Glyphocassis tetrasticta Gressitt, 1942

( Fig. 10 )

Glyphocassis tetrasticta Gressitt, 1942: 3, 1952: 478 (synonymy).

Type locality. China, Sichuan, Ya’an Pref., Lingnan.

Original type speries. Described only from the holotype ( WCUU).

Type material examined. Holotype, pinned: ‘SIKONG | Lingnan | 27.VIII. [hw]1939[p] | D. S. Pen [w, p, cb] || HOLOTYPE | GLYPHOCASSIS [hw] | TETRASTICTA [hw] | J.L.Gressitt [r, p + hw by Gressitt, cb] || Glyphocassis [hw] | lepida [hw] | Sp [hw] | J.L.Gressitt Det.19 [w, p + hw by Gressitt, cb] || En-289742 | [Data Matrix barcode] SYS [w. p, cb]’.

Current status. Synonym of Glyphocassis lepida (Spaeth, 1914) .

Remarks. Gressitt (1942) stated that the holotype was collected on ‘ July 24, 1939 ’ while the specimen above bears date 27th August 1939 and stated WCUU as depository. As the specimen possesses the original Gressittʼs labels, agrees with the figure provided in the original description, and we do not know about existence of any other specimen we consider it as the holotype. Gressitt probably described this species because G. lepida was at that time placed in the genus Hebdomecosta Spaeth, 1915 and he was not aware of it. Gressitt (1952) synonymized the species with G. lepida without any additional note. We have studied types of both taxa and the synonymy is correct. Sikong refers to Ya’an prefecture level city in Sichuan, however, we were unable to find any place named Lingnan.
