FIGURE 31 in Gyrodactylus jarocho sp. nov. and Gyrodactylus xalapensis sp. nov. (Platyhelminthes: Monogenea) from Mexican poeciliids (Teleostei: Cyprinodontiformes), with comments on the known gyrodactylid fauna infecting poeciliid fish
FIGURE 31. Principal components analysis plot (Factor1 vs Factor2) of Gyrodactylus bullatarudis Turnbull, 1956, Gyrodactylus cytophagus Paperna, 1968, Gyrodactylus poeciliae Harris & Cable, 2000, Gyrodactylys rasini Lucký, 1973 and Gyrodactylus xalapensis sp. nov. (13 ln-transformed variables; n = 29 specimens). The specimens of G. xalapensis sp. nov. (ellipse 1) are clearly separated from G. rasini (ellipse 2). Separation of the specimens is effected by the several hamulus variables acting along Factor1 (total length (HTL), shaft length (HSL), point length (HPL), aperture distance (HA), distal shaft width (HDSW) and the proximal shaft width (HPSW)) and by point curve angle of the hamulus (CosHPCA), the total length (MHTL) and shaft length (MHSL) of the marginal hook acting through Factor2. Plot codes: a. G. bullatarudis from Poecilia mexicana Steindachner; b. G. bullatarudis from Xiphophorus hellerii Heckel; d. G. xalapensis sp. nov. from Heterandria bimaculata Heckel; e. G. bullatarudis paratype from Poecilia sphenops Valenciennes; j. G. poeciliae from Poecilia caucana (Steindachner); l. G. cytophagus from Aplocheilichthys pumilus (Boulenger); m. G. rasini from X. hellerii.
FIGURE 30 in Gyrodactylus jarocho sp. nov. and Gyrodactylus xalapensis sp. nov. (Platyhelminthes: Monogenea) from Mexican poeciliids (Teleostei: Cyprinodontiformes), with comments on the known gyrodactylid fauna infecting poeciliid fish
FIGURE 30. Principal Components Analysis plot (Factor1 vs Factor2) of the 13 point-to-point measurements made on 45 gyrodactylids collected from a range of poeciliid hosts. Separation of the specimens is principally influenced by the hamulus total length (HTL), shaft length (HSL), point length (HPL) and aperture distance (HA) acting along Factor1 in a negative direction, and the inner (CosIHAA) and outer (CosHAA) hamulus angles acting along Factor1 in a positive direction. The total length (MHTL) and the shaft length (MHSL) of the marginal hook are key variables in the separation of specimens along Factor2. The raw ellipses highlight the specimens of Gyrodactylus xalapensis sp. nov. from Heterandria bimaculata Heckel (1), and Gyrodactylus jarocho sp. nov. from Xiphophorus hellerii Heckel (2).
