A New Species

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.

Comprehensive Survey

A comprehensive survey was conducted at different provinces of Saudi Arabia (SA) to investigate predacious prostigmatid mites (Acari: Trombidiformes: Prostigmata) mainly collected from the date palm, Phoenix dactylifera L. (Arecaceae) agro-ecosystem. A total of 41 species belonging to 28 genera in 14 families are recorded in the present study. Out of these, three families, 18 genera and 36 species are new to the mite fauna of SA. The new species, Neobonzia tabukensis sp.nov. (Cunaxidae), Cheletomimus (Philippicheyla) taifensis sp.nov. (Cheyletidae) are described and illustrated. A checklist of predatory prostigmatid mites from SA is given. A key to all terrestrial predatory prostigmatid mites, excluding Parasitegona and Heterostigmatina, reported from SA is provided. Also, a key to world species of the subgenus Philippicheyla Corpuz-Raros of the genus Cheletomimus Oudemans is given.

Collection Data

This paper reports on 35 species and 33 genera belonging to 18 families of the order Mesostigmata, collected from different provinces of Saudi Arabia. Among these, eight families, 21 genera and 30 species, mostly collected from date palm agroecosystem, are new to the fauna of Saudi Arabia. Five species reported previously are also recorded in this study. The collection data and distribution of all species recorded in this study as well as those reported previously are given. A comprehensive key to the females of the mesostigmatic mites reported from Saudi Arabia, except the Phytoseioidea, is provided.

Study Results

Youth is one of the most substantial pillars of community development. The study investigates the optimal structure of youth councils in Saudi Arabia. And it establishes the necessary regulations by setting targets, tasks, conditions of membership, and developing a unified proposal for these councils. The primary study tool was a questionnaire developed by researchers were used to assess the studied parameters. They were distributed to (413) young men at King Saud University in Riyadh, Saudi Arabia, aged (18-34) years. According to the analytical approach, it is a forecast study. The study results showed that the optimal structure of these councils' includes: First, the prince of the region or the governor as a president. Second, the rector as a vice-president. Finally, the commission is equally male and female. While the council objectives: First, take advantage of youth proposals, capacities, and intellectual property. Secondly, youth participation in the discussion, determination of their requirements, and decision-making. Also, it identified a set of tasks: Encouraging creative and talented youth to achieve national accomplishment and motivating them to take on their responsibilities in serving their community. As for the terms of the Council's membership, members must be between 18 and 30 years, and the name of the office shall be two years and nominated by government educational bodies.There should be a responsible body for structuring youth councils regions, increasing youth councils, and meetings between them in a periodic manner among different countries to exchange experiences and improve performance.   Received: 27 October 2020 / Accepted: 10 December 2020 / Published: 17 January 2021
