Taxonomic note

The Melichar monograph is divided into two parts; in the first part ( Melichar 1901) the genus Urana is placed in the genera key section and marked as “gen. n.”, in the second part ( Melichar 1902) the full descriptions of the genus and species are given. Gender: feminine.

Type species

Urana paradoxa Melichar, 1902 View in CoL , designated by monotypy.

Diagnosis

Differs from other Afrotropical genera of Selizini by the following external characters: frons with Y-shaped median carina, disc of mesonotum with four gibbosities.

Ocelli present but weakly visible. Clypeus narrower than frons, without carinae; disc of clypeus in median portion convex ( Figures 1E View Figure 1 ; 2G,H View Figure 2 ). Rostrum reaching between hind coxae, apical segment shorter than subapical ( Figure 1C View Figure 1 ).

Thorax. Pronotum distinctly longer than vertex in midline; anterior margin elevated, arcuate, in median portion partly flattened, posterior margin shallowly concave; disc of pronotum with median and lateral carinae; median carina weakly visible reaching to posterior margin, from half of length within groove formed by lateral and arcuate ridges connected with posterior margin; lateral carinae clearly visible, obsolete near anterior margin, disc between carinae and ridges strongly depressed; lateral parts of disc with crest (postocular eminence) ( Figures 1D View Figure 1 ; 2B,C,E View Figure 2 ).

Mesonotum deltoid, longer than cumulative length of vertex and pronotum at midline. Disc of mesonotum with lateral carinae connected at base reaching to posterior margin, median carina absent; disc of mesonotum between lateral carinae flattened with distinct and high gibbosities placed in anterio-lateral part; disc outside lateral carinae with bluntly rounded small gibbosities near posterior margin ( Figures 1B,D View Figure 1 ; 2A–D View Figure 2 ).

Whole tegmen with dense net of transverse veinlets, without nodal line and with three apical lines. Tegmen elongated; costal margin in posterior one-third weakly arcuate, almost straight (not sinuate) before apex, costal angle rounded, just after level of sutural angle, apical and postclaval margin convex ( Figures 1A View Figure 1 ; 2A,C,D View Figure 2 ; 3D–F View Figure 3 ). Costal area short, parallel-sided, with dense transverse veinlets, ending at the level of fusion of claval veins. Costal cell much wider than costal area, tapering distally, with apex at same level as costal area. Basal cell much longer than wide. Tegmen with two longitudinal veins Sc+R and M arising as short common stem from basal cell, Sc+R fork at top of bulla, Sc+RA fork at level of M fork, RA single with dense transverse veinlets between the vein and costal margin, RP single; M forked distinctly basad of Cu fork, M 1+2 forked at the level of apical line, ending with six to eight terminals, M 3+4 forked just after distal end of clavus, ending with five to eight terminals; CuA bifurcated at about apex of costal area, CuA 1 with three terminals, CuA 2 with two or three terminals. Apical cells subrectangular, subapical cells short and almost quadrate, third row of cells quadrate, shorter than subapical cells. Sensory and wax gland-plates dispersed on tegmen ( Figure 3D–H View Figure 3 ). Clavus with strongly elevated base of A 1 vein; Pcu weakly elevated, sinuate, fused with A 1 after half of clavus length; transverse veinlets present between CuP – Pcu and Pcu – A 1 ( Figures 1A View Figure 1 ; 2A–D View Figure 2 ; 3E,F View Figure 3 ).

Fore and middle femora slightly shorter than tibiae, subrectangular in crosssection; tibiae almost square in cross-section. Hind femora distinctly shorter than tibiae; tibiae arcuate with two lateral spines in distal half, with row of eight big apical teeth, lateral teeth much longer than median; basitarsomere longer than cumulative length of second and third tarsomeres, with five or six apical spines; second tarsomere with two well-developed lateral spines, median portion not exceeding the level of spines ( Figures 4A–C View Figure 4 ).

Male genitalia. Anal tube (in lateral view, Figures 5C View Figure 5 ; 6B View Figure 6 ) elongated, with maximum width near midlength, tapering apically; anus placed about middle of anal tube length. Anal tube (in dorsal view, Figures 5D View Figure 5 ; 6A View Figure 6 ) elongated, basal part distinctly narrower than median part.

Pygofer (lateral view) higher than wide; about the same width at dorsal and ventral part, dorso-posterior angle bluntly rounded, without processes; posterior margin weakly arcuate.

Genital styles (lateral view, Figures 5E View Figure 5 ; 6C View Figure 6 ) longer than wide and bearing distinct, narrow and sharp capitulum; dorsal margin without concavity near the base of the capitulum; dorsal and ventral margins almost parallel; internal margin of capitulum with bluntly angled process at about middle of height.

Phallic complex. Periandrium ( Figures 5A,B View Figure 5 ; 6D,E View Figure 6 ) closed basally, dorsally open; ventral part with elongated lobes. Basal part with teeth, dorsal periandrium medially with small teeth, apically with elongated process.

Aedeagus s.s. divided by long lateral split into dorsal and ventral part; ventral part apically bilobate; dorsal part a bit longer than ventral, with lateral and apical lobes.

Female genitalia. Pregenital sternite with huge lateral lobes, weakly separated from median part; anterior margin weakly concave, posterior margin convex, flattened in median portion and covered by additional narrow lobe; margin of lobe convex with flattened median portion and medially small incision. Lateral lobes with straight and subparallel margins, anterior margin convex, posterior margin almost straight. Disc of sternite in median portion slightly elevated ( Figures 4D,G,H View Figure 4 ; 7A View Figure 7 ).

Anal tube reaching end of gonoplac and completely covering gonoplac. Anal tube, in lateral view, narrow with parallel dorsal and ventral margins ( Figure 4D View Figure 4 ). Anal tube, in dorsal view, elongately pear-shaped with shallow incision apically. Anus placed at about midlength of anal tube length. Surface and margins of anal tube almost without setae ( Figures 4E View Figure 4 ; 7B View Figure 7 ).

Gonoplac unilobate, extremely narrow and elongated with parallel margins; posterior margin with row of four to seven well-developed teeth; narrow membranous part placed alongside ventral margin ( Figures 4D View Figure 4 ; 7C,D View Figure 7 ).

Gonaphophysis VIII sabre-shaped, tapering apicad and laterally flattened; apical part of ventral margin folded, apical part of dorsal margin with single tooth. Endogonocoxal process a bit shorter than gonaphophysis VIII, sabre-shaped with spiniferous microsculpture, tapering apicad ( Figures 4D,F View Figure 4 ; 7E View Figure 7 ).

Spermatheca well developed; ductus receptaculi in half ribbed and widened; diverticulum ductus shorter than ductus receptaculi, anterior part tubular, posterior part in the form of elongated and membranous bulla.

Coloration. General body colour ochraceous with orange tinge and dark brown or black patches on pronotum, mesonotum and tegmina; frons orange with milky white dots, two dark patches above frontoclypeal suture; legs ochraceous; abdominal sternites yellowish to brownish, lateral parts of tergites dark brown to black with yellow apical and posterior margins; genital capsule yellowish to brownish.
