A77C4E27FFE5FFDDFF78FAE2FBE3FE0C.taxon	diagnosis	Diagnosis: Shell tall, solid, slender, conical, white with pointed apex. Protoconch of type B, sometimes tending to C (van Aartsen 1977, 1981; van der Linden & Eikenboom 1992). Whorls slightly convex. Suture distinct, shallow- moderately deep, noticeably oblique. Axial ribs elevated, shouldered straight and orthocline to slightly prosocline. Interspaces much broader than ribs. Ribs continue more or less clearly down to base. Spiral sculpture of distinct ridges, distinct also crossing axial ribs, giving a grid-like appearance. Interspaces are equally broad or broader than ridges. Spirals continue to the base. Aperture oval, with distinct columellar tooth. Inner side of outer lip often with several prominent ridges. Umbilicus distinct. The combination of characters is not present in any other pyramidellid genus.	en	Lygre, Frøydis, Schander, Christoffer (2010): Six new species of pyramidellids (Mollusca, Gastropoda, Pyramidelloidea) from West Africa, introducing the new genus Kongsrudia.

A77C4E27FFE5FFDDFF78FAE2FBE3FE0C.taxon	discussion	Comments: There are several West African species that belong in this genus and are here formally transferred to the genus Kongsrudia: Pyrgulina approximans Dautzenberg, 1913 a; Chrysallida ersei Schander, 1994; Pyrgulina mutata Dautzenberg, 1913 b (nom. nov. pro P. lamyi Dautzenberg 1913 a non P. lamyi Dautzenberg & Fischer, 1906). Pyrgulina jullieni Dautzenberg, 1913 a is similar, but have a very marked shoulder on the whorls, and until further information is available, we refrain from including this species in Kongsrudia. According to Schander et al. 1999, Chrysallidinae comprises close to 50 genera. After comparing the species with available descriptions and illustrations of type species we have not been able to comfortably fit the above mentioned species in to any of those genera. The genus Kongsrudia shows some similarities to the genus Pyrgulina A. Adams, 1863 with the type species Chrysallida casta A. Adams, 1861 (Subsequent designation Dall & Bartsch, 1904), but the spiral sculpture in this genus is far less prominent, and the species of Pyrgulina also tends to be broader in outline. The genus Trabecula Monterosato, 1884 with the type species Trabecula jeffreysiana Monterosato, 1884 is similar in outline, but lack the marked striations and the axial sculpture does not reach the base of the shells.	en	Lygre, Frøydis, Schander, Christoffer (2010): Six new species of pyramidellids (Mollusca, Gastropoda, Pyramidelloidea) from West Africa, introducing the new genus Kongsrudia.

The axial ribs and spiral ridges have narrower interspaces and the ridges are broader and continue all the way to the upper suture. The riblets seen on the inner side of the outer lip are not as prominent in K. approximans. Kongsrudia rolani n. sp. is similar to K. gruveli, for comparison, see this species.	en	Lygre, Frøydis, Schander, Christoffer (2010): Six new species of pyramidellids (Mollusca, Gastropoda, Pyramidelloidea) from West Africa, introducing the new genus Kongsrudia.

A77C4E27FFE4FFD8FF78FA98F8BEFEF2.taxon	discussion	Remarks: The shape and sculpture is similar to Kongsrudia gruveli (Dautzenberg, 1910), but the whorls are more convex and K. gruveli lacks the microsculpture. The axial sculpture of K. gruveli is more prominent, especially on the base. Kongsrudia approxiamans (Dauzenberg, 1912) and K. ersei (Schander, 1994) are similar, but they both have more convex whorls, lack the subsutural shelf and have broader spiral ribs that are more tightly spaced. Like the genus Afroturbonilla Peñas, Rolán & Schander, 1999, Kongsrudia is so far only known from off West Africa.	en	Lygre, Frøydis, Schander, Christoffer (2010): Six new species of pyramidellids (Mollusca, Gastropoda, Pyramidelloidea) from West Africa, introducing the new genus Kongsrudia.

A77C4E27FFE1FFD9FF78FC57FD32F875.taxon	discussion	Remarks: The size of the protoconch differ slightly in the two shells from station G 11. The interspaces between the ribs also differ slightly and one shell has ribs closer together. Turbonilla perezdionisi Peñas & Rolan, 1997 resembles this species, but has straighter whorls and lacks the subsutural shelf and shouldered axial ribs. The ribs of T. perezdionisi are also more sinuous and less opistocline than in T. krakstadi. Turbonilla melvilli Dautzenberg, 1912 shows some resemblance to T. krakstadi, but only the initial whorls are turreted in this species and the axial ribs are more tightly spaced. Turbonilla gradata Bucquoy, Dautzenberg & Dollfus, 1883 has more regular axial ribs and is less turreted than T. krakstadi. FIGURE 4 A – E. Turbonilla krakstadi n. sp.

Interspaces between spiral striae are broader in the middle of the whorl and more tightly spaced apically than abapically. Vertical grooves more tightly spaced apically gives finer sculpture there.

A77C4E27FFEBFFD2FF78FC0FF9AEF871.taxon	description	Description: Shell tall, solid, conical, milky white and shiny with pointed apex. A very diffuse colored broad band is seen in middle / lower half of whorls. Protoconch of type A-I, small and semi-submerged. Whorl almost straight, slightly turreted. Suture distinct, broad and channeled. Axial ribs elevated, strong almost straight, shouldered and orthocline or slightly opisthocline. Ribs and interspaces about equally broad. Ribs disappear at the periphery of the ultimate whorl or continue as diffuse and thin extensions on base. Spiral sculpture consisting of rectangular grooves, not equal or equidistant. Bands between grooves not equal, for the most part broader than grooves. Spiral grooves present on base. Aperture rhomboid. Inner lip slightly folded. No columellar tooth. No umbilicus.	en	Lygre, Frøydis, Schander, Christoffer (2010): Six new species of pyramidellids (Mollusca, Gastropoda, Pyramidelloidea) from West Africa, introducing the new genus Kongsrudia.

A77C4E27FFEBFFD2FF78FC0FF9AEF871.taxon	discussion	Remarks: This species shows a certain resemblance to Turbonilla abrardi Fischer-Piette & Nicklés, 1946, but the protoconch is less submerged and the suture is broader and deeper in Turbonilla alvheimi. The whorls are more convex and the axial ribs not as strong and not shouldered in Turbonilla abrardi. Turbonilla jeffreysi (Thompson, 1850) is more turreted and has a less pronounced suture, the axial ribs are narrower, not as tightly spaced and less strong. The grooves are also more narrow in T. jeffreysi. Turbonilla rufescens (Forbes, 1846) have slightly more convex whorls. The suture and sculpture differs in the same manner as T. jeffreysi.	en	Lygre, Frøydis, Schander, Christoffer (2010): Six new species of pyramidellids (Mollusca, Gastropoda, Pyramidelloidea) from West Africa, introducing the new genus Kongsrudia.
