Davies), Methuen and Co.]

abdominal segments 8 and 9. In males the appendages of the ninth abdominal segment fuse to form a median penis.

Internally Microcoryphia exhibit features that might be expected of primitive insects. They have 12-20 Malpighian tubules, a nervous system that includes paired longitudinal connectives, 3 thoracic and 8 abdominal ganglia, 9 pairs of spiracles and tracheae that do not anastomose with those of adjacent segments, and a primitive reproductive system. In females there are typically seven or eight panoistic ovarioles on each side of the body, and in some species these are arranged in a more or less segmental manner. Females lack a spermatheca. In males each testis comprises three or four follicles, and the vas deferens on each side is double, the two channels being connected by several transverse tubes.
