( Figs 5–8 , 27–28 , 39 , 57 , 64 , 80 , 88, 91, 94, 98, 102 ) Measurements. Males 4.90–5.45 mm long, 1.40–1.45 mm wide across eyes; females 5.35–5.95 mm long, 1.50–1.53 mm wide across eyes. Head and thorax (color). Ground color ochraceous with brown and dark brown markings. Crown ( Fig. 6 ) with pair of elliptical dark brown spots contiguous to pronotal ones, and equally distant between eyes and median line, and with median brown thin stripe. Face ( Fig. 27 ) with conspicuous, inverted dark brown Y-shaped macula; area adjacent to ocelli with pair of large dark brown maculae connected to Y-shaped macula, all three gradually fading to brown. Frontoclypeus ( Fig. 27 ) with several irregular dark brown maculae forming pair of lateral rows surrounded by brown maculae; clypellus brown with upper, median, and lower markings, dark brown; genae with dark brown maculae on antennal ledges and lateral sutures; lora with dark brown maculae at inner and outer margins. Pronotum ( Figs 5–6 ) with five marks as follows: one dark brown pair, elongate, adjacent to anterior margin except in middle; median stripe in between two large, rather triangular maculae, in median region, pale brown to brown. Mesoscutum ( Fig. 6 ) brown with pair of laterobasal triangular maculae and pair of small rounded marks at central portion, dark brown; mesoscutellum with pair of large lateral basal portions and median dark brown maculae. Forewings ( Figs 5–6 ) brown with claval veins, and wing margins ochraceous, most of costal area and adjacent cells hyaline. Legs ( Fig. 5 ) ochraceous. Morphology. As in generic description. Male genitalia. Pygofer ( Fig. 39 ), in lateral view, with posterior margin semi truncate, bearing scattered small setae. Subgenital plates ( Fig. 39 ), in lateral view, with surface bearing many small setae, dorsoapical surface with long scattered setae. Styles ( Figs 57 , 80 ), in lateral view, with inner fork longer than outer fork. Connective ( Fig. 80 ), much broader along posterior margin compared to anterior margin, and not fused to aedeagal base. Aedeagus ( Fig. 57 ), in lateral view, V-shaped, lacking processes, basal region broad and stout, dorsal apodeme subequal to aedeagal shaft length; shaft in lateral view tapered apically; in caudal view ( Fig. 64 ), of uniform width but broadened slightly near gonopore; apical margin slightly concave; gonopore subapical. Abdominal segment X ( Fig. 39 ) without process. Female (color). Female paler than male. Other features similar to male. Female genitalia. Sternite VII ( Fig. 88 ) with hind margin triangular. Second pair of valvulae ( Fig. 98, 102 ) with conspicuous dorsal prominence; teeth basally subtriangular, becoming subrectangular and increasing in size and distance between them towards apex, not bearing denticles.

Kavanaugh, R.L. Brett, E.Elsom and F. Vargas collector” (CAS, INHS). Etymology. The species is named in honour of Mr M.D. Webb (BMNH) for his excellent contributions to Auchenorrhyncha systematics. Remarks . Among the species of Agallidwipa , this is the only species that lacks any process on the abdominal segment X. It resembles A. pauliana in the structure of aedeagus but differs in having a shallow excavation on the apical shaft.
