Etymology

This species is dedicated to my great friend Kent Martin, who provided me with all the natural and cultural knowledge necessary to survive a year as a researcher in Australia. As Kent put it himself, the species furthermore has a certain adventurous air to it, which also is the case for its eponym.

Diagnosis

Forewing length 4.4–6.4 mm (holotype: 6.4). Antenna with 37–39 flagellomeres in both sexes (38). Head between eye and antennal base with protrusion ( Fig. 1 ). Ocelli of male not enlarged, distance of hind ocellus to compound eye about 1.5 times diameter of ocellus. Mesoscutum about as long as wide. Mesopleuron smooth and shining between strong punctures, with parallel wrinkles especially in anterior half and with large impunctate area around speculum. Area superomedia of propodeum wider than long, as long as wide, to up to 1.5 times longer than wide (wider than long); areas of propodeum smooth and shining between strong punctures. Portion of ovipositor that protrudes from metasoma 1.15–1.7 (1.7) times as long as hind tibia.

Description

Head Clypeus moderately large, wide, convex when viewed from side, margin convex; mandibles with lower tooth longer than upper tooth. Occipital carina complete, evenly arched or straight to slightly dipped above. Genal carina joining oral carina briefly before reaching base of mandible. Whole head coriaceous and matt, face and clypeus with dense and strong punctures, vertex with some sparse punctures. Antenna with last flagellomeres about as long as wide, scape excised at an angle of about 50°.

Mesosoma Pronotum with epomia often weak, sometimes distinct; mesoscutum with notauli barely reaching behind level of tegula; mesopleuron with sternaulus deeply impressed; scutellum not carinate. Propodeum with complete set of carinae, longitudinal carinae sometimes weak medially; metapleuron with short vertical carina arising above mid coxa. Mesosoma smooth and shining and with strong and dense punctures, mesoscutum but not scutellum coriaceous between punctures. Wings slightly tinged to hyaline, radial cell along anterior margin of wing 0.95–1.25 times as long as stigma, areolet large, almost rhombic; hind wing with vein Cu1 usually absent, distal abscissa of vein 1A short and weak. Legs simple, hind coxa coriaceous and matt.

Metasoma First tergite 1.6–1.85 times as long as second tergite, second tergite 1.45–1.9 times wider apically than basally. First tergite with rather shallow but long glymma, petiolus flattened; first sternite reaching to about half length of tergite, its sides parallel. Third tergite with laterotergite separated by crease at most at base; metasoma weakly compressed from tergite 3 onwards. Tergites smooth and shining, almost impunctate, tergites 1 and 2 sometimes with weak longitudinal striae. Ovipositor weakly to strongly downcurved, laterally compressed, with subapical notch; male clasper with oblique apical truncation.

Colouration of female

Head black, orange to yellow on most of clypeus, along inner and usually also outer eye margin, malar space, and lower part of gena, sometimes also main part of face yellow; antenna with median segments orange and basal segments brown. Mesosoma including scutellum and propodeum orange, mesoscutum black; legs orange, forewing with stigma often lighter in anterior half. Metasoma orange, posterior segments sometimes with some brown areas.

Colouration of male

As in female.
