Comment | This name was given by Campbell (1998) to material reported erroneously as T. fusca by Slevin (1939) and T. jani by Wilson and Meyer (1971) and Wilson (1985) [fide Wilson 1999]. |
Etymology | The name vulcani is derived from Vulcan, the name of the Roman god of fire, “in allusion to the habitat of this species on the Pacific versant of Guatemala which is dominated by a series of spectacular Quaternary volcanoes, some still active” (Campbell, 1998). |
