This meant there was effectively no sudden widening at the ampulla to catch in her tibial spur notch, and her method for removal was relatively ineffective.
Pronotum with strong lateral and dorsal carinae, posterolateral angle strongly carinate; scutellum flat, in same plane as scutum in profile view; inner hind tibial spur pectinate, with 4 teeth (not including apex as tooth).
We analyzed this character in Apistobuthus, scoring a "loss" if the tibial spur was either absent or degenerated to a very small vestigial spur (< 20% the length of a fully developed spur).
One patient did not return to dance performance because of concurrent unrelated orthopaedic problems, but he resumed work as a dance teacher; he developed a recurrent anterior tibial spur that was successfully resected at a second arthroscopy nine years later.
However, we found that there is a strong correlation between the covariant SVL and the presence and size of the spur, suggesting that tibial spur length increases in relation to the tibia as Eurycea salamanders grow.
The tibial spur formula (0-2-2) suggests that it is E.
irrigatus, mention that the adults can be recognized by the frons without setae; antenna short, same length in both sexes, about 30 flagellomeres; antennal fossae separated by about width of pedicel; fore femur without clavate setae; ocular rim without setae; fore femoral sense hair as long as fore femur and mid femoral sense hair; mesonotum without blade-like setae; tibial spurs present; pretarsal claws large, longer than one-half length of distal tarsomere; pilula axillaris large; fore wing vein 2A runs in a fairly even curve toward 3A; posterior area of hind wing narrower than presectoral area, CuA bends to hind margin at or before origin of medial fork; anterior banksian line weakly developed; fore wing without dark brown stripe in mediocubital area.

With its final molt, the male develops elongated legs and tibial spurs to hold the female's fangs back when they mate face to face.
