Type material. Holotype ♀: SOUTH AFRICA: KwaZulu-Natal: Ndumo Game Reserve, Crocodile farm, 26°54.426’S, 32°19.185’E, 12.I.2007, leg. C. Haddad (under rocks) (NCA 2007/3068). GoogleMaps

Paratypes: SOUTH AFRICA: KwaZulu-Natal: Ndumo Game Reserve, Nyamiti Pan , 26°53.409’S, 32°17.576’E, 35 m a.s.l., 3.XII.2019, leg. C. Haddad & V. Swart (canopy fogging, Pappea capensis ), 2♂ 1♀ (NCA 2020/270) GoogleMaps .

Etymology. The species is named for Catharine Hanekom, Regional Ecologist of Ezemvelo KZN Wildlife for the Maputaland Region, in recognition of more than twenty years of logistical support to the senior author during arachnid surveys in northern KwaZulu-Natal Province.

Diagnosis. This species is most similar to A. balrog sp. nov., but females can be distinguished by their large copulatory openings and globular spermathecae ( Figs 39, 40 View FIGURES 39–43 ), which are small and transversely oval, respectively, in A. balrog sp. nov. ( Figs 34, 35 View FIGURES 34–38 ). Males of A. catharinae sp. nov. have a small sharp tooth-like retrolateral tibial apophysis in lateral view ( Figs 41, 43 View FIGURES 39–43 ), compared to an elongate spike-like retrolateral tibial apophysis in A. balrog sp. nov. ( Figs 29 View FIGURES 27–33 , 38 View FIGURES 34–38 ).

Description. Female (holotype, NCA 2007/3068). Colouration ( Fig. 9 View FIGURES 7–10 ): carapace and chelicerae yellow; labium and endites creamy-yellow; sternum cream, margins yellow-brown at coxae; femora creamy-yellow, remaining segments yellow; abdomen cream dorsally and ventrally.

Epigyne with elongate curved 6-shaped copulatory openings at anterior of epigynal plate ( Fig. 39 View FIGURES 39–43 ); copulatory ducts narrow, initially directed posteriorly, looping mesally and anteriorly before following path of faint external ridges around periphery of epigyne, laterally with distinct kink before continuing posteriorly, bending mesally before entering small globular spermathecae on their ventral surface; fertilization ducts on anterolateral margin of spermathecae, directed posteriorly ( Figs 39, 40 View FIGURES 39–43 ).

Male (paratype, NCA 2020/270). Colouration ( Fig. 10 View FIGURES 7–10 ): as for female.

Leg spination (leg I derived from second male paratype in NCA 2020/270): femora: I do 2, II do 2, III do 3 rl 1, IV pl 1 do 3 rl 1; patellae spineless; tibiae: I plv 2 rlv 2, II plv 2 rlv 2, III pl 2 rl 1 plv 2 rlv 1, IV pl 2 rl 2 plv 1 vt 2; metatarsi: I plv 1 rlv 1, II plv 1 rlv 1, III pl 3 rl 1 plv 1 vt 3; IV pl 3 rl 2 plv 1 vt 3; palp: femur do 1, other segments spineless.

Palp: patella with small proximal ventral bump-like apophysis; tibia slightly longer than broad, with small sharp tooth-like apophysis, with additional tiny basal tooth ( Figs 41, 43 View FIGURES 39–43 ); tegulum ovoid, with large curved apical tegular process distally; median apophysis absent; conductor massive, translucent and comma-shaped, covering most of ventral aspect of tegulum; embolus originating proximally on tegulum, curling proximally and prolaterally, curving gradually along prolateral margin of tegulum, bending sharply near distal end of cymbium ( Figs 41–43 View FIGURES 39–43 ).

Additional material examined. None.

Variation. Total length: females 3.03–3.20 (average 3.12, n = 2); males 2.35–2.75 (average 2.55, n = 2).

Habitat and biology. Both of the known females had plugged epigynes. This species was sampled from the ground and canopies of a short tree ( Pappea capensis ) in savanna habitats.

Distribution. Only known from the type locality in northern KwaZulu-Natal, South Africa ( Fig. 44 View FIGURE 44 ).
