Figs 21–26 in The Nemesia trapdoor spider fauna of the Maltese archipelago, with the description of two new species (Araneae, Mygalomorphae, Nemesiidae)
Figs 21–26. Male diagnostic features for species of Nemesia Pocock, 1903. 21–22. Dorsal palp tibia, PTR is present in all species of Nemesia for which information is available, here illustrated by two species from the eastern and western ends of the Mediterranean distribution range of the genus; N. cellicola Audouin, 1826 (21) from the Middle East and N. bacelarae Decae, Cardoso & Selden, 2007 (22) from Portugal. 23–24. Dorsal palp tibia of the only Nemesia species known in which the PTR is absent; N. arboricola Pocock, 1903 (23) from Malta and N. simoni O. Pickard-Cambridge, 1874 (24) from the western Pyrenees. 25–26. Difference in distal palp morphology (retrolateral view) showing differences in tibia and palpal organ that distinguish N. arboricola (25) from N. simoni (26).
Figs 27–35. Nemesia arboricola Pocock, 1903 in The Nemesia trapdoor spider fauna of the Maltese archipelago, with the description of two new species (Araneae, Mygalomorphae, Nemesiidae)
Figs 27–35. Nemesia arboricola Pocock, 1903, ♂ reference specimen (TD.4, NHMR). 27. Dorsal habitus. 28. Prosoma lateral, note slight elevation of the cephalic part, ocular process and gradual posterior slope of thoracic part. 29. Metatarsus and tibia leg I, note tibial apophysis (TA), tibia spur (TS), clasper field (CF). 30. Prolateral patella III with single spine (SS). 31–34. Right palpal organ in four different positions rotated clock-wise by 90°. 31. Ventral view, 32. Prolateral view. 33. Dorsal view. 34. Retrolateral view. 35.

Figs 1–8 in The Nemesia trapdoor spider fauna of the Maltese archipelago, with the description of two new species (Araneae, Mygalomorphae, Nemesiidae)
Figs 1–8. Characters reported to distinguish N. arboricola Pocock, 1903 from N. macrocephala Ausserer, 1871 in Kritscher (1994). 1–4. N. arboricola; represented by two specimens (TC.016, NHMR, Figs 1 & 3, specimen collected from an arboreal-nest; TC.017, NHMR, Figs 2 & 4, specimen collected from a terrestrial nest). 5–8. N. macrocephala; represented by two specimens (Isaia.046, Figs 5 & 7 and Isaia.047, Figs 6 & 8), both collected from terrestrial nests near the type locality, Palermo, Sicily. 1–2, 5–6. Comparative eye-formations. Note the overlap and variation in distances between ALE and PLE (ALE–PLE N. arboricola ranges between 0.10–0.20, n = 7; N. macrocephala ranges between 0.14– 0.22, n = 2). Furthermore, note the variation in general configuration of the eyes that renders species recognition on these characters uncertain. 3–4, 7–8. Comparative shapes of spermathecae in ventral view. Note both similarities and differences in shape and differences in distance between receptacles of both species that renders unambiguous species recognition difficult, although spermathecal receptacles in N. arboricola shown here are somewhat smaller and finer built. Scale bars = 1 mm.
