Cryptocephalus ( s. str. ) parvulus, O. F. Muller, 1776

Duan, Wen-Yuan, Wang, Feng-Yan & Zhou, Hong-Zhang, 2025, Two new species and one new country record for the Cryptocephalus parvulus group (Coleoptera: Chrysomelidae: Cryptocephalinae) from China, Zootaxa 5691 (2), pp. 341-352 : 342

Taxonomy of the Cryptocephalus ( s. str.) parvulus group

Diagnosis. Elytron with regular punctures of 11 rows and pronotum distinctly punctured. Upper side seems glabrous or metallic, but with distinct punctures, sometimes stronger and closer, or sometimes finer ( Figs. 1 and 2 , punctures on the pronotum of this species group). These characteristics and character combination can distinguish the species group from the others.

According to our studies after checking the specimens maintained at IZ-CAS, and for some, based on the literature, we included in this species group the following 10 species listed below (of them, seven ones known before this study, one new country record to China, and two new species described here):

Cryptocephalus ( s. str.) guttifer Suffrian, 1854

Cryptocephalus ( s. str.) limbatipennis Jacoby, 1885

Cryptocephalus ( s. str.) melanoxanthus chotanensis Jacobson, 1896

Cryptocephalus ( s. str.) mitchyi Chûjô, 1954

Cryptocephalus ( s. str.) ngae Gressit, 1942

Cryptocephalus ( s. str.) parvulus O. F. Müller, 1776

Cryptocephalus ( s. str.) tetradecaspilotus Baly, 1873

Cryptocephalus ( s. str.) inhumeralis Pic, 1922 ( New country record to China)

Cryptocephalus ( s. str.) longwangshanus Duan, Wang & Zhou , sp. nov.

Cryptocephalus ( s. str.) yangae Duan, Wang & Zhou , sp. nov.
