Figure 7. Scanning electron microscopy, Loxosceles hirsuta Mello-Leit~ ao, 1931, female (MACN 21483), spinnerets. A, ventral view. B, right anterior lateral spinneret. Inset shows apex of the major ampullate gland spigot. C, posterior median spinnerets. Notice lack of spigots. D, left posterior lateral spinnerets. Ac, aciniform gland spigots; ALS, anterior lateral spinnerets; MAP, major ampulate gland spigot; MS, modified setae; Pi, piriform gland spigots; PLS, posterior lateral spinnerets; PMS, posterior median spinnerets. Scale bars = A, 0.1 mm; B, 0.02 mm; C–D, 0.05 mm.

B, Hexophthalma hahni (Karsch, 1878) comb. rest. female (TM 6511), right chelicera, posterior view. Note absence of fang serrula. C, same, detail of the apex of the cheliceral lamina. D, Hexophthalma spatulata (Pocock, 1900) comb. nov., female (TM 13600), right palp, prolateral. CL, apex of chelicera lamina; F, chelicera fang; FS, fang serrula; FT, femoral thorns; MS, membranous sheath; PL, promarginal lobe of the chelicera. Scale bars: A–C, 0.1 mm; D, 0.5 mm.
