Distribution of longitudinal striae on S2: present throughout. Macrosculpture of S2: longitudinally striate. Form of S2 felt field: anterior excavation of coarse rugae. Marginal depression on S3: present. Marginal depressions on S4: present. Marginal depression on S5: present.

Diagnosis.

Paridris mnestros uniquely has the felt field of S2 as an anteriorly located pit of coarse rugae. The constriction of the apex of T6 into a rather sharp point is also not found in any other species of Paridris . Lastly, this is the only species outside of the Paridris nephta species group to exhibit bright coloration of the body and a banded metasoma.

Etymology.

The Greek word for marriage “mnestros” is given to this species to commemorate the wedding of Ryan St. Clair to Grace Wong, and because this species combines morphological structures commonly found in Paridris (i.e. apical constriction of T6, posteriorly directed spine on horn of T1) with the coloration, mesoscutal surface sculpture, and very long setation found in the Paridris nephta species group.
