(Fig. 2)
Diagnosis. Black overall with pale yellow markings on head, mesosoma and apical margins of tergites; head shining, sparsely to densely punctate on smooth background except clypeus nearly smooth; apical margin of clypeus convex, hardly to distinctly notched medially; antenna with 27–29 flagellomeres; mesosoma and metasoma remarkably deeply and very densely punctate, except ventral half of pronotum coarsely striate, and speculum and scuto-scutellar groove smooth; notaulus indistinct; anterior transverse of carina entirely lacking; ovipositor relatively short.
Differential diagnosis. Differentiated from most of the other Afrotropical Lycorina species by the overall black colour and the deep and close punctation on mesosoma and metasoma; very close to L. yui, L. horstmanni has a more expanded pale colour, and definitively smaller OT and MD (> 1.6 and>1.0, respectively, in L. yui).
Description. Female (2 specimens). B 5.9–6.9; A 4.8–5.1; F 4.7–5.4; MD 0.4–0.5; OT 1.2–1.3.
Colour. Black overall with pale yellow parts: orbits, clypeus, mandible, dorsal margin of pronotum, tegula, and apical margin of tergites; legs orange except coxae dark reddish to black and variably pale yellow maculated; flagellum and ovipositor sheath testaceous, variably infuscate; wings hyaline, slightly infuscate apically, venation yellowish.
Head. Transverse in dorsal view, temple constricted behind eye; temple and vertex sparsely and finely punctate, punctation denser between ocelli; frons and face more densely punctate, background smooth and shining; clypeus almost smooth, very superficially punctate, ventral margin convex, hardly to distinctly notched medially; antenna with 27–29 flagellomeres.
Mesosoma. Pronotum coarsely striate ventrally, deeply and densely punctate dorsally; remainder of mesosoma closely and remarkably deeply punctate, except speculum and scuto-scutellar groove smooth; epicnemial carina reaching half height of mesopleuron; notaulus indistinct; propodeum with anterior transverse carina totally absent, in profile abruptly subdivided by the strong apical transverse carina into horizontal anterior and vertical posterior parts.
Metasoma. Entirely densely, coarsely and remarkably deeply punctate, except oblique impressions costulate; ovipositor relatively short, straight to slightly down-curved.
Male (3 specimens). B 6.1–6.4; A 5.0–5.1; F 5.1–5.4. Face extensively pale yellow; otherwise similar to female.
Etymology. A respectful farewell to Klaus Horstmann, co-author of the Taxapad database, who devoted his life to Ichneumonidae. Danke sehr, Herr Horstmann. The specific epithet horstmanni is in the genitive case.
Distribution. South Africa.
