(!) Newportia (Tidops) Chamberlin, 1915

Figs 22–25

Synonyms. Kartops Archey, 1923 .

Type species. Tidops simus Chamberlin,1915 (by monotypy).

Diagnosis. Anterior margin of forcipular coxosternite with two short, blunt projections ( Fig. 20 ); forcipular tarsungula short, barely overlapping each other when adducted. LBS 7 without spiracles. Ultimate leg with tarsus 2 divided into 6–23 variably-distinct secondary articles, without claw-shaped pretarsus.

Number of species: 4.

Remarks. Treated as a genus in Edgecombe & Bonato (2011: 406), Chagas-Jr (2011: 63), Vahtera et al. (2013: 579) and Bonato et al. (2016). As a result of a molecular analysis Vahtera et al. (2013: 589) suggested this genus to be a subgenus of Newportia . Schileyko (2002) was the first to doubt the validity of the enigmatic genus Kartops Archey, 1923 when he wrote that (p. 5): “The same investigation allows also to regard the genus Kartops … to be a junior synonym of Tidops “. Edgecombe & Bonato (2011: 406) agreed with that, noting that Tidops possibly includes Kartops . The most recent morphological account on Tidops is that by Chagas-Jr (2011: 71), who synonymized Kartops with Tidops .
