Fig. 2From: High mitochondrial sequence divergence in synanthropic flea species (Insecta: Siphonaptera) from Europe and the MediterraneanMorphological comparison of Ctenocephalides felis felis females representing the most divergent haplotypes. Pictures (a) and (b) show the head and pronotum from clusters A and C, respectively. The yellow dashed line between the basis of the anterior and dorsal incrassations serves to highlight the more (a) or less (b) flattened upper front part of the head. c, d show the hind tibia from clusters A and C, respectively. The purple arrow indicates difference in chaetotaxy, which was, however, found only in one out of four specimensBack to article page
