Genus Anasyntormon Parent

Anasyntormon Parent, 1932: 114 . Type species: Anasyntormon secundus Parent [Oriental], designation by Dyte, 1975: 245.

Remarks. Anasyntormon was erected by Parent (1932) and includes the Oriental type species A. secundus and A. exceptus (Becker) , the latter of which was originally described in Syntormon . Parent (1932) placed Anasyntormon in the Rhaphiinae and indicated that the genus can be distinguished from Syntormon by its free hypopygium and convergent wing veins R4+5 and M. In the original description of A. exceptus Becker (1922b) noted that the hypopygium and wing venation is similar to that of Hercostomus . The unique male holotype of A. exceptus was deposited in the Hungarian Museum and was destroyed during the Hungarian Revolution of 1956 (M. Földvàri, pers. comm.). Parent (1932) described A. secundus based on an undisclosed number of males from Sumbawa, Indonesia collected during the Rensch Expedition. These specimens are apparently at Martin Luther Universität, Halle de Salle, Germany, with the other material from the Rensch Expedition; however, to date, I have not been able to confirm this and have not seen the specimens.

Ulrich (1981) transferred Anasyntormon to the Dolichopodinae based on the examination of a male of A. secundus in the BMNH. Unfortunately, I was unable to locate this male during a visit to the BMNH in July 2000 and have not seen any other specimens. Ulrich (1981) made the following comments on A. secundus (translated from the original German): “The examined male [ A. secundus Parent, London ] is similar to a typical Hercostomus in habitus and examined characters. This similarity is not contradicted by the apical arista. The finger­like projection of the second antennal segment (as seen in Syntormon ) is absent and in its place is an axial nipple (similar to the “collar­shaped prolongation” of Lundbeck 1912 known from the Dolichopodinae and other subfamilies). Anasyntormon is congeneric with Hercostomus or at least closely related.” Negrobov (1980) also examined material of Anasyntormon and, like Ulrich (1981), concluded that the genus is a dolichopodine.
