Pronotum and elytra with weakly impressed microreticulation, dorsal surface shiny. Head with microreticulation stronger.

sp. n. is described using the material from three different regions (Fig. 53). The specimens from these regions demonstrate variability in size (from Bewani: TL-H 3.35-3.45 mm, TL 3.7-3.75 mm, MW 1.75-1.8 mm; Nabire-Enarotali: TL-H 3.1-3.4 mm, TL 3.45-3.85 mm, MW 1.65-1.85 mm; Noiadi: TL-H 3.6 mm, TL 4 mm, MW 1.95 mm), dorsal punctation (in specimens from Nabire-Enarotali, it is slightly coarser), shape of the median lobe (in the specimen from Noiadi, the median lobe with weaker submedian constriction in ventral view and upper margin of apex more straight in lateral view (Figs 21D, 22D, 23D), and setation of the paramere (in specimens from Bewani and Papua, subdistal and proximal setae more numerous, with upper subdistal setae very distinct (Figs 21E, 22E, 23E).

<paragraph pageId="2" pageNumber="3">At first, we intended to describe the species with three subspecies as these morphological differences are evident and stable within each region, though insignificant. Finally, we have decided against this, bearing in mind that more material is needed from these regions (especially, from Noiadi) and the regions in-between for a conclusion whether they belong to the different subspecies or maybe even species.</paragraph>
