Callipharixenos philippines Kathirithamby & McMahon new species

Type. Holotype. female: Philippines , Carabao, Pico & Katchamitha, sweep net, 1994-98 (V. R. Ocampo, G. M. Anober, R. S. Rejesus)

Paratype female: Philippines , Carabao, Pico & Katchamitha, sweep net, 1994-98 (V. R. Ocampo, G. M. Anober, R. S. Rejesus)

Female cephalothorax ( Fig. 9 ). Long and narrow and twice as long as wide (length = 0.42mm, width = 0.22mm). Metathorax and 1st abdominal segment raised above the host and very dark, narrowing anteriorly. Rostrum positioned anteriorly with mandibles on either side, below which is the mouth opening. Brood canal opening rounded (length = 0.07mm, width = 0.10mm) and about a third from the top of the cephalothorax.

Host. Idioscopus clypealis (Lethierry) ( Hemiptera : Cicadellidae ).

Biological Notes. No males were found in the present samples and the females had developing embryos and might be a parthenogen. Pierce (1918), when describing two species of Callipharixenos from Thailand and Ambon Island ( Indonesia), described only females.

Remarks. The second female parasitizing the mango leafhopper I. clypealis is morphologically similar to two species of female Callipharixenis muiri Pierce 1918 and C. siamensis ( Pierce 1918) from Cambodia and Thailand respectively, placed in the family Callipharixenidae Pierce (1918) . No males are known; the host of C. muiri is Calliphara billiardierei (Fabricius 1803), and that of C. siamensis is Chrysocoris grandis Thunberg 1783 ( Hemiptera : Pentatomidae ). Bohart (1941) placed Callipharixenos and Corioxenos in the family Callipharixenidae , as did Ulrich (1964) and Kinzelbach (1969). Kinzelbach (1971a) placed Corioxeninae and Callipharixeninae as separate families: Corioxenidae and Callipharixenidae . Female C. philippines sp. n. has a raised cephalothorax and round brood canal opening, whereas the brood canal openings are slit-shaped and horizontal in C. muiri and curved in C. siamensis
