Ascaltis compacta Schuffner, 1877 

Schuffner’s description (1877: 404, pl. 25 fig. 9) points towards Arturia  or Ernstia. It is obviously close to Arturia sueziana Klautau & Valentine, 2003  , but these authors pointed out that Schuffner’s drawing does not show the presence of water-collecting tubes, which are so characteristic of A. sueziana  . The additional argument for specific distinction, viz. the greater size of the actines of the triactines and tetractines, is not very convincing. In the absence of the type, which appears to be lost, it seems best to reassign A. compacta  to Arturia  as Arturia compacta  .
