Ctenodesma bersinara Zieritz et al., sp. nov. View in CoL
( Fig. 4 View Figure 4 )
Type locality: Sungai Rempangi (Pawan Drainage), 17 km SSW of Randau, Ketapang Regency, West Kalimantan, Indonesia ( Fig. 5B View Figure 5 ).
Type: Holotype, FKH_MFw_x541.
Material examined: One lot: FKH_MFw_x541.
Diagnosis: Morphologically very similar to other Ctenodesma species but is less elongate, has a sharper posterior ridge, and strong green rays on posterior slope and shell disk.
Description: Shell thin, with fine wrinkles extending from posterior ridge, fine sculpture on dorsal third of shell disk; subrhombodial shell outline with slightly biangulate posterior slope; ventral margin slightly rounded, dorsal margin angled upwards, umbo even with hinge line; periostracum yellowish brown with green rays of variable thickness. Pseudocardinal teeth, elongate, moderately thick, one tooth in left valve, two teeth in right valve. Lateral teeth long, straight, two in left valve, one in right valve; Nacre bluish white, with yellowish brown tint near umbo and posterior slope. Soft anatomy unavailable for study.
Distribution: Known only from the type locality in West Kalimantan ( Fig. 5B View Figure 5 ).
Etymology: The species is named after its strong green rays using the Bahasa Indonesian word ‘ bersinar ’, meaning ‘radiating’.
Remarks: This species is known from a single small specimen (~ 40 mm), making meaningful morphological description of the species very difficult.
