ACUSILAS SIMON, 1895 View in CoL

Phonognatha vicitra Sherriffs, 1928 .

India: South Coorg , Sidapur, Charlotte Estate, xii.1928, 3000 ft, W. R. Sherriffs, 4 females, 3 juveniles (collection unknown, not examined) .

This spider is described from far beyond the known distribution of Phonognatha and its close relatives (known only from Australia, New Caledonia and Papua New Guinea), and seems to have been allocated to that genus based on its colour pattern and leaf curl. However, examination of similar specimens (S. Kulkarni) and photos (M. Siliwal) suggest this species is an Acusilas based on its raised pars cephalica, more irregular dorsal markings and similarity of the epigyna. Both are araneids that make leaf-curl retreats, and confusing the two is not difficult (see Fig. 3B).

TETRAGNATHIDAE MENGE, 1866 View in CoL

Deliochus pulchra Rainbow, 1916 View in CoL . Australia, Queensland, Gordonvale , 30.vi.1912, W. J. Rainbow, holotype (AM KS 6475 ) (AM, examined).

Deliochus pulchra melania Rainbow, 1916 View in CoL . Australia, Queensland, Gordonvale , 15.vi.1912, W. J. Rainbow, holotype (AM KS 8841 ) (AM, examined).

These two taxa were described based on specimens collected in Gordonvale, Queensland, Australia. Both are erroneously named D. pulcher in the World Spider Catalog (2017), and the label for the subspecies is misidentified as D. pulchra melania View in CoL . Based on their trapezoidal (rather than square) endites and simple epigyna, we suggest that these are tetragnathids, likely within Nanometinae. However, the tetragnathids of Australia are relatively little known with numerous undescribed genera and species (Álvarez-Padilla and Hormiga, unpublished). As such, they cannot be reliably placed in a tetragnathid genus but are certainly not Deliochus View in CoL .
