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.

25 mm
; distal denticle of trochanteroprefemur, denticle of femur and denticle of tibia relatively large and denticle of tarsungulum being relatively small (
Fig. 18C
); less than 10 coxal pores on each coxopleuron in adults.
