Diagnosis.

Males of this genus is similar to Lobizon Piacentini & Grismado, 2009 in having a long embolus resting in a groove of a broad terminal apophysis, but can be distinguished by several key characters: (1) a strongly sclerotized basoembolic apophysis (vs. weakly sclerotized and lamellar in Lobizon); (2) both membranous terminal apophysis 1 (TA 1) and sclerotized, groove-like terminal apophysis 2 (TA 2) are present (vs. TA 2 only in Lobizon); and (3) a median apophysis with three arms (AA, RA, PA). Females can be recognized by a spermatheca with compact stalk and small protruding head (vs. stalk sinuous in Lobizon) (Wang et al. 2021; Wang et al. 2024).
