Joppeicus paradoxus is the only described kind of family Joppeicidae , in turn, only the superfamily Joppeicoidea within the bugs -Teilordnung cimicomorpha is.
features
The bugs grow to be about 3.0 millimeters long and resemble flower bugs . The top of the animals is slightly tuberculated. The compound eyes are relatively small and are located near the rear edge of the head. Point eyes ( Ocelli ) are formed. The first two links of the antennae are comparatively short, the fourth link has strong setae at the tip . In the rest position on the labium , the second and third limb are at right angles to each other. The first segment is very small, the third is about three times as long as the second and 1.5 times as long as the fourth. The bucculae , the cheek plates laterally delimiting the beak groove, cover the base of the labium. The pronotum is grooved on the side and has a center keel on the first two front thirds. The hemielytres are trough-shaped on the subcubital artery, R + M are raised and keel-shaped. The costal and medial folds are missing. The membrane lacks the stub called the "corial process" and has only weakly developed veins. The cross vein M-Cu is missing on the hind wings. The tarsi are two-part. The scent glands on the metathorax have paired reservoirs and openings (ostioles) that are far apart. The abdomen is extensively membranous at the connection to the thorax . It can be rotated 90 °. The first three terga are membranous, the second sternum is a narrow strip. The stigma is absent on the first abdominal segment ; on the second through eighth it is due to the sterna. In the nymphs , the scent glands are located on the abdomen at the front edge of the fourth to sixth terga. The females lack a functional spermatheca and their ovipositor is severely reduced. The phallus is designed as a sclerotized tube. The genital capsule is clearly defined, the paramers are symmetrical.
Many features of the species, such as the structure of the wings, the phallus and the large intersegmental membrane between the third and fourth abdominal segments, are autapomorphies .
Occurrence
The species is restricted to southern Israel and the course of the Nile and Blue Nile in Egypt and Sudan. The species was found mainly in the Nile Delta. They are mainly found in border areas, often in dusty places that are rarely visited by other insects. They have been found on the ground, under stones, in shallow caves and under bark, but also in colonies of flat bugs that lived with bats .
Way of life
The bedbugs live predatory on a variety of different prey. When the prey is attacked, the rostrum is carried straight in front of the body. When mating, the male first clings to the female's abdomen and rotates his abdomen on the large membrane between the third and fourth abdomen segment by 90 ° and moves his back under the abdomen of the female's abdomen. This is how the actual pairing then takes place.
Taxonomy and systematics
The genus Joppeicus was originally placed in the family of the bark bugs (Aradidae) by its first descriptor, Puton, later moved to the ground bugs (Lygaeidae) by Bergroth (1898) and finally raised to the family rank by Reuter in 1910. Reuter placed this in the superfamily Aradoidea, only Štys considered the family to be part of the Miriformes .
