  6. Scientific experience Taxonomy and phylogenetics of the spider family Ctenidae (Neotropical)

  7. Ctenidae: diagnostic characters Ocular pattern: 2-4-2

  8. Ctenidae: characters Claw tufts Tarsal scopulae

  19. PhD Project “Taxonomy of the Neotropical spider genus Celaetycheus Simon and cladistic analysis of Cteninae (Araneae, Ctenidae)” • Phylogenetic relationships of Cteninae (Ctenidae) • Taxonomic revision of Celaetycheus Simon ok

  20. Cladistic Analysis: Preliminar results Ctenidae Cteninae

  21. Cladistic Analysis: Preliminar results Ctenidae Cteninae

  22. GTI Program • Goals • -Examine of Afrotropical material for the cladistic analysis • Taxonomy of Afroneutria gen. nov. • Taxonomy of Arctenus gen. nov.

  23. Cladistic Analysis New data 1 7 + 14 = 21 41

  24. Cladistic Analysis New data Mesquite: 67 taxa and 75 characters

  25. Cladistic Analysis New data Ctenidae Cteninae Result: 48 trees of 175 steps

  26. Calocteninae

  27. Cteninae Afrotropical taxa

  28. Taxonomy Afroneutria, a new Afrotropical spider genus (Araneae, Ctenidae, Cteninae) Composed by median to large sized spiders. Distribution: Central Africa. Four species: Afroneutria velox, A. immortalis, A. erythrochelis and A. quadrimaculata sp. nov.

  29. Taxonomy Afroneutria, a new Afrotropical spider genus (Araneae, Ctenidae, Cteninae) Composed by median to large sized spiders. Distribution: Central and south-east Africa. Four species: Afroneutria velox, A. immortalis, A. erythrochelis and A. quadrimaculata sp. nov.

  30. Taxonomy Afroneutria, a new Afrotropical spider genus (Araneae, Ctenidae, Cteninae) Distribution: Central Africa.

  31. Taxonomy Afroneutria, a new Afrotropical spider genus (Araneae, Ctenidae, Cteninae) Distribution: Central Africa.

  32. Taxonomy Arctenus, a new Afrotropical spider genus (Araneae, Ctenidae, Calocteninae) Composed by small sized spiders. Distribution: South-east Africa. One species: Arctenus taita sp. nov.

  33. Taxonomy Arctenus, a new Afrotropical spider genus (Araneae, Ctenidae, Calocteninae) Composed by small sized spiders. Distribution: South-east Africa. One species: Arctenus taita sp. nov.

  34. Taxonomy Arctenus, a new Afrotropical spider genus (Araneae, Ctenidae, Calocteninae) Distribution: South-east Africa.

  35. Taxonomy Arctenus, a new Afrotropical spider genus (Araneae, Ctenidae, Calocteninae) Distribution: South-east Africa.

  36. Taxonomy Arctenus, a new Afrotropical spider genus (Araneae, Ctenidae, Calocteninae) Distribution: South-east Africa.

  37. Discussion • Problems with terminal taxa: several Neotropical taxa and just a few of others regions • Cteninae: older than the split of the continent? • Arctenus new genus: first Calocteninae from the Afrotropical region • Afroneutria new genus: large size spiders and related to Phoneutria in the cladistic analysis: public helth problem?
