Anisoderomorpha malayana Toki , sp. nov.

( Figs. 42–57 )

Material examined. Holotype: male ( MCSN), “ MALAYSIA, Cherating , 24.I–1.II.1998, leg. Ing. D. Farbiak / Museo Civico di Genova. ”

Diagnosis. This species can be easily separated from all other Anisoderomorpha species by the following characteristics: scutellar shield transverse; elytra blue with metallic luster; apex of elytra truncate and produced at the outer angle; protibia dilated apically.

Description. Male. Body length = 11.27 mm. Elytral length = 7.05 mm.

Coloration dark red; elytra blue with metallic luster; apices of mandibles, antennae except base, scutellar shield except middle, femora except base, tibiae, and tarsi black.

Head ( Fig. 44 ) almost symmetrical. Clypeus triangular, asymmetrical. Antenna ( Fig. 45 ) with 5-segmented club; antennomere III> II = IV = V = VI; VII dilated terminally, as long as wide; VIII dilated terminally, strongly transverse, distinctly wider than VII, narrower than IX and X, as wide as XI; IX and X strongly transverse; XI rotundate-ovate.

Pronotum ( Fig. 46 ) oblong, longer than wide, the widest at middle of lateral sides; lateral side slightly sinuate just before posterior angles; basal margin only distinctly arched posteriorly at median part; anterior angles rounded; posterior angles projected, pointed. Prosternal process ( Fig. 47 ) short, subparallel-sided, truncate. Metaventrite acutely notched between the hind coxae, with a shallow groove along the midline.

Scutellar shield ( Fig. 48 ) transverse; apex acute. Elytra ( Figs. 48–50 ) narrowed apically at posterior part; the intervals minutely punctured; apices slightly divergent at suture, truncate, produced at the outer angle. Protibia ( Fig. 51 ) smooth, dilated apically and outwardly. Mesotibia smooth. Metatibia smooth. Tarsi moderately dilated and fairly long. Abdominal ventrites 1–3 with a deep pit on each side.

Male terminalia. Sternite VIII ( Fig. 53 ) parallel-sided, arched posteriorly; posterior part closely pubescent and punctate. Tegmen ( Fig. 54 ) ventrally with a pair of sclerotized ridges in middle, enclosing penis; parameres symmetrical in length, flattened, stout, with long setae at apical part. Penis ( Figs. 55, 56 ) long, flat, strongly curved laterally; narrowed apically, rounded at the apex; penile struts slightly longer than median lobe excluding penile struts.

Female. Unknown.

Etymology. The new species is named after the type locality, Malaysia.

Distribution. Malaysia (Cherating).
