Etymology. The specific epithet reflects that the species occurs in the coral hosts Ctenactis albitentaculata and C. echinata. For the purposes of nomenclature, it is herewith declared (under ICZN 1999 Article 11.3) as an arbitrary combination of letters to be used as a word; thus, the spelling presented here is to remain unchanged.
Type material. Holotype female (RMNH 90066 *), found in the mushroom coral Ctenactis echinata; Indonesia, SW Sulawesi, Spermonde Archipelago, NW Lumulumu Island, 04°58′13″S 119°12′35″E.

Diagnosis. Among the Leptoconchus species with reduced and variable morphological characters and associated with fungiid corals, L. inalbechi sp. nov. is differentiated by a unique combination of nucleotides in the Cytochrome Oxidase I barcoding sequence (GB: EU215802, EU215803, EU215806–EU215808), as indicated by underlined letters in Fig. 48.
Shell. Holotype female (Figs. 39, 40) H 20.3 mm, W 25.5 mm (largest female); columellar callus covering most of surface of last whorl; outer lip with an obtuse angle, bordering a straight part at shell base. Male shell (Fig. 41) found with holotype H 12.3 mm, W 11.6 mm; outer lip curved more regularly. Apical part of shell distinctly protruding above apertural edge in female (Fig. 39), slightly less in male (Fig. 41).
Habitat. The snails and their egg capsules were found at 3–17 m depth, with the mushroom coral species Ctenactis echinata (Pallas, 1766) and C. albitentaculata Hoeksema 1989. The siphon pores are located on the underside of the corals.
Distribution. The range of Leptoconchus inalbechi extends from Indonesia to Palau.
