Type material examined.

Holotype (male): "ECUADOR: Pastaza Province: "AGIP platform Villano B/ along transect 1 & 2/ 24.v.2008; leg. A.E.Z. Short/ small forest stream AS-08-08b" ( PUCE). Paratypes (1): ECUADOR: Same data as holotype (1, SEMC, DNA voucher SLE 1189).

Differential diagnosis.

Katasophistes superficialis  can be easily differentiated by its size (~4.5 mm), elongate oval shape, the shallow rows of enlarged systematic punctures along the elytra and its relatively long and slender maxillary palps.

Description.

Body length 4.5 mm, width 2.4 mm. Body elongate oval, weakly convex (Fig. 10 E, F). General coloration uniformly brown. Each elytron with five rows of shallow enlarged systematic punctures. Apex of fifth abdominal ventrite weakly emarginated. Aedeagus (Fig. 12E) with basal piece nearly 1.1-times the length of parameres; parameres at widest point, nearly 0.4-times greatest width of median lobe; apex of parameres rounded; apex of median lobe forming an acute angle.

Etymology.

Named in reference to the shallowness of the enlarged systematic punctures along the elytra, with the Latin word superficialis meaning shallow.

Distribution.

Ecuador (Pastaza). See Fig. 13.

Biology.

This species was collected in forested stream pools with abundant detritus in lowland rainforest. See Fig. 14E, F.
