Diagnosis

Beetle small, reddish-brown to brown, with paler head and pronotal sides, shiny; pronotum without lateral bead; male antennomeres 3–10 stout; protarsomere 4 with middle-sized, slender, evidently curved anterolateral hook; median lobe slender, with very weak submedian constriction in ventral view; paramere with notch on dorsal side and subdistal part short and small, with not numerous, relatively short, thick, flattened, slightly curved at apex setae.

Description

Size and shape: Beetle small (TL-H 3.15–3.5 mm, TL 3.5–3.9 mm, MW 1.65–1.85 mm), with oblong-oval habitus, broadest at elytral middle. Coloration: Head reddish to dark brown, usually paler anteriorly; pronotum dark brown, with reddish sides; elytra uniformly dark brown, except narrow reddish sutural bands; head appendages yellowish-red, legs darker, especially metathoracic legs (Fig. 43).
Surface sculpture: Punctation and microreticulation as in Exocelina irianensis sp. n.
Structures: Pronotum without lateral bead, in a very few specimens with indistinct traces of bead. Base of prosternum and neck of prosternal process with distinct ridge, without anterolateral extensions. Blade of prosternal process lanceolate, relatively broad, slightly convex, with distinct bead and few setae; neck and blade of prosternal process evenly jointed. Abdominal sternite 7 broadly rounded apically.
Male: Antennomeres 3–10 stout (Fig. 17A). Protarsomere 4 with middle-sized, slender, evidently curved anterolateral hook. Protarsomere 5 ventrally with anterior row of 14 short setae and posterior row of 5 short setae (Fig. 17B). Abdominal sternite 7 with 3–8 lateral striae on each side. Median lobe slender, with very weak submedian constriction in ventral view (Fig. 17C). Paramere with notch on dorsal side and subdistal part short and small, with not numerous, relatively short, thick, flattened, slightly curved at apex setae (Fig. 17E).
Female: Antennae more slender, abdominal sternite 7 without striae.

Distribution

Indonesia: Papua Province: Nabire and Paniai Regencies. This species is known only from the type locality area (Fig. 50).

Etymology

Derived from the name of the range, Weyland, at the northern edge of which the type locality is situated. The species name is an adjective in the nominative singular.
