Diagnosis

Ƌ. 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 View Fig ). Mid and hind tarsi black in L. mosselinum and L. timmermanni punctate in middle of disc as on apical margin ( Fig. 7D View Fig ), punctation of mesoscutum denser ( Fig. 7B View Fig ). Differs from L. mosselinum and L. timmermanni by the largely black metasoma.

Etymology

The name refers to the distinctive yellow-orange banding of the male metasoma which is striped like a tiger.

Description

Male

BODY LENGTH. 7.5 mm.

FOREWING LENGTH. 6 mm.

COLOURATION. Head and mesosoma black. Terga black with the whole apical impressed margin amber translucent. Metasomal sterna yellowish orange. All tarsi and tibiae (except a central dark maculation on tibiae II and III) yellowish orange. Clypeus, mandible and ventral surface of flagellum black. Wing membrane subhyaline, venation, pterostigma and tegula dark brown

PUBESCENCE. Face below antennal sockets with dense appressed greyish white setae. Long erect setae on scape, vertex and gena (2-2.5 OD). Metanotum, sides of mesosoma, propodeum on lateral and posterior surface with sparse, short, greyish white and plumose setae (2-2.5 OD). Metasomal terga with sparse and short setae on lateral parts of terga. Metasomal sterna nearly glabrous except some short and sparse setae.

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 one puncture width (i = d), punctures denser anteriorly and laterally of parapsidal line(i = 0.5d) ( Fig. 8b View Fig ). Preepisternum, hypoepimeral area, metepisternum as well as mesepisternum with minute, contiguous punctures. Metapostnotum rugae relatively weak, extending 4/5 distance to posterior margin. Dorso-lateral slope of propodeum dull shagreened. Lateral surface of propodeum dull and minutely roughened, indistinctly punctate. T1 moderately-densely punctate (i = 0.5–1d), impressed apical margin with few minute punctures. T1 anterior surface smooth, without striations. Discs of T2 and T3 with punctation similar to T1, discs of T4 and T5 with sparser punctures.

STRUCTURE. Head nearly as long as wide (length/width ratio = 0.97). Eyes converging below (UOD/LOD ratio = 1.70). Flagellomeres long (F2-F10 length/diameter ratio 1.6–1.4). Vertex short. Gena narrower

than eye. Propodeum without carina, dorsal surface relatively long (MMR = 1.66). Legs moderately long (length of posterior tarsi equal to 0,85 length of mesosoma) ( Figs 13D View Fig , 14 View Fig G-H).

TERMINALIA. Gonostylus pointed apically, laterally with some long setae (longer or subequal to basal width of gonostylus) ( Fig. 15D View Fig ).

Female

BODY LENGTH. 7 mm.

FOREWING LENGTH. 5 mm.

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

PUBESCENCE. Greyish white and sparse. 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. Upper 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 line (i = d) 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 distinctly punctate in middle of disc as well as on apical margin (i = 1.5d), smooth and impunctate anteriorly and laterally. T2 punctate in middle of disc as on apical margin. T3-T4 with sparse punctures.

STRUCTURE. Head nearly as long as wide (length/width ratio = 0.90). Eyes slightly convergent below (UOD/LOD ratio = 1.13). Vertex short. Gena as wide as eye. Inner metatibial spur with five short teeth. Metapostnotum moderately long (MMR = 1.56). Propodeum with very weak lateral and oblique carinae curved to the middle of the posterior surface.
