Carapace small, subhexagonally elongated in outline, maximum width at base of epibranchial region, dorsal surface weakly convex in both directions. Orbitofrontal margin wide, only partially preserved. Front narrow, bifid, with long, divergent spines. Lateral margins broadly arched, lateral spines incompletely preserved. Posterior margin strongly concave, notably shorter than orbitofrontal margin. Mesogastric region small, markedly rhombohedric in shape, well defined by furrows, anterior process narrow, ridged, not reaching base of front. Protogastric region clearly subdivided into 3 isolated, flat-topped lobes. Epigastric regions elongated, joining central protogastric ridge. Urogastric region V-shaped, with lateral portions extending obliquely forwards. Hepatic region with 2 notable small protuberances; anterior one conical, below orbital margin, posterior one larger, slightly elongated. Cervical groove well-defined, deeper at axial portion, interrupted by axial carina. Epibranchial region divided into 3 strap-like lobes; anterior portion subtriangular, median portion near straight, directed obliquely towards lateral margins, fairly well separated from urogastric lobe, posterior portion arched. Cardiac region relatively narrow, elongated, anterior portion laterally bounded by deep branchiocardiac grooves. Continuous axial carina along carapace fairly salient, rounded. Posterior half of carapace, strap-like lobes covered by fungiform granules, markedly enlarged on axial carina; grooves, furrows in anterior half of carapace densely covered by minute setal pits.
