( Figs. 4 View FIGURE 4. a – b , 6f View FIGURE 6. a – g , 7 View FIGURE 7. a – b f, 11g –h, 12d, 13f, 14e, 15)
Type species. Foenus ruficornis Spinola, 1851 .
Etymology. I choose the name of this genus in honor of Massimiliano Spinola, because he described the only known species included in the genus. The gender is masculine.
Description. Body length between 14.0–18.0 mm (exclusive of ovipositor).
Head. Subrectangular in dorsal view ( Fig. 11 View FIGURE 11 g); mandible in frontal view with apex acute; malar space long, fused with gena ( Fig. 11 View FIGURE 11 h); clypeus with a longitudinal ridge ( Fig. 6f View FIGURE 6. a – g ); clypeus and face without longitudinal striae; occipital margin crenulate ( Fig. 11 View FIGURE 11 g).
Mesosoma. Propleuron simple anteriorly; mesonotum truncate in lateral view ( Fig. 13 View FIGURE 13 f); mesoscutum uniformly sculptured, longer than wide, and almost forming a unique plane with two lobes separated by depressed notauli ( Fig. 12 View FIGURE 12 d); parapsides barely visible; mesepimeron with a dorsal ridge ( Fig. 13 View FIGURE 13 f); fore and middle tibiae uniformly colored; hind tibia red brown, with apex black; metacoxa areolate at posterior portion ( Fig. 14 View FIGURE 14 e); propodeum not carinate, with median longitudinal axis slightly concave ( Fig. 14 View FIGURE 14 e); fore wing jugal lobe present; discal cell present, subtriangular ( Fig. 7 View FIGURE 7. a – b f), vein r–m present; vein 2–M tubular in 1st 1/3 and spectral in remaining portion ( Fig. 4a View FIGURE 4. a – b ); hind wing with 4–6 equidistant hamuli ( Fig. 4a View FIGURE 4. a – b ); pronotum with three lobes well defined; pronotal process absent ( Fig. 13 View FIGURE 13 f).
Metasoma. First metasomal tergum with edges separate, not concealing 1st sternum; female subgenital sternum with a slitlike Y-shaped notch (as Fig. 10 View FIGURE 10 a); ovipositor longer than T2+T3 and shorter than metasoma ( Fig. 4 View FIGURE 4. a – b ).
Distribution. The only species occurs in central Chile between 28ºS and 35ºS ( Fig. 15 View FIGURE 15 ), an area characterized by a Mediterranean climate. Unfortunately the specimen labels do not have altitude data.
Biology. Unknown.
Comments. This monotypic genus is the sister group of Trilobitofoenus, with four shared synapomorphies. I decided not to group the Spinolafoenus + Trilobitofoenus clade into a unique genus because of the six synapomorphies exclusively shared by the Trilobitofoenus species. The autapomorphies of Spinolafoenus are the crenulate occipital margin, the truncate mesonotum, and the entirely light ovipositor sheath. These autapomorphies are not exclusive of Spinolafoenus. However, the genus has other exclusive characters in Gasteruptiinae that were not used in the cladistic analysis: mesosoma uniformly areolate; metacoxa areolate at posterior portion; and longitudinal axis of propodeum slightly concave. The Spinolafoenus isolation was probably the result of the Andes formation.
