Ecdamua cadenati ( Risbec, 1951)

Plesiostigmus cadenati Risbec, 1951: 321-323 . Ecdamua cadenati: BOUČEK (1976) : 347, GRISSELL (1995): 188, ZAVADA (2005): 158.

Material examined. CAMEROON: Bamenda Hosp., 4,800’, 7.xii.1937, M. D. W. Jeffrys (1 J 1 ♀, BMNH). GAMBIA: Fajara, 26.i.1978, L. Huggert (1 ♀, BMNH). GHANA: Tafo, 14.iv.1961, M. R. Smith, R. Eady det. (1 ♀, BMNH). ZAMBIA: Lusaka, vii.1980, R.A. Beaver (1 ♀, BMNH). ZIMBABWE: Salisbury (= Harare), ii.1976, A. Watsham (1 ♀, BMNH).

Distribution. Nigeria, Senegal, Sierra Leone, Uganda (BOUČEK 1976, GRISSELL 1995); Niger ( ZAVADA 2005). This is a new species for Cameroon, Gambia, Ghana, Zambia, and Zimbabwe. Comments. This species is very similar to E. macrotelus Walker, 1862 ; it differs only in having the basal cell opened distally (without cubital setal line) and possessing a median groove anteriorly on the scutellum (BOUČEK 1976). However, both species are extremely variable (e.g. in colour, body size, sculpture, shape of antennae) and it seems that these characters are not fully reliable. Moreover, the distribution of both species is overlapping. It would be useful to make a detailed morphometric study on a large number of specimens to verify their species status.
