  Type data:

   Holotype QM T196226 ♂ (coll: H. Hacker, 19.x.1925), Southport, Queensland.

 

Introduction

This species is named in honour of Arnold Jacobi whose publications on the Australian fauna were very significant. Specimens in the type series of this species in Stockholm and Dresden are labelled as the type series of Leptolamia praetextata apparently by Jacobi himself but Löcker (2014) has demonstrated that these specimens do not match either the description nor the type locality of L. praetextata. Löcker (loc. cit) was able to locate the true type series for L. praetextata and recognised the mislabelled specimens as representing a new species which she dedicated to Jacobi. The species is restricted to SE Queensland and the New South Wales North Coast.

Diagnosis

Colour. Vertex light brown; frons mid brown, carinae paler; clypeus mid brown. Pronotum light brown; mesonotum mid to dark brown. Forewing hyaline colourless, sometimes with one or more brown marks apically, sometimes with apical third of forewing mid to dark brown apart from a semicircular hyaline area; veins and tubercles concolorous with cells; pterostigma mid brown (basally paler). Legs light brown. Abdominal sternites light, mid or dark brown. Morphology. Body length: ♂ 4.1–4.5 mm, ♀ 4.7–4.9 mm. Head: Vertex 1.8–2.6× wider than long; at level of basal emargination 1.1–1.2× wider than at subapical carina; apical and subapical carina v-shaped; median carina of vertex absent or incomplete (covering 1∕2 of basal compartment of vertex); basal compartment of vertex 0.7–1.3× longer than apical compartment. Frons 1.3× longer than wide; frons only just visible in dorsal view. Position of maximum width of frons more or less around centre of frontoclypeal suture or distinctly distad of frontoclypeal suture. Frontoclypeal suture slightly semicircular, bent upwards, median part not reaching lower margin of antennal scape. Rostrum reaching or slightly surpassing hind coxae; apical segment of rostrum almost as long as subapical segment. Thorax: Pronotum slightly to moderately wider than head (including eyes). Hind margin of pronotum obtusely angled. Forewing 3.3–3.7× longer than wide; forewing with slightly developed basal emargination; costa with about 28–34 tubercles, tubercles concolorous with veins; Sc+R+M near basal cell fused, forming a short (less than half of length of basal cell) common stem Sc+R+M; fork of ScRA+RP distinctly basad of fork CuA1+CuA2; position of r-m distad of fork MA+MP; transverse veinlet M3+4 to Cu1a inserting at M3+4 at same level or basad of r-m; position of icu at CuA at same level or distad of apex of clavus; position of icu at CuP more or less at same level or distant of apex of clavus; RP apically trifid; MA apically trifid; additional subapical cell between branches of MA absent; nodus of y-vein slightly basad of centre of clavus; vein delimiting subapical cell C4 distinctly distad of vein delimiting C5; 10 apical cells. Hind leg: 1st tarsomere with 6 (rarely 5 or 7) apical teeth; 2nd tarsomere with 6 apical teeth. Male genitalia: Anal tube symmetrical in dorsal and caudal view; lateral lobe triangular in lateral view. Ventromedian process of pygofer, triangular, uniformly coloured. Aedeagus: Phallotheca left laterally with long, rounded, curved spine (a) inserting at apex of aedeagus; ventrally with more or less straight spine (b) that is directed caudally; and with long, rounded spine (c). Flagellum unarmed (Löcker 2014).
