Colour . Antenna brown; head yellow, except stemmaticum and occiput dark brown; pronotum mesonotum yellow; mesopleuron ventrally and propodeum brown; fore and middle legs yellow, except telotarsus yellowish brown; hind coxa brown; hind femur and hind tibia apically brown, except hind femur apically and basally, hind tibia basally yellow; hind trochanters and trochantellus, hind tarsus yellow, except telotarsus brown; wing veins yellowish brown; metasomal tergites 1–3 yellow, except 2nd–3rd tergites medially dark brown; 4th–6th tergites pale yellow dorsally; postero-lateral lobes of 3rd–5th tergites, 4th metasomal sutures yellowish brown; ovipositor sheath brown; ovipositor yellow. Male. Unknown. Distribution . NW Vietnam ( Hoa Binh ). Biology . Unknown. Etymology . From “imitor” Latin meaning “copy, mimic”, because the new species is similar to Testudobracon descensus , sp. nov. by having ovipositor abruptly bent downward subapically. Notes . Testudobracon imitator sp. nov. is close to T . athashi Ranjith , from India but differs from the latter by following characters: 1) Ovipositor 0.9 × metasoma (0.6 × in T . athashi ); 2) Vein 3-SR of fore wing distinctly longer vein (1.4 ×) vein 2-SR (in T . athashi vein 3-SR subequal to vein 2-SR; and 3) Propodeum, hind coxa and lateral lobes of third–fifth metasomal tergites blackish brown (propodeum, hind coxa yellow in T . athashi ); T . imitator , sp. nov. is also close to T. tatyanae Quicke & Ingram , from Australia , but differs from the latter by the following characters: 1) Second-third metasomal tergites with acute postero-lateral lobes (rounded postero-lateral lobes in T. tatyanae ); 2) Notauli deep and wide posteriorly, sparsely cranulate; and 3) Third metasomal tergite 2.8 × wider than long (2.25 × in T. tatyanae ).
