Rhysotritia clavata spiculifera Mahunka, 1991 .

Rhysotritia spiculifera: Niedbała 2001 .

Diagnosis — Measurements of paratype: prodorsum: length 205, height 83, width 157; setae: ss 56, in 88, le 63, ro 48, ex 8; notogaster: length 414, height and width 252, setae: c 1 45, c 1 /c 1 -d 1 =0.5, h 1 56, ps 1 53; length of genitoaggenital plate 144; length of anoadanal plate 182. Medium-sized species: colour yellow; surface of body punctuated. Prodorsum with simple lateral carinae; sensilli with well-separated, claviform head covered with small spines; other setae, with exception of exobothridial, ciliate; in> le> ss> ro> ex.
