Diagnosis. A species of Aphilodon  with: around 53–59 leg-bearing segments; known body length in adults 11–19 mm; cephalic plate length/width ratio 1.1–1.2; antenna ca. 2 times as long as cephalic plate; pectinate lamella of mandible with straight denticles; coxosternite of second maxillae not distinctly shorter in middle part; forcipular pretergite exposed; telopodite of second maxillae with article 3 shorter than article 2 and with 2 subapical setae and a short sensillum between; forcipule with lateral margin posteriorly straight; tarsungulum ca. 0.8–0.9 times as long as trochanteroprefemur+femur; forcipule with 3+1 denticles; distal denticle of trochanteroprefemur, denticle of femur and denticle of tibia relatively large and denticle of tarsungulum relatively small; distal denticle of trochanteroprefemur and denticle of femur separate; all pleurites conspicuous; each coxopleuron with 6–8 coxal pores in adults; ultimate presternite entire or apparently divided in middle part; metasternite of ultimate leg-bearing segment length/width ratio ca. 0.7; ultimate legs ca. 1.7–1.8 times as long as penultimate legs, with tarsus 1 1.1–1.2 times as long as tibia.

A. angustatus  differs from all other species of Aphilodon  by having: around 53–59 leg-bearing segments; body length less than 25 mm; distal denticle of trochanteroprefemur, denticle of femur and denticle of tibia relatively large and denticle of tarsungulum being relatively small ( Fig. 18CView FIGURE 18); less than 10 coxal pores on each coxopleuron in adults.

Recorded specimens:> 25, including 17 ♀ and 5 ♂, from 10 localities.

Distribution. Argentina—Misiones: Corrientes, San Pedro ( Silvestri 1909b). Brazil—Mato Grosso: Corumbá, Urucum ( Silvestri 1909b); Poconé, Pirizal ( Pereira et al. 2007); Nossa Senhora do Livramento ( Battirola et al. 2017). Brazil—São Paulo: Bananal (new record); Cotia, Caucaia do Alto (new record); Iporanga, Parque Estadual do Alto do Ribeira (new record); “zona araraquarense” ( Bücherl 1942a). Brazil—Paraná: Sangés (new record). Paraguay—Paraguarì ( Silvestri 1909b).

Known variation. Sternite of the ultimate leg-bearing segment: shorter in middle in all specimens from Parque Estadual do Alto do Ribeira (PETAR) (N= 3♀, 2♂).
