Etymology. The specific epithet reflects that the species has been found exclusively in corals of Herpolitha limax. For the purposes of nomenclature, it is herewith declared (under ICZN 1999 Article 26) as not to be treated as a Greek, Latin or latinized word; thus, the spelling presented here is to remain unchanged.

Diagnosis. Among the Leptoconchus species with reduced and variable morphological characters and associated with fungiid corals, L. inlimax sp. nov. is differentiated by a unique combination of nucleotides in the Cytochrome Oxidase I barcoding sequence (GB: EU215829–EU215833, EU215884), as indicated by underlined letters in Fig. 48.
Shell. Holotype female (Figs. 33, 34) H 19.1 mm, W 22.8 mm; columellar callus covering most of surface of last whorl; lower part of outer lip with obtuse angle at shell base. H and W of largest female shell 20.3 mm and 22.1 mm, respectively, versus H 13.2 mm and W 10.6 mm for largest male (found with holotype; Fig. 35). Apical part of female shell slightly protruding above apertural edge (Fig. 33), apex of male shell protruding distinctly (Fig. 35).
Habitat. The snails and their egg capsules were found at 5–24 m depth, exclusively with the mushroom coral species Herpolitha limax (Esper, 1797). The siphon pores are located on the underside of the corals.
Distribution. The range of this species extends from the Philippines and Palau to Indonesia.
