Henicocoris monteithi is the only species of the genus Henicocoris , in turn, only the bugs - Family Henicocoridae is. 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.

features

The bugs have an elongated, egg-shaped body. Your head is directed forward and the cheek plates (bucculae) that border the beak groove are short. Point eyes ( Ocelli ) are formed. The antennae and also the labium are four-part. The trapezoidal pronotum is wider than it is long. The scent glands on the metathorax have receded, evaporation areas and peritremata (ring-shaped sclerites that surround the respiratory openings) are formed. The thighs ( femora ) of the front legs are not thickened and the tarsi on all three pairs of legs are tripartite. The Hemielytren have regressed membranes and are similar to wing covers with the beetles adapted missing hind wings. The setae have a greatly raised, granular base. On the abdomen, the seams of the sterna are fully developed and extend to the side edge of the abdomen. All spiracles on the abdomen are ventral . The animals have an arrangement of the trichobothria on the abdomen that is unique in the bugs : on the third and fourth sternum there is one submedial and no trichobothria on the side, no trichobothria are formed on the fifth sternum, on the sixth and seventh there are two trichobothria caudal to the stigmas. The lateral edges of the abdomen ( connexiva ) are evenly rounded and have segmented inner laterotergites on the second to fourth abdominal segments . In females, the seventh sternum is split and the ovipositor is fringed. The spermatheca is absent in the males. The nymphs have their scent gland openings on the abdomen between the fourth and fifth as well as the fifth and sixth tergum .

distribution

Henicocoris monteithi occurs in southern Victoria , in the temperate forests of the Otway Ranges and the southern coastal areas of New South Wales in Australia.

Way of life

Little is known about the way of life of Henicocoris monteithi . So far, the animals were caught at night when they were walking on dead wood lying on the ground and directly on the ground in moderately tempered forests.

Taxonomy and systematics

Thomas E. Woodward described the species in 1968 and placed it in the newly described subfamily Henicocorinae to the ground bugs (Lygaeidae). Mainly due to the similarities of the Trichobothria on the abdomen and the lack of spermatheca, he suspected a close relationship to the Idiostolidae and Oxycarenidae , the latter family also being considered a subfamily of the ground bugs. The current classification of the species was created in 1997 after a revision of the Pentatomomorpha with a focus on the Lygaeoidea by Thomas J. Henry. He reclassified the subfamily Henicocorinae and placed them in the family rank. He regards the Idiostolidae as a sister group and placed these two families in the new superfamily Idiostoloidea .
