Diestotini Mulsant & Rey 1871

Tribe Diestotini Mulsant & Rey, 1871 Remarks. The morphological definition of this tribe is not clearly defined. Ashe (2001) defined Diestotina (treated as a subtribe of Homalotini at that time) with the following characteristics: tarsal formula 4-4-5, labial palps with two palpomeres, unusually long and filiform or stylate, sutures between palpomeres indistinct in many taxa; ligula divided into two lobes apically; mesocoxal cavities broadly separated by broad meso- and metaventrite processes; metaventrite process as long as, or longer than, mesoventrite process. Asenjo et al. (2019) transferred six genera to Diestotini from Autaliini or Homalotini without any discussion. Presumably, the tarsal formula, the shape of the labial palps, and the shape of the spermatheca are important features for distinguishing this tribe.
