Remarks.

Of the nine genera included in the Hatschekiidae , the most speciose genus is Hatschekia , with approximately 140 valid species so far. According to Uyeno and Nagasawa (2013), H. longiabdominalis may be separated from other congeners by having a fusiform trunk with posterior lobes, the urosome markedly projecting beyond posterior lobes of the trunk, and unique intercoxal sclerites of legs 1 and 2, which strongly project from the middle of the anterior margin and bear four blunt processes on the posterior margin. We observed all of these characters in our specimens.
