Contribution to the Ichneumoninae (Hymenoptera: Ichneumonidae) of Iran,with descriptions of three new species

In this faunistic survey, we give distributional records for 48 species and subspecies of Ichneumoninae found in Iran, mainly from Golestan and Azerbaijan-e-Grabi provinces. 13 of these taxa are new for the Iranian fauna. Three Iranian species are new to science and described and illustrated, namely Coelichneumon iranicus Riedel sp. n., Coelichneumon melanocastaneus Riedel sp. n., and Coelichneumon nigrifrons Riedel sp. n.

Evolutionary history of the Persian Jird,Meriones persicus,based on genetics,species distribution modelling and morphometric data

The Persian Jird, Meriones persicus, is distributed from Eastern Anatolia to Afghanistan and western Pakistan. Six subspecies were described based on skull features and coat colours, but the validity of these subspecies is uncertain, and no molecular work has ever been conducted on this species. Iran appears to be a key geographical region in which to revise the systematic and evolutionary history of this species, because five of the six subspecies are present in this country. To evaluate the phylogeographical history and taxonomy of this species in Iran, we used a combination of genetic (cytochrome b gene sequences of 70 specimens) and geometric morphometric (2D landmarks on the ventral side of skull of 258 specimens) analyses. We also used ecological niche modelling to make inferences about the evolutionary history of these lineages. Our molecular data highlight the existence of four genetic lineages, but they only partly correspond to the previously described subspecies. Our molecular and morphometric data confirm the validity of M. p. rossicus and show that it has a wider geographical range than previously thought. M. p. gurganensis and M. p. baptistae are genetically very close. The skull of M. p. gurganensis is morphologically distinguishable from other subspecies. The subspecies M. p. persicus and M. p. baptistae are genetically distinct, but morphologically close. Meriones p. ambrosius is genetically close to M. p. persicus, and additional analyses with more specimens are needed to validate its subspecific status. The genetic structure observed in Iran seems to fit the topography and biogeography of the country and emphasize the role of the Abarkooh, Central and Lut deserts as barriers to gene flow. All intraspecific divergent events within the Persian Jird occurred during the last 1.4 My, suggesting that climatic changes probably trigger diversification within this species. Our genetic and species niche modelling results suggest that potential refugial areas persisted during glacial periods for this species in north‐western Zagros Mountains, north‐eastern Alborz Mountains and Kohrud Mountains.     

New data on the spider fauna of Iran (Arachnida: Araneae)

We present the results of some spider surveys that were conducted in different parts of Iran. Faunistic records for 30 species which are new to Iran are presented here. Biogeographic data are provided for each species. Two families, namely Liocranidae and Mimetidae, are recorded for the first time from the country.     

Labiatae Novae Iranicae

Four new species are described:Lavandula sublepidota, from S. Iran (related toL. coronopifolia),Phlomis pachyphylla from S. Iran, Prov. Fars (nearPh. polioxantha),Satureia isophylla from N. Iran, Prov. Mazanderan (close toS. mutica andS. intermedia), andThymbra neurophylla from Iraqi Kurdistan (distinct forth species of the genus).

First report of c. 1499G>C mutation in a 6-month-child with cystic fibrosis

So far, more than 1800 mutations identified in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. In this case report, we presented first report of c. 1499G>C mutation in a 6-month-old girl with cystic fibrosis (CF) diagnosis. A 6-month-old girl with weakness and meconium Ileus referred to the pediatric clinic in Ilam, in the west of Iran. Patient''s skin was dark and suffered from bronchiectasis. The sweat test was performed, and the concentration of chloride and sodium in patient''s sweat was 130-135 mmol/L and 125-128 mmol/L, respectively. The exon 10 mutation analysis of a CF patient was performed. CFTR mutation analysis revealed the identification of 2 mutations in patient, the mutations were p.F508del (ΔF508) and c. 1499G>C (cd500), respectively. The mutation c. 1499G>C (cd500) were found for the first time in the world. Assessing this mutation in future study and genetic investigation is recommended.     

Evaluation of bacterial antagonists of Ralstonia solanacearum,causal agent of bacterial wilt of potato

Bacterial wilt of potato caused by Ralstonia solanacearum is one of the most destructive diseases in Kurdistan province, Iran. The objective of the present study was to evaluate antagonistic effects of some rhizobacteria isolated from the rhizosphere of potato plants against R. solanacearum, the agent of potato bacterial wilt. A total of 52 rhizobacteria were isolated and screened for in vitro antagonistic activity against R. solanacearum. Seven isolates with inhibiting effects of the pathogen were identified by phenotypic properties and partial sequencing of 16s rRNA as Pseudomonas fluorescens Pf11, P. fluorescens Pf16, Pseudomonas putida Pp17, Paenibacillus sp. Pb28 and Enterobacter sp. En38, Pseudomonas fluorescens Pp23 and Serratia sp. Se40. Strains Pf11, Pf16, Pp17 and Pb28 significantly inhibited the growth of the pathogen. Strains En38, Pp23 and Se40 showed a moderate or weak inhibition. During greenhouse study, strains were evaluated for their effects in reducing of disease and increasing biomass of potato plants. In according to greenhouse experiment results, isolates Pb28, Pp17 and Pf11significantly reduced disease by 55.56%, 51.50% and 38.58%, respectively. In addition, plant biomass significantly increased in plants treated with Pb28, Pp17, Pf11 and Pf16, compared to the control. Therefore, this study shows that these four strains have potential to be used as biocontrol agents against R. solanacearum. To confirm their effectiveness as commercial biocontrol agent, it is necessary to evaluate their efficiency in the field conditions in the next studies.     

Seasonal variation of Leishmania major infection rates in sandflies from rodent burrows in Isfahan province, Iran

Abstract. In preparation for field trials of killed Leishmania major vaccine, natural infections with Leishmania promastigotes were monitored in Phlebotomine sandfly vectors from villages of Borkhar rural district, northeast of Isfahan in central Iran, where Lmajor zymodeme MON-26 (=LON-l) has been identified as causing zoonotic cutaneous leishmaniasis (ZCL). Sandflies were collected and dissected weekly, from burrows of rodent colonies, during the 'sandfly season', June-October 1991. Leptomonad infection rates were 12% of 26 Phlebotomus ansarii , 8% of 280 P.caucasicus , 11 % of 1042 P.papatasi and none of 126 Sergentomyia sintoni , being greatest during late August through September, coinciding with peak activity of the sandflies, 2–3 months before the highest incidence of ZCL human cases in November-December.     

Sexual size dimorphism in Darevskia raddei (Sauria: Lacertidae) from northwestern Iran

We examined sexual size dimorphism of the rock-dwelling lizard Darevskia raddei (Boettger, 1892) with the help of 30 specimens that were provided from various sources. Eleven metric and seven meristic features were examined. Seven characters (gulars, length of basal tail, femoral pores, length of head, width of head, length of fore limb and length of hind limb) were identified as dimorphic between the two sexes. Some of these characters have important roles in copulation for males, especially the hind limb and the tail base. The number of femoral pores is important in the release of signal components because females release these components to attract males during the mating season. The length of the hind limb as locomotor performance plays an important role during mating, so that the male can grasp the female and adopt the correct position during copulation.     

Litho- and biostratigraphy of the Upper Jurassic Mozduran Formation,Kopet-Dagh,Iran, and its paleoenvironmental implications

The Upper Jurassic Mozduran Formation at Baghak section, Kopet-Dagh area northeast Iran, characterized by multiple units of carbonates and evaporates intercalated with siliciclastic deposits, yielded benthic foraminifera, calcareous algae, and crustacean coprolites, including Alveosepta jaccardi, Charentia aff. nana, Deloffrella quercifoliipora, Marinella cf. lugeoni, Favreina, and Solenopora sp. The almost consistent occurrence of Alveosepta jaccardi in the studied section, i.e., the Alveosepta jaccardi Zone, indicates late Oxfordian to the Kimmeridgian in age. Facies analysis of the formation reveals depositional settings of a peritidal zone, a lagoon, and a high-energy shoal of a carbonate ramp. Terrigenous and evaporites are found in eastern parts of Kopet-Dagh, representing a more proximal sedimentary environment. These siliciclastic inputs are associated with tectonic events during Oxfordian to Tithonian in the region.
