Suture line with very narrowly lanceolate external lobe.

Material examined

Holotype

MOROCCO • Anti-Atlas, Mfis near Taouz, bed 7; Bockwinkel & Ebbighausen Coll.; illustrated by Bockwinkel & Ebbighausen (2006: text-fig. 30e–f); MB.C.3820.1.

Paratypes

MOROCCO • 7 specimens; Anti-Atlas, Mfis near Taouz, bed 7; Bockwinkel & Ebbighausen Coll.; MB.C.3820.2–MB.C.3820.8 .

Etymology

An acronym for a Kazakhstania species from North Africa.

Description

The species newly described here has been worked on in detail by Bockwinkel & Ebbighausen (2006), so reference can be made here to that description.

Remarks

Kazakhstania kana sp. nov. resembles K. evoluta, but differs in the broader, pouched external lobe, which is lanceolate and very narrow in K. evoluta . The other species of the genus have constrictions and are thus separated from K. kana .
