The whole body of this scorpion is yellowish and only its hands (end of pedipalp
segment) are dark brown.
This species is characterized by the presence of two setae that are linearly arranged along the propeltidium (Figure 1a), a 'spur' pedipalp
in a medial trochanter (Figure 1b), and internal female genitalia (Tourinho and Kury, 1999).

While on the female's ventral side, the male drummed with his pedipalps
on and near the female's genital openings (epigynum), and finally inserted a pedipalp
into the female genital opening.
The egg at the 35th hour of incubation showed the development of embryonic metameres which were anteriorely formed an acron, primary buds for pedipalp
and chelicerae and also first pair of legs.
The evidence for a terminal molt include (1) field measurement of 288 adults in Pleasant Bay indicating adults of several age groups have similar size distributions (Shuster 1955), (2) the male pedipalp
is transformed at maturity from chelate form to a swollen hook useful for grasping females during amplexus, (3) presence of internal chitinous fibers (trabeculae) in male and female adults, which could interfere with ecdysis (Shuster & Sekiguchi 2003), (4) the observation that slipper shells (Crepidula fornicata) up to 8 y old have been found attached to adult carapaces indicating that molting had not occurred for at least the slipper shell's lifespan (Botton & Ropes 1988a, Grady et al.
The male spider grows to only about one-hundredth the size of a female, yet one pedipalp
accounts for some 10 percent of his body mass.

2) Does the presence of the pedipalp
(an adult sexual characteristic) really indicate male sexual maturity?
