    A new species of Platygaster (Hymenoptera, Platygastroidea) from India with an unusual antenna

    Get PDF
    A new species, Platygaster harpagoceras Popovici & Veenakumari, is described from India. The most unusual features of this species are the acuminate shape of the last antennomere and the 9-merous antenna in both sexes. The male and female are described and illustrated with brightfield and scanning electron microscopy. We provide a comparative analysis of the acuminate distal antennomere in the superfamily Chalcidoidea, including several genera of Pteromalidae (Callitula Spinola, Homoporus Thomson, Norbanus Walker, Rhaphitelus Walker)

    The species of the genus Phanuromyia Dodd, 1914, belonging to the subfamily Telenominae are egg parasitoids of planthoppers belonging to the families Issidae, Flatidae, Fulgoridae and Ricaniidae (Hemiptera: Fulguroidea). So far eleven species of Phanuromyia are known from India. Fifteen new species of Phanuromyia Dodd are described here: P. chalukya sp. nov., P. chera sp. nov., P. chola sp. nov., P. ganga sp. nov., P. hoysala sp. nov., P. kadamba sp. nov., P. kakatiya sp. nov., P. kanva sp. nov., P. nirvighna sp. nov., P. pallava sp. nov., P. pandya sp. nov., P. rashtrakuta sp. nov., P. satavahana sp. nov., P. tuluva sp. nov. and P. vakataka sp. nov. A key to females of all the Indian species of Phanuromyia is provided

    Chakra Rajmohana and Veenakumari, gen. nov. (Figs 1–11) Type species: Chakra sarvatra Rajmohana and Veenakumari. Derivation of genus name. ‘ Chakra ’ in Sanskrit means wheel, referring to the unique wheel-like setigerous flat-topped tubercles distributed all over the head and mesosoma. The gender is feminine. Diagnosis. Although the specimens of the new genus key out to Opisthacantha Ashmead at couplets 59 of Masner (1976) and 50 of Austin and Galloway (1984), they do not fit into the concept of the genus Opisthacantha Ashmead sensu Masner (1976). The new genus differs from Opisthacantha in having frons, vertex, dorsal, lateral and ventral mesosomal surfaces with large, round, setigerous tubercles, whose diameter is almost equal to the diameter of the lateral ocelli (Figs 2, 11) and also in having remarkably small eyes that are hardly as long as temples, small ocellar triangle, with lateral ocelli much closer to median ocellus than to orbits (OOL> POL) and raised interantennal prominence. Description. Body minute, 1.0–– 1.2 mm long. Head and body brown to blackish brown; Frons, vertex, dorsal, lateral and ventral mesosoma with large round setigerous tubercles, the diameter of the tubercles almost equal to diameter of lateral ocelli. Head distinctly transverse dorsally, subellipsoidal, densely setose; Occipital carina present, crenulate, extending throughout and continuing on lower margin of postgena; Eyes small, shorter than temples; Interommatidial setae short, 1.7 times as long as the diameter of a single ommatidium, comparable both in size and density to setae on frons and vertex; Temple visible in dorsal view; Ocelli clustered in a small triangle on vertex; OOL>POL>LOL (Fig. 2); Frons convex without frontal depression; Interantennal process well developed with a pronounced curve (Fig. 3); Clypeus narrow, transverse, more than 3 × as long as wide; Mandibles short and wide (L: W = 39: 48), subtridentate, median tooth highly reduced relative to lateral teeth (Fig. 6); Teeth acute; Facial striae short, 0.9 × length of malar sulcus; Malar sulcus wide near inner orbit of eye; Subocular suture present (Fig. 3); Antenna with 12 antennomeres in both sexes, with 6 clavomeres in females (Fig. 8) and filiform in males (Fig. 7), male A 5 carinate. Mesosoma almost as long as wide in dorsal view, both mesosoma and mesoscutellum with similar sculpture as head; Skaphion and notaulus absent (Fig. 4); Mesoscutellum 2 × as wide as long, anterior margin crenulate; Lateral axillar area wide; Metascutellum foveolate with a broadly based triangular, medially pointed spine; Scutoscutellar sulcus wide; Epomial carina present; Netrion almost smooth, closed near fore coxa; Acetabular area setose, sculpture partially effaced in mesopleural depression; Mesepimeral sulcus foveolate; Metapleuron smooth dorsally, ventrally sculptured similar to mesonotum; Lateral propodeal area setose, with similar sculpture to that of head and mesoscutum; Propodeum with posterior margin concave medially, Posterior propodeal projection pointed downwards, with sparse setae (Fig. 4); Tibial spur formula 1: 2: 2. Fore wing extending beyond tip of metasoma in flexed position; Fore wing submarginal vein not reaching anterior margin and not curved posteriorly or broken before fore wing marginal vein; Fore wing marginal vein shorter than fore wing stigmal vein and fore wing postmarginal vein; Fore wing stigmal vein placed at a broad angle of 45 0 from fore wing margin (Fig. 9); other fore wing veins absent; Marginal ciliae present; Hind wing with submarginal vein complete. Metasoma pedunculate or spoon shaped (Fig. 1), widest at its apical two-third, nearly as wide as mesosoma, shorter than head and mesosoma combined; Metasomal tergites transverse, T 1 without horn; T 1 and T 2 costate, costae reaching posterior margin of tergite; T 3 longest and widest; 7 tergites and 8 mediosternites in both sexes; Laterotergites narrow; Submarginal ridge well impressed; T 6 visible as a thin strip with lower margin emarginated; T 7 represented by a short lobe, external and not exerted with ovipositor.Published as part of Keloth, Rajmohana & Kamalanathan, Veenakumari, 2014, Chakra, a new genus of Scelioninae (Hymenoptera: Platygastridae) from India, along with description of a new species, pp. 285-290 in Zootaxa 3821 (2) on page 286, DOI: 10.11646/zootaxa.3821.2.9, http://zenodo.org/record/22556

    Review of Odontoscelio Kieffer, 1905 (Platygastroidea, Scelionidae) with the description of two new species from India

    No full text
    All species of Odontoscelio Kieffer, 1905 are imaged, with keys provided to all known males and females in this genus. Two new species, O. agnieleae sp. nov. and O. spinosus sp. nov., are described from India. The generic concept of the genus Odontoscelio is discussed. The presence of axillular spines differentiates this genus from other teleasines such as Dvivarnus Rajmohana & Veenakumari, 2011, Gryonoides Dodd, 1920 and the Trimorus carus (Nixon, 1936) species group, which possess lateral mesoscutellar spines
