Eschatoporini Blaisdell, 1906: 78 [stem: Eschatopori-]. Type genus: Eschatoporis Blaisdell, 1906 (type species: Eschatoporis nunenmacheri Blaisdell, 1906, by monotypy). Comment: incorrect original stem formation, not in prevailing usage (See Bouchard et al. 2011: 398).

Remarks.

The Eschatoporiini are very similar to the Adeliini and mostly fit within the description and range of the characters as described by Matthews (1998: 701). However, the Eschatoporiini differ from the Adeliini in some key characteristics. The following characters/character states will separate the Eschatoporiini from the Adeliini : Head with basal membrane of labrum exposed, eyeless, but occasionally with a remnant eye scar; maxillary palps with apical segment oblique, not strongly triangular; tentorial bridge present, not arched, sides of tentorium broad, subparallel, continuing to submentum as low ridges; mesepisternum and mesosternum greatly expanded ante riorly forming a neck-like process between thorax and abdomen; scutellum very large; sternal defensive glands absent on all sternites and tergal cuticular sacs present between tergites 7 and 8.
