Micropseudochillus subgen. nov.

Type species. Pseudochillus (Micropseudochillus) palawanus sp. nov., here designated.

Description. Body length 3.2–3.9 mm. Clypeus concave with small tooth situated slightly to the right ( Fig. 13 ). Tempora at most as long as eye length. Suborbital keel reduced. Occiput sometimes with mid-longitudinal impression. Intervals on elytra without humeral corner, base of elytra slightly narrower than pronotal base, elytra with one row of setae on intervals 1, 3, 5, 7 and 9. Antennomeres thick, wider than long, only antennomere 3 can be slightly longer than wide. Differential diagnosis. Micropseudochillus subgen. nov. differs from both remaining subgenera in oval elytra without humeral corners; elytra with rows of setae; antennomeres thick and wider than long. The remaining subgenera have elongate elytra, almost parallel in middle third; junction of intervals 7 and 9 forming small obliquely directed humeral corner; glabrous elytra; antennomeres longer than wide.

Etymology. The name refers to Greek ‘ mikros ’ = small and the genus name Pseudochillus ; gender masculine.
