AllodinopsisJames S. Ashe (1947-2005) and Stylianos Chatzimanolis
Species of Allodinopsis are medium-sized (4.0-4.3 millimeters) deinopsine staphylinids; they are known only from the Osa Peninsula of Costa Rica and Chiriqui Province in Panama. Their habitat is not known; all specimens have been collected in flight intercept traps.
Adults of Allodinopsis are very similar to Metadeinopsis; they have similar overall body shape, most features of mouthparts, and the 5-5-5 tarsal segmentation. They can be distinguished from Metadeinopsis by the following characteristics:
- mandibles elongate, with a large apical and 4 subapical blade-like teeth;
- epipharyngeal region with numerous apically branched setae;
- adoral surface of first labial palpus without longitudinal row of large medially directed setae;
- terminal antennal article constricted into narrowly conical apex, but not distinctly papillate;
- distinctive shape of mentum;
- very strongly blade-like carina medially on the mesosternum;
- unusually elongate tarsal segment 1 in known species;
- distinctive shape of the pronotum;
- cuticular fringe on the apical margins of abdominal segments III-VI consisting of slender spinose processes;
- presence of a spinose cuticular fringe on apical margin of abdominal tergum VIII;
- distinctive female sternum IX with small papilliform process internally near lateral margin;
- presence of sclerotized spermathaeca.
