- Archaeoteleia chambersi Early, John W., 2007, Zootaxa 1655: 8-11.
Archaeoteleia novaezealandiae (!), Chambers 1982: 44. Misidentification. Description: Female. Length 5.0– 5.6 mm. Color: shiny dark brown in fresh specimens, without greenishbrown areas; scutellum yellow-brown, usually paler than mesoscutum, rarely dark brown, concolorous with mesoscutum. Head (Figs. 3–5): frons lacking swelling by inner orbits, head not or only weakly browed in dorsal view; occipital carina entire but weaker and more crenulate medially than genal carina; A 1 3.9–4.9 times longer than wide; A 2 2.2–2.9 times longer than wide; A 3 3.8–4.2 times longer than A 2; flagellum with setae dense, appressed, flagellomeres without bristled appearance. Mesosoma (Figs. 3–4): transverse pronotal carina curved around anterior margin of mesoscutum, epomial corners distinct but not strongly raised, width between epomial corners 0.8 times width of mesoscutum; pronotal humeral carina well separated from mesoscutum, shoulders broad, at widest point about 0.8 times width of tegula; vertical epomial carina very weak or absent; lateral pronotum finely coriarious; netrion smooth or minutely aciculate; admedian lines subparallel to slightly divergent posteriorly, 1.4–1.6 times longer than separation of posterior ends; notaulus complete or incomplete, if complete would attain scutal margin at or between epomial corners; scutellum bilobate, scutellar spines distinct; dorsellum finely reticulate-coriarious; mesopleural carina incomplete, indistinct posteriorly; mesopleural depression with fine longitudinal rugulae; mesepisternum below carina with moderately dense setigerous punctures; upper half of metapleuron with small glabrous area anteriorly; medial excavation of propodeum with reticulate rugulose sculpture, medial carinae raised anteriorly to form a vertical toothlike structure bearing long erect setae; fore wing with distinct pigmented area under marginal vein between bulla and stigmal vein; postmarginal vein 3.5–4.3 times longer than marginal vein.
Metasoma (Figs. 1, 2, 4) 4.2–4.6 times longer than wide; T 1 slightly wider than long, T 2 –T 5 distinctly so, T 6 3.0– 3.5 times longer than wide; T 1 –T 5 with broad longitudinal furrow laterally (Fig. 2), sometimes weaker in posterior tergites; costae of T 1 strong but not more strongly impressed around base of horn; horn coriarious except for smooth and shining tip (Fig. 4); T 6 entirely coriarious-punctate, with some longitudinal carinulae; anterior lens-shaped area of S 2 often strongly angular and tooth-like in profile (Fig. 1). Male. Differs from female as follows: Length: 4.4–4.7 mm; A 1 3.5–3.9 times longer than wide; A 2 1.4– 2.3 times longer than wide; A 3 4.3–5.7 times longer than A 2; sex segments variable, either A 4 –A 6, A 4 +A 5 or only A 5 with small basal carinae, carina usually largest on A 5. Dorsellum strongly foveolate anteriorly, posterior half finely punctate; propodeum with dorsal surface entirely areolate-rugose, medial excavation weak. Metasoma 3.6–3.8 times longer than wide; T 1 with anterior margin raised medially, toothlike in profile; T 1 –T 5 without broad longitudinal dorsolateral furrows; anterior lens-shaped area of S 2 prominent and more or less angular in profile, but not as strong as in female. Diagnosis: Recognized by the following combination of characters: female body length 5.0– 5.6 mm, male 4.4–4.7 mm; clypeus with sharply angulate anterolateral corners; epomial corners not strongly angulate; transverse pronotal carina curved weakly around anterior margin of mesoscutum; scutellum bilobate, posterior corners with spine, usually paler than mesoscutum; fore wing with pigmentation under marginal vein; female metasoma 4.2–4.6 times longer than wide, T 6 3.0– 3.5 times longer than wide; male antenna with sex segments A 4–6 or A 4 + 5 or A 5 only. Distribution: Found widely in the North Island of New Zealand (ND, AK, CL, BP, TK, TO, WN) and sympatric with A. karere n.sp. at some localities. Link to Distribution Map. 210 /hymenoptera/eol_scelionidae.content _page?page_level= 3 &page_id=taxon_page_data&page_version= 190980 &page_option 1 =M Biology: Several specimens were reared from eggs of Rhaphidophoridae from old gold mining tunnels on the Coromandel Peninsula. The only weta in tunnels at Tokatea Track was Gymnoplectron uncata (Richards 1959) where it is presumed to be the host. Gymnoplectron fusca (Richards 1959) also inhabits tunnels in the Coromandel area and its eggs are probably parasitized as well. Etymology: The species is named in honor of Mr. F.D. Chambers who collected the first specimens and noted differences between them and A. novaezealandiae (Chambers 1982). Material Examined: Holotype female.

Early, podocarp-broadleaf forest, swept, male, AMNZ64322 (AMNZ). Remarks: Archaeoteleia chambersi is the most variable and widespread of the New Zealand species. Distribution of carinae on the sex segments of the male antennae has been used to separate species of scelionids. The presence of three forms with respect to this character (A 4 –A 6, A 4 +A 5, and A 5 only) might indicate that three species are present. The notauli vary from complete to incomplete. At the type locality (Mt. Taranaki) there is a correlation in the limited material available – both sexes have incomplete notauli and the male sex segments are A 4 –A 6. For other localities there is no correlation between these two characters. Most specimens examined have a scutellum that is distinctly paler than the mesoscutum, but in some (from the lower North Island) the scutellum and mesoscutum are uniformly dark brown. In the absence of any consistent differences in other characters, all specimens are included here in A. chambersi. It may prove to be a complex of two or more closely related species once more material is available for study.
