description: Lasioglossum (Capalictus) sp. 2
Material
All ♀♀: 2 ♀♀ (CUIC) (metasoma black), SOUTH AFRICA, Western Cape Province (WCP), Kunje Farm, 760 m, 28 km SSE Citrusdal, 32°40.35’S 19°12.67’E, 23-25 Sep. 2001; 2 ♀♀ (CUIC) (metasoma red), WCP, Kunje Farm, 760 m, 28 km SSE Citrusdal, 32°40.35’S 19°12.67’E, 23-25 Sep. 2001; 4 ♀♀ (CUIC) (2 females Voucher 01-54) (metasoma black), WCP, 21 km N Hermanus, 157 m, 34°17.82’S 19°07.71’E, 28 Sep. 2001; 1 ♀ (Voucher O1-45) (CUIC) (metasoma red), WCP, Cape Agulhas, 34°49.92’S 20°00.14’E, 27 Sep. 2001; 1 ♀ (CUIC) (metasoma black), WCP, Betty’s Bay, botanical garden, 27 m, 34°21.14’S 18°55.62’E, 28 Sep. 2001.
Specimens from Hermanus (4 ♀♀ including Voucher 01-54) are similar in size and colour to L. tigrinum sp. nov., but their tergum 1 is nearly impunctate on the disc, punctures of the mesoscutum are larger and sparser, punctures on the face are stronger.
Specimens with black metasoma from Kunje Farm (2 ♀♀) and Betty’s Bay (1 ♀) are similar in size and colour to L. hantamense sp. nov. but punctures of the mesoscutum are stronger.
The specimen from Cape Agulhas (1 ♀, Voucher 01-45) is similar to L. timmermanni sp. nov. by its colouration (metasoma red, including last terga) and shagreened propodeum.
Specimens from Kunje Farm with red metasoma (2 ♀♀) are similar to L. timmermanni sp. nov. by red metasoma and shagreened propodeum, but differs by black last terga. They are smaller in size than the specimen from Cape Agulhas.
Key to species
Males
1. Tibiae of middle and posterior legs yellowish orange (except for a central dark maculation) (Figs 12D, 13D, 14 G-H); apical impressed area of terga largely amber translucent (Fig. 6D) ………………………………………………………………… L. (Capalictus) tigrinum sp. nov.
– Tibiae of middle and posterior legs dark; apical impressed area of terga black, rarely amber, apical rim slightly straw-coloured ……………………………………………………………………… (2)
2. All tarsi pale yellow (Figs 12C, 13C, 14 E-F); gonostylus with short setae, length less than ¼ basal gonostylus width (Fig. 15C) …………………………………… L (Capalictus) hantamense sp. nov.
– Tarsi of middle and posterior legs dark (Fig. 14 A-D); gonostylus with long setae, length subequal to or longer than basal gonostylus width (Fig. 15 A-B) ……………………………………………… (3)
3. Foretarsi black (Fig. 13B); punctation of mesoscutum denser (i = 1–1.5d) (Fig. 8B); dorso-lateral slope of propodeum with microtesselate dull surface (Fig. 8c) ……………………………………… ……………………………………………………………… L. (Capalictus) timmermanni sp. nov.
– Foretarsi yellowish (Fig. 13A); punctation of mesoscutum sparser (i = 3–4d) (Fig. 3B); dorso-lateral slope of propodeum shining (Fig. 3C) ………… L. (Capalictus) mosselinum (Cockerell, 1945) Females
1. Metasoma largely red (Fig. 10A, C) ……………………………………………………………… (2) – Metasoma black, apical margins pale (Fig. 11A, C) ……………………………………………… (3)
2. Terga 5–6 largely red (Fig. 16F); dorso-lateral slopes of propodeum shagreened (Fig. 9C, D); ridges of metapostnotum short and anastomosing (Fig. 9C, D; also Fig. 7 in Pauly et al. 2008) ……………………………………………………………… L. (Capalictus) timmermanni sp. nov.
– Terga 5–6 blackish (Fig. 16E); dorso-lateral slopes of propodeum shining (Fig. 2D); ridges of metapostnotum more linear (Fig. 2D, also Fig. 6 in Pauly et al. 2008)……………… ……………………………………………………… L. (Capalictus) mosselinum (Cockerell, 1945)
3. Smaller body size (length 6-6.5 mm); T1 nearly impunctate on disc, punctures very weak and superficial, apical margin with fine punctures (Fig. 5D, E)…… L. (Capalictus) hantamense sp. nov.
– Larger body size (length 7 mm); T1 with distinct punctuation on disc as well as on apical margin (Fig. 7D, E) ...……………………………………………………… L. (Capalictus) tigrinum sp. nov.
Molecular results
DNA sequence data from five specimens of Lasioglossum (Capalictus) (1 specimen of L. hantamense sp. nov., 2 of L. tigrinum sp. nov., and 2 of L. aff. tigrinum (n°01-54) includes putatively fixed characters suggestive of species-level differentiation. A total of 1934 bp was sequenced for all five specimens (EF1-α: 951 bp, wnt-1: 457 bp, and opsin: 525 bp). Lasioglossum hantamense sp. nov. differed from L. tigrinum sp. nov. by 7 nucleotide substitutions (3 in EF-1α, 1 in wnt-1, and 3 in opsin) and from L. aff. tigrinum by 9 nucleotide substitutions (5 in EF-1α and 4 in opsin). Lasioglossum tigrinum sp. nov. differed from L. aff. tigrinum by 10 nucleotide substitutions (4 in EF-1α, 1 in wnt-1, and 5 in opsin). Only one variable nucleotide position was found within L. aff. tigrinum (in EF-1α) and 2 were found in L. tigrinum sp. nov. (1 each in EF-1α and opsin). The levels of genetic differentiation in EF-1α are consistent with those discovered between other closely related bee species (Danforth et al. 1999; Kuhlmann et al. 2007).
