Dactylispa (Triplispa) paucispina Gressitt, 1939

( Fig. 24 )

Dactylispa paucispina Gressitt, 1939a: 178 .

Type locality. China, Guangdong prov., Lianzhou Co., Yaoshan, approx. 25°51′N, 110°07′E, 840 m a.s.l.

Original type series. Holotype ( LMNH) and one paratype from Jiangxi (coll. Gressitt).

Type material examined. Holotype, glued: ‘Kwangtung, S. China | Yaoshan(Mt. range) | Lin-hsien(District) | April 27–28, 1934 | F. K.

Current status. Valid species in the subgenus Triplispa Weise, 1897 .

Remarks. The species belongs to the D. angulosa Solsky, 1872 group characterized by elytra with tubercles instead of spines. Identification of species within the group is complicated as the variability of individual taxa is not yet fully understood. Dactylispa paucispina has been differentiated from other Chinese species by the third major tubercles on the second and the fourth interval basally fused while these are separated in other species.
