(Figure 4B)
Ischnocolus jickelii L. Koch 1875: 58, pl. 6, f. 2 (Df); Guadanucci & Gallon 2008: 42 (S). Chaetopelma adenense Simon 1890: 83 (Df).
Type material
Holotype female (BMNH 19-9 - 18-5698 -99) from Ethiopia; not located, not examined.
Note
Smith (1990) stated that the specimen in the Koch collection is a juvenile and that the species should be suspended until more material has been discovered. As listed below, additional material was studied and, therefore, I. jickelii is here considered a valid species.
Additional material
DJIBOUTI: Obock: 1f (MNHN 22250); 13j (MNHN 19152); ETHIOPIA: Abyssinia: 1f (MNHN 3284); Adayalla: 1f and 3j (MNHN 22257); SOMALIA: Mogadishu: 2f (MRAC 147156), January 1945, P. Accigliaro leg.; YEMEN: Aden: 1f (BMNH 95.5.22-16), 6 February 1995; 1f, type specimen of Chaetopelma adenense (MNHN 9976).
Diagnosis
Female representatives can be distinguished from congeners by the spermathecae formed by two receptacula with a wide base, bearing a large apical lobe with two small lateral lobes, and small lobes below the apical region (Figure 4B). Males unknown.
