03BA3B47FFE83942FE2FD5440CAE7A63.taxon	description	T y p e s p e c i e s: Imeria albomaculata CAMERON, 1903. D i a g n o s i s: Body medium-sized, length 6 - 12 mm. Flagellum long and slender, bristle-shaped or slightly lanceolate. Head extremely thick, nearly cubital in dorsal view (figs 17 - 28). Occiput between ocelli and occipital carina not or slightly slanting and very wide (figs 17 - 28). Apical margin of clypeus thin, with median angle, laterally often ± curved upward (figs 5 - 16). Malar space slightly shorter than width of mandibular base (fig. 1). Mandible strongly twisted, its apex turned about 20 ° to 70 ° from its base and the dorsal surface turned up into plane of clypeus, with two large teeth of almost equal size and rather wide gap between teeth (figs 1 - 2). Genal carina reaching mandibular base. Epomia usually long. Collar simple, without lamella. Epicnemial carina sometimes ± elevated behind fore coxa. Mesoscutum about as long as wide. Scutellum strongly raised above postscutellum, with complete and sometimes lamelliform or dentiform lateral carina (fig. 3). Juxtacoxal carina largely absent but often indicated at frontal margin of metapleuron. Posterior transverse carina of mesosternum interrupted before mid coxa. Propodeum with nearly complete carination and narrow basal furrow behind postscutellum, fairly short (figs 39 - 42); area petiolaris much longer than basal horizontal part of propodeum medially. Area basalis present and carinated (figs 41 - 42) or replaced by a median longitudinal ridge (figs 39 - 40). Area superomedia slightly longer than wide or wider than long. Area dentipara usually sloping downward in a gentle curve, its posterolateral edge sometimes with short denticular apophysis. Hind coxa usually without, sometimes with weak scopa. Claws simple. Areolet pentagonal; vein 1 cu-a interstitial or slightly postfurcal. Metasoma oxypygous (figs 1, 43), at least 2 nd to 4 th sternites with median folds. Petiole about as wide as basally high. Postpetiole moderately widened, without separated median field, usually with fine sculpture, not aciculate. 2 nd tergite with wide impressed gastrocoelus and thyridium. Thyridium very large and much wider than interval between thyridia (figs 44 - 51). 2 nd tergite usually slightly wider than long (figs 44 - 50), rarely longer than wide (fig. 52). Apical tergites often weakly sclerotized and ± depressed or compressed (at least in prepared specimens, figs 46, 48). Ovipositor sheath slender and stick-shaped, about 2 × as long as apical depth of metasoma (fig. 4). Color: Body usually black, rarely ± red, with extended ivory coloration. Flagellum at least in ♀ with ivory ring. R e m a r k: The taxonomical treatment of Imeria CAMERON, Caenojoppa CAMERON and Elasmognathias ASHMEAD was a matter of discussion in the past due to different and changing opinions of the authors. Caenojoppa CAMERON and Elasmognathias ASHMEAD were synonymized by HEINRICH (1934), but he separated Imeria CAMERON as a different genus due to the structure of the area basalis (replaced by a median longitudinal ridge in Imeria but distinctly present as a carinated field in the other groups). TOWNES et al. (1961) have treated all three taxa as subgenera of Imeria. In a newer analysis, HEINRICH (1967) considered to treat all three taxa as different genera since he could not find any intergrades in his African and Oriental material. In this study, Imeria is treated as a (rather homogenous) genus which can be easily identified and separated from other genera of Ichneumoninae by the specialized and unique structure of the mandible. Imeria sensu stricto differs clearly and constantly from Caenojoppa by several features such as the median carina of basal propodeum and slightly lanceolate flagellum in ♀ (see key below), and both taxa are treated as different subgenera here. In the Oriental material at hand, some of the members of Caenojoppa and Elasmognathias show a mix of the features that were formerly used for a separation such as the presence of apophysis, length of notaulus and form of epicnemial carina; the morphological features are also ± variable in both sexes. As already proposed by HEINRICH (1934), I therefore treat Caenojoppa and Elasmognathias as synonyms here.	en	Riedel, Matthias, C, Imeria (2025): The genus Imeria CAMERON in the Oriental region (Hymenoptera, Ichneumonidae, Ichneumoninae).

The propodeum and hind coxa are usually mainly red instead of black, but some specimens from the long series in SDEI have a completely black and ivory mesosoma. I was not able to find any other color or structural differences between the Indian and Taiwanese material. In my opinion, Imeria formosana (UCHIDA) represents a subspecies of I. albomaculata. It should be noted here that the examined Imeria specimens from Vietnam, Laos and the Hainan Island of China belong to different but closely related species.

R e m a r k: In his original description of Elasmognathias albitarsis, CUSHMAN (1922) mentioned only minor differences to I. cephalotes (ASHMEAD) such as a distinctly elevated scutellum and slightly different color pattern of the hind tarsus. As already stated by HEINRICH (1934) in a longer series of I. cephalotes, the form of scutellum is variable and probably correlates with the size of the specimens. In my material, the color of hind tarsus is also variable. In recognition of this variability, both species are synonymized here.

In 1933, HEINRICH (1937: 261) studied this type in London but mentioned it as a female. This interpretation was adopted, published and the specimen designated as lectotype by TOWNES et al. (1961). It is not clear if TOWNES really studied the type because there is none of his labels at the original material. Also, CAMERON did not mention other than the type material. In my opinion, the statement of HEINRICH (1937) could be a lapsus, and the “ lectotype ” in the NHM is in fact the male holotype of this species.
