Photomicrographs of the female reproductive system of Megamelus scutellaris showing a) distal portion of the ovary showing the distal lateral oviduct (lop), common oviduct (co), bursa copulatrix (b), and spermatheca/spermathecal gland (spt and sptg, respectively), and b) close-up of ovariole morphology (b) showing the anterior lateral oviduct (loa), germarium (g), vitellarium (v), and terminal filament (tf).
a) N1--Note the lack of differentiation in the vitellarium (v) and large size of the germarium (g) in comparison to the vitellarium.
The germarium presumably continued to produce eggs that underwent some development in the vitellarium before resorption, as the maximum follicle size did not decrease with time.
Germarium oval, 164-495 (365) in diameter, pretesticular; short uterus; vagina long, with distal papilliform structure (Fig.
40 mm), greatest width 221-239 (230) to germarium level.
