12. Sundaoodes kalimantanensis sp. n.

( Figs 15 A–K, Table 3)

Type material. Holotype ♂, in teneral condition, ‘Borneo Exped. [w, h] // Dr. Hallier Mt. Liang Gagang Mrt. [=March] 94. [w, h]’ ( RMNH) . Paratype ♀, mature specimen, with label, ‘ Dr. J. Buttikofr [=Biittikofer] Smitau [Semitau] Jan. 1894 [w, h/p]’ ( RMNH) .

TME: 2 specimens. TGE: 1♂, 1♀.

Diagnosis. This species is easily separated from the previous species by its diamond-shaped and pointed prosternal process apex, distinctly punctured pro- and metepisternum, and significantly greater PW/PA, EL/EW and EL/PL ( Figs 15E, F , Table 3).

Description. Habitus. Moderately large specimens (BL: 11.2–11.3 mm, BW: 4.5–4.8 mm), with elongate, slightly convex body ( Figs 15A, B ). Ratios and measurements. See Table 3. Color and luster. Body black dorsally and ventrally; antennae, palpi, tibiae and tarsi rufopiceous. Integument dorsally and ventrally shiny, without iridescence. Punctuation. Dorsal surface without punctuation except posterolateral parts of pronotum, which sometimes have large and shallow punctures extending laterally to pronotal posterior half; sides of prosternum, pro- and mesoepisternum, abdominal ventrites (1 at base, 2–5 at sides and 6 at apex) with dense and moderately large punctures, sides of metasternum and metepistenum with dense and coarse punctures. Head. Less than half as wide as pronotum (PW/HW: 2.10–2.19). Mentum tooth with apex rounded and paramedial border fine ( Fig. 15D ).

Thorax. Pronotum ( Fig. 15C ) with sides weakly rounded toward posterior angles (PW/PB: 1.03–1.04); maximum width close to posterior angles; laterobasal impressions very faint. Prosternum with indistinct median longitudinal sulcus; prosternal process rhomboidal, slightly pointed, bordered at apex and subapically, bordering decreased or obliterated at sides ( Fig. 15E ). Metepisternum longer than wide, irregularly and coarsely punctate (MA/MM: 0.80– 0.83, Table 3, Fig. 15F ), coadunation with epipleuron short, located anteriorly. Elytra. Apical sinuation moderate, well-defined. Basal margin distinct laterally, forming a minute denticle at shoulder, disappearing medially at level of stria 3. Parascutellar striola and striae in anterior two-thirds of elytron punctate. Intervals 1–7 rather flat, interval 8 slightly convex. Legs. Protarsomeres 1–3 of male moderately dilated, with second tarsomere slightly wider than long (W/Lp2: 1.18). Male genitalia. Median lobe ( Figs 15G, H ) with angle between basal bulb and shaft nearly right; shaft swollen distally; apex straight; apical lamella similar to that of S. hainanensis but narrower and slightly longer. Female genitalia. Basal gonocoxite with one medioapical and three lateroapical setae. Apical gonocoxite with dorsomedial ensiform seta located near middle and two large dorsolateral ensiform setae ( Fig. 15I ). Seminal canal twisted apically; spermathecal gland with atrium ( Figs 15J, K ).

Etymology. The species is named for the toponym “ Kalimantan ”, which is the Indonesian portion of the island of Borneo.

Distribution. Indonesia, West Kalimantan Province (Mount Bukit Liang; Semitau).

Bionomics. Nothing is known about the bionomics of this species. Conjectural GPS coordinates of the type locality suggest that the specimens were found not far from the Kapuas River.

Notes. The type locality, Mount Bukit Liang [Mt. Liang Gagang], is a low mount in the West Kalimantan Province of Indonesia, with GPS coordinates 0°13' (0.2167°) north, 111° 51' (111.85°) east, and elevation of 613 meters .

The holotype is a teneral specimen, with dark brown color and yellowish appendages. Its genitalia are hardly chitinized, with the basal half of median lobe deformed while the apical half is shapely and with a distinct sclerite in the internal sac. The blackish coloration of the female paratype may be more indicative of fully-mature coloration in both sexes.
