The Cryptorhamphidae are a family of bedbugs (Heteroptera) within the suborder Pentatomomorpha . Until the revision of the Pentatomomorpha with a focus on the Lygaeoidea by Henry in 1997, it was a subfamily of the ground bugs (Lygaeidae) and was then placed in the family rank. It includes two genera and four species.

features

The bugs have an elongated physique. Its head is square and the buccules are elongated. The sensors are as well as the lip of four members. Pointed eyes ( Ocelli ) are formed and are separated by a seam in between. On the metathorax there are scent glands whose evaporation area and peritrema are well developed. The hemielytres are structured point-like, their membrane has four to six longitudinal veins. The hind wings have a hamus. All the spiracles are dorsal on the abdomen . Trichobothria are only present on the fifth and sixth sternum on the abdomen . The ventral side of the body has a point structure.

distribution

The family is only widespread in the Australis and occurs from Fiji to southeastern Australia. All four species occur only in the temperate latitudes of Australia and are absent there in the tropics and subtropics, although Gonystus nasutus is also common in Fiji.

Way of life

The way of life of the animals is hardly known. Species of the genus Cryptorhamphus have been found on plants; often on the seed pods of species from different plant families, such as. B. of foxtail plants (Chenopodiaceae), legumes (Fabaceae), sweet grasses (Poaceae), mimosa plants (Mimosaceae) and myrtle plants (Myrtaceae). Gonystus grossi lives on grasses in tufts of grass.

Taxonomy and systematics

In 1860 Carl Stål described the genus Cryptorhamphus in the subfamily Cymida, which at that time still belonged to the ground bugs . Walker placed them in their own tribe, Cryptorhamphina, in 1872, which Stål reversed in 1874. This view was also followed by Barber in 1956 and Slater in 1964. Štys placed them in their own tribe in 1967, and Hamid in 1971 in their own subfamily, already together with the second genus Gonystus . He suspected a distant relationship with the Cymidae (at that time still a subfamily of the ground bugs). The current classification of the group was created in 1997 after a revision of the Pentatomomorpha with a focus on the Lygaeoidea by Henry. He reclassified the group, which had been considered a subfamily of the ground bugs, and placed them in the family rank.

The family includes the following genera and species:
