Paragus (Serratoparagus) azureus scrupeus Stuckenberg 1954
Subgenus Serratoparagus:
The Paragus serratus-group was defined by Stuckenberg (1954), and was erected as the subgenus Paragus (Serratoparagus) by Vujic et al. (2008).
Diagnosis: Scutellum with conspicuous teeth (minimum about double length of diameter) on posterior margin. Eye with vertical alternate vittae (bands) of pile reflecting light differently; in dorsolateral view with two dark and three more distinct, white, dorso-ventral stripes.
Paragus (Serratoparagus) azureus scrupeus:
This subspecies differs from the typical form in having well developed sculpturation on the abdomen.
Females have a spot of pollen on each side of the anterior ocellus.
Thorax dull black in the male, with cyanescent and violaceous reflections in the female. Mesonotal stripes conspicuous and white, complete in the male, almost complete in the female.
Scutellum with 12 subequal teeth, moderately long and each tipped with dark brown.
Wings with pale stigma, clear yellow, and veins light brown; subcosta and apical part of first longitudinal vein yellowish-brown.
Abdomen broad; sides flattened and triangular in crosssection, differing in this respect from P. capricorni and pusillus which have distinctly rounded sides. Third and fourth segments distinctly carinate. Sculpturation strongly developed on all segments. Abdomen brown, translucent, a little darker and reddish in places. Sides of second segment narrowly fusco-piceous, this dark colour continuing onto
apical corners of first segment. Vittae white and distinct.
