Ptomaphaginus agostii spec. nov.

( figs 1-2 ).

Type material.— Holotype ♂: Indonesia: Java: W Java: Cibodas , 50 km E of Bogor, 1400 m alt., 3-6.xi.1989 ( MHNG) . Paratypes: 1 ♂, 5 ♀♀ with the same collection data ( MHNG; CMPR) .

Diagnosis.— Habitus ovoid. Male with a large, flat, central sternal plate extended from the anterior margin of the 3 rd visible sternite to the apical edge of the 6 th and regularly widened from the front to the apex.

Description.— Habitus ovoid. Colouration dark brown on the head, pronotum, and elytra, red brown on the legs, and yellow on the antennae, with articles 5 to 8 darker. Length: 2.3-2.9 mm (n = 7). Antennae 1.1 times longer than the width of the head. Male protarsi 0.75 times as wide as the protibia. Pronotum 1.7 times as wide as long, the caudal corners slightly drawn out. Elytra 1.3 times as long (measured from the caudal tip of the scutellum) as their combined width, truncated in both sexes. Male with a large central sternal flat plate extended from the anterior margin of the third visible sternite to the apical edge of the 6 th and regularly widened from the front to the apex. Aedeagus ( figs 1-2 ) more slender than P. giachinoi , slightly narrowed in the basal half, parallel in the third quarter, then triangularly narrowed at the apex, with two lateral acuminated flaps, just before the apex.

Distribution.— Known only from the type locality, Cibodas in West Java.

Remarks.— Probably related to P. giachinoi and P. loeblianus because of the presence of two setae on each of the lateral flaps of the aedeagal apex..

Etymology.— Dedicated to D. Agosti, one of the collectors of this species.

Ptomaphaginus sinuatus Schilthuizen, 1984

Material.— Indonesia: Java: W Java, Mt. Gede , 50 km SE Bogor , 2000-2200 m, 5.xi.1989, leg. Agosti, Löbl, Burckhardt: 2 ♂♂, 3 ♀♀ ( MHNG, CMPR).

Remarks.— This species was only known from the holotype from Cigembong, SW Java, at 600 m altitude ( Schilthuizen, 1984). These new specimens (which morphologically correspond closely with the holotype, with the exception that the habitus and aedeagus are somewhat less slender) derive from a locality in the vicinity, but at much greater altitude.
