FIGURES 27–30. Archaeonebria inexspectata gen. n., sp. n., light microscopic images of paratypes #1 (Figs 27, 28, 30) and #2 (Fig. 29). Fig. 27, prothorax and part of the head, ventral aspect. Fig. 28, left labial palpus; the arrows point to the three setae inserted on the penultimate palpomere. Fig. 29, left metatarsomeres II–V.
