Differential diagnosis
Kibalus nonnaritae Dal Pos & Di Giovanni sp. nov. can easily be distinguished from the other species of the genus by two peculiar characters: the very elongated labial palpus, which reaches and surpasses the fore coxae, and the absence of a postpectal carina ventrally, which is unusual for Kibalus (Fig. 26C). Using Rousse et al. ’s (2013) key, it keys out to Kibalus mubfs Rousse & van Noort, 2013, but it is differentiated from it by the following characters: (1) face completely white, with frons, ocellar triangle, and vertex black (Figs 26B, 27A); (2) mesoscutum with two black lateral longitudinal carina (Fig. 26B); (3) propodeum mostly brownish-black (Fig. 26B); (4) mesopleuron and metapleuron completely smooth (Fig. 26C); (5) frons, ocellar triangle, and vertex smooth and shining (Fig. 26B); (6) 1 st flagellomeres 2× as long as the 2 nd (Fig. 26A, 27A); (7) antenna with white annulus (Fig. 26A).
Etymology
The species is dedicated to the first author’s grandmother, Rita Zanin, and the specific epithet is the combination of two terms: ‘ nonna ’ (Italian word for ‘grandmother’) and ‘ ritae ’ (female noun in the genitive case formed from a modern person name (ICZN 1999: article 31.1.2)). For her constant and indefatigable support to her family over the entire span of her life and for the tacit understanding of DDP during the many summers he spent in grandma’s backyard, looking for small creatures. Without that initial support, this new species could not have been described.

MEASUREMENTS. Body length: 7.7 mm; fore wing length: 5.6 mm.
HEAD (Figs 26B, 27A). Overall shining; face subquadrate, as wide as medially high, smooth and almost impunctate, medio-apically protruding in a very distinct blunt tubercule right below the antennal sockets, clear delimitation between clypeus and face absent; frons and vertex almost completely smooth, impunctate; ocellar triangle equilateral and not elevated; ocular-ocellar distance about 1.3 × ocellus diameter, inter-ocellar distance 1× ocellus diameter; occipital carina distinct and complete, meeting hypostomal carina at base of mandible; temples slightly inflated in dorsal view; gena, in lateral view, medially strongly inflated, smooth; clypeus smooth, shining with straight apical margin; malar space short, about 0.5× basal width of mandible; mandible robust, with sparse setiferous punctures in the central area, teeth rather stout and widely separated with the ventral tooth shorter (about 0.8×) than the upper tooth; maxillary palpi long, reaching fore coxae, 5 th segment about 1.5 × as long as 4 th; antenna filiform, not tapering, flagellum with 28 flagellomeres, the 1 st flagellomere about 1.4× as long as the 2 nd, preapical flagellomeres distinctly longer than wide.
MESOSOMA (Fig. 26A–C). Overall shining; pronotum smooth, shining and impunctate; epomia absent; propleuron smooth, shining and almost impunctate, projected into a blunt, rounded flange ventro-apically; mesoscutum subquadrate, smooth, finely and sparsely punctate, notauli short and distinct only anteriorly; scutellum slightly elevated over metascutellum, almost impunctate, carinated throughout; mesopleuron shining all over, smooth on the upper ⅔ and sparsely and finely punctate ventrally, speculum smooth, epicnemial carina laterally ending at anterior edge of mesopleuron; sternaulus distinct on ⅔ of the length; posterior transverse carina of mesosternum incomplete, absent in front of mid coxae and slighty raised between mid coxae; metapleuron smooth, shining and impunctate, juxtacoxal carina strong; propodeum short in lateral view, sloping gently with almost no horizontal part; anterior transverse carina present with area basalis and area superomedia separated and shagreen, area externa and area dentipara separated and shagreen; area spiracularis and area lateralis shagreen and shining.
LEGS (Fig. 26A). All coxae smooth, hairy and impunctate; hind coxa without scopa. Hind femur about 3.3–3.6× as long as medially high. Tarsal claws without pecten.
WINGS (Fig. 26A). Fore wing with 3rs-m present, areolet pentagonal and large; 1cu-a opposite M&RS, CU between 1m-cu&M and 2cu-a about 0.7× as long as 2cu-a. Hind wing with distal abscissa of CU present, pigmented, CU about 3 × as long as cu-a.
METASOMA (Fig. 27B). First tergite shagreen throughout; 2 nd tergite superficially and densely punctate, gastrocoeli indistinct; thyridia transverse, space between them smaller than one of them; 3 rd tergite superficially and densely punctate; the rest of the tergites shagreen; dorsal basal part of gonoforceps smooth and shining, hairy shagreen apically.
COLORATION (Figs 26–27). Head with face, clypeus, mandibles (except the black apical teeth), orbits all around the eyes (except for a spot on vertex), and genae pale yellow; black are: mandibular teeth, ocellar triangle, frons, vertex, and temples.Antenna with scape and pedicel reddish-brown; flagellum black with white annulus present only on the dorsal side, from the 9 th to 13 th /14 th flagellomeres. Mesosoma yellow, with base and lateral lobes of mesoscutum, metanotal trough, and propodeum (except area petiolaris) infuscated; tegulae pale yellow; the overall ventral side is pale yellow while the dorsal sclerites are mostly orange. Legs overall yellowish-brown, with fore and mid coxae, fore and mid trochanter, and basal portion of fore and mid tibia pale yellow; hind coxae bicolored, pale yellow in the basal half and reddish brown in the apical half; hind leg overall more infuscated than the fore and mid legs. Wing entirely hyaline. Metasoma entirely brownish-black, except for the white basal portion of the 1 st tergite, the white apical bands on 2 nd and 3 rd tergites, the white gastrocoeli and thyridia, and the white central spot on the 7 th tergite; gonoforceps brownish-black with a white apex, penis valvae also pale yellow.
