Fig. 35 in Revision of the South American Ninetinae genus Guaranita (Araneae, Pholcidae)

Fig. 35. Karyology of Guaranita goloboffi Huber, 2000; males from Chumbicha (A, C) and Cabra Corral (B, D–E). A. Premeiotic interphase. Note positively heteropycnotic X chromosome on the periphery of the nucleus. B. Late diffuse stage. Plate consists of five bivalents and peripheral X univalent, which exhibits positive heteropycnosis. C. Two fused sister prophases of the second meiotic division (2n = 11). X chromosome does not differ by condensation pattern or behavior from the other chromosomes. D. Metaphase I composed of five bivalents and X chromosome univalent, detection of NORs by FISH. Particular bivalents separated by dashed line. Centromeric regions of chromosomes forming bivalents exhibit a bright fluorescence. Note two NOR-bearing bivalents (shafted arrows). Another NOR is possibly placed in the middle of an X chromosome arm (empty arrowhead). E. Karyotype, based on mitotic metaphase. Note five metacentric chromosome pairs and a large metacentric X chromosome. Scale bars = 10 µm.
