Eye dull and dark with a vestigial nictitating membrane*. 2. Barbels long and fleshy. 3. Humerus and femur of subequallength*. 4. Inguinal and axillary buttresses of subequal size*. 5. Precentral [nuchal] scute always present. 6. Tail distinctive (all sexes and ages) in having a large precloacal portion*, a longitudinal, slitlike cloacal orifice*, and in being laterally compressed*. 7. Distal caudal vertebrae much higher than long and bearing distinct haemal arches*. 8. Length of tail in adult males more than half length of carapace and significantly longer than combined length of head and neck*.
|Etymology||genus name from Latin “eludo” to escape, to escape notice of; ergo, a contrived word of male gender connoting a frustratingly elusive thing, alluding to the cryptic provenance of this organism during the many years we knew it existed; macrurus: Gr. makros, long, + Gr. oura, tail; referring to the long and distinctively shaped tail.|
