HEAD. Longer than broad in frontal view (CI 79), lateral margins converge anteriorly and posteriorly; posterior margin weakly concave in middle; antenna 12-segmented; scapes large, clavate, when laid back from their insertions fail to reach posterior margin of head (SI 75–78); eyes prominent, situated about at midline on head sides (EL 0.17–0.20, IOD 0.39–0.42); median lobe of clypeus protruding forwards, with a weak submedian carinae; mandibles triangular, with masticatory margin armed with 4–5 prominent teeth. Mesosoma slender (WL 0.74–0.75); in profile, mesosoma forming almost a continuous arch; metanotal groove weakly impressed; humeri in dorsal view rounded; propodeal spines long and sharp with acute tips (PSLI 33–35), slightly longer than distance between their bases; metafemur much longer than wide in dorsal view (HFL 0.61–0.62, HFW 0.11–0.12). Petiole node highest anteriorly, with a slightly concave anterior face and flat dorsum, sloping downwards to the posterior face; subpetiolar process reduced. Postpetiole node rounded in profile and trapezoidal in dorsal view. Gaster ovate, smooth and shiny; basal half of first tergite slightly roughened, becoming increasingly shiny and weakly sculptured. HEAD AND BODY. Uniformly pale brownish yellow to light brown, head and gaster slightly darker. Head, median lobe of clypeus and supraclypeal area, smooth and shiny; longitudinal rugae distinct over cephalic surface in full-face view; mesosoma weakly reticulate-rugolose. Petiole and postpetiole nodes dull and finely reticulate, without much rugae. Vertex, frons and frontal lobes with few erect hairs; clypeus with a single erect hair on each side of median lobe in addition to usual long curled hairs along anterior margin. Erect hairs also present throughout mesosoma; petiole and postpetiole with several erect hairs which are longer than mesosomal pilosity; all gastral tergites with scattered short, erect or suberect hairs. Ecology The holotype and a single paratype specimen were collected in a pitfall trap set in the Asir Mountains. Other paratype specimens were collected by sifting soil from litter samples taken under a palm tree Hyphaene thebaica (L.) Mart. (Arecaceae) in the provinces of Jizan and Al Bahah in Saudi Arabia. Remarks The new species is a member of the T. laurae (Prebus, 2015) species group of the Afrotropical Region. Among the poorly known species from the region, T. arabicus sp. nov. seems to have affinities with T. mpala Prebus, 2015 from Kenya. The two species can be easily differentiated through a combination of characteristics. T. arabicus sp. nov. = head longer than broad (CI 79), lateral margins strongly converge anteriorly and posteriorly, smaller propodeal Spine Index (PSLI 33–35), clypeus smooth and shiny without any prominent median or longitudinal rugae, cephalic dorsum with feeble longitudinal rugae and pilosity prominent; whereas T. mpala = head subrectangular, longer than broad (CI 72–76), lateral sides parallel, slightly converging towards the mandibular insertions, higher propodeal Spine Index (PSLI 25–27), clypeus with strongly developed median ruga and much more prominent longitudinal rugae, cephalic dorsum reticulate, and pilosity sparse. The two species differ considerably in morphometrics as well (in T. arabicus sp. nov., PTL 0.14–0.15; PTH 0.20–0.21; PTW 0.12–0.13 compared with PTL 0.20–0.23; PTH 0.19–0.22; PTW 0.16–0.17 in T. mpala) and postpetiole (in T. arabicus sp. nov., PPTH 0.15–0.16; PPTL 0.14–0.15; PPTW 0.21–0.23 compared with PPTH 0.17–0.18; PPTL 0.12–0.15; PPTW 0.22–0.24 in T. mpala).Published as part of Sharaf, Mostafa R., Akbar, Shahid A., Al Dhafer, Hathal M., El-Gharbawy, Ali & Aldawood, Abdulrahman S., 2017, Taxonomy of the Myrmicine ant genus Temnothorax Mayr, 1861 (Formicidae: Myrmicinae) in the Arabian Peninsula, pp. 1-17 in European Journal of Taxonomy 280 (280) on pages 4-6, DOI: 10.5852/ejt.2017.280, http://zenodo.org/record/382463
DAT: Data Architecture Modeling Tool for Data-Driven Applications
No full textData is the key to success for any Data-Driven Organization, and managing it is considered the most challenging task. Data Architecture (DA) focuses on describing, collecting, storing, processing, and analyzing the data to meet business needs. In this tool demo paper, we present the DAT, a model-driven engineering tool enabling data architects, data engineers, and other stakeholders to describe how data flows through the system and provides a blueprint for managing data that saves time and effort dedicated to Data Architectures for IoT applications. We evaluated this work by modeling five case studies, receiving expressiveness and ease of use feedback from two companies, more than six researchers, and eighteen undergraduate students from the software architecture course
Enhancing Sharaf Mastery Through Ristek Muslim Digital Dictionary and Google Classroom Among Arabic Language Students
No full textThis study contributes significantly to the development of Sharaf learning by introducing an innovative approach using the Ristek Muslim digital dictionary. The guidelines developed in this research provide Arabic language students with an accessible and effective tool to improve their understanding of Sharaf, a crucial component of Arabic grammar. This study enhances student engagement and learning outcomes by integrating digital resources into Sharaf\u27s instruction. The positive feedback from students, material experts, and media experts highlights the value of these guidelines in improving both the content and delivery of Sharaf lessons. Furthermore, the T-test results demonstrate the effectiveness of the digital dictionary guidelines in fostering a more profound comprehension of Sharaf concepts. This contribution supports the modernization of Arabic language teaching, offering a more interactive and efficient way for students to master the intricacies of Sharaf. The findings suggest that integrating digital tools in Arabic language learning, particularly in the study of Sharaf, can contribute to better learning outcomes. Additionally, based on the Borg and Gall model, the development process successfully addressed potential challenges and refined the product through multiple stages of testing and validation. Overall, this study demonstrates that the Ristek Muslim digital dictionary guidelines are a valuable resource for improving Sharaf learning and can be a model for integrating digital technology into Arabic language educatio

HEAD. Slightly longer than broad and broader anteriorly than posteriorly, with emarginated posterior margin and feebly convex sides; anterior clypeal margin nearly straight or feebly convex; eyes large (EL 0.31–0.36 × HW), with 11 ommatidia in longest row; scapes when laid back from their insertions surpassing posterior margin of head by about one third of eye length. MESOSOMA. Promesonotum distinctly convex in profile; metanotal groove impressed. PILOSITY. Underside of head with few short straight hairs, not forming a psammophore; cephalic surface and mandibles with sparse short hairs, anterior clypeal margin with a median long hair and two pairs of long hairs on each side; antennae with dense appressed pubescence; mesosoma without hairs except for few sparse appressed pubescence on promesonotum. PETIOLE. With one pair of long, backward directed hairs. POSTPETIOLE. With two pairs; first gastral tergite bare except for few sparse appressed pubescence, the remaining gastral tergites with some long hairs. SCULPTURE. Cephalic surface smooth and shining except posterior margin of head, area in front of eyes and mandibles longitudinally rugulose; promesonotal dorsum faintly irregularly sculptured; mesopleura, propodeum, petiole and postpetiole densely punctulate-reticulate; gaster smooth and shining. COLOUR. Uniform yellow, eyes black, mandibular teeth dark brown. Differential diagnosis Among the Arabian Trichomyrmex species, T. shakeri sp. nov. is a conspicuous species, quickly identified by the uniform yellow colour and the exceptionally larger eyes (EL 0.31–0.36 × HW) compared to other sympatric species. Trichomyrmex shakeri sp. nov. is superficially similar to T. santschii (Forel, 1907) from North Africa (Tunisia) in colour and measurements, but it can be readily separated by the absence of the psammophore, which is well-developed in T. santschii. Ecological and biological notes This species is considered uncommon. Only six workers were collected in 150 pitfall traps run for one year at the type locality, a relatively pristine section of Wadi Hanifa (Fig. 13 D). Other sampling methods (soil sifting, light traps, beating sheets) were not successful in adding more material.Published as part of Mostafa R. Sharaf, Shehzad Salman, Hathal M. Al Dhafer, Shahid A.

Diagnosis. Tetramorium saudicum is a member of the caespitum -group. It can be readily separated from its closest congener, the Palaearctic T. striativentre Mayr, 1877 from Kazakhstan by the bicoloured body, head, mesosoma, waist and appendages reddish brown, gaster brownish or blackish brown; whereas T. striativentre is unicolorous brownish and the appendages are pale brown. Both species are similar in body size, mesosomal and gastral sculpture, and the frontal carina that extend back to the posterior margins of eyes. Tetramorium saudicum also differs from T. striativentre by the following: the head dorsum is polished with few (nearly 10) fine longitudinal rugulae superimposed upon irregularly punctulate ground-sculpture while in T. striativentre, the head dorsum is dull with numerous (nearly 20) very fine longitudinal rugulae superimposed upon a finely and densely punctulate or granular ground-sculpture. In addition, the petiolar node of T. saudicum in dorsal view is clearly irregularly rugulose, whereas in T. striativentre the petiolar node in dorsal view is clearly regularly longitudinally rugulose. Tetramorium saudicum can be distinguished from the remaining Arabian species of the genus (except T. sericeiventre and T. khyarum) by the sculptured first gastral tergite. It can be separated from T. sericeiventre and T. khyarum by the following characters: the scape index is much smaller, SI 63–71 (versus SI 113–118 for khyarum and SI 101–118 for sericeiventre); the head length is smaller, HL 0.75–0.85 (Versus HL 0.96–1.00 for khyarum and HL 0.80–1.00 for sericeiventre) and eyes relatively larger, EL 0.20–0.25 (versus EL 0.20 for khyarum and EL 0.16–0.22 for sericeiventre). Description of worker. Head: Head as long as wide or subequal, with convex sides and nearly straight posterior margin; anterior clypeal margin entire; ventral surface of head with few ammochaete setae; frontal carinae present, running back beyond level of posterior margin of eyes but feebly developed throughout their length and weaker behind eyes than in front; eyes large (EL about 0.29 x HW) with about 15 ommatidia in longest row; ventral margin of eyes more or less flat, anterior, dorsal and posterior margins curved so that eyes in profile resembling reclinate letter D; mandibles longitudinally rugose; antennae 12-segmented; antennal scrobes absent; entire dorsum and profile of head very finely and very densely longitudinally costulate, spaces between costulae finely, irregularly and densely punctulate; dorsum of head with many paired hairs. Mesosoma: Outline of dorsal mesosoma unbroken in profile; pronotal humeri sharply angulate; metanotal groove not impressed; propodeal spines acute and strongly developed; dorsal (outer) surface of hind tibiae with appressed pubescence; propodeal dorsum with a single pair of short hairs; mesosoma strongly longitudinally rugulose, space between regulae smooth and shining. Waist: Petiole cuboid; petiolar and postpetiolar nodes in dorsal view distinctly broader than long; petiole with one pair of hairs, postpetiole with three pairs of hairs; petiolar node in dorsal view clearly irregularly rugulose; postpetiolar node distinctly strongly longitudinally rugulose. Gaster: First gastral tergite longitudinally, very finely and very densely striated, appearing dull; gaster with scarce scattered erect hairs and moderately dense appressed pubescence. Bicoloured species, head, mesosoma, petiole, postpetiole and appendages reddish brown, gaster brownish or blackish brown. Etymology. The name of this species, saudicum, refers to the type locality, the Kingdom of Saudi Arabia. Habitat. Tetramorium saudicum was observed nesting directly in the ground and many workers were observed carrying dry plant seeds.Published as part of Sharaf, Mostafa R., Abdel-Dayem, Mahmoud S., Al Dhafer, Hathal M. & Aldawood, Abdulrahman S., 2013, The ants (Hymenoptera: formicidae) of Rawdhat Khorim Nature Preserve, Saudi Arabia, with description of a new species of the genus Tetramorium Mayr, pp. 565-580 in Zootaxa 3709 (6) on pages 574-576, DOI: 10.11646/zootaxa.3709.6.6, http://zenodo.org/record/630001

Review of the ant genus Technomyrmex Mayr, 1872 in the Arabian Peninsula (Hymenoptera, Formicidae)
No full textThe taxonomy of the dolichoderine ants of the genus Technomyrmex Mayr, 1872 is revised for the Arabian Peninsula. Six species are treated, T. albipes (F. Smith, 1861), T. difficilis Forel, 1892, T. briani Sharaf, 2009, T. vexatus (Santschi, 1919), T. montaseri Sharaf, Collingwood & Aldawood, 2011, and T. setosus Collingwood, 1985. The successful tramp species T. difficilis Forel, 1892 is recorded for the first time from the Kingdom of Saudi Arabia (KSA) and Yemen, representing new records for the Palearctic Region. Technomyrmex vexatus (Santschi, 1919) is a new species record for Yemen. The queen caste of the rare endemic species, T. briani Sharaf, 2009 is described for the first time. A neotype for KSA endemic T. setosus Collingwood 1985 is designated based on a specimen collected from the type locality, the Asir Mountains, KSA, including new information on habitats and distribution. A male cast of Technomyrmex, possibly of T. setosus, is also described. An illustrated key based on the worker caste of the Arabian species of Technomyrmex is given. New geographical records and a distribution map for the treated species are presented
