description: Dilyta subclavata Förster
Dilyta subclavata Förster, 1869: 338.
Charips microcera Haliday in Marshall, 1870: 181. Synonymyzed by Quinlan & Evenhuis (1980: 429).
Glyptoxysta heterocera Thomson, 1877: 814. Synonymyzed by Hellén (1958: 64); Menke & Evenhuis (1991:152) mentioned that this synonymy was made by Hellén (1963), but it was actually Hellén (1958).
Glyptoxysta talitzkii Belizin 1966: 7. Apocharips talitzkii after Menke & Evenhuis (1991: 149). NEW SYNONYMY.
Type material studied. D. subclavata: NHMW: one pin with 2Ƥ: “Först.”, “Collect. G Mayr”, “Dil. subclavata Förster, Type ”, “ Dilyta subclavata Frst. ”, “ Dilyta subclavata Förster 2ƤƤ det. H.H.Evenhuis 1976” (orange), “das rechte Weibchen ware alb Lektotypus zu wählen H.H.Evenhuis” (orange). Comments: the original type material of D. subclavata consisted in two pins with two specimens each. However, the two specimens on one of the pins do not belong to D. subclavata but to Alloxysta sp. Thus, we have removed this pin from the type series. Glyptoxysta heterocera: EMLU: 1Ƥ: “Weld 1931” (Red label) “ heterocera ” “1969 100” “1984 329” “ Lectotype ” “ Lectotype Glyptoxysta heterocera det. N.D.M.Fergusson, 1984” “ ZML 2006 219”; 1 Ƥ: “Rsiö” “1969 101” “1984 330” “Para- Lecto- Type ” (Blue label) “ Paralectotype of Glyptoxysta heterocera det. N.D.M.Fergusson, 1984” “ ZML. 2006 220”. Glyptoxysta talitzkii: ZIN: 13: “Kishinev MSSR, 8.VI.57. Talickij” (in Russian), “ Ps. pyri N1052”, “ Holotypus 3 Dilyta talitzkii m V.Belizin det” (red).
Diagnosis. Similar to D. japonica n. sp., D. longinqua n. sp. and D. sinica n. sp. in having distal area of metasoma punctate. Differs from these in proportions of antennal segments (see key). Differs from D. aleevae n. sp. and D. rathmanae these having distal area of metasoma smooth without punctures.
Redescription. Length: 1.2–1.5 mm.
Colour: Head, mesosoma and metasoma dark brown. Antennae and legs yellow.
Antennae (figs. 3B, 4B): Female. F1 slightly shorter or subequal than pedicel, F2 subequal to F3, F4 slightly shorter than F1 but longer than F2 and F3, F1 subequal to F5, F6 longer than F5; F6–F11 wider than previous segments, antenna slightly clavate from F6; sensilla beginning on F6–F7. Male. F1 slightly longer than pedicel, sometimes slightly arched, F2 shorter than F1 and F3, F3 shorter than F1, F1 subequal to F4; F4–F12 wider than previous segments, antenna slightly clavate from F4; sensilla beginning on F4.
Metasoma: Distal half with a punctate area.
Biology. Hyperparasitoid of psyllids through Encyrtidae (Chalcidoidea). Reared from Psylla pyri (L.) and Psyllopsis fraxini (L.) (Menke & Evenhuis 1991). According to label data, the specimens from Netherlands were collected on Fraxinus excelsior L. (Oleaceae) but lacking host data.
Distribution. Europe. Cited for the first time in this study from Norway, Sweden, Netherlands and USA (Alaska).
