Morpho-taxonomic analysis of Onchidium stuxbergii (Westerlund, 1883) and Onchidium melakense (Dayrat & Goulding, 2019) (Mollusca: Gastropoda: Onchidiidae) from the Karachi coast, Northern Arabian Sea

Species of this genus are readily recognized in the field by two diagnostic features: large conical papillae on the dorsal notum and long, slender ocular tentacles (Dayrat <i>et al</i>., 2019). Unlike related gastropods, Onchidium lacks dorsal branchial gills but bears eye spots on the dorsal papillae.</span></span></span></span></span></span></span></span> <span style="font-size:11pt"><span style="line-height:120%"><span style="text-autospace:none"><span style="font-family:Calibri,sans-serif"><span lang="TR" style="font-size:12.0pt"><span style="line-height:120%"><span new="" roman="" style="font-family:" times=""><span style="color:black">In this study, a morpho-taxonomic examination was conducted on two species, <i>Onchidium stuxbergii</i> (Westerlund, 1883) and <i>Onchidium melakense</i> (Dayrat & Goulding, 2019), collected from the Karachi coast, Northern Arabian Sea. This investigation represents the first taxonomic record of Onchidium species from this region, thereby contributing new insights into the distribution and morphological variation of the genus.</span></span></span></span><span dir="RTL" lang="AR-SA" style="font-size:12.0pt"><span style="line-height:120%"><span new="" roman="" style="font-family:" times=""><span style="color:black"></span></span></span></span></span></span></span></span>
