of slide-mounted female, with diagnostic characters; ao-anal opening, pl-pygidial lobe.
websteri exhibit a high degree of morphological plasticity in the palp pigmentation pattern, the shape of the anterior edge of the prostomium, the shape of the major spines on chaetiger 5, and the shape of the pygidium
with anus surrounded by several terminal lobes and with two large ventral cirri (Figs.
Then, the male held the female with the pairs of legs, and positioned the posterior part of its body next to the female pygidium
and inserted the aedeagus to begin copulation.

small, rounded, with one pair of very short ventral knobs .
Adult specimen length was measured from the tip of the clypeal horns to the apex of the pygidium
Para la confirmacion de la especie se tomo en cuenta el pygidium
(Figura 3c) el cual presento el dorso esclerotizado en un patron reticulado, con un par de lobulos medios redondeados bien separados y un par de setas marginales entre ellos.
The correlations analysis of Spearman's shows that rainfall acts negatively on reproductive activity (P = 0,0132, Ratio= -0,68) by preventing the theft of the adult males on lemon-tree, (P = 0,060, Ratio= -0,55) for the sliding of the females towards the party inferior of the buckler, to display their pygidium
to the coupling on the orange-tree.
The exposed pygidium
is black, having a central longitudinal white streak.
