Type material examined

( Taiwan: 3). Holotype. Taiwan • Kosempo , H. Sauter, 1909, bears a red label reading “ Type ”, SNSD, JHL_ACITAI_001 .

Non-type material.

Taiwan • “ 16. VII. 20 ”, T. Kano (1, NMNS), JHL_AREV_591 ; • 20. VI. 1938, unknown collector (1, TUA), JHL_AREV_592 .

Diagnosis.

Body length 5.0–7.0 mm. Easily distinguished from other East Asian Acicnemis by the (1) large size (2) black to dark red cuticle largely naked, but with bright yellow scaled bands running longitudinally across the lateral edges of the pronotum and elytral humeri, as well as transversally across the apical 1 / 2 of the elytra.

Distribution.

This species is known only from Taiwan.

Remarks.

Many similarly patterned, large species that presumably form a distinct clade within Acicnemis are present throughout Southeast Asia (e. g., A. ibis Faust, 1896 and A. peduncularis Pascoe, 1872 ), and a number of these remain undescribed.
