Metolinus manfei nov.sp.

M a t e r i a l s t u d i e d: Holotype: Yunnan, Manfei, Nabenhe conv., Li & Tang 10.I.2004 ( SNUC); paratypes: same data, 9.I.2004, 1 ( SNUC); same data, 12.I.2004, 1 (cB).

D e s c r i p t i o n: Length of body about 5 mm; from anterior margin of head to posterior margin of elytra: 2,8 mm. Brown black with 6° visible abdominal segment and genital segment reddish (paratypes reddish brown); antennae and legs brown; tarsi reddish. Similar in shape and size to M. shanicus from which differs in colouration (elytra entirely unicolor). Head with transverse micro-striation. Pronotum wider than that of M. shanicus , with largely rounded anterior angles and sinuate sides; dorsal series of 6 and lateral series of 4 small punctures. Elytra longer and wider than pronotum, with marked humeral angles. Surface with very fine and sparse punctures, arranged in some series. Abdomen with transverse micro-striation and fine, sparse puncturation.

Posterior margin of 6° visible abdominal tergite slightly rounded; posterior margin of 6° visible abdominal sternite with a wide median emargination ( Fig. 39 ). Tergite and sternite of the male genital segment as in Figs 40-41 . Aedeagus ( Fig. 42 ) 0,9 mm long, ovoidal, narrow and elongated, with characteristic distal plate and very narrow and long parameres; inner sac with a long spine and a small, distal spine.

E t y m o l o g y: The specific epithet refers to the type locality, as a noun in apposition.

G e o g r a p h i c a l d i s t r i b u t i o n: The species is known only from the type locality, in Yunnan.

N o t e: This species is related to the M. almorae -group ( BORDONI 2002) by the external characters, but differs from all the known species from India, Sri Lanka, Thailand, Borneo, by the inner sac of the aedeagus.

The Metolinus CAMERON 1920 from China, apart the cited M. shanicus , are the following: M. planulatus ( SHARP 1889) (Fujian) , M. hayashii BORDONI 2002 , M. yunnanus BORDONI 2002 , M. gardneri ( CAMERON 1945) , M. binarius ZHOU & ZHOU 2011

(Yunnan), M. xizangensis ZHOU & ZHOU 2011 (Tibet) , and M. emarginatus ZHOU & ZHOU 2011 (Sichuan) . All the males of the species described in these pages have oblong and narrow aedeagus and the inner sac with one-two long spines.
