Schüepp, Christof & Olmi, Massimo, 2012, Catalogue of the Dryinidae and Sclerogibbidae (Hymenoptera: Chrysidoidea) of Belize, with description of two new species, Zootaxa 3346 (1), pp. 51-63 : 54-56

8. Anteon dykeae Olmi , sp. nov.

( Fig. 1 )

Etymology. This species is named after Miss Katie Dyke.

Types. Holotype, 3, BELIZE: Corozal District, Sarteneja , La Isla Road Cenote , Low semi-deciduous forest, 18°20.115'N 88°7.713'W, 2 m a.s.l., 11–17.xii.2009, Malaise trap 1, C. Schüepp coll. ( BER).

Diagnosis. Male with scutum mostly granulated; posterior surface of propodeum not sculptured by two longitudinal keels; distal apex of paramere broadly hollowed out ( Fig. 1 ).

Description. Male: fully winged; length 2.7 mm. Head black, except mandible testaceous; antenna brown, except segment 1 testaceous; mesosoma black; metasoma brown; legs testaceous, except clubs of profemora partly brown, mesotibiae partly brown, metacoxae, clubs of metafemora and metatibiae partly black. Antenna hairy, filiform, with segment 3 triangular; antennal segments in following proportions: 10:6:6:5:5:5:5:5:6:8. Head dull, granulated and reticulate rugose; frontal line complete; face with two lateral keels around orbits directed towards antennal toruli; vertex with two hardly visible oblique keels connecting posterior ocelli to occipital carina; occipital carina complete; POL = 9; OL = 5; OOL = 6; OPL = 5; TL = 4; greatest breadth of posterior ocelli about as long as TL. Scutum dull, granulated, except anterior margin rugose. Notauli incomplete, reaching about 0.25 length of scutum. Scutellum and metanotum shiny, smooth, punctate, without sculpture among punctures. Propodeum reticulate rugose, with strong transverse keel between dorsal and posterior surface; posterior surface without longitudinal keels. Fore wing hyaline, without dark transverse bands; distal part of stigmal vein shorter than proximal part (2:8). Paramere with distal apex broadly hollowed out, without distal inner pointed process ( Fig. 1 ). Tibial spurs 1/1/2. Female: unknown.

Distribution. Only known in the type locality.

Hosts. Unknown.

Comments. Because of the posterior surface of propodeum not sculptured by two longitudinal keels and the scutum mostly granulated, the male of A. dykeae is similar to those of A. albitarse ( Cameron 1888) , A. mayanum Olmi 1991 , A. desantisi Virla 1998 , A. ferale Olmi 1993 , and A. pilicorne Ogloblin 1938 . Following the description of A. dykeae , the key to the males of the Neotropical species of Anteon published by Olmi (1991) and modified by Olmi (1993c) and Virla (1998) may be modified by replacing couplet 22 as follows:

22 Distal apex of paramere broadly hollowed out ( Fig. 1 ).................................... A. dykeae Olmi , sp. nov.

- Distal apex of paramere not broadly hollowed out (Fig. 318 in Olmi 1984; figs 21 E, 25 C in Olmi 1991; fig. 17 in Olmi 1993c; fig. 4 in Virla 1998)................................................................................ 22'

22' Paramere much shorter than penis (Fig. 21 E in Olmi 1991)...................................... A. mayanum Olmi

- Paramere as long as, or slightly shorter than penis (Fig. 318 in Olmi 1984; fig. 25 C in Olmi 1991; fig. 17 in Olmi 1993c; fig. 4 in Virla 1998)..................................................................................... 22''

22'' Vertex of head with two oblique keels from posterior ocelli to occipital carina.................................. 22'''

- Vertex of head without two oblique keels from posterior ocelli to occipital carina............................... 22''''

22''' Distal region of paramere with many papillae (Fig. 4 in Virla 1998)................................ A. desantisi Virla - Distal region of paramere without papillae (Fig. 17 in Olmi 1993c)................................... A. ferale Olmi

22'''' Paramere with apical margin of distal inner process not serrate (Fig. 318 in Olmi 1984)............ A. pilicorne Ogloblin

- Paramere with apical margin of distal inner process serrate (Fig. 25 C in Olmi 1991)............. A. albitarse ( Cameron)
