Table 2.

Assignation errors using landmark collection from the wings of two Glossina species

Species Distances One user Two users
Glossina p. palpalis Procrustes 2/44 (5%) 2/44 (5%)
Mahalanobis 1/44 (2%) 8/44 (18%)
Glossina f. fuscipes Procrustes 5/44 (11%) 10/44 (23%)
Mahalanobis 1/44 (2%) 14/44 (32%)

Total errors Procrustes 7/88 (8%) 12/88 (14%)
Mahalanobis 2/88 (2%) 22/88 (25%)

Assignation errors according to the "one user" and "two users" procedures, and according to Procrustes and Mahalanobis distances. "One user" means that the same user digitized both the reference and the external specimens. "Two users" means that reference and external individuals were digitized by two different persons. Absolute values are the number of wrong species attributions out of the total of "unknown" specimens examined. For instance, "2/44" ( first row) means that 2 of the 44 external individuals known to be G. p. palpalis were wrongly assigned to G. f. fuscipes, according to the Procrustes distances.
