Two new species of Hecuba Schumacher, 1817 (Bivalvia: Donacidae)

Author: J.G.M. Raven
Basteria, 88 (1): 1-5Published:

Abstract

In addition to the three extant species of Hecuba Schumacher, 1817 discussed in Raven & Dekker (2022, Basteria, 86 (2): 96-113) a fourth extant species occurs in eastern Sumatra, Indonesia, herein described as Hecuba parva spec. nov. A fossil from the Miocene of India is herein described as H. mukerjeei spec. nov. The type species of Hecuba is corrected to Venus scortum Linnaeus, 1758. A correction is made regarding the reference to Rumphius in Raven & Dekker (2022).

Microstellaria juliae – a remarkable new subfamily, new genus and new species in the Pyramidellidae (Gastropoda)

Abstract

A new genus and species within the Pyramidellidae are described from offshore coral reefs at various localities in Indonesia and from the Royal Charlotte atoll in the South China Sea: Microstellaria juliae gen. et spec. nov. Thus far only dead specimens have been found. The remarkable discoidal, planispiral shells with regularly placed projecting spines appear to be miniature versions of Stellaria Möller, 1832 (family Xenophoridae) or juvenile Astraea Röding, 1798 (Turbinidae). The heterostrophic protoconch at an almost 90o angle to the teleoconch demonstrates its placement within the Pyramidelloidea, however, the shells have some unique features. The internal septa in the early part of the teleoconch have not been recorded before from the Pyramidelloidea. They are interpreted as preventive measure in case the protoconch is damaged. The planispiral shape is exceptional within the Pyramidellidae, albeit not unique. The projecting spines along the periphery and on the aperture are unique within the superfamily. Therefore the genus is placed within a new subfamily Microstellariinae subfam. nov., currently within the Pyramidellidae, but it could constitute a separate family within the Pyramidelloidea.

New Muricidae (Mollusca, Gastropoda) from the Miocene of Java (Indonesia)

Abstract

A well-preserved muricid gastropod fauna is described from Wonosari, Gunung Kidul Regency, Special Region of Yogyakarta, Java, Indonesia. In the Muricinae subfamily, six species of Chicoreus are recorded, of which three species and one subspecies are new: C. (Triplex) javanus spec. nov., C. (T.) solidus spec. nov., C. (T.) martini spec. nov., C. (T.) altenai dekkersi subspec. nov., C. (T.) juttingae (Beets, 1841) and C. (Rhizophorimurex) cf. capucinus (Lamarck, 1822). A new species of Chicomurex is described: C. parvus spec. nov. Vokesimurex wanneri (Martin, 1916) is also recorded and a lectotype is designated herein for this species previously recorded from the early Miocene of Central Java. In the subfamily Aspellinae, Dermomurex (s.s.) wanneri nom. nov. is proposed for Murex acuticostatus Wanner & Hahn, 1935 (not Murex acuticostatus Gümbel, 1861), originally described from the early-middle Miocene of Central Java (Indonesia) and also found in Wonosari.

Results of the Rumphius Biohistorical Expedition to Ambon (1990). Part 18. The Rissoinidae and Zebinidae (Gastropoda: Caenogastropoda)

Authors: W.J.M. Sleurs, H.L. Strack
Basteria, 85 (1): 34-58Published:

Abstract

This paper reviews the Rissoinidae and Zebinidae collected during the Rumphius Biohistorical Expedition to Ambon, in 1990, with additional material collected by the second author (hls). In all, 30 species belonging to the family Rissoinidae and 12 species belonging to the family Zebinidae are recognised. The wellknown species are listed with a short synonymy and the poorly known species are redescribed in detail and illustrated. The biogeographical relationships of the rissoinid and zebinid fauna from Ambon are briefly discussed.

Semiricinula preturbinoides spec. nov., a new species from the Miocene of Java (Gastropoda: Muricidae)

Authors: B.M. Landau, J.G.M. Raven, A.E. Breitenberger, A.M. Dekkers
Basteria, 84 (4/6): 131-134Published:

Abstract

A new species of Semiricinula, S. preturbinoides spec. nov. is described from the Langhian Middle Miocene of Java, Indonesia, as part of a series describing the assemblage found at Wonosari, and the presence of Taurasia striata (de Blainville, 1832) is recorded from these same beds.
