African Arthropods/Philanthus

There are 17 species in South Africa (Pulawski 2023):

• Philanthus bucephalus
• Philanthus capensis
• Philanthus fuscipennis
• Philanthus histrio
• Philanthus impatiens
• Philanthus loeflingi
• Philanthus major
• Philanthus melanderi
• Philanthus namaqua
• Philanthus natalensis
• Philanthus oraniensis
• Philanthus pilifrons
• Philanthus promontorii
• Philanthus rugosus
• Philanthus strigulosus
• Philanthus triangulum

• 
  Philanthus triangulum diadema on Sleepy Morning Waltheria indica
• 
  Philanthus triangulum diadema

• Philanthus turneri

All are described in Arnold (1925). However:

• Philanthus major is not in the key - Arnold (1925) merely presents the original description (Kohl, 1891) translated into English.
• Philanthus promontorii - only the male has been described; Arnold (1925) states that it is "closely allied to capensis Dahlb., and probably only a race of that species".
