Genus Acryptolaria Norman, 1875 Acryptolaria Norman, 1875: 172, pl. 12 figs 1, 2. Scapus Norman, 1875: 173, pl. 12 figs 1, 3 (type species: Scapus tubulifer Norman, 1875). Oswaldaria Stechow, 1921: 30 (type species: Cryptolaria crassicaulis Allman, 1888). TYPE SPECIES. — Acryptolaria andersoni Totton, 1930. DIAGNOSIS. — Lafoeidae with adult colonies consisting of branched, polysiphonic, erect stems with a main, hydrothecate central axial tube and a series of accompanying accessory tubes. Branches also polysiphonic, originating from secondary tubes. Polysiphony decreasing distally, but almost reaching distal end. Hydrothecae only present on main axis of stem and branches. Hydrothecae alternately arranged, forming two longitudinal rows (with the exception of A. tetraseriata n. sp.), usually in one plane. Hydrotheca tubiform, partially adnate to branch; without diaphragm. Nematothecae absent. Gonothecae aggregated to form a coppinia, with or without defensive tubes. Gonophores fixed sporosacs. Cnidome consisting of two categories of nematocysts: large putative macrobasic mastigophores and small putative microbasic mastigophores. REMARKS For a wider discussion on the genus see Peña Cantero et al. (2007). These authors completely redescribed the type specimens of the known species, with the exception of A. andersoni and A. rectangularis (Jarvis, 1922), for which no type material could be located; it is probably lost. According to Peña Cantero et al. (2007) the genus after their revision included 16 valid species. However, A. andersoni , type species of the genus, and A. rectangularis are insufficiently known, although the coppinia of the former, that was mistakenly described as a new species of hydroid ( Scapus tubulifer Norman, 1875), is known. SPECIES INCLUDED A list of species originally referred to Acryptolaria is given by Peña Cantero et al. (2007); they also list the species that actually belong to other genera of Lafoeidae, as Cryptolaria , Grammaria or Zygophylax .
