This is mounted ventral side uppermost, the head is crushed and distorted, and the body contains a large quantity of opaque white pigment such that most details of the integument are not visible. Antennal segment III is shorter on this specimen than in any other available specimen of this genus, apart from the holotype of barretti . The body length is about 3100 microns; head length 450; tube length 670; antennal segments III–IV length 180, 110. The ratio of tube to head is thus 1.5. Without a sample from one population exhibiting a range of body sizes the identity of caudatus will remain in doubt.
