Nipponosega kurzenkoi Xu, He & Terayama, 2003

Nipponosega kurzenkoi Xu, He & Terayama, 2003: 195, holotype ♀ by original designation. Type locality: Mt. Jiulong, Suichang, Zhejiang Province, China (Type no. 944347, no type depository information, but likely Zhejiang University, Hangzhou). Not examined.

Diagnosis.

Nipponosega kurzenkoi is closely related to N. yamanei from Japan. It can be distinguished from N. yamanei by the fully testaceous mesopleuron, whereas it is blackish in N. yamanei (Fig. 2A ). Also, the frons is wider than in N. yamanei . The maximum interocular distance (measured at the lower end of the face) is 1.2 × longer than the width of frons (1.5-2.0 in N. yamanei ). Other diagnostic characters are as follows: body length 3.0 mm; head black, smooth with scattered punctures; lateral ocelli well separated from the inner margin of eye; mesosoma largely testaceous with mesoscutum and mesoscutellum black; pronotum smooth with scattered punctures; legs yellow; metasoma dark brown. Male is unknown.

Distribution.

China (Zhejiang).

Remarks.

Although the body color could be variable to some extent, no specimen of N. yamanei with completely testaceous mesopleuron has been found; a closely related species showing different distribution. The morphology of N. kurzenkoi should be evaluated in more detail to discuss their identification. However, diagnostic characters shown above do not overlap with those of N. yamanei . In the original description of N. kurzenkoi Xu et al., 2003, the evaluation of POD is different from the POD (= POL herein) used in Nagase (1995). The POD sensu Xu et al. (2003) is correspond to OOL herein.
