Cassida expansa Gressitt, 1952 

( Fig. 4View FIGURES 4 – 11. 4)

Cassida (Taiwania) expansa Gressitt, 1952: 492  .

Cassida smaragdocruciata Medvedev & Eroshkina, 1982: 114  , syn. nov.

Type locality. China, Hainan Prov., Qiongshan Co.,? Sanlongcun Village [we are not sure whether the transliteration is correct and the locality is unknown to us].

Original type series. Described only from the holotype ( LMNH).

Type material examined. Holotype, pinned: ‘ Hainan Is. South China. | Sam-Lwong-tsʼuen, Lam- | wan-tung (Loi territory) | in Kiung-shan District | August 5-6, 1935. | F. K. To [w, p, cb] || 605 [w, t, cb] || HO[hw]LOTYPE[p] | CASSIDA  [hw] | EXPANSA [hw] | J.L.Gressitt [r, p + hw by Gressitt, cb] || [vernacular name in Chinese, hw] | Taiwania  [hw] | expansa (Gressitt)  [hw] | det. Li-Zhong Hua [in Chinese, p] 1987 [hw] [w, p + hw by Gressitt, cb] || En-289772 | [Data Matrix barcode] SYS [w. p, cb]’.

Current status. Valid species.

Remarks. The species remained rather enigmatic since its description as the latter was not sufficient to recognize the species. Cassida expansa  belongs to the group of species with elevated X-shaped relief in postscutellar area. It is quite conspicuous by its larger size (6.7 mm) and stout body with broadly explanate margin of elytra. Such features have also C. smaragdocruciata  described from Vietnam and we could not find any differences between these two taxa when compared its paratype (deposited at DBET) with the holotype of C. expansa  . Hereby we synonymize C. smaragdocruciata  with C. expansa  .
