Cassida juglans Gressitt, 1942 

( Fig. 6View FIGURES 4 – 11. 4)

Cassida juglans Gressitt, 1942: 4  .

Type locality. China, Zhejiang prov., Deqing Co., Moganshan, approx. 30.60°N, 119.89°E.

Original type series. Holotype (Museé Heude, Shanghai) and one paratype with unspecified depository.

Type material examined. Holotype, glued: ‘ 6. I. 36 [hw] | O. PIEL, coll. [w, p, cb] || Mokan Shan | Musée Heude [w, p, cb] || M-1046 [w, hw, cb] || HOLOTYPE | CASSIDA  [hw] | JUGLANS [hw] | J.L.Gressitt [r, p + hw by Gressitt, cb] || CASSIDA  | ( TAIWANIA  ) | JUGLANS | GRESS. | J.L.G. Det. 1950 [w, hw by Gressitt, cb] || En- 289743 | [Data Matrix barcode] SYS [w. p, cb]’.

Current status. New synonym of Cassida concha Solsky, 1872  .

Remarks. Cassida juglans  remained since its description rather enigmatic as Gressitt (1942) compared it to C. nigriventris Boheman, 1854  , probably mainly because of combination of uniformly pale yellow dorsum and black ventral side, and later transferred the species to subgenus Taiwana Spaeth, 1913 ( Gressitt 1952). Chen et al. (1986) probably merely followed the original description as they retained C. juglans in Taiwana  while the holotype lacks features typical for Taiwania  such as transparent explanate margin with honeycomb structure. The holotype of C. juglans  is conspecific with C. concha  and is synonymized with it here.

The species was recorded only once since is description from Korea ( An et al. 1985). Cho & Borowiec (2014) noted that the record most likely belong to a different species, however, they were not able to locate the original voucher specimen(s).

Gressitt (1942) stated that the holotype was collected on ‘ May 6, 1936 ’ while the specimen bears date 6th January 1936 what is probably result of an error as all other characters and data are in accordance with the primary description.
