Very little is known about the biology of Australian Nerthra species.

Entire body covered with short, broadly clavate bristles, bristles pale and especially dense on pronotum and on the elevations of the head. Received Oct 14; Accepted Apr It is divided into two subfamilies, Gelastocorinae and Nerthrinae.

Body large size for the genus. Body light brown, front of head provided with five large, rounded tubercles, four of which are flatted on top and densely covered with short clavate bristles; ocelli absent.

Toad bugs are hemiptrea predators and scavengers feeding on a variety of small aquatic and semi-aquatic insects. Lingnan Science Journal 12 Supplement: Apart from the no doubt considerable physical protection that the armour affords them, the layer of sand renders them effectively invisible on the ground unless they move at the wrong moment.

Notes on some toad bugs from China (Hemiptera, Heteroptera, Gelastocoridae)

Aetalionidae Cicadellidae leafhoppers Melizoderidae Membracidae typical treehoppers, thorn bugs Myerslopiidae. Dedicated naturalists volunteer their time and resources here to provide this service. In the shape of the pronotum it would seem to be closely related to N. Gelastocoridae catch their prey by leaping on top of them and grasping them with their modified front legs.


Abstract The three species of Nerthra Say, Hemiptera: Abdominal sternites of female nearly symmetrical except for posterior margin of last sternite, which is slightly emarginated, but with apex slightly convex just below the lobes of the ovipositor, the latter somewhat rounded and the left one overlapping the right.

Hebridae velvet water bugs. Description from Todd Nova Guinea, New Series The lateral margins of the pronotum markedly asymmetrical, pronotum about as wide at anterior third as at the level of the transverse furrow.

Ninth sternite wider than long, not as long as eighth sternite; seventh sternite sternite about half as long as eighth sternite; fifth sternite very short medially.

In gelasocoridae, abdomen nearly symmetrical. Hemelytra not extending to the end of the abdomen, membrane well developed; embolium with the basal half of the lateral margin nearly straight, not expanded laterally at middle. Nieser N, Chen PP.
