Name

Telmogarbus Papp, 2012 gen. n. – Wikispecies link – ZooBank link – Pensoft Profile

Type species:

Telmogarbus olivai gen. et sp. n. (monobasic and present designation).

Etymology

The new genus receives the fantasy name, Telmogarbus.

Description

Body gracile. Antenna filiform, flagellomeres very long. Head in dorsal view transverse, eye distinctly longer than temple (Fig. 36). Mandible with four teeth, fourth tooth between first and second teeth (Fig. 20, see arrow). Maxillary palp very long, about twice as long as height of head. Face and clypeus much wider than high. Paraclypeal pit short, i.e. not reaching compound eye (Fig. 35). Ocelli medium-sized, elliptic. Pronope small, distinct. Notauli evenly deep, meeting behind, finely crenulate; mesoscutal dimple missing. Prescutellar furrow wide, with a few crenulae. Axille with pair of lamelliform excrescences (Fig. 23). Metanotum medially with thin, long spine curving posteriorly (Fig. 24).Propodeum polished, carinate (Fig. 38). Precoxal suture distinct, crenulate. Epicnemial carina present. Legs long and thin. Fore wing as long as body. Pterostigma widening medially, second submarginal cell long: 3–SR clearly longer than 2–SR, m–cu interstitial (Fig. 21). First tergite petiolate, beyond first tergite metasoma narrow, tergites polished, tergites 2–3 fused (Fig. 33). Hypopygium small, ovipositor sheath short. Ground colour of body yellow to (light) brown. Wings hyaline.

Diagnosis

The new genus is near to the Palaearctic genus Kritscherysia Fischer (Fischer 1993: 484), to the Neotropic Gnathopleura Fischer (Fischer 1975: 128) and to the Palaearctic / Oriental / Nearctic genus Cratospila Foerster. The generic differentation of the four genera is presented below.
1.) Distinction between Kritscherysia and Telmogarbus: Common features of the two genera are the pair of more or less lamelliform excrescenses laterally from the prescutellar furrow (or on axillae) (Fig. 23; Abb. 54 in Fischer 1993: 485), long second submarginal cell (Fig. 21; Abb. 51 l.c.), long flagellomeres (Figs 26, 34) and ground colour of body yellow to light brown. The two genera are distinguished as follows.

2.) Distinction between Gnathopleura and Telmogarbus: The new genus runs to Gnathopleura Fischer in Wharton’s (1997: 88–98) identification key to the alysiine genera of the Neotropical Region, their common feature is the fourth tooth between teeth 1 and 2 (Figs 20, 29, see arrows); the distinction between them is presented here.

3.) Distinction between Cratospila and Telmogarbus: disregarding the number of mandibular teeth, the new genus will run to Cratospila Foerster (Wharton 1997: 88–98) by virtue of their delicate body shape, very long flagellomeres and long first tergite; the two genera differ from each other by the features in the key below.

Taxonomic remark. The three genera related to the new genus Telmogarbus are known to me by the following material: 1.) Cratospila by females and males of Cratospila circe Haliday; 2.) Gnathopleura by a few Neotopical species; 3.) Kritscherysia by two male paratypes of Kritscherysia longimembrum Fischerand the original description.
