Invasion Description
1st Record: Norfolk/VA/Hampton Roads (1924, MCZ 120444, Museum of Caomparative Zoology 2009)
At least some of the specimens in an earlier report (Fort Wool/VA/Elizabeth River (1877, Uhler 1878), may have been Bankia gouldi (Bartsch 1908).
Geographic Extent
Yorktown/VA/York River (1949-1959, Brown 1953, Wallour 1960); Fort Wool/VA/Elizabeth River (1877, Uhler 1878); Norfolk/VA/Hampton Roads (1944-1959, Brown 1953, Wallour 1960); Portsmouth/VA/Hampton Roads (1944-1959, Brown 1953, Wallour 1960); Cape Charles/VA/Chesapeake Bay (mouth) (Wallour 1960); Newport News/VA/Hampton Roads (1924, MCZ 121448, Museum of Caomparative Zoology 2009); Norfolk/VA/Hampton Roads (1924, MCZ 120444, Museum of Comparative Zoology 2009); 'a 300 m (1000 foot pier and 21-m (70 foot wide pier in Virginia'/VA/Chesapeake Bay (Abood et al. 1995, extensive shipworm damage, probably both from Bankia gouldi and T. navalis)

Regional Impacts
| Economic Impact | Shipping/Boating | |
| Impacts to wooden structures in Chesapeake Bay are probably due mostly to Bankia gouldi (Brown 1953; Scheltema 1954), but T. navalis is present in the lower Bay. One extensive project for shipworm repair involved a 300 m (1000 ft) long and 21 m (70 ft) wide pier in Virginia, in which many damaged pilings had to be replaced and more than 2,000 timber pilings were wrapped in plastic (Abood et al. 1995). | ||
