Ptomaphaginus loeblianus spec. nov.

( figs 3-4 )

Type material.— Holotype ♂: Indonesia: Sumatra: W Sumatra, Padangpanjan , 600 m alt., 17.xi.1989, leg. Agosti, Löbl, Burckhardt ( MHNG).

Diagnosis.— Habitus ovoid. Species well characterized by the complex apical structure of the aedeagus ( figs 3-4 ).

Description.— Habitus ovoid. Light brown, the legs and antennae lighter, nearly yellowish. Length: 2.6 mm. Antennae 1.1 times as long as the width of the head. Male protarsi dilated, 0.7 times as wide as the apex of protibia. Pronotum 1.8 times wider than long, nearly as wide as elytra, the apical corners drawn out. Elytra 1.25 times longer than their combined width. Aedeagus ( figs 3-4 ) elongated with a central apical expansion, surrounded by two lateral ones both with a perpendicular external tooth and folded towards the down side at the apex, where it carries several ventrally-oriented setae, as in P. giachinoi , with which it appears closely related (as the latter, it and P. agostii also carry two setae on the dorsal side of each aedeagal flap). Internal stylus long and thin.

Distribution.— Presently known only from the type locality: Padangpanjan in Western Sumatra.

Etymology.— dedicated to one of the first collectors of this species: Ivan Löbl.
