Diagnosis
The female of S. confusus sp. nov. can be separated from that of all other species of this group by the following character combination: surface of scutum between coarse punctation with fine punctation ( Fig. 76C View Fig ); discs of T1–T3 finely and densely punctate (i = 1–2 d) ( Fig. 76E View Fig ); facial fovea about 4 times as long as wide ( Fig. 76B View Fig ). The male is characterized by surface of scutum between coarse punctation with fine punctation ( Fig. 77B View Fig ); facial fovea about 3 times as long as wide; flagella of antennae shorter than the compound eye ( Fig. 77A View Fig ).
Etymology
The unusual appearance of this species and the confusion caused by this with respect to its systematic placement within the genus Scrapter is reflected in its name.
