Clavicornaltica tamdao new species

( Figs. 2–4 , 7 , 13–15 , 17 , 19–22 )

Description. Body length 0.86–0.95 mm, width 0.83–0.84 mm, dark brown. Vertex relatively sparsely covered with small punctures. Midfrontal sulcus absent. Elytron less convex in lateral view ( Fig.7 ), with 9 rows of punctures, more prominent in middle. Metafemora 1.35 times longer than wide, with maximum width basal to middle. Metatibia 6 times longer than wide, with maximum width apical to 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 nearly parallel sided, apex seeming asymmetrical ( Fig. 17 ). Females wingless. Spermatheca with very short duct and pump shorter than receptacle. Receptacle wider than pump ( Fig.19 ). Tignum poorly sclerotized posteriorly ( Fig. 20 ). Vaginal palpi widely separated ( Figs. 20, 22 ).

Type material. Holotype ɗ. Labels: 1) N. Vietnam, Tamdao , 15–23.IX.1997, A. V. Napolov; 2) Zool. Inst. St.Petersburg; 3) Holotype Clavicornaltica tamdao sp. nov. des. A. Konstantinov and C. Duckett ( ZMAS); Paratypes with the same label as holotype (6 ZMAS, 7 USNM).

Diagnosis. Clavicornaltica tamdao has a unique, extremely short duct of the spermatheca ( Fig. 19 ). For other characters see the key below.

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