Material examined.

Lectotype. Female, New Guinea, Humboldt Bay, Doherty lgt., coll. Pic (MHNP). Other material examined. 4 males, 2 females (BM0001-2, 9, 15-17), Indonesia, Irian Jaya, Sentani, Cyclops Mts., 300 m, Nov.-Dec. 1991; female (BM0057), Indonesia, Irian Jaya, Elelim, path to Apalapsili, 600 m, Nov.-Dec. 1991 (LMBC).

Diagnosis.

Eniclases divaricatus is the only Papuan species with the bicolored elytra and flabellate male antennae (Figs 6, 34). Additionally, this species has the characteristic pattern of bright humeri and dark colored suture, which is shared only with some specimens of Eniclases similis from the same locality (Figs 6, 13). The similarly colored females cannot be distinguished as their relative size of eyes is similar (Table 1).

Redescription.

Male. Body length 8.8-9.7 mm. Head, thorax, legs, and humeri yellow to orange, antennae except basal part, abdomen, and most of elytra dark colored. Head with moderately large, hemispherically prominent eyes, their diameter 0.92-0.96 times minimum interocular distance Antennae flabellate, lamella of anten nomere 3 slightly longer than the body of antennomere, other lamellae similar (Fig. 34). Pronotum transverse, with almost straight, slightly elevated lateral margins, elytra with quite strong straight secondary costae and regular dense cells (Fig. 6).

Distribution.

Central North New Guinea.
