Type locality.

"Jagor aus Java" ( A. jagori ); "in montibus Nungnang insulae Javae" ( A. hochstetteri ); “südl. Celebes, bei Maros unweit Makassar" ( A. jagori var. minor ).

Material examined.

Java. Jagor, coll. Möllendorff ex coll. Martens, SMF 109304 (1 syntype of A. jagori , photographs examined); Java. coll. Rušnov ex coll. W. Blume, NHMW/71770/R/21 (18 shells).

Remarks.

Benthem-Jutting (1948) claimed that Alycaeus hochstetteri is a synonym of A. jagori . Neither she, nor we had a chance to examine the type specimens of A. hochstetteri , but we follow Benthem-Jutting’s view, which is based on that of Pfeiffer (1861). Hendriks et al. (2019) studied the phylogeography of S. jagori from Borneo. Given that the species is described from Java, the identity of the Bornean samples needs to be revised.

Protoconch glossy, without spiral lines; R1 with irregular, low ribs, very weak spiral striation in-between; R2 very short, with alternating darker/thicker and lighter/narrower stripes somewhat elevated from the surface; overall surface of R2 irregularly wrinkled.
