- Abstract
We erected a new genus (Grylloprimevala Zhou & Ren gen. nov.) and defined a new species (Grylloprimevala jilina Zhou & Ren sp. nov.) from a natural cave in the primeval forest of Jilin Province, China, according to the morphological, behavioral, and molecular evidence. Grylloprimevala gen. nov. is distinguishable from other genera of Grylloblattodea primarily by morphological characters, including the slightly concave posterior margin of the pronotum and no poorly sclerotized zones, six intramarginal and nine intermarginal setae on the cervical sclerite, one tooth on the lacinia, no pulvilli on tarsal segments, and a symmetrical epiproct with a pointed triangular and middle‐depressed median projection on the posterior margin. Based on the morphological features mentioned above, we further identified a new species, G. jilina sp. nov. At the aspect of behavior, G. jilina sp. nov. displays the typical characteristics of troglobites, including degraded visual senses, developed body surface sensors, and predation between individuals. Furthermore, molecular phylogenetic analyses also supported the morphological delimitation of G. jilina sp. nov. due to the separate clade of G. jilina sp. nov. Our results provide materials for the determination and conservation of Grylloblattodea in China.
