Type locality.

“Java” (from the title).

Material examined.

W-Java, Djampang, 2000', leg. H. Fruhstorfer, 1893, coll. O. Boettger, SMF 57197 (syntype, labelled as holotype [number of available shells was not mentioned in the original description]); Java, Djampong (?), Res.: Preauger-Regentschappen, leg. ??? bauer (label not readable), coll. Oberwimmer, NHMW 111538 (3 shells).

Remarks.

The spire is high, but the protoconch is relatively low, it is rather matte, without spiral lines; R1 with some spiral lines, especially at the end of the region; There are widely spaced, strong ribs on R1 which are bunt at the beginning, but sharp at the end of the region; R2 short, with elevated, sharp, widely spaced ribs with some weak spiral striation between the ribs.

This species fits in the genus Chamalycaeus as well as into Pincerna . It is tentatively placed here due to the elevated spire. Further studies should focus on its systematic relationships.
