Ginglymodesmus sumac View in CoL n. sp.
Fig. 3 View FIGURE 3 C; map Fig. 5 View FIGURE 5
Holotype: Male, Julius River, Tasmania, CQ344421 (41°09’14”S 145°01’41”E), 150 m, 26.viii.2005, R. Mesibov, QVM 23:46113.
Paratype: Male, Julius River, CQ343422 (41°09’11”S 145°01’36”E), 150 m, pitfall emptied 10.xi.2000, C. Carr, QVM 23:46112.
Diagnosis: Differing from G. tasmanianus and G. penelopae in bearing a subterminal pointed process on the distal section of the telopodite arising on the anterior rather than posterior side, and in the distal telopodite section dividing apically into a solenomere and a branch with a pointed rather than flattened tip.
Description: As for G. tasmanianus , but differing in gonopod details. Telopodite ( Fig. 3 View FIGURE 3 C) with long axis of distal section lateral to long axis of proximal section; distal section broadly divided at about twothirds its length into curved, opposing, subequal, anterolateral and posteromesal branches, the posteromesal branch (solenomere) bearing the prostatic groove and a small, mesally pointing tooth near its base. Spinelike process arising at about onequarter the length of the distal telopodite section on its anterolateral surface, terminating just distal to the level of the solenomere base.
Distribution and habitat: Known only from two neighbouring sites in cool temperate rainforest near the Julius River in northwest Tasmania ( Fig. 5 View FIGURE 5 ). The holotype was collected under moss on a rotting log of myrtle beech, Nothofagus cunninghamii .
Etymology: “ Sumac ”, proper name, noun in apposition. Named for a rivulet which rises in the area, “the Sumac ” is a large block of wet eucalypt forest and cool temperate rainforest in northwest Tasmania. The Sumac was wilderness until accessed for logging in the early 1970s; it now contains a 9860 ha reserve ( Sumac Forest Reserve) of undisturbed rainforest. I have collected forest litter invertebrates on many occasions in the Sumac since 1976 but did not find G. s u m a c until 2005, when I returned to the area to search for a second specimen, now the holotype.
Remarks: The hingelike structure in G. s u m a c has not yet been examined using scanning electron microscopy.
