FIGURE 4. Sternite 7 in A review of morphological characters for the identification of three common European species of Sarcophaga s. str. (Diptera: Sarcophagidae), with an emphasis on female terminalia
FIGURE 4. Sternite 7 (ST7) length to width ratio of Sarcophaga (s. str.) females. Our analysis shows that this morphological character can be used reliably to separate S. subvicina from S. carnaria and S. variegata in most cases (p <0.0001; indicated by asterisks). However, the ST7 length/width ratio cannot be used to distinguish between S. carnaria and S. variegata (p = 0.242; indicated by ns). Box plots show median and first and third quartiles; dots represent extreme outliers. The number (n) of analysed female specimens is indicated above the name of each species.
