Redescription:

Male (based on holotype. Condition: Good; both antennae broken off beyond pedicels; right prothoracic leg broken off beyond coxa.).

Head: Dark red-brown, silver and gold pruinose, orange and red-brown setose.Antenna ( Fig. 8 View Figs 3–30 ): Scape and pedicel orange, orange and red-brown setose, postpedicel missing (see below for details regarding other specimens). Segmental ratios: 1:0.4:–:–. Face dark red-brown, extensively fine silver-gold pruinose (except lateral parts of epistomal margin and large area below antennal bases), mystax shiny orange and red-brown, occupying ventral ½ of face. Frons and vertex dark red-brown, fine silver-grey pruinose (except for ocellar tubercle), orange and red-brown setose; ocellar tubercle fine red-brown setose (no macrosetae). Occiput dark red-brown, uniformly silver pruinose, orange setose (few red-brown ventrally). Palpus brown-orange setose, terminal palpomere swollen, apex projecting with terminal sensory pit. Proboscis brown-orange, orange setose.

Thorax: Dark red-brown with orange areas dorsally and laterally, fine silver-grey pruinose, red-brown and orange setose. Prothorax dorsally orange, laterally red-brown, fine silver-grey pruinose, orange and red-brown setose. Mesonotum chiefly orange with large centrally situated dark red-brown to black area (all margins orange), fine silver-grey pruinose, fine moderately long yellow-orange and red-brown setose. Mesonotal macrosetae (orange when present): dc red-brown, weak, postsuture, 3 npl, 1 spal, 2 pal. Scutellum entirely orange, fine silver pruinose, disc sparsely red-brown setose, hind margin with 2 orange macrosetae accompanied by 2 minor setae. Pleura extensively dark red-brown (anepm, ktg and anatg brown-orange), entirely fine gold pruinose, setae red-brown (anepst) or brown-orange (ktg). Legs: cx and tro brown-orange (tro 2 with row of short black setae ventrally); fem, tib and tar uniformly orange, mainly red-brown setose, claws dark red-brown with orange proximal parts. Wings ( Fig. 38 View Figs 31–40 ): 6.7× 2.9 mm. Veins yellow-orange. Membrane entirely microtrichose giving wing a uniformly brown colour. Haltere orange-brown with brown-yellow knob.

Abdomen: Predominantly dark red-brown with orange areas, silver pruinose, brownorange-yellow setose. T1 dark red-brown, slightly orange-brown laterally, T2–4 dark red-brown with small orange patches posterolaterally (these areas strongly silver pruinose), T5–8 progressively more orange with silver pruinose hind margins. Sternites fairly uniformly red-brown, silver pruinose, orange and red-brown setose.

Genitalia ( Figs 81–83 View Figs 75–92 ): Epand bifid, forming pair of moderately long lobes. Lobes abut proximally and may be weakly fused, each being fairly straight with slight undulations, distal tips slightly inwardly directed. Proct simple, dorsally situated cerc weakly demarcated and possibly fused proximally. Goncx well developed, fairly broad in lateral view, outer lobe projecting to rounded apex; dorsal finger-like process greatly reduced, appearing as slight setose bump; inner lobe well developed, distal end sclerotised, slightly medially directed (not overlapping opposing lobe). Gonst weakly laterally compressed, dorsally directed, tip curved anteriorly. Hypd moderately developed, relatively short, tapering slightly to broad flattened distal end; distal end in ventral view with pair of broadly rounded protuberances. Aed (somewhat hidden in undissected genitalia) fairly broad, with short distal projection with tiny bifid tip.

Female. Unknown.

Variation: Newly listed material is assigned to this species with some hesitation and primarily on the grounds of male genital similarity. The holotype has a well developed mesonotal marking (being a broad dark red-brown medial band that is wider at the level of the transverse suture) while the other three specimens have a narrow medial mesonotal band that is only slightly darker than the mesonotum and not obviously wider at the level of the transverse suture. Although the holotype is somewhat smaller (wing length 6.7 mm) than the Masiene material (♂ wing 9.1 mm, ♀ 9.2 mm), the BMNH ♂ from the type locality is only slightly larger (wing 7.3 mm). Until more material becomes available I accept the variation in coloration described above as intraspecific.

Holotype (examined): ♂ MOZAMBIQUE:‘Lourenço / Marques.[= Maputo, 25°58'S: 32°34'E] / 19.i.[19]29 / HK Munro’, ‘ Holotype / Ancylorrhynchus / funebris Br’ [red], ‘ Ancylorrhynchus / funebris Broml. / Holotype 156’ [red ink] (NMSA).

Other material examined: MOZAMBIQUE: 1♂ 1♀ ‘ Masiene [16°24'S: 39°54'E] / P.E.Afr / R.F. Lawrence’ ~ ‘ Dec. / 1923’ ( SAMC) GoogleMaps ; 1♂ ‘ Lourenço Marques / 1914 / H.A. Junod / April – July’ ( BMNH) .

Distribution, phenology and biology: Known only from Mozambique ( Table 1). Adults have been collected with some certainty in December–January, while one specimen is labelled April–July thus providing inadequate and suspect information (Table 2). The biology is unknown, but the two known localities are dominated by the Savanna biome. Similar species: A member of the nomadus species-group with close similarities to greatheadi and susurrus .
