Etymology: Lestrolepis: Greek, lestris, -idos = bandit + Greek,lepis = scale (Ref. 45335); nigroventralis: Name from Latin 'niger' meaning black and 'ventral' means lower part of body, referring the broad margin on abdomen ridge..
Environment: milieu / climate zone / depth range / distribution range

Description synthétique
Morphologie | Morphométrie
Rayons mous dorsaux (Total): 9; Rayons mous anaux: 41 - 43; Vertèbres: 94 - 98. This species is distinguished by the following characters: a relatively slender body, its body depth 15-19 times in SL; dorsal-fin origin at about midline of distance between the origins of pelvic and anal fins (V-A), the distance between the origins of pelvic and dorsal fins (V-D) 46.8-55.0% of V–A; pelvic-fin origin (VFO) at or slightly behind the midline of the fish, the prepelvic length 50.6-53.2% SL; vertebrae: prehaemal 32-35, prepelvic 33-35, preanal 53-57, caudal 60-66, total 94-98; lateral-line scales 75-81; the abdomen ridge with broad black margin (Ref. 121637).
Collected by midwater trawl from surface to less than 100 meters, suggesting that it is a mesopelagic species that may have diurnal vertical migration. Stomach contents have myctophids or other pelagic fishes such as Bregmaceros spp. than sakura shrimps (Lucensosergia lucens) (Ref. 121637).
