Fig. 3A–D

Cis (Cis) palawanus Chûjô, 1966: 528 (original description).

Comments. From the Province of Palawan, Philippines. This species is known only from the holotype and fits the limits of Nipponocis Nobuchi & Wada, 1955: body elongate, large, parallel-sided; 10-segmented antennae; dual pronotal and elytral punctation; all tibiae with simple outer apical angle; and males with anterocephalic edge with two tubercles and first abdominal ventrite without sex patch (Nobuchi 1955). It differs from other species in the genus, except for Nipponocis ashuensis Nobuchi, 1959, in the emarginate anterior edge of the pronotum. Nipponocis ashuensis differs from Nip. palawanus in the dual dorsal vestiture, consisting of short decumbent and long erect setae. Besides Nip. ashuensis and Nip. palawanus, Nipponocis includes three other described species: Nip. longisetosus Nobuchi, 1955, Nip. magnus Nobuchi, 1955 and Nip. unipunctatus Nakane & Nobuchi, 1956. The genus occurs in the Indo-Malayan transition zone and Chinese transition zone.
