Soares gen. nov.

( Figs. 1–53 )

Type species. Soares testudinarius gen. et sp. nov., here designated.

Etymology. The generic name refers to Diogo Soares , a 16th-century Portuguese navigator and explorer who visited the northern coastal part of Madagascar in 1543 (presently Diego-Suarez Bay). Gender: masculine (Genetivus singularis: Soaresis).

Diagnosis. Soares gen. nov. differs from other Afrotropical Phantiini by the following characters: rostrum surpassing half of abdomen; vertex, pronotum and mesonotum with median groove limited laterally by the ridges; Cu veins forming elongate cell with 2 transverse veinlets; postclaval margin of tegmen very short without CuA terminals.

Description. Body robust. Head with compound eyes (in dorsal view) distinctly narrower than thorax ( Figs. 1–3 ).

HEAD. Vertex wider than long in mid line, deltoid, not covered by pronotum ( Figs. 1–3 , 9–15 ); posterior margin formed as suture, anterior and lateral margins carinated. Disc of vertex flat, without median carina but with median groove, limited laterally by ridges ( Figs. 1–3 , 10–15 ). Disc of vertex, pronotum and mesonotum covered with single, organized sensory structures and secretory pores ( Figs. 16–17 ). Occiput well visible on upper part of head ( Figs. 13–14 ).

Frons elongated; at upper margin shorter than long in mid line, the widest about level of lower margin of compound eyes, same width (or little wider) as its length in midline; upper margin (in frontal view) convex; lateral margins carinate, at upper portion subparallel and partly concave, with breaking point at about the lower margin of compound eye, lower portion curved towards frontoclypeal suture ( Figs. 4–5 , 22–25 ). Disc of frons smooth with upper part elevated and lower portion weakly concave; median carina absent, lateral carinae arcuate, surpassing half of length of frons and connected at base, in the upper protruded part obsolete ( Figs. 4–5 , 22–25 ).

Compound eye rounded with small callus at posterior margin. Ocelli absent ( Figs. 6 , 11–15 , 21 ).

Pedicel elongate, with setae and plate organs present apically and on upper surface ( Figs. 18–20 ).

Clypeus narrower than frons, without median and lateral carinae ( Figs. 4–5 , 7 , 22–25 ).

Rostrum with apical segment distinctly shorter than subapical one, its apex surpassing the half of abdomen ( Figs. 7 , 24, 26 ).

THORAX. Pronotum longer than vertex in mid line; disc of pronotum with median groove limited laterally by ridges and with short median carina in its posterior portion. Posterior part of pronotum and its margin elevated, median part of disc separated from lateral parts by elongated and laterally carinate deep depressions ( Figs. 1–3 , 10– 15 ).

Mesonotum triangular, longer than cumulative length of vertex and pronotum in midline. Disc of mesonotum with median groove limited laterally by the ridges; lateral carinae distinctly visible, arcuate, separated at base and reaching posterior margin ( Figs. 1–3 , 10–13 ).

Tegmen ( Figs. 1–2, 6 , 9, 11 , 27–32 ) elongate, coriaceous and convex with well visible venation, without bulla and elevated claval veins. Costal margin almost straight, costal and sutural angles broadly rounded, continuous with convex apical margin, with breaking point about the middle of length, both angles at about same level; postclaval margin very short without CuA terminals.

Costal area lobate at base, basal margin of lobe surpassing base of costal cell and clavus; costal area about same width of its length, wider than costal cell and with dense transverse veinlets; apex of costal area surpassing level of sutural angle.

Costal cell narrower than costal area, about same width of its length, with dense transverse veinlets. Basal cell longer than wide.

Longitudinal veins Sc+R arises as short common stem from basal cell, M vein forked a little distad of Sc+R vein, CuA forked distinctly distad of M fork. Tegmen with irregular net of transverse veinlets, without nodal line and with single apical line forming an apical row of square/subrectangular cells; basal part of longitudinal veins without veinlets.

CuA veins after the first fork forming elongate cell with 2 transverse veinlets.

Claval veins Pcu and A1 fused distinctly after half of clavus length; transverse veinlets present between CuP – Pcu and Pcu+A1 – CuP.

Hind wings distinctly shorter than tegmina, reaching about the half of abdomen, with obsolete pattern venation ( Figs. 33–34 ).

Fore and middle femur about as long as tibiae, both partly laterally flattened, subrectangular in cross section.

Hind femur shorter than tibia; hind tibia with single lateral spine placed a little after half of length, apically with a row of 4 big teeth in formula 2+2 and with median diastemma; basitarsomere longer than cumulative length of the second and third tarsomeres, with 4 apical spines in formula 2+2 and with median diastemma; second tarsomere with 2 well developed lateral spines, median portion not exceeding the level of spines ( Figs. 35–38 ).

Male genitalia. Male unknown.

Female genitalia ( Figs. 7–8 , 24 , 39–53 ). Pregenital sternite with well developed lateral lobes; lateral margin of lobes with small incisions; anterior margin almost straight, posterior margin concave and covered by plate-like lobe.

Anal tube twice longer than gonoplac, completely covering gonoplac, heart-shaped in dorsal view, with shallow incision at the top; ventral surface of anal tube covered with long and dense setae; anus placed at half of anal tube length. Anal tube in lateral view oval; ventral margin strongly arcuate, posterior part tapering apicad.

Gonaphophysis VIII L-shaped in cross section; vertical part in lateral view tapering apicad, with teeth at upper margin; horizontal part oriented externally with well developed teeth in apical portion. Gonoplac unilobate, almost rectangular; posterior margin with seven, well developed, big teeth; membranous part placed at distal half of lower margin; median portion of gonoplac weakly convex, with sensory and wax glands.

Gonaphophyses IX and gonospiculum bridge as in Figs. 51–52 .

Bursa copulatrix of single pouch, elongated, without cells but with pores. Spermatheca well developed; ductus receptaculi ribbed and widened in distal part; diverticulum ductus longer than ductus receptaculi, 3/4 of its length ribbed, the rest in the form of elongated, narrow and membranous bulla.

Distribution. Madagascar.
