JACOBI, M.A. 2016. On the two forms of Poecilotheria (Araneae: Theraphosidae: Selenocosmiinae) considered P. subfusca in arachnoculture and their proper nomenclature with a taxonomic overview and distribution map of tiger spider species in Sri Lanka. Journal of the British Tarantula Society 31(3): 22-37.
ABSTRACT - The Poecilotheria tiger spider from the Central Highlands of Sri Lanka currently regarded as P. subfusca is argued to be two distinct species from two isolated and completely different habitats. My article discusses the warm highland forests (ca. 600m elevation) surrounding Kandy, and how the type specimens of P. subfusca are from that region, and contrasts that to the cool alpine forests near Nuwara Eliya (ca. 2000m elevation) where a smaller, much darker form lives. The former is often referred to in arachnoculture as P. sp. "lowland" and thought of as the "new species", but this is the spider described by Pocock, 1895 as P. subfusca . It is the 'P. sp. "highland"' that is deserving of description as a new species.
SMITH, A.M. & JACOBI, M.A. 2015. Revision of the genus Phormingochilus (Araneae, Theraphosidae, Ornithoctoninae) with the description of three new species from Sulawesi and Sarawak and notes on the placement of the genera Cyriopagopus, Lampropelma and Omothymus. Journal of the British Tarantula Society 30(3): 25-48.
ABSTRACT - This project began as the description of a new species of Phormingochilus from the Kelabit highlands of extreme northeastern Sarawak (Borneo). This spider is P. pennellhewletti, honoring collectors Mark
Pennell & Dean Hewlett, and was dedicated to their dear friend and guide Jaman. But publishing this new species required comparing type material and revising related genera whilst describing a total of three new species of Phormingochilus. One of these was P. carpenteri, which is the hobby's "Cyriopagopus sp. Sulawesi black". Perhaps the biggest and most controversial change this paper made was revising the southeast Asian earth tigers of the genus Haplopelma using the senior synonym Cyriopagopus.
