Clavicornaltica vietnamensis new species

( Figs. 8 , 18 , 23–26 )

Description. Body length 1.06–1.08, 0.91–0.93 width, chestnut brown. Vertex relatively sparsely covered with small punctures. Midfrontal sulcus absent. Elytron less convex in lateral view ( Fig. 8 ), with 9 rows of punctures, more prominent in middle. Metafemora 1.40 times longer than wide, with maximum width nearly in middle. Metatibia 5.7 times longer than wide, with maximum width near middle (in ventral view). Proportions of metatarsomeres (starting with first) as follows: 11:4:3:7. Intercoxal prosternal process low, not reaching beyond procoxae. Metasternum with middle as flat as sides. Median lobe of aedeagus narrowing apically, apex seems symmetrical ( Fig. 18 ). Female wingless. Spermatheca with very long duct and pump more than two times shorter than receptacle ( Fig. 23 ). Receptacle narrower than pump. Tignum wider anteriorly than posteriorly ( Fig. 24 ). Vaginal palpi situated close to each other along most of their length ( Fig. 24 ).

Type material. Holotype ɗ. Labels:1) N. Vietnam, Tamdao , 15–23.IX.1997, A. V. Napolov; 2) Zool. Inst. St.Petersburg; 3) Holotype Clavicornaltica vietnamensis sp. nov. des. A. Konstantinov and C. Duckett ( ZMAS); Paratype (Ψ) with the same label as holotype ( USNM).

Diagnosis. Clavicornaltica vietnamensis can be distinguished from C. tamdao by its lighter color, distinct elytral punctations and spermatheca with very long duct and pump less than half as long as receptacle.

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