Thalkethops Crabill, 1960

Fig. 12

Type species. Thalkethops grallatrix Crabill, 1960 (by monotypy).

Diagnosis. Sternites without lateral margination as well as both median and transverse sutures but with “a shallow midlongitudinal and rather broad sulcus” according to the original description.

Number of species. 1.

Remarks. Treated as a genus in Edgecombe & Bonato (2011: 405), Bonato et al. (2016), Lewis (2016b: 26). In his short and undetailed account on Kethopinae, Shelley (2002: 78) reasonably mentioned that “There is very little difference between Thalkethops and Kethops, and they may have to merged when more material of both is available”, noting (p. 79) 6 other (in addition to the holotype) available specimens from six “new localities” (all in New Mexico) and mentioning that “No observable variation is evident”.
