Subtribe Bambusanina subtribe nov. urn:lsid:zoobank.org:act: C5644A9F-720E-45DA-A216-951416D7A496 Fig. 5 Type genus Bambusana Anufriev, 1969. Description Small to medium-sized cylindrical or wedge-shaped deltocephalines, color stramineous to brown, with extensive dark brown markings dorsally (rarely green without dark markings), forewing veins usually pale, bordered with brown, head with crown anterior margin broadly rounded to angulately produced, rounded to face, and without transverse carinae, crown between eyes less than 1.5× eye width, face in anterior view wider than tall and orientation oblique in profile, anteclypeus narrow basally and expanded distally, forewing macropterous and often with supernumerary crossveins and without reflexed costal veins basad of Rs origin, profemur with AM1 near midheight of anterior surface, male abdomen with 2s apodemes enlarged or not and if so usually parallel, not elongate and not divergent or capitate, male pygofer with profuse macrosetae and with one or more sclerotized ventral processes arising preapically and often extended mesad but not articulated with aedeagal atrium, subgenital plate much shorter than pygofer and lateral margins convex and usually with macrosetae scattered or in irregular sublateral rows, connective articulated to aedeagus and with anterior branches parallel or slightly divergent, style with apex usually enlarged and often modified with teeth or branches, membrane laterad of aedeagal atrium with basal or distal branches, ovipositor protruding well beyond pygofer apex, first valvulae dorsal sculpture granulose, areolate, or imbricate, reaching dorsal margin of valvula or with dorsal unsculptured dorsal band, second valvulae with distal teeth short and widely spaced, sometimes absent. Remarks This subtribe is here established to include a group of bamboo-associated Oriental genera formerly placed in Athysanini or Opsiini that is sister to Vartina + Punctulina in the phylogenomic results of Cao et al. (2022). The dataset of Cao et al. (2022) included six genera that are here placed in the new tribe: Abrus, Alishania, Bambusana, Bambusananus, Branchana and Neurotettix). Although these genera lack the more distinctive characteristics of the latter two subtribes, they are similar in having the male pygofer, style and aedeagus often highly modified and in lacking elongate, capitate 2s apodemes. Distribution Oriental. Included genera Abrus Dai & Zhang, 2002; Alishania Vilbaste, 1969; Bambusana Anufriev, 1969; Bambusananus Li & Xing, 2024; Branchana Li, 2024; Fuscmacula Yao, Zhang & Xing 2021; Neurotettix Matsumura, 1914.
