Table V. Comparison by Mann–Whitney U test of first three regression factor scores (RFS) generated by principal component analysis based on 27 measurements between a sample of four adult specimens of Chaparana aenea (Smith, 1922) (see Table II) and six adult specimens of Chaparana unculuanus (Liu, Hu and Yang, 1960) (see Table IV).

Regression factor	Chaparana aenea	Chaparana unculuanus
For each criterion of comparison, minimum and maximum values of RFS given for samples are those obtained by PCA for the first (RFS 1), second (RFS 2) and third (RFS 3) regression factor scores. Significance levels: ns, not significant, P.0.05; * P ǩ0.05.
