TYPE SPECIES. — Solenopleura prantli Růžička, 1946, by original designation. DIAGNOSIS. — Glabella bluntly conical, not reaching frontal border; three pairs of shallow glabellar furrows; arched preglabellar area; arched cephalic border, widest in front of cranidium; ornamentation covering cranidium except for furrows and palpebral lobes; occipital ring with small node; thorax of 14 segments; pygidium small, with four to five rings on axis (based on Šnajdr 1957, 1958; Álvaro et al. 2004, with modifications). REMARKS The genus Jincella is closely related to the genus Solenopleura Angelin, 1854. Jincella has variously been treated as a junior synonym of Solenopleura (e.g., Rushton & Berg-Madsen 2002), while other authors (e.g., Geyer 1998; Álvaro et al. 2004) separated the two based on the relative convexity of the glabella, fixigenae, anterior border and eye lobes. Ornamentation is another reliable diagnostic characteristic in Jincella , even though this has been questioned by Fletcher (2007), who ranked Jincella as a subgenus to Brunswickia Howell, 1937. Based on the original description of Howell (1937) and images of the specimens assigned to the genus Brunswickia , the shape of the cranidium in Brunswickia is narrower than that of Jincella . We here follow Álvaro et al. (2004) and interpret the presence of ornamentation of Jincella as a diagnostic characteristic. We therefore maintain the separation of Jincella from Brunswickia and Solenopleura and treat the genus as a member of Solenopleuridae, thus following e.g., Harrington et al. (1959), Courtessole (1973), Geyer (1998) and Álvaro et al. (2004).
