Figure 32

EGG DIMENSIONS: Length 1.5, 1.6 mm long; maximum diameter 0.35, 0.4 mm (n = 2). Shape (fig. 32) elongate, slightly curved; broadly round at front end, more narrowly rounded at rear. Color creamy white, semitransparent, with smooth but not shiny chorion. Micropyle not visible with stereomicroscope while submerged in Kahle’s solution, but faintly visible after critical-point drying before coating as a circular, somewhat shiny area, on the anterior end; SEM examination failed because of poor preservation.
