Diamella kaszabi ( Jedlicka, 1952) Habitus: Fig. 45

Diamella kaszabi Jedlička 1952: 82, fig. (original: Diamella ; type locality: Kosempo (Taiwan); holotype deposited in MTMB); Jedlička 1963: 307, Fig. 40 ( Diamella ).

Type examined.

Holotype of Diamella kaszabi Jedlička, by original designation (MTMB): female, body length = 8.1 mm, board mounted, "Formosa / Sauter"; "Kosempo / 908."; “TYPUS” [red label]; " Diamella / Kaszabi sp. n. / det. ING. JEDLIČKA” [pink label][Fig. 45].

Notes on type.

The original literature clearly indicated that this unique specimen is holotype. The type locality “Kosempo” is old name for “Jiasianpu”, a small hill near township of Jiasian, Kaohsiung County. The locality = 23.07088°N, 120.59386°E, altitude about 380m.

Diagnosis.

This species can be readily distinguished from the other two species of the genus by: (1) dorsal side brownish, elytra without metallic reflection; (2) elytral base strongly narrowed, hind wings reduced; (3) striae with punctures very coarse. Furthermore, the species also differs from Diamella cupreomicans by: vertex less tumid, front angles of pronotum not narrowed; and from Diamella arrowi by: pronotum narrower, elytra with some setae along striae.

Description.

Body length 8.1 mm; dorsal side uniform brown, lateral explanate area of pronotum paler, pronotum and elytra with luster but not metallic; mouthparts and antennae reddish brown, apices of mandibles dark brown; legs yellowish brown; ventral side brownish. Head without microsculpture, with punctures and pubescence; tempora slightly shorter than length of eyes; vertex distinctly tumid, but not forming horn-like hump at posterior supraorbital seta insertion. Pronotum slightly wider than head, widest slightly before middle; ratio PW/PL 1.25; pronotal base strongly lobed; front angles not narrowed, slightly projected forward; lateral margins slightly expanded in middle, slightly rounded but not angulate, strongly sinuate before hind angles; hind angles subrectangular, distinctly projected; disc convex, microsculpture indistinct; lateral explanate areas wide and even; basal foveae slightly deep; disc nearly impunctate, with a few punctures along median line and in basal foveae; disc with a few long setae on basal and lateral areas, lateral explanate area glabrous; lateral margins with long accessory setae equidistant along full length; median line distinct, not reaching to apical and basal margins; disc slightly rugose beside median line. Elytra wider than pronotum, shoulder strongly narrowed, hind wings reduced, nearly as long as elytra; elytral lateral border wide, somewhat reflexed up; striae very deep, coarsely and irregularly punctate, with some setae, especially abundant on 5th to 7th striae; intervals convex, odd intervals with secondary pores, primary pores not distinct among the secondary pores, 3rd and 5th intervals with some larger pores; umbilical series of 9th interval composed of 22 pores; disc without distinct depression; 7th and 8th intervals slightly tumid near apex; elytral lateral margins with dense fine setae; epipleura pubescent. Ventral side. Prosternum with long hairs, proepisterna glabrous; mesosternum nearly glabrous; abdomen hairy. Male genitalia unknown. Female genitalia not studied.
