costalis (Walker), 1837: 359

( Tetanocera) [Malloch 1933: 312]

HT: [Chile: Magallanes y la Antártica Chilena] “Port Famine.” NHMUK, unnumbered [examined by Steyskal 1966: 446]. The modern names of Port Famine are Fuerte Bulnes and Puerto Hambre/Puerto del Hambre (53°37’00”S 070°56’00”W)

Note: The sex of the holotype was unknown when Walker (1837) described it as “ abdomen ademptum,” meaning absent or taken. Steyskal (1966: 446) examined the holotype but did not comment on the missing abdomen. Nigel Wyatt (NHMUK) examined the specimen and confirmed (in litt. 3 May 2023 to WLM) that the abdomen is indeed missing from the holotype.
