Diagnosis
Male
Close to L. mosselinum but punctation of mesoscutum much denser between parapsidal lines (i = 1-1.5d) ( Fig. 8B View Fig ) (sparse in L. mosselinum , I = 3-4d). Legs completely black, tarsi shorter than those of L. mosselinum ( Figs 12B View Fig , 13B View Fig , 14 View Fig C-D) (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 View Fig ), 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 ( Fig. 9 View Fig C-D).
Etymology
The species is named for Kim Timmermann, formerly Münster ( Germany), who collected many of the specimens.

Description
Male
BODY LENGTH. 7.5 mm.
FOREWING LENGTH. 6 mm.
COLOURATION. Head, mesosoma, terga, sterna, clypeus, mandible, antenna and legs black.Wing membrane subhyaline, venation, pterostigma and tegula black.
PUBESCENCE. Face below antennal sockets with dense appressed greyish white setae. Long erect setae on scape, vertex and gena (2-2.5 OD). Metanotum, pleuron, propodeum on lateral and posterior surface 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. Metasomal sterna nearly glabrous except some long and sparse setae on lateral sides.
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 and ocellocular area rugulose to shagreened. Gena dull and ruguloso-striate. Mesoscutum smooth with punctures separated by more than a puncture width (i = 1-1.5d), punctures denser laterally of parapsidal lines (i = 0.5d) and anteriorly. Mesoscutellum more finely punctate (i = 0.5-1d). Metanotum with contiguous fine punctures. Preepisternum, hypoepimeral area and metepisternum with contiguous minute punctures. Mesepisternum with larger alveolate and contiguous punctures. Metapostnotum rugae relatively weak and anastomosing, extending more than 4/5 distance to posterior margin. Dorsolateral slopes of propodeum dull shagreened. Lateral surface of propodeum dull with distinct dense punctures. T1 moderately punctate (i = 1-1.5d), impressed apical margin without punctures. T1 anterior surface smooth and without striations. Disc of T2 and T3 with punctation similar to T1, disc of T4 and T5 with sparse piliferous punctures.
STRUCTURE. Head rounded, nearly as long as wide (length/width ratio = 0.91). Eyes converging below (UOD/LOD ratio = 1.69). Flagellomeres long (F2-F10 length/diameter ratio 1.5-1.7). Vertex short. Gena narrower than eye. Propodeum without carina, metapostnotum relatively long (MMR = 1.42). Legs moderately long (length of posterior tarsi equal to 0,8 length of mesosoma) ( Figs 13B View Fig , 14 View Fig C-D).
TERMINALIA. Gonostylus pointed apically, with relatively long apical setae (subequal to basal width of gonostylus) ( Fig. 15B View Fig ).
Female
BODY LENGTH. 7 mm.
FOREWING LENGTH. 6 mm.
COLOURATION. Head, mesosoma and legs black, metasoma red orange except T1 anterior surface black and lateral parts of T2-T4 blackish. Wing membranes subhyaline, venation, pterostigma and tegula brown.
PUBESCENCE. Greyish white and sparse. Metasomal terga without patches of tomentum.
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 = 2–3d), punctures denser anteriorly and laterally to parapsidal line (i = d). Mesoscutellum more finely and densely punctate, shiny medially Metanotum dull matt with minute contiguous punctures. Preepisternum, and mesepisternum dull matt, minutely and densely roughened. Hypoepimeral area and metepisternum minutely and densely punctate. Metapostnotum 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 basis and apical margin, not in the middle. T3-T4 with very sparse punctures.
SCULPTURE. Head nearly as long as wide (length/width ratio = 0.89). 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 = 1.48).
PROPODEUM. It is with very weak lateral and oblique carina curved to the middle of the posterior surface.
Additional material
The following specimens are identified as Capalictus , but not described as new because only a single sex is known. They differ slightly from the species above by the punctation of mesoscutum and metasomal terga. The information is provided to encourage and facilitate future study of the subgenus.
