Fig. 132. Ibotyporanga Mello-Leitão, 1944, male chromosome plates of I. naideae Mello-Leitão (A, C–I) and Ibotyporanga sp. (B). A. Spermatogonial metaphase, including Y chromosome; note metacentric morphology and slight positive heteropycnosis of this element. B. Spermatogonial metaphase (2n = 30), including Y microchromosome. C. Premeiotic interphase; note a heteropycnotic body formed by sex chromosomes and rod-shaped element exhibiting weak heteropycnosis. D–E. Diffuse stage; note cluster comprising four heteropycnotic sex chromosomes (D) or sex chromosome body (E) and a heteropycnotic bivalent. F. Late prophase I consisting of 13 bivalents and sex chromosomes, which show considerable decondensation. One bivalent is positively heteropycnotic except for chiasma region. G. Sex chromosome tetravalent from metaphase I (separated by dashed line from bivalents); note scheme of sex chromosome pairing (blue – X chromosomes, orange – Y chromosome). H. Two sister metaphases II separated by dashed line. Left plate contains 16 chromosomes, right plate 14 chromosomes including small Y chromosome. Note predominance of biarmed chromosomes. I. Metaphase II containing 14 chromosomes; note small heteropycnotic Y chromosome. Arrows without letters point at sex chromosome body/cluster; arrowheads point at heteropycnotic bivalent/element. Abbreviations: X = X chromosome; Y = Y chromosome. Scale lines: A–F, H–I = 10 µm; G = 5 µm.

Records of I. naideae Mello-Leitão, 1944 were excluded from the distribution modeling, but are plotted in the map. Numbered sites represent areas with higher ROR, namely: (1) Caatinga province; (2) Western Ecuador and Ecuadorian provinces; and (3) Venezuelan province. Live spider: I. sertao Huber sp. nov., female with eggsac from Brazil, Cocal.

Principal component analysis of the environmental conditions for species of Ibotyporanga Mello-Leitão, 1944 from Brazil (red circles), Colombia (green triangles) and Venezuela (blue squares). The ellipses encompass the values within a 95% confidence interval of a multivariate t-distribution (absent for Venezuela owing to the small number of records). Records of I. naideae Mello-Leitão, 1944 were excluded from this analysis.
