Abstract

We present the first record and description of the gregarious behavior of the Neotropical harvestmen Serracutisoma proximum (Mello-Leitao 1922) and Serracutisoma spelaeum (Mello-Leitao 1933) (Opiliones: Gonyleptidae: Goniosomatinae) (DaSilva \& Gnaspini 2010). We followed and described the pattern of these aggregations over a period of 17 months in a cave in southeastern Brazil. Individuals of the two species aggregated with both conspecifics and heterospecifics during the non-reproductive season (i.e., from October to March, the cool and dry season). Aggregations contained up to 81 individuals, usually with a female-biased adult sex ratio. Multispecific aggregations were usually composed mainly of representatives of one of the two species, suggesting that although these species also aggregate with heterospecifics, there is a preference for aggregating with conspecifics. This study provides novel information on the social behavior of harvestmen, specifically regarding the composition of multispecific aggregations. (AU)
