Material examined.

Holotype (MZB): ARC0500 (EMBL # FN429207), WEST NEW GUINEA, Jayapura Reg., Cyclops Mts, Sentani, S02°32.2', E140°30.4', 545-700 m, 02-XII-2007, beaten. Paratypes (SMNK, ZSM): WEST NEW GUINEA, Jayapura Reg., Cyclops Mts, Sentani: 1 ex, ARC0501 (EMBL # FN429208), same data as holotype; 1 ex, ARC0503 (EMBL # FN429210), S02°32.0', E140°30.4', 700-900 m, 02-XII-2007, beaten.

Distribution.

Jayapura Reg. (Cyclops Mts). Elevation: 700 m.

Biology.

Collected by beating foliage.

Etymology.

This epithet is based on a combination of the name of Trigonopterus politus (Faust) and the Greek suffix eides (similar) and refers to their superficial similarity.
