Hemiparacytheridea Herrig, 1963

Type species. Hemiparacytheridea occulta Herrig, 1963

Diagnosis. A genus of the subfamily Cytherurinae with a small carapace of subrectangular or quadrate lateral outline commonly with long caudal process above midheight. Posteroventral and subcentral tubercle present often forming a bitubercular alar structure. Eye tubercle present or absent. Normal pore canals large and regularly distributed. Muscle scars consist of four subovate adductor scars in a vertical row and a subreniform frontal scar ahead of the row. Hinge, in right valve, consists of a small circular anterior terminal tooth, posterior tooth very much reduced or absent, and a locellate median groove expanded posteriorly.

Comparisons. This genus lacks the solum pore clusters and distinct posterior terminal hinge element of Eucytherura . Tuberculocythere Colalongo & Pasini, 1980 also lacks these features and is considered to be a strongly tuberculate form of Hemiparacytheridea .
