Eniclases similis Bocak & Bocakova, 1991: 210.

Material examined.

10 males, 2 females (BM0003-4, 11, 13-14, 19-24, 37), Indonesia, Irian Jaya, Sentani, Cyclops Mts., 300 m, Nov.-Dec. 1991 (LMBC).

Diagnosis.

Eniclases similis differs from the similarly colored individuals of Eniclases divaricatus in large eyes (Table 1) and from Eniclases bicolor in the gradual transition between the dark and bright parts of elytra (Figs 10, 13-14). Despite distant relationships between Eniclases similis and Eniclases bicolor (Fig. 1) there is no clearly defined morphological character available for their identification.

Redescription.

Male. Body length 7.5-9.7 mm, pronotum, humeral part of elytra, and legs yellow to orange, metathorax, abdomen, apical part of elytra, and sometimes antennae dark brown to black (Figs 13-14). Head with moderately large eyes, their diameter 1.17-1.28 times longer than interocular distance, antennae slender, acutely serrate, with apical process of antennomere 3 about third of antennomere stem. Pronotum transverse, with weak lateral bulge in posterior third, elytra with weak, but straight secondary costae and regular, subquadrate cells.

Distribution.

New Guinea Highlands.

Remark.

Eniclases similis has two extreme forms in the extent of the bright part of elytra (Figs 13, 14) and transitional forms between these. The similar color patterns are present in sympatrically occurring species of Trichalus . The species is identified as Eniclases similis due to the absence of any morphological difference when compared to the holotype of Eniclases similis . The type locality of Eniclases similis is Karimui in Eastern New Guinea and identity of the species needs further investigation.
