Genus
Trogolaphysa Mills, 1938 sensu Thibaud and Najt (1988[1989])
Diagnosis.
Paronellidae
with finely denticulate scales covering dorsum of head and body, and ventral face of furcula; Ant. 4 sometimes annulated, never subdivided in two; labial seta L2 normal, not reduced; eyes 0-8; EOS present; Abd. 2-4 with 2, 3, 3 bothriothricha; manubrium without spines, dens with 1-2 rows of spines; mucro short, with 3-5 more or less evenly spaced teeth.
Remarks.
As currently circumscribed (
Thibaud and Najt 1988[1989]
), the absence of a subdivision on Ant. 4 in
Trogolpahysa
is the only character that distinguishes this genus from
Troglopedetes
.
It is not known if the type species of the genus,
Trogolaphysa maya
Mills, 1938, has EOS, but the presence of this structure in all species discussed below, including the two troglomorphic forms, suggests it is likely also present in that species.
