Etymology: Nemichthys: Greek, nema, -atos = filament + Greek, ichthys = fish (Ref. 45335); larseni: Named for Verner Larsen, who began the study of this species while at the University of Copenhagen.
Eponymy: Verner Larsen is a Danish ichthyologist, who began revising Nemichthys whilst still a student at the University of Copenhagen, and who, according to the etymology, “…generously handed over his material” to the authors “…when he was unable to finish [...] (Ref. 128868), visit book page.

وصف مختصر
مفاتيح التعريف | الوصف الخارجي | قياسات المظهر الخارجي
الأشعة الظهرية الناعمة (المجموع) : 173 - 222; أشعه شرجية لينه: 164 - 208. Most easily distinguished from N. scolopaceus by its pale color; has more postorbital and preopercular pores. Rectangle formed by the lateral line pores is shorter and higher than in scolopaceus. Resembles N. curvirostris in its pale color but the subcutaneous dark bars are not as evident. May be instantly distinguished from curvirostris by the more numerous postorbital and preopercular pores and the much shorter and higher rectangle formed by the lateral line pores. Has smaller teeth than curvirostris.
Mesopelagic (Ref. 58302). Minimum depth from Ref. 58018.
