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.

1(2)	Metanotum without spine. Mandible with convexity between teeth 1 and 2 ( ”Interkalarwölbung” Fischer 1993: 484; Fig. 25, see arrow). First flagellomere 2.5 times as long as second flagellomere (Fig. 26). Fore wing: r issuing distally from pterostigma, n. rec. antefurcal (Fig. 27, see arrow). Paraclypeal pit long, its length greater than distance between pit and compound eye (Fig. 28). Two species in the Ethiopian Region	Kritscherysia Fischer, 1993
2(1)	Metanotum with spine (Fig. 24). Mandible with a fourth tooth between teeth 1 and 2 (Fig. 20, see arrow). Flagellomeres 1 and 2 equal in length (Fig. 34). Fore wing: r issuing from middle of pterostigma (Fig. 21), n. rec. interstitial (Fig. 40, see vertical arrow). Paraclypeal pit short, its length as long as distance between pit and compound eye (Fig. 35). One species in the Neotropical Region	Telmogarbus gen. n.

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.

1(2)	Mandible strong and broad, 1.2-1.4 times as long as broad between upper and lower teeth ( Fig. 29 ). First tergite as long as to 1.2 times as long as broad posteriorly, strongly widening posteriorly ( Fig. 30 ). Flagellomeres thick, first flagellomere 2 to 3 times as long as broad, second flagellomere variably longer / as long as / shorter than first flagellomere ( Fig. 31 ). Fore wing: 3-SR at most as long as 2-SR or shorter, i.e. second submarginal cell short ( Fig. 32 ). Wings dark, infumate. - Twelve described species in the Neotropical Region ( Yu et al. 2005)	Gnathopleura Fischer, 1975
2(1)	Mandible usual in size, 1.8 times as long as broad between upper and lower teeth ( Fig. 20 ). First tergite 1.8 times as long as broad posteriorly, subparallel-sided ( Fig. 33 ). Flagellum thin, first flagellomere 10 times as long as broad, second flagellomere as long as first flagellomere ( Fig. 34 ). Fore wing: 3-SR 1.5 times as long as 2-SR, i.e. second submarginal cell long ( Fig. 21 ). Wings hyaline. - One species in the Neotropical Region	Telmogarbus gen. n.

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.

1(2)	Mandible with three teeth ( Fig. 17 ). Fore wing: 3-SR shorter than (or at most as long as) 2-SR, i.e. second submarginal cell short; pterostigma with r issuing distal to its middle ( Fig. 18 ; Fig. 83 in Wharton 1997: 109). Notauli not turning into crenulate lateral margin of mesoscutum ( Fig. 19 , see arrow). Axilla without excrescense; metanotum without spine. Fourteen species in Old and New World	Cratospila Foerster, 1862
2(1)	Mandible with four teeth, fourth tooth between first and second teeth ( Fig. 20 , see arrow). Fore wing: 3-SR 1.5 times as long as 2-SR, i.e. second sub marginal cell long; pterostigma with r issuing from its middle ( Fig. 21 ). Notauli turning into crenulate lateral margin of mesoscutum ( Fig. 22 , see arrow). Axilla with lamelliform excrescense ( Fig. 23 ); metanotum with spine ( Fig. 24 ). One species in the Neotropical region	Telmogarbus gen. n.

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.
