Type species: Noabennarella costaricensis sp. nov.

Etymology: The name is an arbitrary combination of letters. Gender: Feminine.

Description

Medium sized cixiids (body length incl. wings in males about 6 mm, females 8.5 mm) with body laterally compressed and wings in resting position steeply inclined ( Figs 1, 2 View FIGURES 1 – 2 , 26 View FIGURES 23 – 26. 23 ).

Frons long and slender ( Figs 10 View FIGURES 7 – 10. 7 , 13 View FIGURES 11 – 15. 11 ), evenly rounded in lateral aspect, without carina on vertex. Hind border straight. Median keel distinct, lateral keels strongly produced, semicircular in lateral view ( Figs 9, 10 View FIGURES 7 – 10. 7 , 13, 14 View FIGURES 11 – 15. 11 ). Median and lateral ocelli distinct. Scapus short, ringlike, pedicellus cylindrical, about 1.5 times as long as wide.

Pronotum short, lateral carinae distinct. Mesonotum with indistinct median and distinct lateral carinae. Fore wings long, slender, surpassing tip of abdomen by half their total length ( Fig. 1 View FIGURES 1 – 2 ). R and MA three­forked, MP bifurcate. Cubital area of the fore wing reduced in favour of the medial area, thus fore wings slightly widened apically ( Fig. 12 View FIGURES 11 – 15. 11 ). Legs very long, metatibiae without macrosetae, apically with 6 spines ( Figs 23, 24 View FIGURES 23 – 26. 23 ). Tarsus with 6+5 apical spines, platellae not present.

Segments four and five with large abdominal processes, bearing 3+2 sensory pits ( Figs 1, 2 View FIGURES 1 – 2 , 3, 5 View FIGURES 3 – 6. 3 ). Two additional sensory pits on 6th abdominal segment.

Male genital and anal segment more or less symmetrical ( Figs 19, 21, 22 View FIGURES 16 – 22. 16 ). Aedeagus with shaft and flagellum well developed, shaft with set of movable spines, flagellum long and slender, in repose bent to the left side ( Figs 16, 17 View FIGURES 16 – 22. 16 ).

Apex of female abdomen truncate, without wax plate. Ovipositor evenly curved, at rest adjacenting to abdomen ( Figs 3, 4 View FIGURES 3 – 6. 3 ). Ductus ejaculatorius wound helix­like, with three windings ( Fig. 25 View FIGURES 23 – 26. 23 ).

Note: We studied one female Noabennarella specimen with a wing coloration distinctly different from that of N. costaricensis . This specimen (see Figs. 3, 4 View FIGURES 3 – 6. 3 , 25, 26 View FIGURES 23 – 26. 23 ) is labelled “ Peru: Monon Valley, Tingo Maria, XI­21­1954 // E.I.Schlinger & E.S.Ross collectors // Amazobenna reticulata ” and stored in the collection of the Californian Academy of Sciences. We do not know if different wing coloration patterns or sexual dimorphism exist within Noabennarella and if this female belongs to N. costaricensis or represents another undescribed species.

Differential diagnosis

Noabennarella can be easily distinguished from other Bennarellini by the shape of the head (especially frons) and its keels and by the venation of the fore wings. In Amazobenna and Bennarella the frons is much broader, and the lateral keels are directed laterally (see Figs 7, 8, 9, 10 View FIGURES 7 – 10. 7 , 13, 14, 15 View FIGURES 11 – 15. 11 ). CuA and MP veins are strongly arched near the apex ( Fig. 12 View FIGURES 11 – 15. 11 ), whereas they are straight in Bennarella , and in Amazobenna only CuA is strongly arched.
