Table 5 Correlation coefficients between head and wing variation

From: Chagas vectors Panstrongylus chinai (Del Ponte, 1929) and Panstrongylus howardi (Neiva, 1911): chromatic forms or true species?

  1. Notes: For size correlation coefficients (r), P-value was computed according to the Studentʼs t-test. For shape correlation coefficients (Rv), which are here the Escoufier’s coefficient (see Methods), P-values are the proportion of pseudo-coefficients equal or larger than the observed coefficient after non-parametric tests (1000 runs)
