Saussurella brevifrons sp. nov. from Northern Thailand, with Taxonomic Notes for the Genus (Orthoptera: Tetrigidae)

ABSTRACT: Saussurella brevifrons sp. nov. Zha is reported from northern Thailand. The species is similar to S. decurva and S. javanica, but differs from the former by its anterior margin of vertex not protruding forward, lower margin of anterior pronotal process lacking hooked tip, and acutely angled posterior angle of lateral lobe; and from the latter by its wider vertex, larger body size and elongate posterior pronotal process. We describe it with photographs and ecological information. For the taxonomy of the genus Saussurella, we suggest a uniform standard for the measurement of the length of anterior pronotal process, and consider the variation of the anterior margin of vertex as an important taxonomical character.
