Treatment

Afrochaetopodella subgen. n.

( Figs 13–26 View Figs 13–18 View Figs 19–26 )

Type species: Chaetopodella reducta sp. n. (here designated).

Gender: feminine.

Other species included: Ch. keniaca sp. n.

In a number of characteristics it is similar to the nominate subgenus. The most important differences are as follow (most of them are synapomorphies): All inter-frontal setae short. Anterior fronto-orbital seta minute. Mid trochanter with a lateral seta, which is shorter than trochanter. Wings clear but not milky. Costal setae between veins H and R 1 short, much shorter than width of costal cell. Discal cell narrow and very long. Abdomen (preabdomen) very long, male sternite 5 with a pair of 3-lobed caudal processes ( Figs 14–15 View Figs 13–18 , 20–21 View Figs 19–26 ). Subepandrial sclerite without strong thorn-like setae ( Fig. 24 View Figs 19–26 ) (that must be a reduction, i.e. a synapomorphy). Male genitalia small. Postgonites robust with several edges or tips ( Figs 17 View Figs 13–18 , 25 View Figs 19–26 ).

The subgeneric name refers to the distribution of the two species presently included.

PAPP L. [Lujza] [abdomen and genitalia in a plastic microvial with glycerol].

Measurements in mm: body length 1.54, wing length 1.32, wing width 0.47. talia), lateral view. Scale: 0.1 mm

Head with anterior 1/3 of frons yellow, other frons dark brown. Face whitish yellow, gena yellow. Three pairs of short interfrontals. Antenna dark brown, incl. scape. Arista 0.58 mm long. Vibrissa strong. Genal setae sparse but comparatively long.

Mesonotum microtrichose dark brown with one sagittal and two dorsocentral stripes less microtrichose, i.e. more shiny. Postpronotum, lateral half of notopleura and a small supra-alar area yellowish. Pleura lighter than mesonotum, particularly so for ventral edges of anepisternum, anepimeron and metapleural parts. Three pairs of dorsocentrals, shortening anteriorad. Scutellum 0.24 mm long, 0.31 mm wide, lateral scutellars 0.27 mm, apical scutellars 0.47 mm long. Posterior katepisternal seta 0.22 mm long.

Wing 2.79 times longer than broad. Wing brownish, veins light brown, including costa. Microcilia of membrane rather strong. Strong subbasal seta on costa only 0.115 mm long. Setae on first costal section only 0.03 mm long. Discal cell with a distinct small caudal vein appendage. R-M – dM-Cu: dM-Cu = 19.5/6 = 3.25. Halter white.

Legs ochreous, only tarsi darker (brown). Lateral seta of mid trochanter 0.10 mm.

Male sternite 5 comparatively long but not broad ( Fig. 14 View Figs 13–18 ), its caudal pair of processes large three-lobed fork, the medial one being the longest, lateral process with 3 long setae ( Fig. 15 View Figs 13–18 ). No extremely long setae on sternite 5. Right part of the syntergosternite 6–8 (tergite 7 and a part of sternite 6) forms a narrow but long re-curved sclerotized process; dorsal part of the syntergosternite large, left lateral and ventral parts almost completely segregated ( Fig. 13 View Figs 13–18 ). Surstylus ( Fig. 16 View Figs 13–18 ) rather compact in two lobes with a number of processes but with only 1 long setae. Postgonite ( Fig. 17 View Figs 13–18 ) thick, medium-long with blunt apex and small swellings dorsally. Apical part of the dorsal process of distiphallus ( Fig. 18 View Figs 13–18 ) with blunt, rather short fork apically.
