Type material. Holotype ♀: SOUTH AFRICA: Western Cape: Fisherhaven, near Hermanus, 34°21.430’S, 19°07.557’E, 30.IX.2007, leg. C. Haddad & R. Lyle (sifting leaf litter) (NCA 2008/360).
Paratype: SOUTH AFRICA: Western Cape: Outeniquastrand, near George, 34°02.754’S, 22°17.037’E, 7.I.2015, leg. C. Haddad (base of grass tussocks), 1♀ (NCA 2015/1755).
Etymology. This species is named for terra typica, the Western Cape Province of South Africa, from which it is known.
Diagnosis. Females of L. capensis sp. nov. are most similar to those of L. murphyi sp. nov., but differ by the smaller copulatory openings and the slight curvature of the copulatory ducts (Fig. 80), which are respectively larger and strongly curved in the latter species (Fig. 82). Male unknown.
Description. Female (holotype, NCA 2008/360). Colouration (Fig. 45): carapace and chelicerae creamy-yellow; endites and labium cream; sternum cream, margins yellow-brown at coxae; femora cream, remaining segments creamy-yellow. Abdomen cream dorsally and ventrally.

Epigyne with weakly sclerotized recurved hemispherical ridges anteriorly, continuing along midline into posterior half, forming oval atria; copulatory openings transverse, situated in anteromesal part of atria; copulatory ducts narrow and initially directed posteriorly, bending laterally and diverging, with slight lateral bend before entering ovoid lateral spermathecae along their anterior margin; fertilization ducts on posteromesal margin of spermathecae, directed mesally (Figs 80, 81).
Additional material examined. None.
Variation. The single female paratype is 2.57 mm in total length.
Habitat and biology. Both of the known females had plugged epigynes. This species was sampled from the ground (leaf litter and grass tussocks) in the Fynbos and Thicket biomes of South Africa.
Distribution. Only known from two localities in the coastal parts of south-western South Africa (Fig. 44).
