Hypnogyra sinica nov.sp.

M a t e r i a l s t u d i e d: Holotype: Jiangsu, Huaian city, Liannshui coun., Gaogou town , X. Z. Yuan 30.VI.2009 ( SNUC); paratypes: same data, 1, 3 ( SNUC), 2, 1 (cB).

D e s c r i p t i o n: Length of body about 6 mm; from anterior margin of head to posterior margin of elytra: 3,4 mm. Head and pronotum black (in some paratypes pronotum reddish brown), elytra reddish brown, partially infuscate; abdomen reddish brown dark; antennae and legs brown. Body entirely without micro-sculpture, shiny. Forebody as in Fig. 74 , a litte longer than that of H. henanica nov.sp. Head with sparse, well visible punctures, apart a wide median strip. Pronotum with dorsal series of 8-9 deep, well visible punctures and lateral series of 6-7 irregular punctures. Elytra with fine puncturation, arranged in 6-7 series. Abdomen with dense, not particularly fine puncturation on the sides.

Posterior margin of the 6° visible abdominal tergite similar to that of H. henanica , with a series of dense, short and rounded protrusions. Posterior margin of the 6° visible abdominal sternite prolongated in a lobe ( Fig. 75 ). Tergite and sternite of the male genital segment as in Figs 76-77 . Aedeagus ( Fig. 78 ) a little longer than that of H. henanica (fig.), 1,18 mm long, evidently swollen, with longer, asymmetrical parameres; inner sac similar to that of H. henanica , but wider, covered by different scales ( Fig. 79 ).

E t y m o l o g y: The specific epithet refers to the Latin sinicus- a- um (chinese).

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 Jiangsu.

Note This species differs from H. henanica by size (longer forebody), shape of forebody (in particular head and pronotum), colouration (darker), puncturation and aedeagus. In Sichuan (Shaanxi) is present another species: H. sichuanica BORDONI 2003b .

In the past ( BORDONI 2003f) I had ascribed to H. tubulus ( SHARP 1889) some specimens from Korea., that in fact belong to H. hofmanni ( BERNHAUER 1928), species cited from Hebei and Heilongjiang ( SMETANA 2004).
