Diagnosis The body flattened somewhat laterally. Head elongated, with fastigium developed, lateral margins of frons carinate, undulating, prolonged on postclypeus; lateral carinae of postclypeus converging ventrad, but not connected, not prolonged on anteclypeus; anteclypeus about three times as long as wide, elongated oval, with median carina not reaching its apex, wedged in between lora; clypellus triangularly elongate, acute, about half as long as anteclypeus; lora well visible in anteroventral view; antennal pedicel subglobose, with plate organs star-like with dichotomic arms, present on whole surface of pedicel. Pronotum wider than head with compound eyes, with disc elevated, with median carina and parallel lateral carinae, not reaching posterior margin, disc with lateral pits; lateral portion of pronotum declivous with 4 incomplete ridges in posterior portion, and two postocular carinae. Mesonotum wider than long, with median and lateral carinae, obsoletely reaching posterior margin, mesoscutellum separated. Tegmen elongate, with longitudinal veins on corium and clavus carinate, ‘frosted’ on the membrane; stem ScP+R forked in basad ¼ of tegmen length, stem MP forked beyond the apex of clavus, stem CuA forked apicad of claval veins junction, terminals of CuA reaching margin on tornus. Corium slightly more sclerotized than membrane. Cell C3 short, less than ¼ of C1 length. Appendix distinct, tornus very long, almost straight. Hind wing with single RP and MP, cell C5 wide, intersected by median fold; cubital fold posteriorly diverging from CuP; anal lobe rounded. Profemora with a double row of ventral short, stout setae. Metafemur with the lateral cuticular spine in basal half, with 10 apical teeth, basimetatarsus and midmetatarsus with 10 apical teeth, with subapical cuneiform platellae, viz. metatibiotarsal formula 10: 10(8): 10(8). Male medioventral projection of pygofer unilobate; suspensorium circular; male genital styles with dorsad and mediad processes at the base and bilobate projection near the middle. Ventral lobes of periandrium with two cephalad projections near the base. Aedeagus with apical portion more sclerotized, forming a ‘fang’ with apices directed laterad. Female anal tube (segment XI), in lateral view, reaching posterior margin of gonoplac. Posterodorsal part of gonoplac with numerous setae (bristles). Anterior connective lamina (ACL) with 2 sclerotized arms and apical teeth. The base of the bursa copulatrix pouch with single sclerite. Etymology The generic name is derived from the Classic Greek ‘plectos’ (πλεκτός, plektós) meaning ‘woven’ and the generic name Achilus . Gender: masculine. Distribution Western Cape Province , Republic of Southern Africa. Composition Only the type species is known so far.
