by sparse spines. Terga 8–9 each with two small sensilla basiconica patches medially, tergum 9 bearing long hairs. Hemitergal processes slender with sharp apex ( Fig. 13 View FIGURES 12 – 16 ). Aedeagal tube sclerotized at base with a rectangular sclerite ventrobasally. Aedeagal sac as long as tube, ventrally with a pair of small, lateral, spinous lobes and two large, mesal, spherical lobes, the large lobes one spinous and another membranous; dorsobasally with two small, lateral, spinous lobes; dorsal and ventroapical surface of sac bearing large spines except for the membranous apex ( Figs. 14–16 View FIGURES 12 – 16 ).
Female. Unknown.
Type material. Holotype: male, China: Hainan Province, Mt. Wuzhishan , 18.4645 N, 109.3811 E, 17 May, 2012, Hai-Yan Wu, Ji-Rui Wang (Insect Collection of Yangzhou University, China). GoogleMaps
Distribution. China (Hainan).
Etymology. The species epithet refers to the six lobes of the aedeagus.
Diagnosis. The aedeagal sac of this species has four small, spinous lobes and two large, spherical lobes; dorsal and ventroapical surface of sac have large spines except for the membranous apex
Remarks. The new species is a member of the N. montivaga group. Aedeagal tube and sac of the new species is most similar to that of N. baisha Kong & Li, 2014 . However in N. baisha , the aedeagal sac has only one large, mesoventral lobe, and the relative location of the four small lobes differs from those of N. sexlobata (see figs. 1–2 in Kong et al. 2014). In addition, the new species can be distinguished by the distinct head pattern and the distinctive process on tergum 7.
