Forensic investigation of carcass decomposition and dipteran fly composition over the summer and winter: a comparative analysis of indoor versus outdoor at a multi-story building.

This study aimed to explore the rate of decomposition of rabbit carcasses and the succession pattern of the associated dipteran flies outdoor, indoor, and on the roof of a 4-story building during the summer and winter. A total of 6,069 flies were recorded, with 30.91% reported as 2 waves outdoor and on the roof in the summer and 69.09% as 4 waves outdoor in the winter. The roof showed the most flies in the summer but the least in the winter, whereas the outdoor showed the most in the winter but the least in the summer. The ground and first floors showed the most indoor flies, while the second and third floors showed the least in both seasons. Indoor carcasses decomposed slower than those outdoor, and those on the second and third floors decomposed slower than those on the ground and first floors. Ten fly species from 8 families were identified in the winter, compared to 6 from 5 families in the summer. The most abundant species was Musca domestica Linnaeus (Muscidae) on the roof in the summer, while it was Chrysomya albiceps (Wiedemannn) (Calliphoridae) outdoor in the winter. The rare species (singletons) were Musca sp. (Muscidae) and Megaselia scalaris (Loew) (Phoridae) on the first floor in both seasons, Scaptomyza pallida (Zetterstedt) (Drosophilidae) on the ground floor in the summer, and Atherigona orientalis Schiner (Muscidae) outdoor in the winter. These data highlight the variance in carcass decomposition and fly composition across outdoor, indoor, and the roof of human dwellings, which could be of forensic importance.

The ants (Hymenoptera:formicidae) of Rawdhat Khorim Nature Preserve, Saudi Arabia, with description of a new species of the genus Tetramorium Mayr.

Rawdhat Khorim, a densely vegetated alluvial basin supporting a distinctive floral community in the hyper-arid desert of central Saudi Arabia, is one of the most important protected nature sanctuaries of the country. The ant fauna (Formicidae) of Rawdhat Khorim was sampled and 14 species, including one new species were collected using a variety of sampling methods. The new species, Tetramorium saudicum sp. n., a member of the T. caespitum-group, is described based on the worker caste. Cataglyphis viaticoides (André) is recorded for the first time from Saudi Arabia. The information in this paper will allow natural resource managers to establish long-term ecological studies, using sentinel taxa such as ants to evaluate present and future impacts on Rawdhats.

New faunal data on lacewings (Insecta, Neuroptera) collected from Saudi Arabia.

This study presents new data on the lacewing fauna of Saudi Arabia based on field work performed between 2014 and 2019. Sixty-one lacewing species from 37 genera and seven Neuroptera families were documented. Additionally, two species belonging to Dielocroce and Pseudomallada were identified only to genus level. Three of the identified species are new records to Saudi Arabia (Aspoeckiella gallagheri Hölzel, 2004, Bankisus maculosus Hölzel, 1983, and Nemoleon secundus Hölzel, 2002). Another three species are new to the fauna of the Arabian Peninsula (Mantispa aphavexelte Aspöck & Aspöck, 1994, Omoleon jeanneli Navás, 1936, and Stylascalaphus krueperi van der Weele, 1909). The first reports of eight species are provided after their original description from Saudi Arabia; namely, Creoleon ultimus Hölzel, 983, Cueta amseli Hölzel, 1982, Cu. asirica Hölzel, 1982, Distoleon asiricus Hölzel, 1983, Geyria pallida Hölzel, 1983, Neuroleon delicatus Hölzel, 1983, N. virgineus Hölzel, 1983 and Solter buettikeri Hölzel, 1982 Zoogeographically, most lacewing species documented in the Arabian Peninsula are endemic (26.2%), followed by Afro-syroeremic (23.0%), Afrotropical (18.0%), and Afro-syro-iranoeremic (14.8%) species. Palaearctic species (4.9%) had the lowest contribution.

The family Oestridae in Egypt and Saudi Arabia (Diptera, Oestroidea).

All known taxa of the family Oestridae (superfamily Oestroidea) in both Egypt and Saudi Arabia are systematically catalogued herein. Three oestrid subfamilies have been recorded in Saudi Arabia and/or Egypt by six genera: Gasterophilus (Gasterophilinae), Hypoderma, Przhevalskiana (Hypodermatinae), Cephalopina, Oestrus, and Rhinoestrus (Oestrinae). Five Gasterophilus spp. have been recorded in Egypt, namely, G. haemorrhoidalis (Linnaeus), G. intestinalis (De Geer), G. nasalis (Linnaeus), G. nigricornis (Loew), and G. pecorum (Fabricius). Only two of these species have also been recorded in Saudi Arabia, namely: G. intestinalis (De Geer) and G. nasalis (Linnaeus). The subfamily Hypodermatinae is represented in the two countries by only four species in two genera, namely, H. bovis (Linnaeus) and H. desertorum Brauer (in Egypt only), and H. lineatum (Villers) (in Saudi Arabia only) and Przhevalskiana silenus (Brauer) (in both countries). The subfamily Oestrinae is represented by two widely distributed species in both countries, namely, C. titillator (Clark) and O. ovis (L.), in addition to another species represented in Egypt only, R. purpureus (Brauer). For each species, synonymies, type localities, distribution, Egyptian and Saudi Arabian localities with coordinates, and collection dates are presented.

Biting midges of Egypt (Diptera: Ceratopogonidae).

BACKGROUND: This study is one in a series of planned studies on different Egyptian dipteran taxa aiming to catalogue the whole order in Egypt. NEW INFORMATION: All known Egyptian taxa of the family Ceratopogonidae (biting midges) are systematically catalogued. A total number of 64 species belonging to 11 genera, four tribes and four subfamilies has been treated. Data for this study have been compiled from both available literature and specimens collected from different Egyptian localities by the authors. An updated classification, synonymies, type localities, world distributions by biogeographic realm(s) and country, Egyptian localities and dates of collection are provided comprising some new locality records. The study treats all previous inaccuracies in the classification of the family in Egypt.

The first survey of the beetles (Coleoptera) of the Farasan Archipelago of the southern Red Sea, Kingdom of Saudi Arabia.

The Farasan Archipelago is a group of small coral islands and islets in the southern Red Sea, offshore of the southwestern Kingdom of Saudi Arabia (KSA). These islands are internationally important as breeding sites for turtles and bird species and regionally for its threatened, rare, and endemic flora and other fauna. The beetles (Coleoptera) of the Archipelago have not been previously surveyed. This study presents the first data on the beetle fauna based on a recent survey of the Farasan Archipelago. In total, 179 beetle species (including three synanthropic species) in 145 genera and 31 coleopteran families were determined. The Carabidae are represented by 31 species, followed by the Tenebrionidae (22 species), Chrysomelidae (17 species), Scarabaeidae (13 species), and Coccinellidae (12 species). The genus Lasiocera Dejean, 1831 and the species Amblystomus villiersanus Bruneau de Miré, 1991 (Carabidae) are new for the beetle fauna of the Arabian Peninsula, and eighteen species are new country records for KSA. Sand dune habitats on the islands were inhabited by the greatest number of species in comparison with other habitats. Zoogeographically, the beetle fauna of the Archipelago was dominated by the representatives of the Saharo-Arabian and Afrotropical elements (74 spp., 41.0%). Fourteen species (7.8%) were recognized as cosmopolitan and subcosmopolitan. No species was known to be exclusively endemic to Farasan Archipelago. Eighteen species (10.1%) were endemic to Arabian Peninsula and KSA. Approximately 64.8% (116 spp.) of the archipelago beetle species is found on the KSA mainland and is most closely allied to the south and southwestern KSA regions (sharing 91 spp.). Comparisons of the beetle faunas of the Farasan and Socotra archipelagos indicate that 30 families, 70 genera, and 28 species are shared.

On the taxonomy of the genus Thyridanthrax Osten Sacken in Egypt and the Kingdom of Saudi Arabia, with description of a new species (Diptera: Bombyliidae).

Egyptian and Saudi Arabian Thyridanthrax spp. collected in field trips or preserved in the Efflatoun's insect collection in Cairo University were taxonomically studied. One new species, T. elegansoides sp. nov., is herein described, and two species, T. decipulus (Austen) and T. polyphemus (Wiedemann), are newly recorded from Egypt. Ten species are treated: one species from the Kingdom of Saudi Arabia, T. anomalus Greathead; two species from Egypt and the Kingdom of Saudi Arabia, T. decipulus (Austen) and T. perspicillaris (Loew); and seven species from Egypt: T. elegans (Wiedemann), T. elegansoides sp. nov., T. griseolus (Klug), T. incanus (Klug), T. lotus (Loew), T. obliteratus (Loew), and T. polyphemus (Wiedemann). Taxonomic comments, an identification key to species, diagnoses, and photographs of some species and genitalia are provided. Based on wing morphology and male genitalic characters, T. lotus clearly does not fit in the genus Thyridanthrax, and may need to be placed elsewhere, nevertheless it is not clear whether it can be included in any of the other currently recognized genera in the tribe Villini. It is here kept in Thyridanthrax until a more rigorous study can be conducted to better ascertain its position in the Villini.

The Carabidae (Coleoptera) of Shada Al-A'Ala Nature Reserve, Southwestern Saudi Arabia, with description of a new species of Paussinae.

We report the Carabidae collected at the Shada Al-A'Ala Nature Reserve (SANR) in Baha Province in southwestern Saudi Arabia during 2013-2015. In total, 62 carabid species and subspecies representing 39 genera, 17 tribes, and 10 subfamilies were identified, including one new species, Paussusminutulus Nagel & Rasool, sp. n, four new country records, and 24 species that are new provincial records for Baha. The carabid fauna was dominated by the Lebiini with 19 species. A high number of species were rarely collected (34 species) in comparison to the more abundant and common species (9 species). The highest number of species (52 species) was collected during autumn. The carabids of SANR are represented by a large component of Afrotropical faunal elements (28.1%) and smaller numbers of Oriental species (3.5%) and endemic taxa (5.3%). In comparison to Garf Raydah Nature Reserve in Asir Province, also in southwestern Saudi Arabia, SANR had an equal number of carabids sharing 64.5% of the species but with lower number of endemic elements. Our study can serve as a component for implementing a conservation plan for SANR using carabid beetles as sentinel taxa. These research results may support future ecological studies on SNAR carabids.

Faunistic inventory and zoogeographical analysis of the ground beetles (Coleoptera, Carabidae) of Garf Raydah Nature Reserve, Southwestern of Saudi Arabia, and description of a new species of Paussinae.

Study of ground beetles of the Garf Raydah Nature Reserve, located in the Asir Mountains of southwestern Kingdom of Saudi Arabia (KSA) resulted in one species, Paussus abditus Nagel, sp. n. described as new to science. Thirteen species (21.3%) are reported as new country records and fifteen species (24.6%) are new records for Asir Province. Adult beetles were collected from 2013 to 2017. The determination of this material yielded a total of 61 species in 40 genera and 17 tribes belonging to nine subfamilies of Carabidae. The species richness represented approximately 36.1% of carabid species previously reported from KSA. The most species rich tribes were the Lebiini (20 species), the Harpalini (10 species), and the Bembidiini (6 species). The life form analysis of adults indicated 18 life form types that are grouped into three categories, Zoophagous (77.1%), Mixophytophagous (18.0%), and Myrmecophilous (4.9%). Zoogeographical analyses indicated that the Afrotropical (19.3%) and the Saharo-Arabian (19.3%) species dominate the carabid fauna of this region of KSA. Coryza cf. maculata (Nietner, 1856) is considered the only Oriental representative. Only one cosmopolitan species, Perigona nigriceps (Dejean, 1831), was collected. Eleven endemics were identified; six species are considered KSA endemics and five are Arabian Peninsula endemics.

The Dromiusina Bonelli, 1810 of southwestern Saudi Arabia with description of a new species (Coleoptera, Carabidae, Lebiini).

In this paper, species of the subtribe Dromiusina Bonelli, 1810 from southwestern Saudi Arabia are revised. Eleven species in six genera (Calodromius, Dromius, Mesolestes, Metadromius, Microlestes, and Zolotarevskyella) are recognized. Dromius saudiarabicus Rasool, Abdel-Dayem and Felix, sp. n. is newly described species from Rayda Nature Reserve Asir province. The presence of Metadromius ephippiatus in Saudi Arabia is doubtful. A key is also provided to genera and species level for Dromiusina of Saudi Arabia.

A review of the Subtribe Lebiina Bonelli (Lebiini, Carabidae, Coleoptera) from Southwest of Saudi Arabia.

In this paper, descriptions, illustrations, distributional maps and a key for the subtribe Lebiina Bonelli, 1810 of Lebiini are presented for the two genera, Lebia Latreille, 1802 and Matabele, Peringuey, 1896 and six species from the southwest of Saudi Arabia. Lebia raeesae sp. n is described as a new species, L. melanacra (Chaudoir, 1878) and L. melanura (Dejean, 1831) are new records to the fauna of the country. Thus, the Saudi fauna of Lebiina based on this study has increased from three to six species.

A review of subtribe Cymindidina Laporte, 1834 (Coleoptera: Carabidae: Lebiini) in Southwestern Saudi Arabia, with descriptions of two new species.

The carabid subtribe Cymindidina Laporte, 1834 is reviewed for the southwestern Saudi Arabia. Five species belonging to two genera (Afrotarus Jeannel, 1949 and Cymindis Latreille, 1806) are studied, including two species described as new: A. fadli sp. n. from Baha Province and A. soudaensis sp. n. from Asir Province. A key to genera and species of Saudi Arabia is given.

The beetle fauna (Insecta, Coleoptera) of the Rawdhat Khorim National Park, Central Saudi Arabia.

This study was conducted as a part of a comprehensive baseline survey of insect biodiversity of Rawdhat Khorim National Park (RKNP), Central Kingdom of Saudi Arabia (KSA). During this study a total of 262 Coleoptera species belong to 182 genera in 35 families were identified, of which 247 are named at a species level. Fifteen species (6.0%) are apparently endemic to KSA. Thirty-eight species are new to the known beetle fauna of KSA, including 25 species reported from the Arabian Peninsula for the first time. The families Tenebrionidae (45 species), Scarabaeidae (34 species), and Carabidae (27 species) were the most species rich families. About 37% of the beetle abundance was represented by species of Scarabaeidae, especially Aphodius ictericus ghardimaouensis Balthasar. Karumia inaequalis Pic (Dascillidae) was also an abundant species. Approximately 43.5% of beetle species collected during this study are considered very rare taxa in RKNP. The RKNP beetle fauna shows more affinity to Sahro-Arabian (36.4%), Afrotropical-Sahro-Arabian (17.4%) and Palaearctic-Sahro-Arabian (10.5%). Twenty-three species (9.3%) are considered cosmopolitan or subcosmopolitan. The data on month of collection, method of collection, and abundance status within RKNP, together with the distribution within KSA and the general distribution (zoogeography) of each species are presented.

A preliminary account of the fly fauna in Jabal Shada al-A'la Nature Reserve, Saudi Arabia, with new records and biogeographical remarks (Diptera, Insecta).

The first list of insects of Al-Baha Province, Kingdom of Saudi Arabia (KSA) was published in 2013 and contained a total of 582 species; an addendum to this list was published in 2015 adding 142 species and bringing the total number recorded from the province to 724 insect species representing 17 orders. The previous two studies excluded Jabal Shada al-A'la Nature Reserve (SANR), so the present study in SANR, as belonging to Al-Baha Province, are complementary to the previous two. The present study presents a preliminary list of Diptera (Insecta) in SANR, with remarks on their zoogeography, and is the first of a series of planned ecological and systematic studies on different insect orders as one of the outputs of a project proposed to study the entire insect fauna of SANR. A total number of 119 Diptera species belonging to 87 genera, 31 tribes, 42 subfamilies, and representing 30 families has been recorded from SANR in the present study. Some species have been identified only to the genus level and listed herein only because this is the first time to record their genera in KSA. Fourteen of the species are recorded for the first time for KSA, namely: Forcipomyia sahariensis Kieffer, 1923 [Ceratopogonidae]; Chaetosciara sp. [Sciaridae]; Neolophonotus sp.1; Neolophonotus sp.2; Promachus sinaiticus Efflatoun, 1934; Saropogon longicornis (Macquart, 1838); Saropogon sp. [Asilidae]; Spogostylum tripunctatum (Pallas in Wiedemann, 1818) [Bombyliidae]; Phycus sp. [Therevidae]; Hemeromyia sp.; Meoneura palaestinensis Hennig, 1937 [Carnidae]; Desmometopa inaurata Lamb, 1914 [Milichiidae]; Stomoxys niger Macquart, 1851 [Muscidae]; and Sarcophaga palestinensis (Lehrer, 1998) [Sarcophagidae]. Zoogeographic affinities of recorded fly species suggest a closer affiliation to the Afrotropical region (46%) than to the Palearctic region (23.5%) or the Oriental region (2.5%). This supports the previous studies' conclusions and emphasizes the fact that parts of the Arabian Peninsula, including Al-Baha Province, ought to be a part of the Afrotropical Region rather than of the Palaearctic Region or the Eremic Zone.

Ecological niche modeling and land cover risk areas for rift valley fever vector, culex tritaeniorhynchus giles in Jazan, Saudi Arabia.

BACKGROUND: The mosquito, Culex tritaeniorhynchus Giles is a prevalent and confirmed Rift Valley Fever virus (RVFV) vector. This vector, in association with Aedimorphus arabiensis (Patton), was responsible for causing the outbreak of 2000 in Jazan Province, Saudi Arabia. METHODOLOGY/PRINCIPAL FINDINGS: Larval occurrence records and a total of 19 bioclimatic and three topographic layers imported from Worldclim Database were used to predict the larval suitable breeding habitats for this vector in Jazan Province using ArcGIS ver.10 and MaxEnt modeling program. Also, a supervised land cover classification from SPOT5 imagery was developed to assess the land cover distribution within the suitable predicted habitats. Eleven bioclimatic and slope attributes were found to be the significant predictors for this larval suitable breeding habitat. Precipitation and temperature were strong predictors of mosquito distribution. Among six land cover classes, the linear regression model (LM) indicated wet muddy substrate is significantly associated with high-very high suitable predicted habitats (R(2) = 73.7%, P<0.05). Also, LM indicated that total dissolved salts (TDS) was a significant contributor (R(2) = 23.9%, P<0.01) in determining mosquito larval abundance. CONCLUSION/SIGNIFICANCE: This model is a first step in understanding the spatial distribution of Cx. tritaeniorhynchus and consequently the risk of RVFV in Saudi Arabia and to assist in planning effective mosquito surveillance and control programs by public health personnel and researchers.
