Subfamily Bruchinae Remarks: Caryedon gonagra used to be confused with the groundnut seed beetle, Caryedon serratus (Olivier, 1790) (Delobel et al., 2003). Its larvae feed in .the seeds of various Alex Delobel Caesalpinioideae, including tamarind (Tamarindus indica), Gleditsia triacanthos, Senna didymobotrya and various species of Cassia and Bauhinia; also reared from Mimosoid seeds: INTRODUCTION Acacia farnesiana, A. tortilis raddiana, Dichrostachys cinerea, possibly also Prosopis juliflora. Adult size varies widely according to the size of the seed in which larval Bruchinae are commonly known as 'seed beetles' because their larval development takes development has taken place; specimens from UAE are usually very small as compared with place within the fruits and seeds of trees and herbaceous plants. Their main hosts are specimens reared from tamarind or Bauhinia. Leguminosae (Fabaceae or Papilionoideae), but a large number of other botanic families are Distribution: From Egypt to Australia, including India, Sri Lanka, Thailand, Vietnam, and also attacked (see Johnson, 1990; Kergoat et al., 2008). The seed beetle fauna of the Arabian New Caledonia. New to the UAE. Peninsula is relatively well known since the publications ofDecelle (1979, 1990) and Anton (1994a, 1994b, 2000), dedicated to the Yemeni, Saudi Arabian and Omani faunas.

Two additional female A. senega!, A. seyal, A. sieberiana, A. tortilis raddiana and A. tortilis spirocarpa (Anton & specimens of Bruchidius could not be definitely identified. Delobel, 2004). Distribution: Senegal, Mauritania, Morocco, Mali, Burkina Faso, Libya, Egypt, Israel, Jordan, MATERIALS AND METHODS Saudi Arabia, Yemen, Oman. New to the UAE. Most specimens have been collected using different kind of traps, mainly light traps, Malaise Caryedon sudanensis Southgate, 1971 . Plate 4 traps and water traps.

If not otherwise stated, the specimens from Egypt, Israel, Jordan, Iran, Pakistan, Saudi Arabia, Oman and Yemen (Decelle, 1979). were collected by A. van Harten. The main difference between the two species is the presence of an additional pair of small sclerites in the internal sac in C. yemenensis; knowing that the number of smaller sclerites SYSTEMATIC ACCOUNT may vary in some Caryedon species (e.g. C. pallidus (Olivier, 1790), personal observation), it may be hypothesized that yemenensis is not more than a form of sudanensis.
