Rogers, D. Christopher, Dunn, Ann, Price, W. Wayne (2019): A review of Dendrocephalus (Dendrocephalinus) (Crustacea: Anostraca) with the first records of male-male anostracan aggressive competition. European Journal of Taxonomy 509: 1-14, DOI: 10.5852/ejt.2019.509
Remarks This species is unique in that the 2 A sub-branch (the apical branch) is absent, and sub-branch 2 V and 1 D are identical. The female shares the elongated brood pouch form with D. proeliator sp. nov. The only member of the subgenus occurring outside the extreme southeastern USA: all records are from southern, coastal Texas. All known locality substrates have 10 – 15 % calcium carbonate and 2 – 8 mS / cm salinity (Rogers 2014 b). So far, this species is known from three nearby locations, all seem to be on either private land or in public right of ways (Belk & Sissom 1992). Due to the limited distribution of D. acacioidea, this species meets the IUCN red list CR B 1 a, b species criteria (IUCN 2000), which means the species is Critically Endangered, with an extent of occupancy less than 100 km 2, and a projected decline in extent of occurrence.
