Species delimitation offered by DNA-based approaches can provide important insights into the natural history and diversity of species, but the cogency of such processes is limited without multigene phylogenies. Recent attempts to barcode various Solenopsidini ant taxa (Hymenoptera: Formicidae: Myrmicinae), including the thief ant Solenopsis saudien...
We present a revised and updated synoptic list of 44 Arabian Monomorium species, including two new species of the M. salomonis species-group: M. heggyi sp. n. , and M. khalidi sp. n. We propose the following new synonyms: M. abeillei André (= M. wahibiense Collingwood & Agosti syn. n.) ; M. areniphilum Santschi (= M. fezzanense Collingwood & Agosti...
Ants of the genus Crematogaster Lund, 1831 are ecologically important and are distributed in a wide range of tropical and subtropical regions. Crematogaster dhofarensis Sharaf sp. n., a new species from Oman's Dhofar Governorate, is described based on morphological character-isation, including detailed measurements via established indices and imagi...
A new species of the genus Crematogaster Lund, 1831, C. abouzeidi sp.
nov. is described from Yemen based on the worker caste. The new species resembles
the Afrotropical C. flaviventris Santschi, 1910, thus previous records of C. flaviventris
from Yemen may be mis-identified and need to be re-examined. Crematogaster
ghoneimi Sharaf & Aldawood, 2022,...
We present the first faunal analysis of the ants (Formicidae) of the Kingdom of Bahrain (Bahrain), an island nation in the Arabian Gulf. We document a total of 35 ant species based on published, unpublished and new specimen records, including 26 presumed native species and nine non-native tramp species. The native fauna was predominantly of Palaear...
A new species, Cardiocondyla hashemi sp. n. is described and illustrated using a Scanning Electron Microscope (SEM) based on the worker caste. Cardiocondyla hash-emi is a member of the C. batesii species-group with a resemblance to C. tenuifrons Seifert, 2003 from Jordan. Cardiocondyla hashemi can be readily distinguished by the uniform yellow body...
The current study was carried out in the seaward coastal beach environment of Al-Jubail City, Saudi Arabia, to analyze the rabbit carcass decomposition process, the succession pattern of associated ants, and their potential utility in forensic investigation. Experiments were conducted over a 4-season course (from autumn 2018 to summer 2019). A tota...
The ant fauna of the Riyadh Province, Kingdom of Saudi Arabia (KSA) was studied and reviewed based on literature and newly collected material.

Objective: Termites are well known for being the most destructive pests of household commodities as well as agricultural crops around the globe. The termite fauna (Isoptera) has about 2650 described species worldwide. Several species are the pests of crops and cause damage to wood structures. Methods: In the present study, 29 specimens of termites...
Urbanization affects all elements of the pre-urban environment, including soils, hydrology, vegetation, and microclimate. Recently, Saudi Arabia has experienced rapid urbanization and growth. Thus, the country’s biodiversity has been threatened. In the Riyadh region, beetle assemblages were assessed along a rural-suburban-urban gradient. A total of...

We describe a new species, Tapinoma yacoubi sp. n., from the Al Sarawat Mountains in southwestern Saudi Arabia based on the worker caste. Tapinoma yacoubi looks similar to T. luridum Emery, 1908 from the Democratic Republic of Congo, but can be easily distinguished by its lack of setae on the frontal carinae, the convex posterior margin of the clyp...
The dramatic increased rates of uncontrolled urbanisation in various parts of the World have resulted in loss of native species and overall threats to biodiversity. Over the last few decades Saudi Arabia has witnessed a remarkably rapid population growth and unparalleled levels of urbanisation, leading to threats to biodiversity. In this study we f...
The present study shows an updated synoptic list of the 30 known Isoptera of the Arabian Peninsula which are classified under four families and nine genera.

Syllophopsis (Hymenoptera: Formicidae) is a taxonomically difficult
and possibly polyphyletic genus of tiny, inconspicuous ants.
Syllophopsis subcoeca (Emery) was described in 1894 from St
Thomas, US Virgin Islands. This remained the sole published record
of S. subcoeca for more than 100 years. Here, we present new
descriptions of the worker and qu...
Tetramorium sericeiventre Emery, 1877 is a widespread ant of Africa, Arabia, and neighbouring areas. Across its broad range, T. sericeiventre shows much variation and many different forms have been described. In the present study, we report additional site records of T. sericeiventre on the Arabian Peninsula, and provide information on species vari...
Tapinoma Foerster belongs to the ant subfamily Dolichoderinae and the vast majority of its species are arboreal or generalised foragers. The genus is composed of 70 described species, 22 known subspecies and six valid fossil species worldwide, while from the Arabian Peninsula, three species have been recorded so far.
Ants of the genus Tapinoma of t...

The genus Crematogaster is one of the most species-rich and widespread groups of ants. Despite their often-high local abundance and important ecological interactions, the taxonomy of the genus is fragmentary and in great need of modern revisionary studies. As a first step towards a revision for the Arabian fauna of Crematogaster, a review of all kn...

The Hajar Mountain Range of Northern Oman is an important centre of species endemism, and of biogeographical interest as a crossroads between the Afrotropical and Palaearctic regions. Despite this, the invertebrate fauna of the region is largely unknown, with very little dedicated research or surveys having been undertaken until now. Here we presen...
