The family Hydraenidae from Egypt is revised. As a result, 17 species belonging to the three genera: Hydraena Kugelann, 1794; Limnebius Leach, 1815 and Ochthebius Leach, 1815 and the two subfamilies: Ochthebinae and Hydraeninae are now recognized, including two new records, Hydraena arabica Balfour-Browne, 1951 and Ochthebius micans Balfour-Browne,...

Data from previous literature were used to compile a checklist of the of north African hydraenid beetles. Members of Hydraenidae are mostly 0.5-3 mm in length and genitalia of different species under the same taxonomic group are almost indistinguishable. The external morphology of several taxa, e.g., Ochthebiinae, is largely variable. Mostly all th...

The genus Atylotus Osten Sacken in Egypt is revised. A new species Atylotus shagrensis sp. nov. is described collected from Wadi Shagra (Eastern Desert). A key to species with illustrations is provided. Diagnosis, specimens examined and distributions are given for each species.

Rawdhats are unique alluvial meadows that provide a major opportunity for conservation of biodiversity in the Arabian hyper-arid regions. This study investigated the diversity and composition of the ground-dwelling beetle assemblages in two locations within Rawdhat Khorim National Park, Saudi Arabia. Beetles were collected during 24-periods from No...

Coprophagous beetles (Coleoptera: Scarabaeidae) play an important ecological role in the management of grazing and cycling of nutrients within different ecosystems. Seasonal abundance, species richness, and alpha diversity of the dung beetles were investigated in Rawdhat Khorim Nature Preserve in the central Kingdom of Saudi Arabia (KSA). Adult bee...

The first list of insects (Arthropoda: Hexapoda) of Al-Baha Province, Kingdom of Saudi Arabia (KSA) was published in 2013 and contained a total of 582 species. In the present study, 142 species belonging to 51 families and representing seven orders are added to the fauna of Al-Baha Province, bringing the total number of species now recorded from th...

Intensive sampling in Rawdhat Khorim National Park located in the central part of the Kingdom of Saudi Arabia yielded additional new country records of Curculionoidea. Twelve species of Curculionidae and one of Nanophyidae are reported for the first time from the Kingdom of Saudi Arabia.

Eleven species in three genera from Saudi Arabia are listed. Macroocula riyadha Gadallah & Pagliano, spec. nov. is described and figured. Apterogyna mateui Giner Marí, 1945, Macroocula nitida nitida (Bischoff, 1920) are newly recorded from Arabian Peninsula and Saudi Arabia, Macroocula magna (Invrea, 1965) is newly recorded from Saudi Arabia.

The "sphecid' fauna of Saudi Arabia (Hymenoptera: Apoidea) is listed. A total of 207 species in 42 genera are recorded including previous and new species records. Most Saudi Arabian species recorded up to now are more or less common and widespread mainly in the Afrotropical and Palaearctic zoogeographical zones, the exception being Bembix buettiker...

The Egyptian fauna of the genus Tabanus Linnaeus is reviewed. Only seventeen species are recognized instead of the previous 21. This is because six species have been removed as doubtful records, and an additional two species have been added (T. leucostonus Loew, 1858 (new record) and T. arenivagus Austen, 1920). A key to Egyptian species of Tabanus...

Boromophus saudicus sp. n. (subfamily Pimeliinae Latreille, 1802, tribe Boromorphini Skopin, 1978) is described from the Kingdom of Saudi Arabia (Rawdhat Khorim, Riyadh Province). This finding represents the first record of the genus Boromorphus Wollaston, 1854 from the Arabian Peninsula. The species was collected from Acacia trees and from pitfall...

A preliminary study was carried out on the insect fauna of Al-Baha Province, south-western part of Saudi Arabia. A total number of 582 species and subspecies (few identified only to the genus level) belonging to 129 families and representing 17 orders were recorded. Two of these species are described as new, namely: Monomorium sarawatensis Sharaf &...

The insect fauna of the native milkweed plant Calotropis procera (Ait.) Ait. in the Ibex Reserve, in the Central Region of the Kingdom of Saudi Arabia was studied. Insects were sam-pled bimonthly from May 2007 to late April 2008, and then irregularly until June 2011. Ninety-nine insect species belonging to eight orders, 43 families and 80 genera we...

Eleven species in three genera from Saudi Arabia are listed. Macroocula riyadha Gadallah & Pagliano, spec. nov. is de-scribed and figured. Apterogyna mateui Giner Marí, 1945, Macroocula nitida nitida (Bischoff, 1920) are newly recorded from Arabian Peninsula and Saudi Arabia, Macroocula magna (Invrea, 1965) is newly recorded from Saudi Arabia.

Studies of myremcophile insects associated with the Egyptian ant fauna indicate considerable diversity and variability. Thirteen insect orders have been recorded, Coleoptera, Homoptera, Heteroptera, Collembola, Isoptera, Diptera, Thysanura, Psocoptera, Lepidoptera, Dermaptera, Blattoidea, Hymenoptera, Embioptera. Thirty families have been recorded,...

Six new ant species from Egypt Cerapachys collingwoodi, Cataglyphis agostii, Messor eglalae, Pheidole fadli, Solenopsis bakri and Tetramorium shirlae were described.

This is the first paper of a designed series dealing with the taxonomy of Egyptian Anthicidae. The present work treated 21 species of ant-beetles genera Anhticus, Omonadus, and Stricticomus known to occur in Egypt. Keys were provided to separate the treated genera and species. All species are diagnosed and provided with detailed distribution, and s...

This study revealed that the family Scutelleridae is represented in Egypt by 23 species within 8 genera. Diagnostic characters of the family and genera, key to genera and species accompanied with illustrations are given. In addition, valid names, synonyms, world and local distribution for each species are provided. Eurygaster testudinaria (Geoffroy...

A checklist of Ceratopogonidae (Diptera) in Egypt is provided. New distributional data for 19 species from 9 localities including one new record of Leptoconops sp. 1 from Ras Muhammad (S.
