A New Genus and Two New Species of Peloridiidae (Homoptera) from New Zealand

Oiophysa ablusa, n.sp. — Fig. 1

Oiophysa ablusa, n.sp.
Fig. 1

General coloration brown, the paranota and costal margins of tegmina lighter, yellowish-brown, the areolae hyaline.

Eyes reddish. Head with an indistinct median carina which extends forward a little on frontal membrane, not deeply notched at middle, broadly rounded and arcuate on each side, at each side in front slightly protruding beyond front margins of eyes.

Pronotum slightly rugulose, truncate in front, roundly excavated behind, with median carina on disc, the sides narrowed anteriorly, the width of front margin three-fifths of hind margin; paranota wide, long, with lateral margins broadly rounded; areolae wide, largely rectangular, about three times as wide as long, some of the areolae at times divided into small cells.

Rostrum long, stout, brown, extending to base of metasternum. Legs brown, moderately long, slender. Scutellum raised, wider than long. Mesoscutum partly exposed.

Tegmina abruptly widened at base, very strongly narrowed posteriorly behind middle, narrowly rounded at apices; lateral margins abruptly expanded at base, there biseriate, uniseriate posteriorly, the widest part with one large, long cell within; cells in rest of tegmina large, the veins strong and raised, the areolae largely sub-opaque.

Length, 3.00mm.; width, 1.70mm. (sub-brachypterous form).

Type (male), allotype (female), and paratypes taken from moss and lichens, Leslie Valley track, 3000 feet elevation, 24th February, 1948. Coll. J. T. Salmon.

This species is very distinct and easily separated from the other peloridiids by the short frontal membrane of head. The hind margins of head on each side are obliquely narrowed anteriorly, which places the eyes a little distance in front of the anterior margins of paranota.
