Agroecotettix chiantiensis sp. nov. Figs 2 N, 4 J, 5 J, 16 A – J, 25, 26 A, 33 A – C Diagnosis. Differentiated from other species in the genus by the combination of male cerci with ventral branch equal or subequal in length to dorsal branch (Figs 2 N, 15 A, B); sheath of aedeagus thin and lightly sclerotized (Fig. 5 J); valves of the aedeagus are lobate, and in lateral view, are deeply incised with a narrower and slightly acute distal lobe and a longer basal lobe as in Figs 5 J, 16 D, F); in caudal view the valves of the aedeagus are convex as in Figs 4 J, 15 G). Male measurements (mm). (n = 1) Body length 20.5; pronotum length 4.2; tegmen length 3.2; hind femur length 11.2; cerci length 1.1; basal width of cercus 0.5; mid-cercal width 0.4; cerci dorsal fork length 0.3; cerci dorsal fork apex width 0.2; cerci ventral fork length 0.2; cerci ventral fork apex width 1. Phallus measurements (mm). (n = 1) Length 1; apex width 0.4; middle width 0.4; basal width 0.6; lateral apex width 0.5; lateral medial width 0.7; lateral basal width 0.7. Female measurements (mm). (n = 1) Body length 25.1; pronotum length 6.2; tegmen length 3.7; hind femur length 15.1; dorsal ovipositor valve length 2; ventral ovipositor valve length 2. Holotype. • 1 ♂, USA, Texas, Presidio Co., 32 mi SW Marfa, 30.0488, -104.4663, 15 July 2023, J. G. Hill, thorny shrub in Chihuahuan Desert, Chianti Mountains. Deposited in the Mississippi Entomological Museum. Specimens examined. USA, Texas: • Presidio Co.; Chianti Mountains, 30 September 1928, E. R. Tinkham, (1 ♀) • 2.3 mi S Shafter, 23 July 1956, T. J. Cohn, B. Mathews (1 ♂) • Shafter cemetery, 29.8112, -104.3058, 28 September 2024, J. G. Hill, J. L. Seltzer (1 ♀). Habitat. Chihuahuan Desert Scrub (Fig. 33 C) on leguminous shrubs and Yucca. Cohn (1956) describes the habitat at 2.3 mi S Shafter as “ rocky foothills of the Chiantis on Spanish bayonet [Yucca sp.] ”. Distribution. Known only from the Chianti Mountains of southwest Texas (Figs 25, 26 A). Etymology. The species name chiantiensis is derived from the Chianti Mountains where the species is apparently endemic to and the suffix “ - ensis ” (Latin) meaning “ originating from ” or “ inhabiting ”. This name reflects the endemic nature of the species and hopefully draws attention to the importance of conservation of the unique biodiversity in this understudied mountainous region. Suggested common name. Chianti aridland scrub jumper.
