Rasool” / “Paratype Afrotarus soudaensis sp. n.; det. I. Rasool, R.F.F.L. Felix, & M.S. Abdel-Dayem, 2015” [yellow label] [RMNH]. Specific epithet. The specific epithet is a Latinized adjective form based on Al Souda area from which the holotype of this new species was collected. Recognition. This species can be distinguished from other members of the genus by the combination of fusco– brunneous body, finely and sparsely punctate; pronotum slightly wider than long, lateral margins with one pair of setae before anterior angles, hind angles not protruded; intervals of elytra finely pubescent laterally; aedeagus hooked apically, smoothly curved to apex. Description. Habitus. body elongate subovoid (Fig. 22), TBL male 6.8–8.0 mm, female 8.0–9.0 mm. Colour. great variation in colour, from testaceous to fusco-brunneous; border of frons and clypeus dark, elytra with testaceous humeral macula and sometimes testaceous macula at apex near suture, in some specimens humeral macula starts from intervals IV up to lateral margin and extend posteriorly to one fourth of elytra, in others humeral macula extends from suture to lateral margin, in some individuals one testaceous macula on apex of elytra not reaching suture or apical margin. Microsculpture. head, elytra and ventrum smooth; labrum with mesh pattern isodiametric; short transverse microlines effaced on disc of pronotum along median longitudinal impression. Luster. Body shiny. Head. slightly elongate (Fig. 10), HL 1.55–2 mm and HW 1.25–1.62 mm, as long as width of pronotum; finely and sparsely punctuated; eyes small and slightly prominent; temples long with irregular pubescence; neck constricted; two pairs of supraorbital setae present, two ridges near eyes covering the clypo-ocular surface; clypeus and labrum transverse, clypeus with few fine hardly visible punctures on the surface and one pair of lateral setae; anterior margin of labrum slightly concave, with series of five setae; median tooth of mentum broad and pointed at apex; antennae surpassing pronotal base by 3 antennomeres, antennomere II shorter than others, III longer than the rest, I, IV and XI equal, V–X subequal and shorter than I, IV and XI, pubescence starts from antennomere III. Pronotum. slightly wider than long (Fig. 10), PW 1.42–1.95 mm, PL 1.25–1.75 mm; surface finely punctate, along with micropuncture; lateral margins of pronotum constricted posteriorly but not sinuate; median longitudinal impression clear and not deep; anterior margin concave with rounded angles; one pair of setae at anterior half of lateral margins before anterior angles; base of pronotum almost straight, medially raised; hind angles slightly obtuse, not protruded. Elytra. elongate subovoid. EL 3.7–5.3 mm and EW 2.5–3.7 mm; widest behind mid-length, rounded at humeri and apical edges, obliquely truncate at apex; striae deep and clear, intervals with dense but fine punctuation. Legs. mesotibia with row of sharp spines on its outer surface starting just before middle; tarsomere I in fore leg shorter than tarsomere V, equal in mid leg, longer in hind leg; tarsomeres I–III in fore leg of male dilated; claws with 3 teeth in the middle. Abdomen. five visible abdominal ventrites, very finely punctate, laterally pubescent; apical margin of last ventrite almost rounded in both sexes; surface of last abdominal segment densely punctate and pubescent; 4 setiferous punctures at apical margin of ventrites, two medially and two laterally. Aedeagus. shape of aedeagus (Fig. 16), in lateral view male genitalia gently curved; apically hooked; apical portion more narrow than base and smoothly narrowed. Genitalia widened at the middle. Affinity. This species is closely related to the previous species Afrotarus fadli sp. n. and A. scotti (Basilewsky, 1948). From the former species it can be distinguished by darker colour; pronotum slightly wider than long; mentum with median tooth pointed; elytra laterally with short pubescence; aedeagus not abruptly narrowed apically. However, it differentiates from A. scotti (Basilewsky, 1948) by hind angles of pronotum not protruded and without setae; aedeagus hooked. Geographical distribution. This species is known only from W. Gouz and Rayda Nature Reserve in Asir mountains, southwest of Saudi Arabia (Fig. 29). Ecological note. Apterous species that was collected from 2363–2820 m. These beetles inhabit the Juniper forest in Rayda Nature Reserve. All the specimens were collected by hand under stones on substrate covered with fallen leaves and vegetation debris. In Rayda Nature Reserve, most of the specimens were collected near waterfall from moist and humid places (Fig. 26, 27).Published as part of Rasool, Iftekhar, Felix, Ron F. F.

Furthermore, in <i>L. zanzibarica</i> the frons and disc of the pronotum are much more coarsely punctured, while in <i>L.</i> spec. the frons is smooth and only sporadic punctured. Also the sculpture of the pronotum is different.</p> <p>The fact that the collected specimens do not correspond with nearby Afro-Ethiopian species, studied in the collection of the Tropical Africa Museum, Tervuren, Belgium, suggests that these specimens belong to a new species.

[yellow label] Type locality. Shada Al Aala Nature Reserve (N19°50.575' E41°18.691'), 20 km northwest the city of Al Makhwa, Al Baha Province, southwest of Saudi Arabia. Etymology. The specific epithet is a Latinized noun in the genitive case in the feminine form based on honorific mother’s name “Raeesa” of Iftekhar Rasool. Recognition. Adults of Lebia raeesae sp. n. can be distinguished from other members of Lebia from Arabian Peninsula by the following combination of external features: large body size, mentum with suture dividing the lateral lobes and epilobes, crenulated inner apical mesotibiae in male, smooth apical margin or elytra, longer antennae which surpass pronotal base by four and half antennomeres and reaching first quarter of the elytra, last abdominal sternum feebly notched medially and bi-setose in females, tarsomere IV incised and by shape of aedeagus. Description. Habitus. Body form (Figs. 21, 22), TBL Holotype 9.1 mm, TBL Paratypes 8.4–9.3 mm. Colour.

Luster. Head, pronotum, elytra and ventrum including abdomen glossy. Head. Slightly wider than long (Fig. 33), HL 1.50 mm and HW 1.60 mm, narrower than pronotum; dorsum with deep and moderately coarse punctures on frons and vertex; frons depressed between eyes and provided with irregular wrinkles; eyes prominent; neck strongly constricted with tempora short; clypeus strongly transverse, sparsely and finely punctate; labrum slightly wider than long, rounded anteriorly and laterally; last labial palpi fusiform; mentum with median blunt tooth and with epilobes; antennae surpassing pronotal base by four and half antennomeres and reaching first quarter of the elytra, antennomere II shortest, XI longest, rest of the antennomeres equal in length. Pronotum: Strongly transverse (Fig. 33), PL 1.42 mm, PW 2.14 mm, maximum width just posterior of anterior lateral setae; anterior margin of pronotum slightly concave, anterior angles strongly rounded; lateral margin anteriorly rounded, obliquely straight after anterior lateral setae, not sinuate in front of posterior angles; posterior angles right; base of pronotum strongly incised and lobate at the middle; anterior, lateral and basal margins marginate, lateral margin explanate throughout, marginal channel widened posteriorly; surface of pronotum irregularly wrinkled except lateral margin, median longitudinal impression weak; anterior lateral setae located about at apical third, posterior lateral setae located at basal angle. Elytra: Elongate, widened posteriorly, EL 5.75 mm, EW 3.75 mm, maximum width after middle; humeri rounded, lateral margin obliquely convex, apical margin obliquely truncate; striae complete, deep and coarsely punctate; striae V and VI joint apically; intervals convex throughout; 1 setiferous puncture on interval II near scutellum; 2 setiferous punctures on intervals III, first at anterior fourth and second at posterior edge of transverse band margin of elytra with series of 14-setiferous pores interrupted medially, pores become bigger posteriorly; hind wigs fully developed. Legs: Long and slender, tarsomeres I–III dilated in fore leg of male; inner side of mesotibiae crenulated at apical edge; tarsomere I shorter than V in fore leg, as long as V in mid leg and hind leg; claws pectinate. Abdomen: Sterna with scattered pubescence dense laterally; last sternum feebly notched medially, bi-setose in male, tetra-setose in females. Aedeagus: (Fig. 41), AL 1.60 mm, in lateral view, gently curved, strongly narrowed towards apex, dorsal and ventral margins slightly curved, thickened at the base and middle; apical lamina rounded and long. Affinity. Lebia raeesae sp. n. apparently is similar to L. auberti, from which it can be differentiated by smooth apical margin of elytra, not serrate; labrum as long as clypeus; round anterior margin of labrum; aedeagus dorsal and ventral margins curved, not sinuate near base as in L. auberti. Ecological notes: Members of Lebia raeesae sp. n. live at elevations of 1611–1897 m in Shada Al Aala and Rayda nature preserves in Saudi Arabia, also one specimen was collected from Yemen at 1200 m. Adult beetles were collected by UV-light traps from steep slopes covered by different vegetation that are dominated by Cactus plant Opuntia ficus-indica (L.) Mill. (Cactaceae) (Figs. 45, 46) and wild olive trees Olea europaea. Also, it is collected by Malaise trap. Adults were collected during January, March, April and August. Geographical and Local distribution. This species is known from its type locality, in the Mountains of the southwestern Saudi Arabia, at Shada Al Aala (in Al Baha) and Rayda (in Asir) nature reserves (Fig. 43); and from Yemen at Al Lahima. Comment s. According to data base of Carabidae of the world (Anichtchenko, 2016), Lebia auberti, L. melanacra and L. melanura are placed under the subgenus Nematopeza Chaudoir, 1871. According to Felix (2014), Nematopeza is characterized by single deep incision on inner epical edge of mesotibiae, lateral lobes of mentum are divided by suture forming epilobes and complete basal margin of elytra. But the former three species differ in apical incision on mesotibae that is crenulated in L. auberti, two incisions in L. melanacra and a single incision in L. melanura. The new species L. raeesae shares the character of epilobes divided by suture with these species, but mesotibiae are similar to L. auberti and such character state also present in Pseudopachylebia Mateu, 1971 according to Felix (2014). The incomplete subgeneric classification and characters in the genus Lebia need an extensive examination of all relevant species. Thus L. raeesae sp. n. is not assigned to any subgenus of Lebia and until the data on the subgenera becomes complete, the authors consider this species as “ Incertae Sedis ”.Published as part of Rasool, Iftekhar, Abdel-Dayem, Mahmoud S., Felix, Ron F.

Saudi Arabia, Al Baha, Baljurashi, Al saad Janabeen, beaten from Commiphora sp., 22 September 2020 (19.881683°N, 41.704017°E alt. 1914 m) (I. Rasool) (KSMA). Paratypes: same data as holotype, 21 females, 6 males, 4 larvae; Qilwa, Ramziyah, 19 females, 2 males, 7 larvae from unknown plant, 25 September 2020 (I. Rasool) (KSMA). Comments. This new species is unique among members of Eremiothrips in having such a long mouth cone. It shares with E. shirabudinensis, E. antilope and E. aldryhimi sp. nov. similarly long paired processes on tergite IX of males. However, both sexes of this new species have an exceptionally long mouth cone, reaching to the posterior margin of the pronotum (in contrast to a short mouth cone), and the unicolourous pale yellow body lacks any trace of grey or light brown shading (in contrast to grey shading present on abdomen and pterothorax). Moreover, the male of this new species can be distinguished from the former three by the small and oval pore plates on sternites III–VII. In contrast, males of E. shirabudinensis and E. antilope lack pore plates (Bhatti et al. 2003; Minaei 2012) and in E. aldryhimi sp. nov. the pore plates are strongly narrow and transverse.Published as part of Rasool, Iftekhar, Abdel-Dayem, Mahmoud S., Alattal, Yehya Zaki & Aldhafer, Hathal M., 2021, The Anaphothrips genus-group of Thripidae (Thysanoptera) from Saudi Arabia with two new species of Eremiothrips, pp. 1599-1617 in Journal of Natural History 55 (25 - 26) on pages 1611-1612, DOI: 10.1080/00222933.2021.1939187, http://zenodo.org/record/552987
Rainfall-driven machine learning models for accurate flood inundation mapping in Karachi, Pakistan
No full textUrban pluvial flooding (UPF) has emerged as a serious natural hazard, especially in recent years. Previous research on UPF prediction has mainly focused on hydrological models, which required a large amount of data. However, a data-driven method can significantly reduce the computational cost by using rainfall amounts to predict pluvial flooding. Intensity-duration-frequency (IDF) curves using the Gumbel method can provide a better interpretation of the correlation between rainfall intensity, duration, and probability of occurrence of a given rainfall amount. In this study, machine learning models (ML) for rainfall amounts were used to identify flood points in a case study conducted in Karachi, Pakistan. Thirteen inundation factors were used for the ML models, including a new factor, curve number. Ten ML models were applied first on training and then on validation data, yielding the inundation points. The training and validation process of the model included 384 flood points. Several statistics were used to verify the performance and accuracy of the model. We found that the Light Gradient Boost Machine and Random Forest Classifier models were the most accurate in training and validating the model, while the Decision Tree and K-Nearest Neighbor models were the least accurate in training and validating the model. The study provides valuable information for decision makers to protect communities from flood hazards by incorporating the likely intensity and duration of rainfall events and carefully selecting influencing factors into flood event prediction models

Empowering sustainable workplaces: A perspective on employee well-being in the light of the job demand resource model
No full textAccentuated by unprecedented challenges, burnout has become a prominent concern affecting employee well-being. The job demands resource (JD-R) model suggests that job demands has the capacity to mitigate employee burnout. Nevertheless, there has been limited attention on the integration of the psychological and organisational processes contributing to such effect. This research aims to analyse the integrative role of psychological (i.e., employee self-regulation) and organisational processes (such as the Human Resource Management system) in the JD-R model to enhance well-being in workplaces. Consistent with Sustainable Development Goal (SDG) 3 of the United Nations (‘healthy lives and well-being’), the results of this research conducted in public sector hospitals suggest that job demands affect employee burnout through the mediation of employee coping (self-regulation) strategies. Furthermore, the research enriches the existing literature by showing how employee self-regulation and organisational Human Resource Management practices may alter the effect of job demands on burnout
