Archaeoteleia onamata Early , new species

Figures 20–23

Description: Female. Length 5.6–6.4 mm. Color: central upper frons, vertex and occiput pale golden brown to dark brown, sometimes almost black, particularly ocellar triangle; frons along inner orbits, genae, clypeus and mandibles pale; mesonotum medium golden brown to dark brown; pronotum, lateral mesosoma, coxae, trochanters and femora pale greenish to yellow; ovipositor horn of T1 always dark brown to almost black, always the darkest part of the body; tergites dark brown medially, orange brown laterally; sternites paler, yellowish brown.

Head ( Figs. 21–23 ): vertex, temples and upper frons very finely coriaceous-punctate, setae short and very fine; occipital carina complete, finely crenulate medially but with only a few fine punctures in genal region; cheeks with dense, fine setigerous punctures, striation weak but strongest basally near mandibular articulation; striation of lower face most pronounced in malar region and on clypeus; central carina of frons very weak, fine, sometimes incomplete; frons with smooth shallow depression on side for reception of scape, without swelling by inner orbits, head not browed in dorsal view; A1 4.0–4.3 times longer than wide; A2 2.4–3.4 times longer than wide; A3 4.2–5.0 times longer than A2; flagellum not conspicuously bristly, with few erect setae, setae mostly appressed and short, less than half width of A3; claval formula A5–12/1-2-2-2-2-2-2-1.

Mesosoma ( Figs. 22–23 ): dorsal pronotum with transverse pronotal carina bowed in front of anterior margin of mesoscutum, epomial corners distinct but not raised or sharp; pronotal shoulders broad, at maximum width 0.75 times as wide as tegulae; vertical epomial carina absent; lateral pronotum with small narrow glabrous area medially; netrion punctulate, with short, fine, semi-appressed setae posteriorly directed; mesoscutum with dense, fine setulose punctures; admedian lines always clearly defined, long, 3.0–4.4 times longer than separation of posterior ends; notaulus complete, finely crenulate, strongest posteriorly, becoming weaker and less distinct anteriorly, subparallel and diverging only slightly anteriorly, ending before epomial corners; parapsidal line clearly indicated; scutellum virtually not bilobate, without spines; mesopleural carina absent; anterior margin and mesepisternum below depression with dense setigerous punctulae, setae very fine, whitish, appressed and obliquely posteroventrally directed; mesopleural depression and area above entirely smooth and almost glabrous; upper half of metapleuron largely smooth and glabrous, lower half not distinctly swollen, densely finely punctulate and hairy like lower mesopleuron; medial excavation of propodeum smooth, flanked by carinae raised anteriorly to sharp tooth-like spine bearing long erect setae; fore wing hyaline, without infuscation under marginal vein between bulla and stigmal vein; stigmal vein distinctly curved basad; postmarginal vein long, 4.0–5.0 times longer than marginal vein, becoming indistinct gradually.

Metasoma ( Fig. 20, 23 ) 5.0–5.5 times longer than wide; T1 and T5 about as long as wide, T2–4 only slightly wider than long, T6 3.7–4.1 times longer than wide; sculpture very fine; T1 with longitudinal costulae sometimes not well impressed around base of ovipositor horn and interrupted by coriaceous wrinkling, horn finely coriaceous, smooth and shining only on tip; T2–5 with vague shallow longitudinal depression laterally, anterior margins costulate, costulae sometimes complete medially on T2 and T3 but usually only present laterally with broad finely coriaceous medial region.

Male. Differs from female as follows: Length 4.8–5.0 mm; upper frons, vertex, occiput, dorsal mesosoma and metasoma dark brown, always darker than female; A1 2.9–3.0 times longer than wide; A2 1.4–1.7 times longer than wide; A3 5.7–6.0 times longer than A2; only A5 distinctly carinate but A4 often with small vestige of a basal carina.

Propodeum with indistinct weak medial depression flanked anteriorly by delicate propodeal carinae which are not distinctly raised or tooth-like.

Metasoma 4.1–4.2 times longer than wide; T1 longer than wide, anterior margin raised.

Diagnosis: Recognized by the following combination of characters: large body size, female body length 5.6–6.4 mm, male 4.8–5.0 mm; notaulus complete; scutellum barely bilobate and without spines at posterior corners; fore wing without pigment cloud under marginal vein; mesepisternum below mesopleural depression covered with dense, fine pilosity, male antenna with A5 carinate, A4 sometimes with small carina.

Distribution: Found primarily in parts of the north of the South Island of New Zealand (SD, NN, BR, NC). It is sympatric with A. novaezealandiae and A. gilbertae in one locality (NN, Roding Valley), and also at the type locality with A. gilbertae .

Biology: Hosts unknown but presumed to be eggs of a large macropathine rhaphidophorid.

Etymology: The word onamata in the Māori language means 'from ancient times' and reflects our belief that this is the most plesiomorphous species of the genus.
