Editor's comment Metatiron Rabindranath (1972) was raised for Tiron brevidactylus (Pillai, 1957), a species lacking a mandibular palp, in contrast to the genotype T. spiniferus (Stimpson, 1853) which has a 3-article palp. Opinion has been divided on the validity of Metatiron
Rabindranath (1972), M. caecus Ledoyer, 1979, M. bonaerensis Alonso de Pina, 1998 and Thomas (1993, unpublished report) who transferred T. triocellatus Goeke, 1982, accept the separation while Just (1981) and Jazdzewski (1990) do not. The latter author argues for an amendment of the generic diagnosis to read ‘mandibular palp present or absent’.
Goeke (1982) and Hirayama (1988) do not refer to Rabindranath (1972). Barnard & Karaman (1991) recognise Metatiron (to include M. brevidactylus and M. caecus) but continue to define Tiron as having a 3-article palp despite earlier (Barnard, 1972) describing T. tropakis as lacking a mandible palp. Lörz & Coleman (2013) ignore the problem. They list twelve species in Tiron of which five, according to their key copied from Jazdzewski (1990), lack a palp (bellairsi, galeatus Hirayama, 1988, ovatibasis Hirayama, 1988, triocellatus, tropakis).
