Hypsipteryx is the only genus of the family Hypsipterygidae within the bugs -Teilordnung dipsocoromorpha . Four species of it areknown, one of which was first described in 2007.

features

The bugs are two to three millimeters long and are relatively flattened dorsally . They look very similar to representatives of the net bugs (Tingidae).

Your head is directed forward, all parts of the head capsule are sharp-edged. The fourth segment of the antennae is comparatively short and thick, the third segment is very long. The labium is straight and extends to or almost to the base of the metasternum. The first, second and fourth segments are clearly recognizable and very short, the third segment is very long. The pronotum has extended margins and has three longitudinal grooves. The tegminalen forewings are broad and flat. Your clavus is sharply demarcated and there is neither a costal nor a medial interruption. All wing veins are raised and form nine large cells. The entire forewings are finely structured like a net. The legs are noticeably slim. The tarsi are two-part in both sexes. Most of the sterna of the abdomen are divided into medio- and laterotergites. The spiracles are located on the laterotergites on the second to eighth abdominal segments of the males and third to seventh abdominal segments of the females. The last abdominal segments in front of the genitals are symmetrical in the males, the pygophores (the extension of the ninth abdominal segment in the males), the paramere and the laterotergites on the ninth abdominal segment are asymmetrical; the latter are in the form of body tags. The phallus is complex and has a long, coiled gonopori process. The females have a large subgenital plate on the seventh abdominal segment and a fully developed, but structurally modified, ovipositor and a developed spermatheca .

The resemblance to net bugs, the thin legs and the straight labium are autapomorphies of the family.

Occurrence

The family is paleotropic .

Way of life

The fully winged species Hypsipteryx ecpaglus is known for catching light. The remaining flightless African species in the family were found in the litter or dead wood. The animals' delicate legs suggest that they cannot hop. Unlike the other representatives of the Dipsocoromorpha, the Hypsipteryx species, with the exception of Hypsipteryx vasarhelyii , have not yet been detected from Berles cases , which suggests a difference in the way of life.

Taxonomy and systematics

Drake first described the group in 1961 as a subfamily of the Dipsocoridae . She was raised to family rank by Pavel Štys in 1970. The following types are known so far:

Another fossil species is also known.
