“…The female is unable to differentiate between large and small larvae, and a long ovipositor is not necessarily an advantage because parasitization occurs inside the egg tunnel. Except for a reference by Mickel (1928), the fact that males are larger than females, as shown for Den: drosoter spp. (table 1 ), was never recorded for any hymenopterous parasitoid.…”

Information on parasitoids of bark beeries infesting conifers and broadleaves is presented to show the relations between host and parasitoid size, and parasitoid sex ratios. Sticky traps were employed to determine the sex ratios of parasitoid species operating on beetle-infested material. A wide range in body length was found for most species. Females of Cerocephala eccoptogasteri Masi, Cheiropachus quadrum Febr., Eurytoma morio Boheman, Heydenia pretiosa Forster, Metacolus unifasciatus Forster, Rhaphitelus maculatus Walker and Roptrocerus xylophagorum (Ratz.) were usually significantly longer than their maZes, whereas the males of all four Dendrosoter spp. were significantly longer than the females. Body lengths of the mazes and females were almost identical in Entedon ergias Walker and Ecphylus caudatus Rusch. The sex ratio varied markedly within most species ; the mean ratio for 5 of them differed significantly from 1:1. The sex ratio of M. unifasciatus and E. morio was significantly related to host size. The sex-ratio of parasitoids trapped on sticky traps varied with time in relation to the phenology of the host beetle. Females were more numerous during the larvae development while males were more abundant between the pupal stage and emergence of the host. Male courtship behaviour of Dendrosoter caenopachoids Rusch., D. protuberans (Nees), M. unifasciatus and R. xylophagorum is described. The effect of host size, the diversity in sex ratios, and possible interaction between parasitoid size and sex-ratio are discussed. KEY-WORDS : Hymenoptera, bark beetles, Scolytidae, parasitoid size, sex-ratio.Although hymenopterous parasitoids have received much attention from scientists engaged in research on bark beetles (e.g. Russo, 1938 ;Chararas, 1962 ; Sehvester, 1957 ;Bushing, 1965 ;Berisford et al., 1972 ;Dahlsten, 1982) little has been published about the relation between host -parasitoid size and sex ratios.Bark beetle parasitoids are usually oligophagous attacking a wide range of Scolytids and, occasionally, also other xylophagous beetles (e.g.

“…The female of. S. Iambirensis strongly resembles that of S. belokobylskiji lrlej, 1995 (from Vietnam) in having broad median depression on gastral tergum 2 and lacking true pygidial area on tergum 6, but differs therefrom in the narrow scutellar scale (wide in belokobylslriji), weak depression on tergum 2 (strong nbetokobytskiii), and smaller size (9-11 mmnbelokabylslcfi)' It also resembles those of Smicronyrme semperi (Ashmead, 1904) and S. fura Mickel, 1934 from the philippines, and S. basalis (Smith, 1879) (Fig.5).…”

“…The female of S. borneo resembles that of S. basalis annularis Mickel, 1934 (from Luzon) in having brown scape and black legs and gastral segment L, but differs therefrom in having circular pale basal spot on gastral tergum 2 (elongate in basalis annularis) and lacking broad longitudinal mediobasal depression of gastral tergum 2. The female of the new species differs from that of S. strandi (Zavattui, 1913) (from China and Thiwan) in having black legs, brown scape and circular basal spot on tergum 2 (legs and scape femrginous, and tergum 2 with an elongate spotin strandi).…”

“…I studied the female of. P. foruita (Mickel, 1934) from Mindanao (see below), which runs to P, proserpina proserpina in key, and found that it differed from the true proserpina in the more developed basal clypeal tubercle, more converging pronotal sides, and less flattened dorsum of gastral tergum 2. hobably females of P. prcserpina proserpina sensu Mickel (1934) from the Philippines are the opposit e sex of P fortuird Mckel, 1934) [NSMT].…”

Pagden,1949; Tsuneki, 1972b),but the inventry still remains quite incomplete. In1992,1993In1992, , and 1995 Dr. Seiki Yamane (Kagoshima University, Kagoshima, Japan) collected more than 100 specimens of mutillid wasps from Borneo which were entrusted to me for study. Several mutillids collected by him in Sulawesi (Celebes) and Jawa, and additional materials from other collections were also examined. Asterisks (*) show new localities.Material depositories. Institutional collections in which the examined materials will be deposited are abbreviated in the text as follows.

“…Other differences, such as body size, shape, colouration and setal patterns, often differ between sexes of the same species (Mickel 1928;Brothers 1989;Pilgrim and Pitts 2006). These traits make sex associations based on adult morphology almost impossible, and many species are known from only one sex, resulting in taxonomic problems for this group.…”
