Material examined.

Holotype. Male (BM0054), Indonesia, Irian Jaya, Elelim, path to Apalapsili, 600 m, Nov.-Dec. 1991 (LMBC). Paratypes. 1 male, 3 females (BM0048-49, 53, 55), same data as the holotype; 7 males, 8 females (BM0025-32, 34-36, 86, 88, 90-91), Indonesia, Irian Jaya, Bokondini, 1300 m, Nov.-Dec. 1991; 4 males, female (BM0063-67), Indonesia, Irian Jaya, Dombomi, Lower Pass valley, 1200 m; 2 males (BM0008, 12), Indonesia, Irian Jaya, Sentani, Cyclops Mts., 300 m, Nov.-Dec. 1991 (LMBC).

Diagnosis.

Eniclases variabilis is a widespread, highly polymorphic species and resembles in general appearance several distinct, sympatric mimetic types. The color forms are illustrated in Figs 20-29. Similarly colored individuals of Eniclases niger differ in the large eyes (1.17-1.28 times larger than eye distance) and acutely serrate antennae of Eniclases variabilis (Figs 38, 40). The similarly colored individuals of Eniclases elelimensis can only be identified using the DNA data.

Description.

Male. Body length 6.6-8.2 mm. Head, antennae, thorax, and abdomen dark black, elytra orange yellow in humeral third, rest of elytra black, transitional zone between bright and dark part of elytra is narrow (Figs 20-29, 38), trochanters brown, rest of legs black. Head with small, hemispherically prominent eyes, their diameter 0.83-0.95 interocular distance, antennae flat, slender, acutely serrate, apical process of antennomere 3 about half length of its body, further antennomeres similar in shape. Pronotum transverse, with weak bulge in basal third, elytra with weak secondary costae and mostly regular, subquadrate cells (Fig. 20).

Distribution.

Central North New Guinea.

Etymology.

The specific name refers to exceptional variability in coloration.

Remark.

Eniclases variabilis can be differently colored in various localities. Generally, the dark colored specimens (Fig. 27) were found in higher elevations in Bokondini (1300 m) and Dombomi (1200 m) and bright colored individuals (Figs 22-23, 26) were collected in lower elevations in Elelim (600 m) and Cyclops Mts. (300 m) (Fig. 3).
