Agroecotettix silverheelsi sp. nov.Figs 2 B, 4 A, 5 A, 7 A – J, 25, 23 A – C, 25, 26 ADiagnosis.Differentiated from the other species in the group based on the male cerci that have the ventral branch longer than the dorsal branch and by the male aedeagus that has a thickened sheath, and the valves of that are shorter than the sheath with broadly rounded apices (Figs 4 A, 5 A). Most similar to A. aristus and A. texmex but differs from those by the shape of the male genitalia which in caudal view, has the valves of the aedeagus relatively shorter and broader than in A. aristus (Figs 4 B, 5 B) and by the having valves that that are parallel (Figs 4 A, 5 A) as opposed to diverging apically as in A. texmex. (Figs 4 D, 5 D); in lateral view, the distal edge of the valves is broadly rounded.Male measurements (mm).(n = 7) Body length 20.6–24.5 (mean = 22.7); pronotum length 4.4–5.5 (mean = 5.2); tegmen length 2.9–4.0 (mean = 3.4); hind femur length 10.4–12.4 (mean = 11.6); cerci length 1.4–1.7 (mean = 1.6); basal width of cercus 0.5–0.6 (mean = 0.6); mid-cercal width 0.4 (mean = 0.4); cerci dorsal fork length 0.4–0.5 (mean = 0.5); cerci dorsal fork apex width 0.2 (mean = 0.2); cerci ventral fork length 0.6–0.8 (mean = 0.6); cerci ventral fork apex width 0.1 (mean = 0.1).Phallus measurements (mm).(n = 3) Length 0.7–0.8 (mean = 0.8); apex width 0.4–0.5 (mean = 0.4); middle width 0.5–0.8 (mean = 0.7); basal width 0.6–0.7 (mean = 0.6); lateral apex width 0.2–0.4 (mean = 0.3); lateral medial width 0.3–0.4 (mean = 0.3); lateral basal width 05–0.7 (mean = 0.6).Female measurements (mm).(n = 3) Body length 25.2–27.2 (mean = 26.2); pronotum length 6.5–7.2 (mean = 6.8) tegmen length 4.5–5.1 (mean = 4.8); hind femur length 13.2–15.2 (mean = 14.2); dorsal ovipositor valve length 1.2–2.1 (mean = 1.8); ventral ovipositor valve length 1.2–2.1 (mean = 1.8).Holotype.• 1 ♂, USA, Texas, Dimmit Co., Asherton, 28.4559, -99.7778, 19 July 2020, J.

Deposited in the Mississippi Entomological Museum.Specimens examined.USA, Texas: • Dimmit Co., Asherton, 28.4559, -99.7778, 19 July 2020, J. G. Hill (1 ♂, 1 ♀). • Maverick Co., 1.8 mi E Eagle Pass, 18 August 1961, I. J. Cantrall and T. J. Cohn (5 ♂, 2 ♀).Habitat.On Vachellia branches in an open grassland with Opuntia, Cylindropuntia, and Prosopis (Fig. 26 C).Distribution.Known only from the northwestern South Texas Plains region of Texas (Fig. 25).Etymology.The name silverheelsi is a patronym honoring Jay Silverheels. a Native American athlete and actor who most famously portrayed the fictional character Tonto in “ The Lone Ranger ” television series from 1949–1957. Silverheels was one of the first Native American actors to portray a major Indigenous character on a television series. Throughout his career, Silverheels advocated for more inclusion of Indigenous people in media and founded the Indian Actors Workshop in Los Angeles during the 1960 ’ s. This naming honors Silverheels’ cultural impact and the Texas landscapes where the series was set.Suggested common name.Silverheels’ aridland scrub jumper.

Haplothrips talpa PriesnerHaplothrips (Trybomiella) talpa Priesner, 1931: 243The species was described from South Africa from grasses, reported from Egypt, India, Libya, Sudan (Wafy 2023), and in Arabian Peninsula is known from Saudi Arabia (zur Strassen 1979). However, it was not recovered during current study. Among the members of subgenus Trybomiella, H. talpa is distinct by having a single sense cone on antennal segment III and smooth distal fore wing cilia (Priesner 1950).

Genus Monilea Swainson, 1840Monilea Swainson, 1840: 220, 350.Type speciesTrochus calliferus Lamarck, 1822 (monotypy), Recent, Indo-West Pacific.RemarksThe taxonomy of the genus Monilea is complex and in need of revision – much remains unresolved. If illustrated at all, the original figures of the species described in the 19 th century were frequently poor. As a consequence, use of these names in more recent literature has lacked authority and many have been used inconsistenly. Rarely was there evidence that the type material had been consulted and more recent authors have simply followed earlier authors in applying names. This situation is further exacerbated by the fact that recent illustrations often present the shell in apertural view only, which does not show critical features of umbilical morphology. Some of the species currently referred to Monilea (MolluscaBase 2024) belong instead to Talopena, which I consider to be a distinct genus. This issue is discussed further under the Remarks for Talopena (below) where I provide illustrations of the holotypes of the type species of both genera (Fig. 34) and detail the characters which set them apart. None of the New Caledonian material examined is referable to Monilea.

L’adaptation des établissements publics aux nouvelles exigences de la bonne gouvernance, d’innovation, de qualité et de la performance, dans le contexte actuel de la mondialisation, dépend de la place qui y est accordée au système d’information notamment comptable. Le domaine des innovations en Système d’Information est large et peut concerner en même temps le côté technique et administratif d’une organisation. Ainsi une innovation en système d’information peut être l’adoption d’une nouvelle technologie (matériel ou logiciel) ou d’une nouvelle forme ou méthode d’organisation du travail (Swanson, 1994). Plusieurs constats ont mis en évidence la trop lente diffusion des outils modernes de gestion notamment la gestion comptable dans les organisations publiques malgré leurs avantages par rapport aux outils traditionnels. Dans ce travail de recherche, nous avons tenté d’apporter de nouveaux éléments de réponse à ce paradoxe, en examinant deux volets de l’introduction d’une comptabilité d’exercice (CE) au sein des centres hospitaliers universitaires au Maroc. Il s’agit du choix d’adoption et du succès global de la mise en œuvre d’une CE. S’appuyant sur un cadre de référence riche et varié, notamment les approches et les travaux sur la diffusion des innovations en système d’information et sur le nouveau management public, nous avons construit deux modèles théoriques : le premier sur le choix d’adoption d’une CE qui examine les facteurs explicatifs de la décision d’adoption de ce système comptable. Le deuxième concerne les déterminants du succès global de la mise en œuvre d’une CE. A travers une enquête sur les pratiques actuelles des centres hospitaliers universitaires en matière de leur système comptable, nous avons testé empiriquement nos deux modèles de recherche. Les résultats de l’analyse des données de notre enquête nous ont permet de constater l’influence de deux facteurs essentiels dans les choix d’adoption d’un CE, il s’agit de : «Réorganisation comptable» et «Objectifs du système de la CE». Pour les facteurs de succès testés, trois facteurs jouent un rôle significatif. Il s’agit de : «Soutien de la direction générale », «Formation» et «Capacité à surmonter la complexité perçue du système de la CE».
