Thus, here its neotypeis designated, according to ICZN (2000, chapter 16, article 72.4.5.), since the specimen fits all morphological characteristics presented in the original description and was collected from the type locality ( Fig. 2), Kirstenbosch, CapeTown.   Examined type material.  Neotypefemale designed on slide ( SAM/ IZIKO): South Africa, Cape Town, Ta-ble Mountain National Park, Kirstenbosch, 33°58’55.0”S, 18°25’25.0”E( Fig. 2), Afrotemperate Forest,  400 m,  12.ii.2009, Pitfall trap, C Uyscoll.  Other examined material.  2 femalesin slides ( INPA): same data as neotype. 1 femalein slide and  1 specimensin alcohol ( INPA): South Africa, Cape Town, Table Mountain National Park, Orange Kloof, 34°00’12.3”S, 18°23’25.8”E, Afrotemperate Forest,  130 m,  28.i.2009, Sugar-baited Ant trap, C Uyscoll.  6 specimensin alcohol ( CC/ UFRN): Cecilia-Rooikat, 33°59’36.9”S, 18°25’11.0”E, in Fynbos,  430 m,  21.ii.2009, Sugar-baited Ant trap, C Uyscoll. 4 femalesin slides and  11 specimensin alcohol ( CC/ UFRN): Tokai, 34°03’54.3”S, 18°24’10.2”E, in Pine Plantation,  300 m,  19.i.2009, Sugar-baited Ant trap, C Uyscoll.   Diagnosis.Body all dark blue but depigmented in dorsal head, few trunk parts, tibiotasus and dens distally ( Fig. 18); head mac A0, A2–3, A5, M1–2, S0–3, S5–6, Pa3, Pm3, Pp3and Pp5present, M4ias mac or mic; prelabral chaetae smooth; labial papilla E with l.p. apically pointed and surpassing the base of a.a.
