description: Madoxychara gen. nov.
(Figs 1–52)
Type species: Madoxychara unicornis sp. nov., here designated.
Etymology. The generic name is a combination of two words: Madagascar and Paroxychara, the African flatid genus which is closely related to Madoxychara gen. nov. Gender: feminine.
Diagnosis. Madoxychara gen. nov. is externally similar to genus Paroxychara Lallemand et Synave, 1952 but differs by the following genital characters: male—anal tube elongated and ‘broken’ at midlength, basal part of periandrium with 3 narrow and elongated dorsal processes oriented apicad, aedeagus single (not symmetrical) (Paroxychara —anal tube short and widened, basal part of periandrium without processes, aedeagus symmetrical); female—posterior margin of gonoplac with single tooth, base of gonapophysis VIII with narrow and long appendage (Paroxychara —posterior margin of gonoplac with 6 teeth, base of gonapophysis VIII without appendage).
Description. Body slender. Head strongly prolonged, with compound eyes in dorsal view distinctly narrower than thorax (Figs 1, 3, 5, 6).
HEAD. Vertex a bit wider than long at midline, not covered by pronotum (Figs 3, 7, 8); posterior and lateral margins carinate, anterior margin obsolete. Disc of vertex almost flat, with carina placed in median groove (Figs 7, 8). Disc of vertex, pronotum and mesonotum without sensory structures and secretory pores. Occiput not visible on upper part of head. Frons longer than wide (in frontal view), widest about level of antennae (Figs 4, 11, 12); disc of frons convex, smooth, without carinae; lateral margins of frons carinate with breaking point at about level of antennae. Frons with protrusion in upper part; apex of protrusion (in lateral view) at about same level as thorax (Figs 2, 10); margin of frons (in dorsal view) bluntly rounded; upper surface depressed, without carinae and distinctly longer than vertex in dorsal view (Fig. 8). Compound eye (in dorsal view) oval, posterior margin reaching midlength of pronotum; eyes with small callus at posterior margin (Figs 9, 10). Pedicel about as long as wide at apex, with setae and plate organs present apically (Figs 13–16). Clypeus narrower than frons, without median and lateral carinae (Figs 4, 11, 12). Rostrum with apical segment distinctly shorter than subapical one, its apex reaching hind coxae.
THORAX. Pronotum longer than vertex at midline; disc of pronotum with short, weakly visible carina placed in median groove; postocular eminences triangular (Figs 3, 7, 9). Mesonotum triangular; disc tricarinate, carinae separated at base; median carina reaching scutellum, lateral carinae sinuate, reaching posterior margin; median portion between lateral carinae depressed (Figs 7, 9).
Tegmen (Figs 17–19) elongate, coriaceous and convex with well visible venation and small bulla. Costal margin strongly arcuate, meeting postclaval sutural margin at acute angle; postclaval sutural margin straight and extended. Costal area without lobe at base; costal area about same width of its length, narrower than costal cell, with transverse veinlets; apex of costal area a bit before end of clavus. Costal cell wider than costal area, tapering apicad, with transverse veinlets in distal part. Basal cell longer than wide. Longitudinal veins Sc+R arises as short common stem from basal cell with first fork before bulla; Sc+RA runing over bulla and forking just before margin; RP passing-by bulla and forking before wing midlength; RP 1+2 and RP 3+4 single; M fork before end of clavus, at the level of Sc+RA fork; Cu bifurcate after end of clavus. Tegmen with irregular net of transverse veinlets in apical part, without nodal line and with single and short apical line; basal part of longitudinal veins without veinlets. Claval veins Pcu and A1 fused distinctly after half of clavus length, vein A1 elevated; transverse veinlets absent. Tubercles (sensory and wax gland-plates) on whole tegmen with concentration on costal area, between basal Sc+RA and M veins and on clavus between PCu and A1.
Hind wings distinctly shorter than tegmina, reaching about half of abdomen, transverse veinlets absent.
Fore and middle femora slightly shorter than tibiae, subrectangular in cross section. Hind femur distinctly shorter than tibia; hind tibia arcuate and flattened laterally with 2 lateral spines placed near apex, apically with row of 8 well developed teeth (Figs 20, 21); tarsomeres about same length; basitarsomere with 4 apical spines in formula 2+2 (lateral larger than internal) separated by oval pad of sensory structures (Figs 21, 22); second tarsomere with 2 well developed lateral spines, median lobe exceeding level of spines (Fig. 21).
MALE GENITALIA. Anal tube (in lateral view, Figs 23, 24) elongated, almost same width, strongly ‘broken’ near base of anus; anus placed about midlength. Anal tube (in dorsal view, Fig. 25) elongated, basal part a bit wider than apical part, lateral margins of basal part concave; anus placed about midlength. Pygofer (in lateral view, Figs 23, 24, 26) higher than wide; dorsal part narrower than ventral part, dorso-posterior angle bluntly rounded, without processes; posterior margin weakly arcuate; ventro-posterior margin with shallow incision. Genital styles (in lateral view, Figs 24, 35) longer than wide and bearing distinct, narrow and sharp capitulum; dorsal margin without concavity near base of capitulum; dorsal and ventral margins almost parallel, ventral part of posterior margin projected. Phallic complex. Periandrium tapering apicad, in cross section V-shaped (Figs 36, 38); basal part well developed with 3 narrow and elongated dorsal processes oriented apicad; lateral processes longer than median (Figs 36, 37), in specimens (333) from Zombitse median process reduced with small lobe at the base margin (Figs 38, 39). Periandrium closed basally to about 1/3 length, open dorsally; without additional structures (Fig. 40). Aedeagus s.s. in form of single arm, long and slender, apically with horn-like appendage (Figs 41, 42).
FEMALE GENITALIA. Pregenital sternite (Figs 31, 43) with well developed lateral lobes; anterior margin in median portion convex, posterior margin deeply concave, medially almost straight. Anal tube (in lateral view, Figs 27, 28, 44) not exceeding posterior margin of gonoplac, elongated, tapering apicad, anus placed before midlength. Anal tube (in dorsal view, Fig. 45) elongated, lateral margins almost parallel, apical margin rounded, anus placed before midlength. Gonoplac unilobate (Figs 29, 30, 46), rounded and well sclerotised, without membranous part; posterior margin with long setae and single, small tooth placed in lower part; internal side along posterior margin with dense and short setae.
Gonapophysis VIII (Fig. 47) flat, oriented vertically, apical part widened with 4 big obtuse teeth at posterior margin; base with narrow and long appendage oriented ventrad (Figs 32–34); endogonocoxal process as long as gonapophysis with spiniferous microsculpure. Gonaphophyses IX and gonospiculum bridge as in Figs 48–49. Bursa copulatrix of single pouch, rounded (Fig. 50); cells with sclerotised plates cover ¾ of pouch, except from base. Spermatheca well developed (Fig. 51); ductus receptaculi basally ribbed, about same width; diverticulum ductus smooth, about same length as ductus receptaculi.
Distribution. Madagascar: Antananarivo, Fianarantsoa and Toliara provinces (Fig. 52).
