Psinidia Genus Group D. Otte, 1984
Psinidiini D. Otte, 1995
Likely closely akin to the Hippiscini, but more slender, mostly smaller, and with a distinctly different shape to the head and pronotum. The head is usually large with the top higher than the top of the pronotum, and with the eyes large and giving a "bug-eyed" look. The pronotum is usually strongly sculptured with short ridges and projections above, and with the median ridge strong in at least the front, and strongly cut twice. The wings are clear, or yellow to red or pink, and most often there is a dark cross band with a spur. One Mexican species (Trachyrhachys funeralis has the wings nearly all black and blue near the base. The color pattern of the body and tegmina may be much like in the Hippiscini, but more often the tegmina have two or three dark cross bands that are strongest near the lower margin (when folded). The pronotum in most species has a projection or squared lower rear angle on the lower sides, and it is often flared out sideways in this same area. Like in the Hippiscini, no species are known to crepitate in flight. Also, like that group, the male epiphalus of most species trilobed near the ends.
