Agosti [F91036, leaf litter] (MHNG). <b>Distribution.</b> Papua New Guinea; Indonesia: Papua, West Papua, Moluccas. <b>Comments.</b> This species was based on two specimens from Sattelberg, on the Huon Peninsula, Morobe Province. It differs drastically from its congeners by the parameres split to form two long lobes. The aedeagus illustrated in LÖBL (1975) has the internal sac extruded and the figures given in that paper lack detail. Therefore, new illustrations (Figs 11 -13) are given here. The followings characters are newly given: elytra with basal striae entire, joined to lateral striae; lateral striae fairly coarsely punctate; male protarsomere I about as wide as half of protibial apex, somewhat longer than protarsomeres II and III combined; protarsomeres III slightly lobed, with long apicoventral setae not widened. Gonocoxite as Fig. 14, without gonostyle. The specimens from the island Wokan are only 1.88 1.97 mm long, smaller than specimens from New Guinea, and have the median part of the metaventrite deeper impressed and more coarsely punctate. The shape of the narrow basal sclerite of the internal sac varies from circular to oval.
