Etymology: Thryssa: Greek, thrissa, -es = shad (Ref. 45335).
Eponymy: Marasri Ladpli was the wife of the author. He dedicated the species to her for her “…patient sharing of my study of fishes, her encouragement, and her tolerance of my trips away from home.” (Ref. 128868), visit book page.
Environment: milieu / climate zone / depth range / distribution range
Ecologie
marien; brak water; diepte 0 - 50 m (Ref. 189). Tropical; 9°S - 15°S, 124°E - 131°E (Ref. 189)
Western Central Pacific: northern Australia.
Grootte / Gewicht / Leeftijd
Maturity: Lm ? range ? - ? cm
Max length : 6.9 cm SL mannelijk / geslacht onbekend; (Ref. 189)
Dorsale stekels (totaal) : 0; Anale stekels: 0; Anale zachte stralen: 26 - 28. Belly with 15 or 16 + 8 or 9 = 23 to 25 keeled scutes from isthmus to anus. Maxilla short, reaching to hind border of pre-operculum; first supra-maxilla short, about half length of second. Pseudobranch moderate. A diffuse dark saddle just before dorsal fin origin; no dark blotch behind gill opening.
Presumably marine, pelagic and coastal, but its very close similarity to T. aestuaria and T. brevicauda suggests that it may also enter estuaries. More data needed.
