Abstract
Laevifaciesquadrialatagen. et sp. nov. is described from Hainan Province, China based on morphological data. COI data (DNA barcodes) is utilized to confirm the sexual dimorphism occurring in Laevifaciesquadrialatagen. et sp. nov.Melanozosterianitida Brunner von Wattenwyl, 1865, is reported from Guangxi Province, China. A key to the Chinese Polyzosteriinae is provided.
Highlights
Polyzosteriinae is a relatively species-abundant subfamily in the Blattidae
The Australian Polyzosteriinae exhibit the best examples of aposematic coloration
Sexual dimorphism is very common in cockroaches, some of which beinng so extreme that it is a challenge for taxonomists to match the two sexes (Roth 1992)
Summary
Polyzosteriinae is a relatively species-abundant subfamily in the Blattidae. Some species have pits or tubercles scattered on the pronotum (Rentz 2014), short tarsi and large pulvilli and arolia (Mackerras 1968b). Members of Polyzosteriinae were firstly mentioned by Burmeister (1838), with the establishment of genus Polyzosteria Burmeister, 1838. Tepper (1893) erected the subfamily Polyzosteriinae with two genera, Polyzosteria and Platyzosteria Brunner von Wattenwyl, 1865.
