- Abstract
Ficus benjamina (Moracaeae subfamily Urostigma, section Conosycea) grows naturally in tropical Asia and in Australia in the north of the Northern Territory and the Cairns region of Queensland. It is widely grown as an ornamental in more temperate regions of Australia. Schistonchus benjamhza sp. n. is described from sycones of F. benjamina in Brisbane, and is differentiated from other species of Schistonchus by a combination of morphological characters including having the excretory pore opening near the head, a short post-vulval uterine sac, rose thorn-shaped spicule, lightly sclerotised stylet and spicule, and three pairs of subventral papillae on the tail (one adcloacal, one at mid-tail length and one near the tail tip); and apparent biogeographical range. Phylogenetic analyses based on D3 sequences from collections from both northern and southern Queensland suggest that S. benjamina sp. n. is a species complex, but specimens from the different locations cannot be separated on morphological or morphometric data. Schistonchus benjamina sp. n. is closest to S. microcarpus from F. microcarpa (Urostigma, section Urostigma) in China.
