Clavicornaltica longsheng new species

( Figs. 5 , 10, 12 , 27–31 )

Description. Body length 1.45–1.48 mm, width 1.32–1.34 mm, dark brown. Vertex relatively sparsely covered with small punctures. Midfrontal sulcus absent. Pronotum impunctate. Elytron very convex in lateral view [length (from apex to connection with pronotum) to width ratio 1.41 ( Fig. 5 )] with 9 rows of nearly indistinct punctures. Mesofemora broad in middle ( Fig. 12 ). Metafemora 1.32 times longer than wide, with maximum width near middle. Metatibia 5.5 times longer than wide, with maximum width apical of middle (in ventral view). Proportions of metatarsomeres (starting with first) as follows: 12:7:5:11. Intercoxal prosternal process high, reaching beyond procoxae. Metasternum with middle raised as high ridge ( Fig. 10 ) continuing between mesocoxae. ( Fig. 12 ). Vaginal palpi widely separated ( Fig. 28 ), length less than 2x total width. Spermatheca with very long duct and with pump shorter and wider than receptacle ( Fig 27 ). Female wingless. Male unknown.

Type material. Holotype Ψ. Labels: 1) China. NE Guangxi, 10km S Longsheng (25°48' 00" N 110°00' 00" E), 1000m litter 16.VI.1995 leg. S. Kurbatov; 2) Holotype Clavicornaltica longsheng sp. nov. des. A. Konstantinov and C. Duckett ( ZMAS). Paratypes 2 Ψ with the same labels as holotype ( ZMAS, USNM).

Diagnosis. Clavicornaltica longsheng can be distinguished from all other Clavicornaltica species by the unique shape of the intercoxal prosternal process and metasternum ( Fig. 10 ) and by the widely separated, short vaginal palpi ( Fig. 28 ). See key below for more distinguishing characters.

Etymology. The specific epithet is a noun in apposition based on the type locality.
