Patch of dense fine setae on anterolateral T1: absent. Form of T2 sulcus: transverse furrow. Posterior margin of transverse sulcus on T2: straight. Carina along posterior margin of transverse sulcus on T2 in female: present. Sublateral tergal carina on T2: absent. Microsculpture on T2: absent. Macrosculpture of T2 in female: longitudinally striate. Microsculpture on T3: absent. Macrosculpture of medial T3 in female: weakly longitudinally striate. Macrosculpture of lateral T3 in female: longitudinally striate. Macrosculpture of female T5: absent. Microscupture on female T6: present throughout. Constriction of apical T6 in female: present. Macrosculpture of S1: rugose. Setation of S1: absent. Distribution of longitudinal striae on S2: present throughout. Macrosculpture of S2: longitudinally striate. Form of S2 felt field: lateral row or patch of setigerous punctures. Marginal depression on S3: absent. Marginal depressions on S4: absent. Marginal depression on S5: absent.


In Paridris bispinosa  , the metascutellum is distinctly bispinose and T6 is sharply constricted in its apical half, separating it from all but two African species, Paridris anikulapo  and Paridris trispinosa  . The females of Paridris bispinosa  have the notaulus present as a single fovea on the posterior margin of the mesoscutum and in females of Paridris anikulapo  the notaulus extends to the anterior mesoscutum. In the specimen of Paridris bispinosa  examined here, the gena is coarsely sculptured throughout and in Paridris anikulapo  the gena along the posterior margin of the eye is smooth and shining. Paridris trispinosa  may be separated from Paridris bispinosa  by the presence of a posteriorly directed spine on the horn of T1.

Material examined.

Other material: (1 female) GABON: 1 female, OSUC 265181 (CNCI).


We did not examine any males of Paridris bispinosa  in this revision, but we speculate that they will have an abbreviate notaulus, as in the females of this species, and that this will enable separation from males of Paridris trispinosa  .
