Description.
Length 4.3 mm, width 0.9 mm, W/L ratio 21%. Color a dull pink in life (
Fig. 1
).
Head uniformly and densely setose, except for the clypeus. Frons with small protuberances just above the antennal sockets. Antennae clavate, C-shaped. Antennomere lengths 1, 2, 7<4<3<5=6.
Body H + 20 segments in both males and females. Collum broad and flabellate, dorsally obscuring head in its entirety. Collum margins smooth, unscalloped, though divided radially into 6+6 subequal sectors by 11 radii; finely granulate, though with no notable tubercules as is common in
Pyrgodesmidae
(
Fig. 2
). Metatergites microgranulate with low, broad bosses, entirely glabrous (
Fig. 2
). Postcollum paranota with 3 lobes (segments 2–4, 6, 8, 11, 14) or 4 lobes (segments 5, 7, 9, 10, 12, 13, 15–18), without porosteles. Pore formula normal, ozopores flush, open dorsolaterally between the third and fourth lobes (
Fig. 3
). Epiproct exposed dorsally, subconical. Apicodorsal trichostele absent from both ultimate and penultimate tibiae.
Gonopods quadripartite (
Fig. 4
). Endomere, solenomere, and velum subequal in length, exomere a short, curved process. Endomere ensiform, ectally serrate. Solenomere slender, apically plumose. Velum tall, flattened, and loosely wrapped around the solenomere, obscuring its apex from view in most aspects. Exomere apically dentate and curved mesad.
In situ
, gonopods nest together so that one velum cups the other (
Fig. 5
). Coxae globose and finely spiculate, with scattered setae.
