ABSTRACT. Diagnosis of the genus Neoplatycerus Subba Rao, 1965, key to females of 4 known species and synopsis of them are provided. N. tshernyshevi sp.n. is described from Australia. with clearly (Fig. 1) or slightly (Fig. 3) curved ventral margin; dorsal outer flange of scape well developed; pedicel subtriangular; funicle 6=segmented, all its segments strongly transverse. Mandible with 2 teeth at apex. Maxillary palpus 4=segmented, labial palpus 3=segmented. Pronotum short. Mesoscutum without parapsidal lines. Wings not abbreviated; marginal vein of the forewing punctiform, stigmal vein strongly curved, postmarginal vein as long as or a little shorter than stigmal. Gaster with ovipositor sheaths not exerted; paratergites present in the type species. Body length 1.3 2.3 mm. Male (not known for N.tachikawai and N. tshernyshevi). Antennae (Fig. 2) not enlarged foliaceously, with scape slightly or moderatory broadened; all funicular segments somewhat wider than long, or 1st segment subquadrate; clava entire, not truncate. BIOLOGY. Endoparasitoids of mealybugs (Homoptera: Pseudococcidae), other data require confirmation. DISTRIBUTION. Israel, Egypt, India, Malaysia, Australia. Materials from Malaysia were not identified to species [Noyes & Hayat, 1984: 306307]. SYSTEMATIC POSITION. Genus Neoplatycerus belongs to subfamily Tetracneminae, tribe Chrysoplatycerini, subtribe Chrysoplatycerina. It is closely related to the genus Ceraptrocerella Girault, 1918, known only from Australia. Neoplatycerus differs from Ceraptocerella in robust body (flatened in Ceraptocerella), absence of transverse band of dense white setae above the frontofacial ridge, absence of dark pattern on the forewing.

РЕЗЮМЕ. Статья содержит диагноз рода Neoplatycerus Subba Rao, 1965, определительную таблицу самок 4 его известных видов и их синопсис. Описан N. tshernyshevi sp.n. из Австралии.

Introduction
Neoplatycerus tshernyshevi sp.n. was found by me in the collections of the University of California (Riverside, USA) during my visit there in 1997. Previously described species of Neoplatycerus are primary endoparasitoids of mealybugs (Homoptera: Pseudococcidae) including those injurious to such important cultivated plants as grapes (Vitis vinifera), mango (Mangifera indica) and pomegranate (Punica granatum). They might be used in programs of classical biological control and integrated pest management. Earlier the genus Neoplatycerus was not indicated for Australia. Genus Neoplatycerus Subba Rao, 1965

(Punica granatum), ,but now such identificftion of the host might be questionable, because there exists in Israel a similar species Planococcus ficus Signoret. In 2002, Prof. Yair BenDov (Rehovot, Israel) sent to me and to my son and co-author Dr. Serguei V. Triapitsyn a message and informed us that in 1987 he sent a material of N.palestinensis to Dr. John S. Noyes (London) who confirmed this identification. Ben-Dov determined then the mealybug host as Ferrisia virgata Cockerell, but in 2002 wrote that it was a misidentification, and the true name of this pseudococcid host is F. malvastra Mc Daniel (pers. comm.).

Synopsis of species
1. Neoplatycerus kemticus V. Trjapitzin et S. Triapitsyn (Figs 12).
DISTRIBUTION. Egypt, ex Planococcus ficus Signoret and Planococcus sp. on grapes (Vitis vinifera).
Trjapitzin & Triapitsyn, 2002: 205208.

3. Neoplatycerus tachikawai Subba Rao, 1965.
DISTRIBUTION. India, ex Rastrococcus icerioides Green on mango (Mangifera indica). Indication of rearing of N. tachikawai from Iceria seychellarum Westwood (Homoptera: Margarodidae) is doubtful. A brief review of encyrtid genera connected with Margarodidae was published by Trjapitzin & Triapitsyn [2006].

Rivnay, 1945: 119121 (Tropidophryne sic!); 1960: 224. (Tropidophryne, but probably the species belong to a new genus); 1968: 55 (Tropidophryne) Trjapitzin, 1971: 68 (not Tropidophryne); Kerrich, 1978: 150 (Tropidophryne, but a further assessment of the generic position of the species may be made); Trjapitzin, 1989: 125; Trjapitzin & Triapitsyn, 2002: 204, 208209.

4. Neoplatycerus tshernyshevi Trjapitzin sp.n. Fig. 3.
TYPE MATERIAL. Holotype female : Australia, SE Qld [ Southeast Queensland], Gatton, 11. IX. 1980 (Gordh & Dahms); Neoplatycerus, det. V. A. Trjapitzin, 1997. The intact holotype specimen is card-mounted. Paratype female: the same labels as by the holotype; the specimen is card-mounted, with one antenna lost, another and left forewing detached and mounted on the slide ? 2 Сal. in Canada balsam. Both holotype and paratype are preserved in the Entomology Research Museum, University of California, Riverside, USA.

DISTRIBUTION. Israel. NOTE. The question concerning hosts of Neoplatycerus palestinensis is not simple, because data on them are rather contradictory. Rivnay [1945] indicated as a host of this species Eriopeltus sp. (Homoptera: Coccidae) on a 'composite thistle' in Jerusalem. Without any doubt it was an error of rearing of the parasitoid; Encyrtidae of the subfamily Tetracneminae infest among coccoids only pseudococcids and eriococcids. In Rehovot , N. palestinensis was reared from the citrus mealybug Planococcus citri Risso on pomegranate

DESCRIPTION. Female (holotype and paratype). Head, seen from above, wider than long (19 : 15). Occipital margin slightly concave, sharp. Inner orbits of eyes diverging anteriorly. Vertex about 3/8 head width; frontovertex, measured

Fore legs brownish black or black, including tarsi. Mid and hind legs dark, with mid femora brown. Mesotibial spur yellow. Mid and hind tarsi white-yellow or yellow-white.

DIAGNOSIS. Neoplatycerus tshernyshevi sp.n. is the only representative of the genus Neoplatycerus with antennal scape of female not narrowed strongly in basal part (Fig. 3). In all other described species of the genus scape is basally narrowed (Fig. 1). ACKNOWLEDGMENTS. I am thankful to Dr. Alejandro Gonzбlez Hernбndez (Universidad Autуnoma de Nuevo Leуn, Monterrey, Mйxico) for preparation of computer images images of some body parts of the paratype of Neoplatycerus tshernyshevi sp.n. from which drawing was made by me.
