Etymology: Stegastes: Greek, stegastos, -e, -on = covered (Ref. 45335).
Eponymy: The authors gave no etymological explanation, but the meaning of lacrymatus is ‘with tears’ and perhaps the allusion is explained as the authors dedicated this species to the “…memory of Mr. [...] (Ref. 128868), visit book page.

Short description

Taggstrålar i ryggfenan (totalt) : 12; Mjukstrålar i ryggfenan (totalt) : 16 - 18; Taggstrålar i analfenan: 2; Mjukstrålar i analfenan: 13 - 14.
Adults inhabit clear lagoon and seaward reefs, in areas with mixed coral and rubble or dead coral rocks. Feed mainly on benthic algae and associated small invertebrates and fish eggs (Ref. 7247). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Diurnal species (Ref. 113699, 12037). Minimum depth reported taken from Ref. 128797.
