Indo-west Pacific, from Somalia and Madagascar to Japan, Indonesia, Australia and Fiji. Previous records from Singapore. Johnson (1962, 1979, as Synalpheus acanthitelsonis Coutière, 1905). Ecology. Coral reefs and associated habitats with abundant rubble and sponges, usually in interstices of dead and living coral heads, in sponges, in coral rubble crevices etc.; lower intertidal to 160 m, but typically found at a depth range of about 3–20 m. Remarks. Synalpheus hastilicrassus, as redefined by Banner & Banner (1975b), most likely represents more than one species. The taxonomic status of S. acanthitelsonis Coutière, 1905 and S. hastilicrassus var. acanthitelsoniformis De Man, 1920, both currently synonyms of S. hastilicrassus (see Banner & Banner, 1975b) needs a reappraisal. The vast majority of specimens from Singapore match S. acanthitelsonis, which was separated from S. hastilicrassus by the much more produced posterolateral angles of the telson, among other characters (Coutière, 1905). Johnson (1962) reported this species as S. acanthitelsonis, being “one of the commonest species of Synalpheus in the Singapore area ... generally distributed on beaches below mid-tide level and in shallow offshore waters wherever the bottom has crevices in which it can live”. Johnson’s material came from Labrador Beach (intertidal, crevices in honeycomb rock), Pulau Sudong (coral heads at 1–2 m), Johor Shoals (crinoid grounds at ~ 18 m) and Kuala Johor off Angler Bank (18–27 m). The abundant CMBS material was collected at many shallow and deep-water stations in the Strait of Singapore and eastern and western Straits of Johor. Synalpheus hastilicrassus (= S. acanthitelsonis of Johnson) is today one of the most common snapping shrimps of Singapore.
