A new species of Ceroplastes (Hemiptera: Coccomorpha: Coccidae) from southwest China evidenced by morphological and molecular data, with a discussion on the variation in the number of clear areas in the C. floridensis species-group

Key Points

A new species, C. planoides, has been described using both morphological and molecular data.
Phylogenetic analysis reveals the distinct monophyly of C. planoides compared to other Ceroplastes species.
A key for identifying Ceroplastes species in China is included, addressing variances in the C. floridensis group.
Findings on morphology and molecular data contribute to the understanding of Coccidae diversity in China.

Abstract

A new species of wax scale, Ceroplastes planoides Li & Wang, sp. nov. (Hemiptera: Coccomorpha: Coccidae), from Yunnan Province, China., is described and illustrated. Phylogenetic analysis based on COI and 28S genes confirms the monophyly of this new species. A key to the currently known species of the genus Ceroplastes in China is provided, along with a discussion on the variation in the number of clear areas within the C. floridensis species group.
