Diagnosis. This genus differs from all other known genera of Evacanthini in having a median lamellate carina extending from base to apex of the crown; and male pygofer with ventral process.
Description
Male: Medium-sized leafhoppers, bright yellow colored. In dorsal view, head produced conically in front of eyes ( Figs. 1A View FIGURE 1 ), longer and narrower than pronotum. Crown convex with median and subocular carinae converging anteriorly to a point, irregular pale-yellow spot anterad of compound eye on either side of median carina. Face longer than broad, frontoclypeus with prominent median carina and lateral marginal ridges ( Figs. 1D View FIGURE 1 ). Clypellus broad at base and narrowed apically surpassing curvature of gena. Lora long and narrow not extended to lower margin of gena. Pronotum ( Figs. 1C View FIGURE 1 ) convex, rugose-punctate, and broader than head and twice as wide as long. Forewing venation with 2 anteapical cells ( Figs. 3G View FIGURE 3 ). Forefemur AD and PD rows with fine microsetae, AV row with 4 macrosetae followed by thinner microsetae with AV1 well developed, AM1 well developed, row IC with 13 long setae in curved row ( Figs. 3A–B View FIGURE 3 ). Mesothoracic femur row AV with several, short and stout setae ( Figs. 3C View FIGURE 3 ). Hind femur distal macrosetae 2+1+1 ( Figs. 3D View FIGURE 3 ). Hind tibia macrosetae AD 12–13, PD 20–22, AV with numerous long setae ( Figs.3E View FIGURE 3 ). Metabasitarsus with four stout macrosetae associated with basal sclerotized spines, replacing platellae, tarsomere II less than ½ length of tarsomere I ( Figs. 3F View FIGURE 3 ).
Male genitalia: Male pygofer with ventral process ( Figs. 1J View FIGURE 1 ). Subgenital plate as long as pygofer in lateral view, more or less of uniform width, with single longitudinal row of macrosetae extending from near base to apex inner submarginally, several long fine setae on outer lateral margin. Style slender, long, apex of apophysis foot-shaped. Connective Y-shaped with stem longer than arms. Aedeagus without dorsal apodeme, preatrium well developed with irregular and unequal process, aedeagal shaft narrow, long with apical gonopore. with dorsal finger-like process narrowed distally, aedeagal shaft with thin pair of pre-apical and apical processes.
Female: Body coloration slightly lighter and size larger compared to male ( Figs. 2A–D View FIGURE 2 )
Female genitalia: Female Sternite VII broader than long, posterior margin almost straight, medially very slightly elevated and anterior margin slightly convexly rounded with inner membranous area, a remnant of sternite 8, unsclerotized and folded on top of 7 th sternite. ( Figs. 2F View FIGURE 2 ). In lateral view, first valvulae curved dorsally with sculptured area confined to posterior 0.25, sculpturing strigate and extended to dorsal margin, ventral sculptured area restricted to apex, formed by scale like processes ( Figs. 2G–H View FIGURE 2 ). Second valvulae curved ventrally at middle, with small notch near middle of dorsal margin, with denticular area confined to posterior region ( Figs. 2I–J View FIGURE 2 ).
Etymology: The specific epithet refers to the name of the type locality “ Lapnan” from where the specimen was collected.
Distribution: Lapnan and Thinsa, Arunachal Pradesh, India
