organism: Carpilius convexus
attributes.tag: isolate
attributes.value: The broad, transversely oval carapace is distinctly convex and has a very smooth dorsal surface with ill-defined regions. Its anterolateral margin is longer than the posterolateral margin, a blunt tooth is present at their junction. The front is deflected downwards, its anterior margin straight in dorsal view, and bears a prominent median lobe that is feebly notched in the middle. The large chelae of the first pair of legs (chelipeds) are smooth, stout and unequal: the major one has a massive palm and fingers with an obtuse tooth near their base, while the minor cheliped is relatively smaller and thinner and without a tooth. The walking legs are thin and smooth, their last segment (dactyl) elongate and slender, with a dark brown cuticular claw at the tip. In males, the abdomen is narrow and elongate, with the third to fourth segments fused, whereas the abdomen of females is oblong. The distinctive coloration, which remains even after preservation, is yellow-orange or red to reddish brown, with irregular patches of dark brown on the dorsal surface of the carapace.
