Figures 2-5 in Chromosomal and genetic characterization of four Caribbean Prioninae (Coleoptera: Cerambycidae) species with notes on biogeography

Figures 2-5. Karyotypes of Solenoptera species. 2) Giemsa stained male karyotype of S. canaliculata. The arrows on chromosome 4 indicate an elongated region, which is the only region stained by C-banding. Bar = 10 μm, as in other figures. 3) Karyotype of a spermatocyte I at pachynema of S. canaliculata, after Giemsa (left) and silver (right) stainings. The NOR on bivalent 4 looks elongated, and is surrounded by nucleoli after silver staining. 4) Giemsa stained XYY karyotype of S. quadrilineata. Chromosome 4 is elongated at the same position as in S. canaliculata (arrow), which indicates the position of the NOR. 5) Giemsa stained metaphase I of the XYY male of S. quadrilineata exhibiting a parachute sex trivalent. Arrows point out the two Ys. The accidental presence of two Ys in male beetles was estimated to about 1 per cent (Dutrillaux and Dutrillaux 2011). Bars = 10μm.
