Eusynnada plaxoides Heller, 1925: 226 (Sumatra) View in CoL ; Voss, 1937: 136 (Java).

Redescription. Male. Length: 5.3 mm; width: 2.4 mm.

Derm reddish to light reddish brown, antennae and tarsi yellowish brown, elytra black except apical, lateral and faintly basal margins.

Head with fine, separate punctures; front of head between eyes 3/5 as wide as base of rostrum. Rostrum shorter than pronotum (4: 5), slightly arcuate in lateral view; dorsum subconfluently punctate and sulcate behind position of antennal insertion, which is at apical third of rostrum. Antennae with scape nearly as long as funicle and with first segment of club combined; funicle with first segment about 1.5 times as long as broad, second 3/5 times as long as first, third to fifth subequal in length, nearly half as long as second, sixth and seventh subequal in length, slightly longer than fifth; club nearly as long as basal five segments of funicle combined.

Prothorax 1.4 times as wide as long, widest before middle; dorsum finely punctate, each puncture with fine recumbent pale seta, interstices between punctures about as wide as diameter. Scutellum hardly punctate, thinly clothed with fine recumbent pale setae. Elytra 1.5 times as long as wide, widest at middle; intervals flat, much wider than striae, each with 1–2 irregular rows of small punctures, each of which bears fine recumbent pale seta; striae punctate, punctures larger than those of intervals, septa between punctures almost of same height as intervals. Legs clothed with fine recumbent setae; front tibiae dilated internally on apical fourth, each distinctly dentate ventrally near apex, with inner setose fringe along anterior margin.

Underside clothed with fine recumbent setae. Prosternum with distance between coxae and submarginal sulcus greater than that between this sulcus and anterior margin. Mesosternal process about 1/3 as wide as coxa. Venter with first ventrite slightly depressed in middle.

Terminalia as illustrated ( Figs. 18–20 View FIGURES 18 – 23 ); aedeagal body tapered and rounded at caudal margin, apodeme slightly less than half the length of body.

Female. Length: 5.6 mm; width: 2.5 mm.

Resembles male except rostrum longer than pronotum (13: 10), dorsum punctate, but not sulcate behind position of antennal insertion, which is slightly behind middle of rostrum; antennae with first segment of funicle about twice as long as broad; front tibiae slightly dentate ventrally near apex and venter with first ventrite flattened in middle.

Specimens examined. Male holotype and female paratype, (Museum für Tierkunde, Dresden), labeled “Bandar Baroe, 850 M, Sumatra’s O. K., 12. 9. 21, J. B. Corporaal”.
