Callispa fortunii emarginata Gressitt, 1938

( Fig. 3 )

Callispa fortuneii emarginata Gressitt, 1938b: 322 .

Type locality. China, Hainan prov., Qiongzhong Co., Wuzhishan Mt., approx. 18°53.9′N, 109°42.2′E, 750–1840 m a.s.l.

Original type series. Holotype ( USNM) and two paratypes ( LNHM, coll. Gressitt) all from the same locality with different dates of collecting.

Type material examined. Paratype, pinned: ‘Ta Han | Hainan Is | VI-23 -ʼ35 [w. p, cb] || L.Gressitt | Collection [w, p, cb] || PARATYPE | CALLISPA [hw] | FORTUNII [hw] | EMARGINATA [hw] | J.L.Gressitt [y, p + hw by Gressitt, cb] || CALLISPA | FORTUNII | EMARGINATA | GRESS. | J.L.G. Det.1950 [w, hw by Gressitt, cb] || En- 289761 | [Data Matrix barcode] SYS [w. p, cb]’.

Current status. Synonym of C. fortunii Baly, 1859 .

Remarks. This taxon was described on the basis of shorter and stouter body and more deeply emarginate anterior margin of pronotum in comparison to the typical C. fortunii Baly, 1859 . Subsequent authors accepted the validity of the subspecies except of Borowiec & Sekerka (2010) who listed the taxon as synonym of the nominal species. We observed that the width of the pronotum as well as its emargination is subject to intraspecific variability. Seems that the body is gradually slightly stouter and the pronotum slightly more emarginate in southern gradient of the species distribution.

Baly (1859) named this species after the collector of the material Mr. R. Fortune and used the spelling ‘ Fortunii’. Subsequent authors (e.g. Gemminger & Harold 1876, Weise 1911, Gressitt 1938b) used various spellings such as ‘ fortunei ’, ‘ fortuneii ’ or ‘ fortuni ’. All these variations must be considered as unjustified emendations according to articles 32.5.1. and 33 of the Code ( ICZN 1999) or incorrect subsequent spelling in case of ( Hua 2002).

The type locality Ta Han refers to Wuzhishan Mt. (Hua 2015, pers. comm.).
