Morphological phylogeny and revision of Sycophila and Ficomila (Hymenoptera: Chalcidoidea, Eurytomidae) associated with Afrotropical fig trees (Moraceae, Ficus).

Eurytomidae (Chalcidoidea) species associated with fig trees (Ficus) are still poorly documented. A phylogenetic analysis of 63 morphological characters was conducted to revise Afrotropical species of Sycophila Walker and Ficomila Bouek associated with fig trees. Based on our results, which also included Palaearctic species of Sycophila, three subgenera of Sycophila are proposed: Sycophila s. str., Tineomyza Rondani stat. rev. and a new subgenus, Ficorytoma subgen. n. Lotfalizadeh & Rasplus. Ficomila is maintained as a valid genus. Thirty-six species are also newly described by Lotfalizadeh & Rasplus, namely Ficomila artocarpoides sp. n., F. carolae sp. n., F. bouceki sp. n., F. comptoni sp. n., F. flava sp. n., F. gabonensis sp. n., F. gibba sp. n., F. guinensis sp. n., F. sinai sp. n., F. tanzanica sp. n., F. vannoorti sp. n., Sycophila (Tineomyza) beninensis sp. n., S. (T.) busseicola sp. n., S. (T.) glumosae sp. n., S. (T.) luteacola sp. n., S. (T.) maldesi sp. n., S. (T.) minuta sp. n., S. (T.) platygastra sp. n., S. (T.) risbeci sp. n., S. (T.) wiebesi sp. n., S. (T.) zebrogastra sp. n., S. (Ficorytoma) delvarei sp. n., S. (F.) persicae sp. n., S. (Sycophila) annae sp. n., S. (S.) bidentata sp. n., S. (S.) longiflagellata sp. n., S. (S.) chirindensis sp. n., S. (S.) ficophila sp. n., S. (S.) fusca sp. n., S. (S.) lasallei sp. n., S. (S.) macrospermae sp. n., S. (S.) meridionalis sp. n., S. (S.) nigra sp. n., S. (S.) nigriterga sp. n., S. (S.) suricola sp. n., S. (S.) zebra sp. n.. Seven described species of Sycophila are reclassified in the subgenus Tineomyza: Sycophila (Tineomyza) flaviclava Bouek, 1981; S. (T.) modesta Bouek, 1981; S. (T.) naso Bouek, 1981; S. (T.) punctum Bouek, 1981; S. (T.) ruandensis Risbec, 1957; S. (T.) sessilis Bouek, 1981 and S. (T.) setulosa Zerova, 2009. After this revision, Ficomila and Sycophila include 46 species associated with Afrotropical Ficus. Detailed morphological descriptions and illustrations as well as identification keys are provided for the subgenera, species-groups and species of Ficomila and Sycophila associated with Afrotropical fig trees; their host fig association and relative lack of host-specificity are also discussed.

An overview of the Leucospidae (Hymenoptera, Chalcidoidea) of the Arabian Peninsula with description of a new species.

An overview of the family Leucospidae (Hymenoptera, Chalcidoidea) is provided for the leucospid fauna of the Arabian Peninsula. Two genera containing four species are identified based on morphometrics and colour patterns. One species, Leucospisayezae Usman, Anwar & Ahmad, sp. nov., is described. Leucospiselegans Klug had been previously recorded from Arabia Felix (= Yemen) and is recorded here for the first time from Saudi Arabia. The status of Leucospisaff.namibica from Yemen has been clarified, and this species is placed here in the genus Micrapion Kriechbaumer as M.clavaforme Steffan. An updated key and a map showing the distribution of the family Leucospidae in the Arabian Peninsula is provided. The occurrence and color morphs of all leucospid species that have been recorded so far from the region are briefly discussed.

Potential Parasitoids for Biocontrol of the Ber Fruit Fly, Carpomya vesuviana Costa (Diptera: Tephritidae).

The ber fruit fly (BFF), Carpomya vesuviana Costa, 1854 (Diptera: Tephritidae), is an important key pest of the jujube, Ziziphus jujuba Miller. The main control measures against this pest are to use chemical control, but the first survey for its natural enemies was performed in Iran. Here, we report eight species of parasitic wasps of the BFF from five different families. The family Eurytomidae with three species, the families Pteromalidae and Mutillidae with two species each, and the families Braconidae and Diapriidae with one species each are associated with different immature stages of the BFF, of which Eurytoma pineticola Zerova (Eurytomidae) and Cyrtoptyx lichtensteini (Masi) (Pteromalidae) were the most abundant parasitoid species. Fopius carpomyiae (Silvestri,) was not reared on BFF on the jujube during this survey, but it was reported on Ziziphus spina-christi (L.) with a high parasitism rate. Therefore, it seems to be the most important parasitoid of BFF in Iran. The parasitoid community of BFF in Khorasan, Eastern Iran, is reviewed, and an identification key to these species is proposed.

Tetramesa amica and its parasitoid Eurytoma amicophaga (Hymenoptera, Eurytomidae): two new species associated with medusahead, Taeniatherum caput-medusae (Poaceae).

Medusahead, Taeniatherum caput-medusae (Poales: Poaceae), is an annual grass native to central Asia and the Mediterranean region. It is a noxious, invasive weed in much of western North America. During field explorations carried out in Greece in 2017, the new phytophagous eurytomid Tetramesa amica Lotfalizadeh, sp. nov. and its parasitoid Eurytoma amicophaga Lotfalizadeh, sp. nov., also new to science, were recorded for the first time on medusahead. These new species are described and characters that enable to recognize them from their closest relatives are summarized. Tetramesa species are generally species-specific gall-inducers. They induce damages that may have a significant impact on the physiology of infested plants by reducing the productivity of flowering heads and seed weight. Based on these data, T. amica Lotfalizadeh, sp. nov. is currently being investigated as a candidate biological control agent of medusahead.

Review of the Iranian Pteromalinae with spiculated antennae, and description of a new species of Norbanus Walker (Hymenoptera: Chalcidoidea, Pteromalidae).

Based on recently collected Pteromalidae (Hymenoptera: Chalcidoidea), 13 species were identified from genera of Pteromalinae that are characterized in part by the female clava being distinctly acuminate or apically bearing a narrow spicula. Included are two species of Callitula Spinola, three species of Homoporus Thomson, seven species of Norbanus Walker, and one species of Rhaphitelus Walker. One new species, Norbanus rasplusi n. sp., is described and six species are newly recorded from Iran: Homoporus subniger (Walker), Norbanus calabrus (Masi), N. cerasiops (Masi), N. meridionalis (Masi), N. obscurus (Masi) and N. scabriculus (Nees).

Ontogeny and reproductive biology of Diadegma semiclausum (Hym.: Ichneumonidae), a larval endoparasitoid of Diamondback Moth, Plutella xylostella (Lep.: Plutellidae).

In this article, the ontogeny and reproductive biology of Diadegma semiclausum (Hym.: Ichneumonidae), an important parasitoid of Plutella xylostella (Lep.: Plutellidae) are described in detail. We did dissect parasitized P. xylostella larvae in phosphate-buffered saline and determine the external morphology of its parasitoid at all developmental stages. The developmental duration of its immature stages, adult longevity, total oviposition period and fecundity of the parasitoid are determined at 24 ± 1 °C, 65  ±  5% R.H., and a photoperiod of 16:8 h L:D. The mean duration of egg and larval stages is 9.56 days and the prepupa and pupa stages last for 8.27 days. In average, female longevity is 1.31 times longer than that of males, and females lay 300 eggs in total. The peak of D. semiclausum oviposition is on the eighth day after mating. The egg loading pattern of D. semiclausum was investigated to determine the parasitoid 'ovigeny index' throughout the female's parasitoid lifetime. Initial egg load in immature females (<2 h age) is 1.45 per female and the mean lifetime potential fecundity (total immature and mature oocytes), at four interval ages, is 34. With an ovigeny index value of 0.038, D. semiclausum is considered moderately to strongly synovigenic. In the absence of the host, after 3 days, the number of eggs is decreased in D. semiclausum. Our results demonstrated that there is a negative relation between the ovigeny index and egg resorption in this parasitoid.
