Diagnosis

Diameter 1.78–1.90 mm, 50–52 podous rings. Gonopods: lateral incision of coxa (li) deep with rounded bottom, curving distad, basally delimited by triangular tooth; apical palette (pa) obliquely rounded, much longer than broad; telomere describing a c. 270° curve in almost one plane; mesal-posterior lamella of telomere (mpl) moderately developed; anterior margin of telomere without a triangular tooth; telomere tip with densely microspiculate margins and internal surface.

Etymology

The name is a Latin noun, here in apposition, composed of longi- (long) and pala (palette), and refers to the shape of the apical part of the gonopod coxa.
