Table 4 Morphometric variables (range and mean values in millimeters) of Ornithodoros rietcorreai larvae from Paraíba (♂PB × ♀PB homologous cross; n = 10); Piauí (♂PI × ♀PI homologous cross; n = 10); Paraíba × Piauí (♂PB × ♀PI heterologous cross; n = 10); and Piauí × Paraíba (♂PI × ♀PB heterologous cross; n = 7) utilized in the principal components analysis (PCA)

From: A new argasid tick species (Acari: Argasidae) associated with the rock cavy, Kerodon rupestris Wied-Neuwied (Rodentia: Caviidae), in a semiarid region of Brazil
