Name

Exocelina wondiwoiensis Shaverdo, Hendrich & Balke sp. n.Wikispecies linkZooBank linkPensoft Profile

Type locality

Indonesia: West Papua Province: Teluk Wondama Regency, Wandammen Peninsula, Wondiwoi Mts., Wasior, 2°45.94'S, 134°31.74'E.

Type material

Holotype: male “Indonesia: West Papua: Wandammen, Wasior, 4-5.I.2001, leg. A. Riedel 2?[°]45.940'S 134?[°]31.738'E” (ZSM). Paratypes: 11 males, 20 females with same label as the holotype, 2 males with additional green labels “56 DNA M Balke”, “57 DNA M Balke” (NHMW, ZSM). 4 males, 6 females “IRIAN JAYA: Kabup. Nabire Wandammen penins. Wondiwoi-Mts., 29.-30.7.1998 6h from Yeretua, 560 m leg. M. Balke (WA 9)” (NHMW). 8 males, 9 females “IRIAN JAYA: Wandammen Bay, Wondiwoi Mts. Wasior, 250-600 m, 4.I.2001 leg. A. RIEDEL” (SMNS, ZSM, NHMW).

Diagnosis

Beetle small, externally very similar to Exocelina irianensis sp. n. but darker: dark brown to piceous, with head (in some specimens only its anterior part) paler; shiny; pronotum without lateral bead; male antennomeres 3–5 distinctly enlarged; male protarsomere 4 with large, thick, evidently curved anterolateral hook; median lobe with very strong submedian constriction, distal and proximal parts equally broad, and asymmetrical apex in ventral view; paramere with shallow notch on dorsal side and subdistal part short and small, with not numerous, relatively short, thick, and flattened setae. The species is very similar to the previous one and differs from it only by the assymetrical shape of the apex of the median lobe.

Description

Size and shape: Beetle small (TL-H 3.45–3.8 mm, TL 3.8–4.25 mm, MW 1.8–2.05 mm), with oblong-oval habitus, broadest at elytral middle. Coloration: Head reddish to piceous, with reddish anterior part; pronotum reddish to piceous, with reddish sides; elytra uniformly dark brown to piceous, in paler specimens with narrow reddish-brown sutural bands; head appendages yellowish-red, legs darker, metathoracic legs to dark brown (Fig. 39).
Surface sculpture: Dorsal punctation as in Exocelina irianensis sp. n. but slightly coarser, especially on head. Head, pronotum, and elytra with weakly impressed microreticulation, dorsal surface, thus, shiny. Head with microreticulation stronger. Metaventrite and metacoxa distinctly microreticulate, metacoxal plates with longitudinal strioles and transverse wrinkles. Abdominal sternites with distinct microreticulation, strioles, and fine sparse punctation, coarser and denser on two last abdominal sternites.
Structures: Pronotum without lateral bead, in some specimens with indistinct traces of lateral 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 truncate apically.
Male: Antennomeres 3 and 4 strongly enlarged, evidently larger than other, antennomere 5 distinctly enlarged, 6–9 robust (Fig. 13A); antennomeres 3–6 strongly and 7–9 somewhat rugose ventrally. Protarsomere 4 with large, thick, evidently curved anterolateral hook. Protarsomere 5 ventrally with anterior row of 11 short setae and posterior row with 5 short setae (Fig. 13B). Abdominal sternite 7 with 7–8 lateral striae on each side. Median lobe with very strong submedian constriction, distal and proximal parts equally broad, and asymmetrical apex in ventral view (Fig. 13C). Paramere with shallow notch on dorsal side and subdistal part short and small, with not numerous, relatively short, thick, and flattened setae (Fig. 13E).
Female: Antenna simple; traces of bead on pronotal sides are more often observed than in males; abdominal sternite 7 without striae.

Distribution

Indonesia: West Papua Province: Teluk Wondama Regency. This species is known from the Wondiwoi Mountains of Wandammen Peninsula (Fig. 50).

Etymology

The species is named for the type area, Wondiwoi Mountains. The name is an adjective in the nominative singular. Key to species of the Exocelina ekari-group The key is based mostly on the male characters. In many cases females cannot be assigned to species due to similarity of their external and internal structures (for female genitalia see Figs 17a and 17b in Shaverdo et al. (2005)[1]. Some species are rather similar in point of external morphology, therefore, in most cases the male genitalia need to be studied for reliable species identification. Numbers in brackets refer to an arrangement of the species descriptions above.
