DESCRIPTION
Body 9.25­11.90 mm in length, 5.04­6.59 mm in width, from yellowish brown to almost black, sometimes corium slightly paler than pronotum and scutellum.
Head dorsally at first sight looking impunctate, but bearing hardly visible tiny punctures, lateral parts of paraclypei wrinkled; clypeus subapically without setigerous punctures, each paraclypeus submarginally with 2­4 setigerous puncture bearing long hair­like setae (Fig. 279); ocular index 2.10­2.64; interocellar index 4.0­8.5; length of antennal segments (in mm): 0.34­0.63: 0.59­0.76: 0.73­ 0.85: 0.90­1.13: 0.94­1.15.
Puncturation of pronotal disc more or less dense, punctures small, clearly visible; calli, umbones and posterior fourth of pronotal disc impunctate; discal transverse impression behind calli shallow, developed only laterally, usually acompanied by a row of coarse punctures; lateral margins of pronotum with 6­8 submarginal setigerous punctures bearing long hair­like setae (Fig. 279). Anterior convexity of propleuron apically punctate with small punctures, posterior convexity distinctly anteriorly punctate with large punctures, propleural depression with a band of coarse punctures and wrinkles.
Scutellar disc punctate with almost evenly spaced punctures.
Corium densely punctate; clavus with one complete and two partial rows of punctures; mesocorial disc densely and almost evenly punctate; exocorium densely punctate; costa flattened, basally expanded, separated from exocorium only in its basal half, costal margin with 2 setigerous punctures bearing long hair­like setae (Fig. 279).
Male mid femur with a row of small teeth; male hind femur with a row of well visible teeth and denticles on margins, subbasal and subapical teeth large (variability of edentation was presented by LINNAVUORI, 1993), male hind tibia with a row of numerous denticles; female hind femur with small (sometimes indistinct) subapical tooth, female tibia simple.
Abdominal sterna more or less polished, punctate only around spiracles and trichobothria.
Male genitalia as in Figs 280­282.

REMARK
The type material of Macroscytus reflexus from South Africa was not found in the collections containing SIGNORET ̕s specimens (it was apparently lost or destroyed). Since the other three species (Macroscytus acutus, M. excavatus, M. inermipes) are found to be conspecific with the former, it was necessary to designate a neotype for M. reflexus.
