Remarks.

The two main characters distinguishing the new species are detailed in the above diagnosis. These characters are not present in any of the known species of Conganteoninae ( Olmi and Xu 2015; Xu et al. 2013).

Etymology.

The species is named sulcatum because the head is sculptured by many longitudinal subparallel keels.
