was not significantly different between the White River sites and CAB-0.8.
We made gross morphologic measurements of body length (rostral tip of the cement gland to the tip of the tail), interocular distance
(between the medial edges of the eyes), and body shape (presence of abnormal dorsal curvature).
Two of these were second-order spatial relations: the vertical mouth position and the interocular distance
. These were chosen because prior work showed that humans are highly sensitive to such displacements (Haig, 1984).
Length of head 1.16/1.15, preocular part 0.70/0.66, postocular part 0.38/0.34, width across eyes 0.68/0.71, interocular distance
--Body smaller (<6.0 mm); antennal segment I shorter or as long as interocular distance
; medial swelling on scutellum distinct, but less convex (Figs.

BL, body length; HW, head width; IOD, interocular distance
; PL, pronotum length; PW, pronotum width; FWL, forewing length; FWW, forewing width; HFL, hindfemora length; HTL, hindtibia length; OL, ovipositor length.
Of these, eight were significantly bigger in the males: the snout-vent length, the width, the length and the high of head, the interocular distance
, femur's length, tibio-fibula's length and the tail's length.
A conventional central hinge arrangement allows the interocular distance
to range from about 50 to 75 mm.
