Morphometric study of Gliricola quadrisetosa Ewing 1924, recovered in Galea spixii Wagler, 1831

The morphometric study on lice affecting Galea spixii helps in understanding the taxonomy of this Phithraptera. The study aimed to perform morphometry of Gliricola quadrisetosa specimens recovered in G. spixii. Analyses were performed using light optical microscope. Data were presented as simple average and standard deviation. Males and females showed an average length of body of 98,01 ± 2,43 and 117,97 ± 4,75 µm; from the underside of the head 16,42 ± 3,41 and 18,43 ± 2,61 µm; prothorax 12,43 ± 0,91 and 13,79 ± 1,13 µm and pterothorax 13,57 ± 1,07 and 14,88 ± 1,84 µm, respectively. The male genitalia lodged in their basal plate showed length of its external and internal lateral margin of 28,86± 1,29 and 21,88 ± 1,91 µm; external internal branch of 2,94 ± 0,38 and 7, 25 ± 0,72 µm. In the female genitalia, the length of the upper and lower portions were, respectively, 25,35 ±2,32 and 28,18 ± 2,86 µm. The 11 bristles had an average length of 2,99±0,17 µm. The measurements will help to standardize the taxonomy of Gliricola quadrisetosa recovered in Galea spixii.
