Kojima, Hiroaki, Ayri, Shaloo & Ramamurthy, V. V., 2016, Eusynnada, a resurrected genus of Ochyromerina (Coleoptera: Curculionidae: Curculioninae: Tychiini), with description of a second species from India and Thailand, Zootaxa 4066 (4), pp. 469-476 : 474-475

Eusynnada canariumi sp. nov.

( Figs. 3, 4 , 7, 8 , 13 , 24–30 )

Description. Male. Length: 4.4–4.8 mm; width: 1.9–2.0 mm.

Male. Very similar to E. plaxioides except derm concolorous reddish brown except antennae and tarsi slightly paler; rostrum slightly shorter than pronotum (9: 10); antennae inserted at middle in female; prothorax 1.3 times as wide as long; elytra 1.6 times as long as wide; front tibiae slightly dentate ventrally near apex; aedeagal body truncate at caudal margin, apodemes short, about 1/3 of aedeagal body.

Female. Resembles male except rostrum longer than pronotum (13–15: 10); antennae inserted at middle of rostrum.

Type series. Holotype: male, Doi Suthep-Doi Pui, Thailand, 4–7.vii.1995, H. Kojima (TUA). Paratypes, 3 males and 2 females, same data as the holotype; 1 male and 5 females, Port Blair, S. Andaman, India, 16.xii.1991, Venna ( NPC) [teneral].

Etymology. This species is named after the plant genus Canarium on which weevils were collected.

Biology. Weevils were collected from Canarium euphyllum Kurz. (Burseraceae) on Andaman Island. Weevils were also captured on a flowering tree probably belonging to Neolamarckia sp. ( Rubiaceae ) in Thailand by using an insect net with a long handle, which is about 6 m in length.

Distribution. Andaman Island ( India), Thailand.

Comment. This new species is easily separable from the type species by the coloration.
