Basiprionota octomaculata ( Boheman, 1850) View in CoL

Prioptera 8-maculata Boheman, 1850: 56 (original description).

Prioptera gibbosa Baly, 1863: 9 (original description), syn. nov.

Type localities. Prioptera gibbosa : ‘ Tringanee’ [= Malaysia, Terengganu]; P. 8-maculata: ‘Java’.

Type material examined. Prioptera gibbosa : HOLOTYPE: ♀, pinned, ‘Ting [w, hw by Baly, cb] || Type [w, p, s, c, rf] || Tringano [hw] | Baly Coll. | 1905—54. [w, p, cb] || Prioptera | gibbosa | Baly | Malay Penninsula [g, hw by Baly, cb] || Coll | Castelnau | Stevens | Type [hw by Baly on underside of preceding label]’ ( BMNH).

Prioptera 8-maculata: LECTOTYPE (designated by BOROWIEC 1999a): ♀, pinned, ‘ Java [w, p, s] || Mhm. [w, p, cb] || Type. [w, p, s] || LECTOTYPE | des. L. Borowiec [r, p, cb] || NHRS-SRAH | 000000084 [w, p, cb]’ ( NHRS).

Remarks. BALY (1863) did not state how many specimens he had at his disposal. However, he most likely had only a singleton based on the description of its colouration and it is here considered as holotype. Baly did not provide any comparative diagnosis to other species, but simply stated in the foreword of the publication that he acquired the material too late to include it in the supplement to Monographia Cassididarum ( BOHEMAN 1862). Baly purchased this specimen on Stevenʼs auctions and it originally came from material of Laporte de Castelnau.

Basiprionota gibbosa is very characteristic due to its strongly convex elytra with postscutellar tubercle and yellow antennae and the only similar species is B. octomaculata Boheman, 1850 . BALY (1863) described B. gibbosa from a female specimen that perfectly matches the lectotype of B. octomaculata . Basiprionota gibbosa is thus considered a junior subjective synonym of the latter species.

The type locality of B. gibbosa , ‘Tringanee’, refers either to the State of Terengganu or city Kuala Terengganu situated in the mouth of the Terengganu River in Malaysia.

Distribution. Indonesia: Java ( BOHEMAN 1850), Sumatra ( SPAETH 1925, BOROWIEC 2009a); Malaysia: Terengganu ( BALY 1863).
