 Type-species Tichocoelidia clarkei Kramer, 1962, by original designation.   
 Diagnosis. Pale yellow leafhoppers (Figs 21–28), with or without orange stripes on crown; frons (Figs 1, 11) with small round black spot at the apex of head; transition crown-face (Figs 22, 24, 26, 28) with carina; ocelli (Figs 1, 11) at the transition between the crown and frons; clypeus (Figs 1, 11) with parallel lateral margins or slightly converging apically; pronotum (Figs 21, 23, 25, 27) with posterior margin usually with “V” shaped emargination; forewing (Figs 2, 12) with venation indistinct to weakly visible, except apically, with four apical cells and three anteapical cells; hind wing with veins R 4+5 and M 1+2 converging preapically, fused at the apex; male pygofer (Figs 3, 13) with macrosetae on apical third, dorsal margin with pair of long inner processes, ventral margin with well-developed tooth; subgenital plates (Figs 5, 15) shorter than the pygofer, fused together in basal portion; connective (Figs 6, 16) V-shaped; aedeagus (Figs 8–9, 18–19) long and narrow, dorsal apodeme membranous; anal tube (Figs 10, 20) with pair of processes.   
 Description. Leafhoppers (Figs 21–28) yellow to pale yellow, green in life; crown with or without orange stripes; frons (Figs 1, 11) with small round black spot on the apex of the head. Head, in dorsal view, (Figs 21, 23, 25, 27), narrower than pronotum; crown subquadrangular or subpentagonal, moderately produced anteriorly, approximately as long as wide; anterior margin arched or angled; surface smooth, flat or slightly concave; coronal macules indistinct or weakly distinct; coronal suture indistinct. Head, in lateral view (Figs 22, 24, 26, 28), crownface transition with thin carina; lateral margins, adjacent to eyes, elevated and slightly carinate; ocelli small, on the anterior margin of head, at crown-face transition, closer to eyes than to midline; antennal ledges vertical and carinate; antennal flagellum as long as body, exceeding the basal half of forewing; frons convex. Head, in frontal view (Figs 1, 11), with frons about twice as long as wide; frontogenal sutures reaching ocelli; apex of maxillary plates approximately same height as apex of clypeus or slightly above it; lorum approximately half-moon shaped, inferior margin not reaching apical margin of clypeus; epistomal suture complete; clypeus with parallel lateral margins or slightly converging apically.   
 Pronotum (Figs 21, 23, 25, 27) with V-emarginated posterior margin; surface with transverse striae; dorsopleural carina complete, long and evident. Forewing (Figs 2, 12) semi-hyaline; venation mostly indistinct, except for veins delimiting apical cells; three anteapical cells visible only apically; four apical cells, all approximately rectangular, third apical cell distal to the base of the wing compared to the second and fourth apical cells; alar appendix narrow, extending only along first apical cell. Hind wing with three apical cells, R 4 +5 and M 1+2 convergent preapically, fused at apex, forming single vein. Profemur with AD, AM and PD rows reduced and poorly defined, except for apical setae AD 1, AM 1 and PD 1; AV row formed by two preapical setae; IC row formed by slightly arched comb of 8–9 fine setae, beginning at distal half of femur and extending to near apex. Metafemur with setal formula 2:2:0. Metatibia with AD row with two or three intercalary microsetae between macrosetae. Metatarsomere I with two parallel rows of small setae on plantar surface; apex with seven platellae. Metatarsomere II apex with three platellae.   
 Male terminalia. Pygofer (Figs 3, 13) slightly narrowing towards at apex; macrosetae present; dorsal margin with pair of long inner processes, near base of anal tube and extending posteriorly; ventral margin with basal or median large tooth curved ventrally; apex rounded. Subgenital plates (Figs 4–5, 14–15) shorter than pygofer; completely fused to the valve and fused to each other basally, free only in apical portion; macrosetae absent; apices rounded. Connective (Figs 6, 16) V-shaped. Style (Figs 6–7, 16–17) moderately long; preapical lobe reduced; dorsal margin smooth; apex slightly curved ventrally, with setae on apical third. Aedeagus (Figs 8–9, 18–19) long and narrow; dorsal apodeme membranous. Anal tube (Figs 10, 20) with pair of processes.   
 Female terminalia. Female unknown.
