Etymology: Psilotris: Greek, psilos = hairless + Greek, thrix = hair (Ref. 45335); laurae: Named for Laura Albini, wife of Adriaan ‘Dutch’ Schrier, the owner of Substation Curacao (Ref. 113825).
Eponymy: Laura Albini was the wife of Adriaan ‘Dutch’ Schrier, owner of Substation Curacao, through whose efforts new, tropical, deep-water species are being discovered; Laura generously fed and hosted numerous researchers during their visits to Curacao. (Ref. 128868), visit book page.

Bestämningsnycklar | Morfologi | Morfometri
Mjukstrålar i ryggfenan (totalt) : 9; Mjukstrålar i analfenan: 8; Ryggkotor: 27 - 7. This species can be distinguished by the following set of characters: D1 VII, with spines 1-4 slightly elongate; D2 I, 9; A I, 8; elongate pointed pectoral fin with 18 rays; pelvic fins separate, no anterior frenum or membrane connecting 5th rays, rays 1-4 branched once, 5th ray unbranched and one-quarter the length of fourth ray; no scales on sides of body or head; no modified basicaudal scales; papillae row 5s/5i connected forming a single row at the anterior of row b, interorbital papillae row pc’ with two papillae; head and preopercle canals and pore absent; one anal-fin pterygiophore inserted anterior to haemal arch. Colouration: distinct five conspicuous thin bars along trunk, bars bright yellow in life or black in preserved specimens (Ref. 113825).
Cross section: oval.
Known specimen was found inside a glass bottle collected along a sandy slope ca. 114 -137 m depth (Ref. 113825).
