Holoarcus intermedius (C. Willemse, 1932)

Figs 10, 11

MATERIAL. Indonesia: Southwest Papua province, Raja Ampat Archipelago, Batanta Island , 3 January 2020, 1 ♂, 1 ♀, leg. M. Mironov.

MEASUREMENTS. Length body: ♀ 13.7, ♂ 13.2; pronotum: ♀ 16.1, ♂ 15.0; fore femur: ♀ 3.5, ♂ 3.0; mid femur: ♀ 4.0 ♂ 3.5; hind femur: ♀ 10.7, ♂ 9.5; ovipositor 2.0 mm.

DISTRIBUTION. Indonesia: Southwest Papua province. This species was known only from New Guinea Island. Here H. intermedius is recorded from Batanta Island for the first time.

REMARK. This species is easy to identify, in lateral view, by the concave emargination at the posterior end of the pronotum. Record of H. intermedius from Maluku province of Indonesia ( Tumbrinck, 2014) needs confirmation because specimens from Walir Island characterized by more flattened in the middle pronotum.

I thank A. V. Gorochov (St. Petersburg, Russia) for the opportunity to study the collections of the Zoological Institute. The research was carried out within the state assignment of Ministry of Science and Higher Education of the Russian Federation (theme No. 124012400285-7).
