Paratypes :
4 ♂♂ and 6 ♀♀, idem, 30 Aug. 2011, 28 ♂♂ and 10 ♀♀ (Coll. Kuhlmann, BMNH, RBINS, SANC,CUIC).

Male
Close to L. mosselinum but all tarsi pale yellow and not so long (Fig. 12C) (mid and hind tarsi brown in L. mosselinum and L. timmermanni). Metapostnotum with rugae extending 2/3 distance to posterior margin (extending 4/5 distance in L. tigrinum).

This is the priority name for L. fynbosense.
Here are pictures of the type from Mossel Bay, ix.1933, leg. RE. Turner (BMNH), examined December 2011.

Type material Halictus mosselinus (1 specimen). Holotype ♀, Cape Province, Mossel Bay, ix. 1933 (white label), S. Africa, R.E. Turner, Brit. Mus. 1933-552 (white label), Type (red-white label), B.M. TYPE HYM. 17a.1109 (white label), Halictus mosselinus Ckll Type (handwritten white label), BMNH.

Male
Body length 7.5 mm. Wing length 6 mm. Legs very long, especially tarsi (length of posterior tarsi equal to length of mesosoma), totally black to blackish brown except foretarsi yellowish brown (all tarsi yellowish in L. hantamense and L. tigrinum). Metapostnotum with longitudinal ridges. Dorsolateral slopes of propodeum shining, punctate. Punctation of mesoscutum sparse between parapsidal lines (i = 3–4d) (denser in L. timmermanni). Metasoma blackish, sometimes partly
orange red. Gonostylus with long apical setae (longer than basal width of gonostylus).

Female
Body length 7 mm. Wing length 6 mm. Metasoma red, base of T1 and T5-T6 blackish (metasoma largely black in L. hantamense and L. tigrinum; T5 red in L. timmermanni). Metapostnotum with longitudinal ridges, dorsolateral slopes of propodeum shining (slopes shagreened in L. timmermanni). Punctation of mesoscutum sparse between parapsidal lines (i = 2d).

Lasioglossum (Capalictus) tigrinum Pauly, Gibbs & Kuhlmann 2012
Holotype Male : South Africa, Plateau Hantam Mts, near antenna, 9 km N. Calvinia, 31°22’29 »S 19°47’03 »E, 1570m, 30.viii.2011, leg. M. Kuhlmann.
Paratypes: idem holotype, 1 male, 1 female.

Diagnose.
Male. Close to L. hantamense but all tibiae (except a dark central maculation on tibiae II and III), tarsi, apical margins of terga and sterna yellowish orange (Fig. 12D). Mid and hind tarsi black in L. mosselinum and
L. timmermanni).

Female close to L. hantamense but body size larger, T1 and T2 distinctly punctate in middle of disc as on apical margin (fig. 7D), punctation of mesoscutum denser (fig. 7B). Differs from L. mosselinum and L. timmermanni by the largely black metasoma.

Lasioglossum (Capalictus) timmermanni Pauly, Gibbs & Kuhlmann 2012
Holotype male: South Africa, Farm Papkuislfontein, 20 km S. Nieuwoudtville, Fynbos, 31°33'16"S 19°08'31"E, 680m, 15.viii.2010, leg. M. Kuhlmann (NCIS).

Material identified. South Africa, Farm Avontuur, Fynbos, 12km NW Nieuwoudtville, 31°16’18 »S 19°02’55 »E, 770m, 25.viii.2010, 1MMM, leg. M. Kuhlmann.

Diagnosis
Male
Close to L. mosselinum but punctation of mesoscutum much denser between parapsidal lines (i =1-1.5d) (sparse in L. mosselinum, I = 3-4d). Legs completely black, tarsi shorter than those of L. mosselinum (all tarsi pale yellow to yellow-orange in L. hantamense and L. tigrinum, fore tarsus yellow in L. mosselinum).
Female
Close to L. mosselinum but metasoma with more extensive red colouration on last tergum (Fig. 16F), base of first tergum often black (metasomal terga black with pale apical margins in L. hantamense and L. tigrinum). Rugae of metapostnotum are finer and shorter than in L. mosselinum, dorso-lateral slopes of propodeum with microtessellate dull surface, not shiny as in L. mosselinum.
