Etymology: Diaphus: Greek, dis, dia = through + Greek, physa, phyo = to beget, to have as offspring (Ref. 45335).
Eponymy: Ernest William Lyons Holt (1864–1922) was a British marine naturalist, ichthyologist and soldier who served in the Nile Campaign (1884–1885) and the Third Burmese War (1886– 1887) during which he was invalided home. [...] (Ref. 128868), visit book page.

Eastern Atlantic: Bay of Biscay including the Mediterranean to Liberia (uncommon between Morocco to Mauritania). Elsewhere in the Atlantic Ocean, south and east of 50°N and 45°W to 35°N, but east of 35°W to about 20°N. Indian Ocean: two specimens at 29°30'S, 64°56'E.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 5 - ? cm
Max length : 7.0 cm SL male/unsexed; (Ref. 4479); max. published weight: 5.80 g (Ref. 126117)
High-oceanic, found between 225-650 m during the day and between 40-275 m at night exhibiting size stratification with depth and with adult females below 450 m (Ref. 4479). Depth range from 300-777 m in the eastern Ionian Sea (Ref. 56504). Large juveniles, sub-adults and adults from the Mediterranean are known to be migratory (Ref. 4775).
