TYPE SPECIES. — Trilonche vetusta Hinde, 1899 ( Hinde 1899a: 48, pl. 8, fig. 18).

AGE AND LOCATION OF TYPE MATERIAL. — Middle Devonian (Givetian), Yarrimie Formation, New South Wales, Australia.

TAXON CODE. — 127.

STATUS. — Valid.

DIAGNOSIS. — “The test consists of two concentric latticed spheres, with three radial spines at equal or unequal distances apart. Secondary surface spines are also sometimes present.” ( Hinde 1899a: 47).

EMENDED DIAGNOSIS. — “Two or more, well developed, spherical or sub-spherical shells, and an internal, six-rayed double spicule. When secondary spines are present, the six spines developed from the rays of the internal spicule are generally considerably more robust and are easily recognizable as main spines. Up to six spines may be present.” ( Aitchison & Stratford 1997: 374).
