Diagnosis.
Phrynarachne lancea
males can be easily distinguished from other species by the wide, spear-shaped RTA. Females of
P. lancea
are similar to
P. mammillata
in having an M-shaped median plate and kidney-shaped spermathecae. However,
P. lancea
can be distinguished by the length to width ratio of the median plate (7:1 in
P. lancea
vs 4:1 in
P. mammillata
), the straight posterior edge of the median plate (vs procurved in
P. mammillata
), the posterior edge of the spermathecae shorter than the anterior edge (vs of equal length in
P. mammillata
), and the longitudinal fertilization ducts (vs transverse in
P. mammillata
).
