The specific epithet is a patronymic in honor of Dr Charles Haddad who collected the type specimens and for his contribution to arachnology in South Africa . Diagnosis. Males of L. haddadi sp. nov. , can be recognized inside of the “Group haddadi” by a very robust, darkly coloured tibia I ( Fig. 19J, K ) with a robust spur; and by a more elongated copulatory bulb ( Fig. 19 G–I). Females can be distinguished from L. engelbrechti sp. nov. , by the shape of their spermathecae with a longer stalk ( Fig. 20D ). Description. Male holotype (NCA 2007/1486, Fig. 19 A–K).
