Subfamily Newportiinae Pocock, 1896

Synonyms. Ectonocryptopinae Shelley & Mercurio, 2005

Diagnosis. Antenna with normal trichoid sensilla, lacking collared sensilla ( Fig. 23 ). Anterior margin of forcipular coxosternite without well-developed tooth plates, either smooth ( Figs 17 , 21 ) or with projections in Newportia (Tidops) Chamberlin, 1915 ( Fig. 22 ). Forcipular trochantero-prefemur without well-developed process (with pointed minute tubercle in some species); tarsungula of variable length ( Figs 21, 22 ). LBS 7 with (in most species) or without spiracles. Coxopleuron with conical process of variable length. Ultimate legs “lasso-shaped” sensu Schileyko (2009) (i.e. their tarsus 2 elongated and divided into numerous (4 to 40) variably-distinct secondary articles thus forming a kind of functional antenna, Figs 19 , 20 ) or of “ectono-type” (see Schileyko 2009), i.e. somewhat shortened and swollen, subclavate, with inflated distal podomeres ( Figs 14, 15 ). Ultimate prefemur with 3–6 large spinous processes, femur with a few (0–3) smaller spinous processes. Ultimate pretarsus absent in most taxa of both genus-group and species (except for 3 or 4 species of Newportia (Newportides) Chamberlin, 1912 , figs 29, 47 in Chagas-Jr 2018).

Number of subtaxa. 1 genus, 5 subgenera (“Ca 60 species in two genera” in Edgecombe & Bonato 2011: 405).

Sexual dimorphism. Unknown.

Range. Neotropics: from Central Mexico to Paraguay, including Cocos Island and Caribbean Islands.

Remarks. Treated as a subfamily in Edgecombe & Bonato (2011: 405), Vahtera et al. (2012a: 9, 2013: 578). As a result of work of Vahtera et al. (2013) this subfamily became monotypic because the former genera Tidops , Ectonocryptops Crabill, 1977 and Ectonocryptoides should belong to a single genus Newportia Gervais, 1847 (see below).
