Evidence for Gustatorial Courtship in a Haplogyne Spider (Hedypsilus Culicinus: Pholcidae: Araneae)

Evidence for Gustatorial Courtship in a Haplogyne Spider (Hedypsilus Culicinus: Pholcidae: Araneae) EVIDENCE FOR GUSTATORIAL COURTSHIP IN A HAPLOGYNE SPIDER (HEDYPSILUS CULICINUS: PHOLCIDAE: ARANEAE) by BERNHARD A. HUBER (Escuela de Biología, Universidad de Costa Rica, Ciudad Universitaria, Costa Rica) ABSTRACT Gustatorial courtship, which is so far only known from two entelegyne families among spiders, is for the first time documented in a haplogyne spider, Hedypsilus culicinus Simon, 1893 (Pholcidae). The convergence to entelegynes is explained by (1) comparable mating position, and (2) body proportions. KEY WORDS: gustatorial courtship, sexual selection, Pholcidae, Hedypsilus culicinus. Gustatorial courtship, in which secretions from the male are transferred to the female's mouth and ingested during courtship and/or copulation is known in a variety of insects (e.g., THORNHILL & ALCOCK, 1983), opilion- ids (e.g., MARTENS, 1968) and erigonine (e.g., SCHAIBLE et al., 1986) and theridiid spiders (VOLLRATH, 1977) (for additional references see SCHAIBLE et al., 1986). In most cases a double function has been assumed: (1) the correct relative positioning of the sexual partners and maintenance of this position during copulation, and (2) the release of female behaviour or phys- iological responses that favor the male's chance of siring her offspring.
