Tribe Neurotomini Benson, 1945

The representatives of this tribe are characterized as follows ( Shinohara 2002b): head with lateral sutures divergent forward and not connected with antennal furrows ( Fig. 1 : 1a); tarsal claws elongate (e.g., Figs 21h , 23h , 24h , 26h ); forewing with vein Scl absent ( Fig. 1 : 1b); abdominal sternum 7 in female not strongly convex, with paired rounded ridges apically, enclosing rather small triangular marginal depression (fig. 4E–G in Shinohara 2002b); lancet with lamnium enlarged ( Fig. 1 : 1c).

Two postulated autapomorphies, the absence of vein Scl in the forewing and the enlarged lamnium of the lancet of the ovipositor, may support the monophyly of this tribe. In our molecular analyses using COI and NaK sequences ( Figs 15, 16 ), Neurotoma was also retrieved as monophyletic with 100% UFBoot support.

The Neurotomini contains a single genus, Neurotoma , in the extant fauna.
