Cho, Hee-Wook, 2022, Two new species of the nominotypical subgenus Gonioctena Chevrolat, 1836, from China and Laos, and a proposed new species-group (Coleoptera: Chrysomelidae: Chrysomelinae), Zootaxa 5150 (1), pp. 111-120 : 116

Gonioctena (Gonioctena) kanfani ( Chen, 1941)

( Figs 9 , 12 )

Phytodecta kanfani Chen, 1941: 191 (original description).

Gonioctena (Gonioctena) kanfani: Gressitt & Kimoto 1963: 358 , 362; Medvedev 1999: 14, 2004: 41; Kippenberg 2010: 433; Yang et al. 2014: 365; Yang et al. 2015: 50.

Type locality. China: Anhui Province, Huangshan .

Material. Syntypes probably in Nanjing University, not examined.

Diagnosis. This species is similar to G. lukasi new species in that the pronotum lacks spots and the elytral punctures are arranged in single almost regular rows. However, G. kanfani can be distinguished by the long thin median lobe (greatly swollen in G. lukasi new species).

Distribution. China: Anhui, Zhejiang ( Fig. 12 ).

Remarks. Chen (1941) described Gonioctena kanfani from Huangshan based on two specimens deposited in Nanking University, which became Nanjing University in 1952. The type material has not been found since that time. No specimen was available for the present study. Therefore, the male genitalia of G. kanfani ( Fig. 9 ) were redrawn from Yang et al. (2014), who examined two specimens from Longwang Mountain about 120 km east of the type locality.
