Yoshimotoana Huber, gen. n.

Yoshimotoana Huber, gen. n. (= masneri species group, of authors) (Figs 289–317) Type species. Yoshimotoana masneri (Yoshimoto), by present designation. Diagnosis. Within Gonatocerini, the single species of Yoshimotoana is distinguished by the following combination of features: pronotum entire, as long as mesonotum (Figs 293, 303, 304, 307); propodeum deeply pitted over most of its surface; petiole about twice as long as metacoxa, almost as long as gaster (Figs 309–313); gt1 the longest tergum, its posterior margin distinctly notched medially (Figs 309, 310). Description. FEMALE. Large specimens, 1765–2100 Μm in length. Colour. Body yellow except trabeculae, flagellum and metatibia brown (Fig. 289). Head. Head (Figs 290, 297–301) about 1.8× as wide as long and about 1.5× as wide as high; in lateral view with anterior surface flat above torulus, to slightly convex and sloping to mouth opening below torulus. Face about 1.2× as wide as high; subantennal sulci strongly converging, the distancebetween them at mouth margin less than half distance to preorbital sulcus; preorbital sulci curving slightly outward to below ventral margin of eye then curving sharply inward towards clypeus just above anterior margin of mouth. Toruli slightly more than their width from transverse trabecula. Eye in lateral view as high as long, its dorsal part well separated from back of head. Malar space about 0.5× eye height; malar sulcus absent. Gena in lateral view at level of dorsal part of eye quite wide, about half as wide as area at level of ventral part of eye. Vertex in lateral view horizontal, at right angle to face, posteriorly almost at right angle with occiput, with a fine line behind lateral ocelli separating vertex from occiput. Ocelli with LOL 0.5× POL or a little less and OOL about 0.8× POL, with two setae between lateral ocelli. Occiput entire. Labrum with 5 setae. Mandible with 3 normal teeth (Fig. 302). Antenna. Scape about 4.2× as long as wide, (Fig. 291) with radicle distinct, about 0.3× scape length; pedicel 0.3× scape length and at most about 0.5× as long as and slightly wider than fl1; funicle 8-segmented, fl1–fl8 at most with 2 mps; clava with 8 mps (Fig. 291). Mesosoma. About 2.0× as long as wide, 2.0–2.1× as long as high, and 1.1× as wide as high (Figs 293, 303, 304). Pronotum in dorsal view long and entire (Figs 303, 307), with dorsal surface separated from lateral surface by a rounded edge, and lateral surface concave in posterior 0.4 (from posterior part of propleura to below spiracle). Pronotal spiracle larger than propodeal spiracle (Fig. 204). Propleura abutting along most of their median length (Figs 305, 306). Prosternum rhomboidal, divided by longitudinal sulcus extending almost its entire length (Figs 305, 306). Mesonotum in dorsal view with narrow, fairly deep notauli (Fig. 303). Transscutal articulation straight. Scutellum slightly wider than long. Axilla normal. Prepectus wide and rectangular (Fig. 304). Mesopleuron spindle-shaped and truncate at both ends, without visible sulcus separating mesepisternum from mesepimeron. Metanotum with dorsellum somewhat triangular, its posterior margin rounded. Metapleuron large and oval, separated from propodeum by strongly curved line of abutting pits. Propodeum in lateral view slightly convex and weakly sloping, dorsally almost in same plane as dorsellum, in dorsal view with two straight, parallel submedian carinae and smooth between carinae except for row of deep pits laterally along each carina, the remainder of propodeum almost entirely covered with longitudinal rows of deep pits (Figs 304, 308). Propodeal spiracle small, separated by about its diameter from metanotum. Wings. Fore wing (Fig. 292) about 3.8× as long as wide, with microtrichia fairly dense and uniform distally, absent proximally behind and just beyond venation except for a few microtrichia behind stigmal vein and apex of parastigma. Venation 0.4× wing length. Submarginal vein with a dorsal macrochaeta and a short and inconspicuous ventral hypochaeta basally, and the apical hypochaetae absent. Remaining venation (parastigma + stigmal vein) with hypochaeta closer to distal than proximal macrochaeta and with 4 or 5 setae between the macrochaeta. Stigmal vein with apex oblique. Hind wing normal (Fig. 292). Venation about 0.50× wing length. Metasoma. Petiole much longer than wide, almost as long as gaster (Figs 311–313). Gaster 1.6–2.0× as long as high, gt1–gt5 with posterior margins crenulate.Terga with white membrane at most narrowly visible between them (Fig. 289). Ovipositor sheaths not exserted beyond gaster apex, with 1 subapical seta. MALE. Colour. As in female. Antenna. Scape short, with radicle not distinguishable (Fig. 295); pedicel about 0.41× scape length; flagellomeres each with about 12 mps (fewer on apical flagellomeres). Metasoma. Gaster somewhat cylindrical (Fig. 296). Genitalia with aedeagal apodemes narrowly V-shaped, not extending anteriorly as far as apex of apodeme of genital sternum. Discussion. Yoshimoto (1990) described the features of his masneri species group based on one included species. Zeya and Hayat (1995) distinguished this species group from other species groups in a key. Triapitsyn et al. (2010) described a second species and treated both as the masneri subgroup of species, placing it within the ater group of Gonatocerus (Cosmocomoidea). Their species is synonymized below on the basis of the funicle segment colour being slightly variable, from uniformly dark brown to lighter brown with fl6 and sometimes fl5 and fl7 whitish. A slide mounted female antenna from a topotypical specimen from El Rio (La Vega), for some reason not listed by Yoshimoto (1990) as a paratype, has one funicle segment whitish whereas the holotype has the entire funicle dark brown. Etymology. Yoshimoto + “-ana”, a Latin adjectival suffix that means belonging or pertaining to. The generic name is feminine. The genus is named after Carl Yoshimoto, my predecessor in the Canadian Forest Service, who recognized how distinct the species was and placed it in a new species group of Gonatocerus, the masneri group (Yoshimoto 1990). Distribution. The single species in Yoshimotoana occurs in the Dominican Republic. Hosts and habitat. Hosts are unknown. The habitat is various types of forest from dry montane to wet coastal. Included species: Yoshimotoana masneri (Yoshimoto), comb. n. from Gonatocerus. Gonatocerus masneri Yoshimoto, 1990: 88; holotype ♀ in CNC (examined). TL: Dominican Republic: La Vega, El Rio.
