Remarks. Griffin (1976: 213, fig. 10a, as Rochinia nodosa ) provided a photograph of the holotype of L. nodosa from the Bohol Sea, which agrees very well with the series of specimens at hand, many from the type locality. The carapace of L. nodosa is covered by a very thick and dense tomentum masking the swollen regions, although the removal of the tomentum shows that the carapace has no plates but only tubercles at best. In this respect, it is very different from all other Oxypleurodon species. The raised regions are arranged as follow: a very inflated hepatic region, which is slightly directed dorsally; one larger cardiac tubercle surrounded by three sharp tubercles on each side and one above; one large epibranchial tubercle with a sharp point dorsally; one mesogastric tubercle and two tubercles on the epigastric region; one branchial swelling. The supraocular eave is elongated, forming a spine anteriorly and on the lateral border of the carapace, and there are two lamellar crests at the protobranchial position.

The G1 drawn by Griffin and Tranter (1986: 189, fig. 63g, h) shows the tip rounded, which is quite different from those of typical Oxypleurodon species ( Fig. 3 View FIGURE 3. G 1 s. A, B ).
