Adelotropis spinosus  nov.sp. ( figs 18, 20, 21View Figs 17-21)

M a t e r i a l e x a m i n e d: Holotypus: (♀) Kortright, Freetown, Sierra Leone, Dec. ́68, D. Owen; ex Myrina silenum ( ZSM, Munich). 

R e m a r k: This species was found in the HEINRICH collection hosted at the Zoologische Staatssammlung Munich as Adelotropis  sp. It differs from A. farquharsoni  WATERSTON and A. gabonense  nov.sp. by its very long central spine of the scutellum and extended reddish color pattern, finer punctures of the face, and the extended ivory coloration of fore and middle legs.

D e s c r i p t i o n: ♀: Body length 9 mm. Flagellum with 25 flagellomeres, short, filiform; 1 st flagellomere 1.8x longer than wide, 2 nd flagellomere 2.3x longer than wide and 1.3x longer than the 1 st flagellomere, combined length 0.5x eye length. Head transverse, temples moderately narrowed behind eyes, c.0.6x as wide as the eye. Distance of lateral ocellus to eye c.1.6x its diameter. Frons with fine punctures, smooth medially; temple with very scattered and fine punctures. Face and clypeus with fine dense punctures, epistoma rugose-punctate. Apical margin of clypeus slightly concave. Malar space 1.15x longer than the width of mandibular base. Gena with scattered superficial punctures ventrally. Genal carina reaching the mandibular base. Mandible very large and wide, with wide gap between the teeth; lower tooth wider but shorter than the upper one. Mesosoma with pale hairs. Epomia moderately strong. Side of pronotum with punctures dorsally and distinct striation centrally and ventrally. Mesoscutum with dense coarse punctures, shining; notaulus distinctly impressed in frontal 0.2. Subtegular ridge sharp. Mesopleuron densely rugose-punctate, speculum finely granulate, matte. Sternauli distinctly impressed in frontal 0.4 of mesopleuron, with fine transversal ribs; epicnemial carina narrow, reaching the frontal margin of mesopleuron. Scutellum about as long as wide, with complete lateral carina, surface with some coarse rugae and a long central spine. Propodeum and metapleuron with very coarse reticulo-rugose punctures. Juxtacoxal carina partly present. Propodeal spiracle oval, c.2x longer than wide. Area basalis trapezoid, wider than long. Area superomedia sickle-shaped, 2.6x wider than long, costula reaching the area petiolaris shortly behind the area superomedia. Area petiolaris very strongly impressed medially, without lateral carina, coarsely rugose. Hind coxa with dense coarse punctures, without scopa. Hind femur coarsely rugose-punctate, smooth

ventrally, c.3.5x longer than wide. Claws with some fine basal pecten. Areolet pentagonal, frontal distance of intercubiti c.4x their width, 2nd recurrent vein

slightly distal to its middle; nervulus antefurcal by 2x its width; nervellus of hind wing intercepted in its apical 0.75.

Metasoma amblypygous, short-oval. Petiolus slightly wider than high; postpetiolus strongly widened, without dorsal carina, but slightly elevated median field, completely rugose-punctate. Gastrocoelus rectangularly impressed, with longitudinal ridges. Thyridium transverse, c.0.75x as wide as the interval. 2 nd tergite 1.7x wider than long, 3 rd tergite 2.4x wider than long; both tergites with coarse and dense rugose-punctures, structure slightly smooth on 3 rd tergite centrally; following tergites with smooth surface and scattered fine hair-punctures. Ovipositor sheath not surpassing the metasomal apex.

Color: Head and mesosoma reddish, propleuron and mesosternum blackish. Metasoma reddish-brown, darker brownish medially. Flagellum brown, more or less yellowish ventrally. Ivory areas are located on: mandibular base, frontal orbit, postscutellum, fore and middle coxae completely, hind coxa except black spots on lateral and medial sides, fore and middle femora apico-frontally, fore and middle tibiae frontally and large apical spots on 4 th to 7 th tergites. Legs dark chestnut-brown. Wings hyaline, pterostigma dark brown.

Male unknown.

H o s t: Myrina silenum (FABRICIUS, 1775) (Lep., Lycaenidae  ) (ZSM).
