Redescription:
Male (based on holotype. Condition: Good; right antenna broken off beyond pedicel; left metathoracic tarsus missing; generally greasy, thus obscuring pruinescence.).
Head: Dark red-brown to black, black and whitish setose.Antenna ( Fig. 19 View Figs 3–30 ): Scape dark red-brown to black, black and white setose (all macrosetae black); pedicel red-brown, tiny white setae only; postpedicel dark red-brown, tipped with obliquely situated pit-enclosed spine-like sensory element (terminal stylus ‘segment’ absent). Segmental ratios: 1:0.2:4.8. Face black, although greasy pruinescence visible except laterally on epistomal margin and small area mediodorsally below antennal sockets, mystax whitish, with inverse U-shape, occupying ventral ⅓ of face. Frons and vertex black, mainly whitish setose (few black setae laterally); ocellar tubercle fine whitish setose. Occiput black, black setose except for few white setae dorsally. Palpus black, black setose, terminal palpomere swollen, apex with terminal sensory pit. Proboscis dark red-brown, dark red-brown setose.
Thorax: Black with red-brown areas dorsally, black and white setose. Prothorax entirely black, mainly black setose (few whitish setae). Mesonotum red-brown with hardly discernible black central marking, fine moderately long white setose. Mesonotal macrosetae (black when present): dc weak black confined to area posterior to transverse suture, c. 3–4 npl, 1 spal, 3–4 pal. Scutellum entirely dark red-brown, disc sparsely black and white setose, hind margin with c. 6 black moderately developed macrosetae accompanied by minor white setae. Pleura entirely dark red-brown, setae white and dark red-brown confined mainly to anepst, kepst and ktg. Anatg and mes pnot dark red-brown. Legs: cx dark red-brown, white setose; tro dark red-brown (tro 2 with row of short black setae ventrally); fem, tib and tar uniformly dark red-brown to black, entirely white to pale yellow setose, claws dark red-brown with slightly paler proximal parts. Wings ( Fig. 49 View Figs 41–50 , allotype): 10.3× 4.3 mm. Veins dark red-brown. Membrane entirely microtrichose, red-brown. Haltere orange with dark brown stalk.
Abdomen: Uniform dark red-brown to blackish, pale yellow to white setose.
Genitalia ( Figs 111–113 View Figs 111–128 ): Epand bifid, forming pair of relatively short and stout lobes that project just beyond other genital structures. Lobes closely abut proximally, each with slightly curved appearance in dorsal view, distal parts inwardly curved. Proct simple, dorsally situated cerc appearing fused proximally. Goncx well developed, outer lobe tapering to fairly narrow, slightly upturned distal end; dorsal finger-like process completely absent; inner lobe well developed, visible in lateral view, distal end well sclerotised, fairly pointed, medially directed. Gonst somewhat laterally compressed, dorsally directed, tip curved anteriorly (partly hidden from view in undissected genitalia). Hypd moderately developed, tapering fairly rapidly to broad truncate, slightly bulbous distal end; distal end fairly weakly sclerotised, slightly inflated laterally. Aed fairly elongate (somewhat hidden in undissected genitalia) with narrowly rounded distal tip. Variation: Female similar to male, greasy except for a few tiny areas that show silver pruinescence.
Holotype (examined): ♂ MOZAMBIQUE: ‘Amatonga Forest [19°10'S: 33°44'E] / Mozambique / D. Cookson / 15.2.64’, ‘ Ancylorrhynchus / prunus sp. n. / det. H. Oldroyd 1971 / Holotype’ (NMSA).
Paratype (examined): ♀ similar data as holotype, but labelled as paratype ( NMSA) .
Distribution, phenology and biology: Known only from the type locality in Southern Africa ( Mozambique) ( Table 1). The species has been collected only in February (Table 2). The biology is unknown, although the locality suggests that this is a forest inhabiting species. While this may not necessarily be true as most species in the genus are not associated with forest undergrowth, but may be found in more open places adjacent to forests, the fact that the species is very darkly coloured (frequently a characteristic associated with forest insects) may support the suggestion that it does indeed actually inhabit forests.
Similar species: A member of the nomadus species-group with close similarities to oldroydi .
