Ancylorhynchus oldroydi: Lindner 1961: 3 View in CoL ( Fig. 1 View Fig hypopygium); Oldroyd 1980: 360 (catalogue). Redescription:
Male (based on holotype, but supplemented with information taken from a perfect topotypic ♂ in UZMD [information in square brackets]. Condition: Fair; halteres broken, abdomen almost entirely missing (consumed by dermestids), remaining parts being T1 and parts of T2–4. Type is apparently slightly teneral resulting in colours not being fully developed.).
Head: Dark red-brown [black], silver pruinose, white and black setose. Antenna ( Fig. 16 View Figs 3–30 ): Scape dark red-brown [black] with black macrosetae and fine white setae, pedicel orange [orange-brown] with tiny black setae, postpedicel black, tipped with obliquely situated pit-enclosed spine-like sensory element, terminal stylus ‘segment’ absent. Segmental ratios: 1:0.2:4.6 (i.e. a tiny pedicel and a long postpedicel). Face dark red-brown [black], strongly silver pruinose except for lateral parts of epistomal margin and dorsomedial spot adjacent to antennal sockets, mystax shiny white (U-shaped in anterior view) occupying ventral ½ of face. Frons and vertex dark red-brown [black], fine silver pruinose except for transverse band across frons, white setose; ocellar tubercle fine white setose. Occiput dark red-brown [black], uniformly silver pruinose, black setose except for few white setae dorsally. Palpus orange-brown [dark red-brown], black setose, terminal palpomere swollen, apex with terminal sensory pit. Proboscis brown-orange [orange-brown], white [black] setose.
Thorax: Dark red-brown [black] with some brown-orange areas dorsally [uniformly black], fine silver pruinose (especially mesonotum), black and white. Prothorax entirely dark red-brown [black], fine silver pruinose, mainly black setose (few white). Mesonotum dark red-brown except for orange-brown postpronotal lobes [entirely black], silver pruinose, fine setae white macrosetae black. Mesonotal macrosetae: dc thin black confined to area posterior to transverse suture, c. 3–4 npl, 1–2 spal, 4–5 pal. Scutellum dark red-brown apical margin paler brown [entirely black], fine silver pruinose, disc sparsely black and white setose, hind margin with c. 8 black moderately developed macrosetae accompanied by black and white minor setae. Pleura dark red-brown [black], silver pruinose, setae black and white confined mainly to anepst, kepst and ktg. Anatg and mes pnot dark red-brown [black]. Legs: cx dark red-brown [black], silver pruinose, white setose; tro orange-brown [dark red-brown to black] (tro 2 with row of short black setae ventrally); fem, tib and tar uniformly orange-brown [dark red-brown to black], black and white setose, claws dark red-brown with orange-brown proximal parts. Wings ( Fig. 46 View Figs 41–50 ): 7.6×3.1 [8.5×3.4] mm. Veins orange-brown. Membrane extensively microtrichose (some proximal cells partly bare), cells fairly uniformly pale brown [dark brown], proximal cells transparent. Halteres missing [yellowish with pale brown stalk]. Abdomen: Predominantly yellow-orange [orange] with some dark red-brown [black] parts, silver pruinose, whitish setose. T1 dark red-brown [black] white setose; T2 bright yellow-orange [orange] with dark red-brown [blackish] anterolateral parts and narrow posterolateral margin, strongly silver pruinose posterolaterally, T3–4[7] entirely yellow-orange [orange]; [T8 brown-orange; terminalia dark red-brown to black]. [Sternites fairly similar to tergites, black and white setose].
Genitalia ( Figs 105–107 View Figs 93–110 , Bagamoyo): Epand bifid, forming pair of relatively short lobes. Lobes closely abut proximally, each having slight curved appearance in dorsal view, distal parts fairly slender, inwardly curved. Proct (weakly sclerotised) simple, dorsally situated cerc appearing fused proximally. Goncx well developed, outer lobe tapering to longish slender distal region that projects posteriorly to beyond level reached by epand; dorsal finger-like process completely absent; inner lobe well developed, distal end sclerotised, strongly medially directed (overlapping opposing lobe). Gonst laterally compressed, dorsally directed, tip curved anteriorly (somewhat hidden from view in undissected genitalia). Hypd moderately developed, tapering rapidly to truncate distal end; distal end with pair of diverging, rounded protuberances each with group of setae. Aed (largely hidden in undissected genitalia) with lateral extremities distally and tiny bifid distal tip.
Variation:A fairly consistent species demonstrating a degree of sexual dimorphism. Females have somewhat orange antennae. The mesonotum is orange with a cross-shaped marking which varies in extent. The legs are orange. The wing is mainly yellowish with a dark red-brown tip. Abdominal coloration is variable, tergites being dark red-brown with orange hind margins or extensively orange.

Distribution, phenology and biology: Known from Central ( Zambia) and East Africa ( Tanzania) ( Table 1). The species has been collected in December, February, April and June (Table 2). The biology is unknown, but label data suggest that this is a species inhabiting woodland and savanna biomes.
Similar species: A member of the nomadus species-group with close similarities to prunus .
