Diagnosis

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).

Female

Differs from L. mosselinum and L. timmermanni by black metasoma (Figs 5E, 11A) and dull shagreened dorso-lateral slopes of propodeum (Fig. 5C). T1 nearly impunctate, punctures very fine, indistinct (numerous distinct punctures in L. tigrinum).

Etymology

The specific epithet refers to the Hantam Mountains near Calvinia where the species was first discovered.

Description

Male

BODY LENGTH. 6.5-7 mm.

FOREWING LENGTH. 5.5 mm.

COLOURATION. Head and mesosoma black. Metasomal terga black with apical rim translucent strawcoloured. Clypeus and mandibles completely black. Flagellum with ventral surface black. Wing membrane subhyaline, venation, pterostigma and tegula brown. Legs black except femoral apices and tibial bases brown and all tarsi pale yellow.

PUBESCENCE. Face below antennal sockets with dense appressed greyish white setae. Long erect setae on scape, vertex and gena (2-2.5 OD). Metanotum, side of mesosoma, propodeum on lateral and posterior surfaces with sparse, short, greyish white and plumose setae (2-2.5 OD). Metasomal terga without patches of tomentum but with sparse and short setae on lateral parts of terga. Metasomal sterna nearly glabrous except some long setae laterally.

SURFACE SCULPTURE. Clypeus and supraclypeal area finely and densely punctate. Frons with minute contiguous punctures (i <d) of velvet-like appearance. Upper paraocular area shagreened and irregularly micropunctate. Vertex rugulose to shagreened. Gena dull and ruguloso-striate. Mesoscutum smooth with punctures separated by puncture width (i = 1-1.5 d), punctures denser laterally of parapsidal lines (i = 0.5d). Mesoscutellum and metanotum more finely punctate (i = 0.5-1d). Preepisternum, hypoepimeral area and metepisternum with minute contiguous punctures. Mesepisternum with larger and more widely spaced punctures, spaces between punctures shining (i = 0.5d). Metapostnotum rugae relatively weak, extending no more than 2/3 distance to posterior margin. Dorso-lateral slopes of propodeum dull shagreened. Lateral surface of propodeum dull and minutely roughened, indistinctly punctate. T1 moderately punctate (i = 1-1.5d), impressed apical margin with few with punctation similar to T1, disc of T4 and T5 with sparse piliferous punctures.

STRUCTURE. Head nearly as long as wide (length/width ratio = 0.94). Eyes converging below (UOD/LOD ratio = 1.62). Flagellomeres long (F2-F10 length/diameter ratio 1.8-1.5). Vertex short. Gena narrower than eye. Propodeum without carina, dorsal surface relatively long (MMR = 1.8). Legs moderately long (length of posterior tarsus equal to 0,7 length of mesosoma) (Figs 13C, 14 E-F).

TERMINALIA. Gonostylus pointed apically, laterally covered with short setae (less than 1/4 basal width of gonostylus) (Fig. 15C).

Female

BODY LENGTH. 6-6.5 mm.

FOREWING LENGTH. 5 mm.

COLOURATION. Head, mesosoma, metasoma and legs black. Metasomal terga black with apical rim translucent straw-coloured. Wing membranes subhyaline, venation, pterostigma and tegula brown.

PUBESCENCE. Greyish white and sparse. Metasomal terga without patches of tomentum, apical rim of T2-T4 with sparse fringes.

SURFACE SCULPTURE. Clypeus shiny with large and sparse punctures. Supraclypeal area shiny with fine punctures. Frons dull and finely rugulose, with velvet-like appearance. Paraocular area and ocellocular area finely and densely punctate, semi-dull. Lower paraocular area shining and sparsely punctate. Vertex shagreened. Gena finely and densely strigose-punctate. Mesoscutum smooth and shining with sparse punctures (i = 1–2d), punctures denser anteriorly and laterally of parapsidal lines (i = d). Mesoscutellum more finely and densely punctate, shiny medially. Metanotum dull matt with minute contiguous punctures. Preepisternum, mesepisternum and metepisternum dull matt, minutely roughened. Hypoepimeral area minutely and densely punctate.

METAPOSTNOTUM. It is with weak anastomosing rugae extending no more than 2/3 distance to posterior margin. Lateral surface of propodeum minutely roughened and shagreened. T1 smooth and nearly impunctate on disc, apical margin finely punctate (i = 1.5d). T2 punctate on basal and apical margins, impunctate in middle of disc. T3-T4 with very sparse punctation.

STRUCTURE. Head nearly as long as wide (length/width ratio = 0.91). Eyes slightly convergent below (UOD/LOD ratio = 1.09). Vertex short. Gena as wide as eye. Inner metatibial spur with five short teeth. Metapostnotum moderately long (MMR = 1.25). Propodeum with very weak lateral and oblique carinae curved to the middle of the posterior surface.
