The jimna -complex

The jimna -complex Rix et al., 2020: 707 .

Remarks. The monophyletic jimna -complex of Namea ( Fig. 13 ) currently includes two previosuly described species ( N. bunya Raven, 1984 and N. jimna Raven, 1984 ), one new species described in the current study ( N. nigritarsus sp. nov.), plus a number of undescribed species from south-eastern Queensland and north-eastern New South Wales, where the spiders are usually rare in nature and restricted to rainforest habitats ( Rix et al. 2020). Burrows are of the ‘wishbone’ type with a branching second shaft and concealed second entrance, with the main burrow entrance usually in the form of an irregular open hole lined with flocculent white silk, the latter of which may fan out beyond the burrow entrance ( Fig. 12 ). Only a single species has been recorded on the D’Aguilar Range.

Figures

FIGURE 13. Phylogeny of the genus Namea modified from Rix et al. (2020; fig. 2), inferred from a partitioned Bayesian analysis of that study’s ‘FULL’ dataset (151 taxa, 5,261 bp, 50% majority-rule consensus tree). Clades corresponding to 30 morpho-species OTUs are collapsed for the genus Namea (square brackets denote the number of specimens included in each clade), and nodes have a posterior probability of ≥ 0.98 unless otherwise stated. Seven species recorded from the D’Aguilar Range (south-eastern Queensland) are highlighted in enlarged bold text; note that specimens of an eighth species, N. gloriosa sp. nov., were not sequenced for this study.
