Description. See Salgado-Barrágan et al. (2014).

Color in life. Body semitransparent, with red chromatophores throughout; chromatophores densest on antennal and antennular peduncles, dorsal surface of carapace, chelipeds, uropods, telson, and on anterior margins of abdominal somites where they form distinct reddish transverse bands; major chela distally hyaline-white ( Fig. 20C ).

Type locality. Estero Pérula , Chamela, Jalisco, Pacific coast, Mexico .

Distribution. Tropical eastern Pacific region: Jalisco, Mexico ( Salgado-Barrágan et al. 2014) and Nicaragua ( Felder et al. 2003; present study).

Ecology. Obligate burrow cohabitant of callichirid ghost shrimps in the genus Lepidophthalmus : associated with L. bocourti (A. Milne-Edwards, 1870) in Mexico and Nicaragua ( Salgado-Barrágan et al. 2014; present study) and with L. natesi Felder & Robles 2015 in Nicaragua.

Remarks. Specimens of L. corderoae from Nicaragua morphologically matched the description of this species, which was based on material from Mexico. Additionally, the genetic sequences generated from Nicaraguan specimens closely matched the 16S sequence of a Mexican specimen published by Salgado-Barrágan et al. (2017), leaving no doubt that the Nicaraguan material represents the same species.

Leptalpheus corderoae is a member of the Leptalpheus axianassae group, being easily distinguished from L. axianassae and L. azuero by the presence of large, distinct tubercles on the ventral margin of the major chela, and from L. hendrickxi most easily by the presence of adhesive disks on the major chela.
