Pseudosmittia trilobata

Author: (Edwards, 1929)

Exuviae 1.8-1.9mm long (n=3).
Cephalothorax: Thoracic horn absent. Median antepronotal setae 1,2: 13-20; 20-30µm long; dorsocentral setae 1-4: 13-18; 13-15; 20; 10-40µm long (n=3).
Abdomen: Tergite I armed with small points antero-laterally. Tergites II-VIII, apart from small bare patches, covered with more or less evenly sized points. Postero-median points of tergites obviously smaller than those in front and behind, resulting in a transversely striped appearance (070a.jpg). Armament of tergite VIII at least considerably reduced in front of the posterior transverse point band; in the majority of specimens there is a transverse point-free band across the third quarter of the tergite. Conjunctival point bands present dorsally on II/III-V/VI, ventrally (IV/V)V/VI-VII/VIII (male and female).
Anal segment: Male anal segment with a median longitudinal ridge bearing two or three rows of strong points; male genital sheaths covered with small points over most of their ventral surface. Anal lobes without fringe.
