Eniclases niger sp. n. Figs 15, 16, 40, 49

Material examined.

Holotype. Male (BM0059), Indonesia, Irian Jaya, Elelim, path to Apalapsili, 600 m (LMBC). Paratypes. 3 males (BM0058, 60-61), same data as the holotype; 2 males, 1 female (BM0033, 87, 89), Indonesia, Irian Jaya, Bokondini, 1300 m, Nov.-Dec. 1991 (LMBC).

Diagnosis.

Eniclases niger is polymorphic in coloration and can be uniformly black or can have the brightly colored pronotum and scutellum (Figs 15-16). The latter specimens resemble some individuals of Eniclases variabilis sp. n. when they occur in the same locality. These two species differ in the relative size of eyes (Table 1).

Description.

Male. Body length 9.2-11.6 mm (Table 1), uniformly dark colored, only trochanters and bases of femora brown (Fig. 16). Head with large hemispherically prominent eyes, their diameter 1.17-1.28 times distance between eyes. Antennae serrate, with apical process about a third of antennomere stem (Fig. 40). Pronotum transverse, with almost straight lateral margins, lateral bulge inconspicuous, elytra with weak secondary costae and in some parts with irregular cells.

Distribution.

New Guinea, Central Mountains.

Etymology.

The specific name refers to body coloration.

Remark.

Eniclases niger has two forms (Figs 15, 16). The specimens from Bokondini have the brightly colored pronotum and scutellum (Fig. 16), the individuals from other localities are uniformly dark colored (Fig. 15).
