Mr Blackwall refers me for striking sexual differences in colour & number to Aug. Vinson Aranéides des Iles de la Réunion, Maurice &c
Pl. V. 1 & 2 - Pl. VI. fig 1. & 2
-> Epeira nigra wonderful difference in size: ♀ black with legs banded with red - ♂ wonderfully small & testaceous.
Auguste Vinson. 1863. Aranéides des îles de la Réunion, Maurice et Madagascar. Paris. See CUL-DAR84.1.168-169. Darwin cited this in Descent 1: 338, n14: "Aug. Vinson ('Aranéides des Iles de la Réunion,' pl. vi. figs. 1 and 2) gives a good instance of the small size of the male in Epeira nigra. In this species, as I may add, the male is testaceous and the female black with legs banded with red. Other even more striking cases of inequality in size between the sexes have been recorded ('Quarterly Journal of Science,' 1868, July, p. 429); but I have not seen the original accounts."
