Metallanchista laticollis Shi & Liang sp. n. Habitus: Fig. 44 male genitalia: Figs 75 99

Type material.

Holotype (NHMB): male, body length = 7.8 mm, board mounted, genitalia dissected and deposited in microvial pinned under specimen, "Thailand, 1.-20.iii.1996 / Chumphon prov. / Pha To env. 9°48' 98°47' / K. Majer leg."; "HOLOTYPE ♂/ Metallanchista laticollis / new species / Des. SHI H. L. 2011" [red label][Figs 44, 75, 99].

Diagnosis.

Elytra uniform metallic piceous-green, intervals slightly convex; pronotal width 1.65 times length, lateral margins slightly angulate in middle, front angles with only a few very short setae. This species is similar to Metallanchista perlaeta , but can be distinguished from the latter by pronotal lateral margins angulate in middle and dorsal side with less metallic color.

Description.

Body length 7.8 mm; dorsum piceous, head and pronotum with moderate reflection, pronotum slightly brownish, elytra dark green, with strong metallic reflection; antennae, mouthparts yellowish brown, apices of mandibles darker, apices of terminal labial and maxillary palpomeres yellow; femora dark brown, tibiae and tarsomeres reddish brown; ventrum brown. Head glabrous, without microsculpture or punctures. Pronotum strongly transverse, widest slightly before middle; lateral explanate areas very wide and even, with a few punctures; ratio PW/PL 1.65; pronotal base briefly but distinctly lobed; disc moderately convex, microsculpture indistinct, without punctures or pubescence; front angles with a few very short setae; lateral margins slightly angulate in middle, strongly sinuate before hind angles; hind angles obtuse, sharp, not projected, with a few accessory setae; basal foveae shallow, with a few punctures; median line distinct, short, not reaching to base. Elytra with striae shallow, distinct, finely punctate; intervals slightly convex; microsculpture absent; 3rd interval with two setigerous pores, the basal one placed at basal one-third approximately, adjacent to 3rd stria, the apical one placed at apical one-eighth approximately, adjacent to 2nd stria; 5th interval with one setigerous pore near base. Male genitalia with median lobe of aedeagus tubular, slightly compressed; left lateral margin not curved, right lateral margin gently expanded in dorsal view; apical orifice opened dorsally, margin around apical orifice without long setae; apical lamella placed on right side, flat and elongate, apex rounded, length twice width; apical lamella strongly bent dorsally in lateral view; subapical area finely setose on right side. Internal sac without distinct sclerite; two separate areas near to dorsal margin strongly and coarsely scaled, basal one smaller and more coarsely scaled; main flagellum and trumpet-form expansion reduced to a hardly visible semi-sclerotized sclerite near base ( Fig. 75 ). Female genitalia unknown.

Distribution

( Map 4 ). Only known from the type locality PhaTo (Thailand).

Etymology.

The name " laticollis " is from the Latin " lat- " meaning wide and " coll " meaning neck, referring to the pronotum. This species is named for its rather wide pronotum.
