M. armillata and P. dikowi represent species with unusual histoblast nest patterns. Both possess the appendage, but nest morphology is not sexually dimorphic. P. dikowi females present the male phenotype having significantly enlarged nests in both sexes. M. armillata males present the female phenotype with no increase in nest size. M. armillata possesses diminished appendages and little sternite modification, indicating that small appendages do not require an increase in histoblast nest size. Refer to Table 3 for the number of individuals sampled for each species
