Maximum diameters are given for nurse cells. Abbreviations and symbols: “vitell.d.” vitellogenic doublets, “o + d” oogonia and oocyte doublets
in the same ovary (“+0” indicates the presence of an embryo, derived from the leading oocyte, in the brood chamber), “•” the presence of yolk
granules in the nurse cell, “×” two longest perpendicular diameters, “−” diameter range; numbers in circles “3” and “4” are given to the species
with corresponding reproductive pattern (the rest of the species have reproductive pattern II)
