Morphostenophanes jendeki jendeki Masumoto, 1998: 308 (type locality: Heishui [located on eastern slope of Yulong Snow Mountain], Yunnan, China), fig. 2, 15–17; Löbl et al. 2008: 344; Gao & Ren 2009: 312.

Type material examined. Paratype labelled: ‘ CHINA, YUNNAN prov. 18.6.– 4.7. 1993 heishui= 35km N Lijiang 27, 13 N; 100, 19 E let. S. Becvar // Coll. Masumoto 2001 // Paratype Morphostenophane jendeki MASUMOTO [handwritten in pink label with underlines]’ (male, NSMT, Fig. 43C ). Examined through two photographs taken by Kimio Masumoto .

Comments on type material. The type series of M. jendeki jendeki consisted of 21 specimens. According to the original description, the holotype is deposited in NMP (= NMNHP). Depository of paratypes was not mentioned in the original description, but at least part of them are currently deposited in NSMT.

Additional material examined. CHINA: Yunnan: 1♂ ( CZDY), Lijiang City, Yulong Snow Mountain , 27°8’20.40”N, 100°13’37.20”E, 3258 m, bark spray in conifer forest, 2012.viii, native collector ; 1♀ ( CZDY, a sample of muscle tissue was preserved in 99.7% ethanol at –18 °C), Lijiang City, Yulong Snow Mountain , 27°11’13.20”N, 100°13’1.20”E, 2012.viii, native collector .

Comparative notes. Morphostenophanes jendeki jendeki resembles M. crassus . Detailed comparison is provided in the comparative notes of M. crassus .

Comments. On the additional male specimen, a pair of small, shallow impressions on the pronotal surfaceand a deep impression on the posterior middle of sternite III was observed. These characters were not mentioned in the original description. The pronotal shape depicted in Fig. 34A seems accordant with the specimen illustrated in the original publication ( Masumoto 1998, Fig. 2 ), and the form depicted in Fig. 34C (Paratype) resembles the form of M. jendeki similis . Therefore, whether pronotal shape is reliable for distinguishing M. jendeki jendeki and M. jendeki similis requires study of more specimens.

Distribution. ( Map 1 , 3) CHINA: Yunnan.
