New records of Acropsopilio neozealandiae (Forster), and remarks on the sexual status of the species (Arachnida: Opiliones: Caddidae)

Abstract

Acropsopilio neozealandiae (Forster) is a tiny endemic New Zealand harvestman previously reported from seven localities. Extensive pitfall collecting in the southern half of the North Island and northern quarter of the South Island produced 70 individuals, from 42 locations, documenting its local distribution. The collection method is described fully, to assist future work. All specimens that could be confidently identified were female, so it seems likely that A. neozealandiae reproduces, at least within our study areas, by parthenogenesis—as do at least two of its congeners. Our specimens showed no obvious morphological variation over their range. © The Royal Society of New Zealand 2007.
