Diagnostic Features.
Closely resembles
Tetragnatha laochenga
Barrion, Barrion-Dupo & Heong
,
new species
but differs from the latter in the following aspects, (
1
) presence of a red longitudinal band on the anterior and transverse bands on posterior ends of abdomen, (
2
) reddish and elevated cardiac area, (
3
) cheliceral dentation, (
4
) eye dimensions and separations, (
5
) position and shape of the epigynal fold, and (
6
) leg length and spination particularly in tibia I.
Etymology.
Derived from the combination of the unique red ("pula) longitudinal band ("banda") in the abdominal dorsum in Tagalog.
