Megarididae

provided by wikipedia EN

Megarididae is a family of true bugs in the superfamily Pentatomoidea. The family consists of a single extant genus Megaris with about 16 species restricted to the Neotropical Realm and a fossil is known from Dominican amber.

Bugs in the family are small (< 5 mm long) and are beetle-like, convex and shiny. The family can be identified by an enlarged scutellum that covers the abdomen and wings entirely and the legs have two tarsal segments. The extant genus Megaris has the second tarsal segment much smaller than the first. The ocelli are ovoid-elliptical and the eyes are constricted. The antennae are four-segmented. They are smaller than the somewhat similar members of the Canopidae which have however slightly larger, have three tarsal segments, and have the lateral pronotal margins meeting in a rounded arc. A fossil species from 20 to 15 mya amber has been described as Minysporops dominicanus.[1][2][3]

Megarididae ( Italian )

provided by wikipedia IT

Megarididae McAtee & Malloch, 1928, è una famiglia di insetti Pentatomomorfi dell'ordine Rhynchota Heteroptera, superfamiglia Pentatomoidea.

Descrizione

Sono insetti di piccole dimensioni. Il mesoscutello è grande e ricopre quasi completamente l'addome e le emielitre.

Sistematica e diffusione

La posizione sistematica di questa famiglia è controversa. L'inquadramento al rango di famiglia fa capo alla revisione di SCHUH & SLATER (1995) [1]. Secondo altre fonti il raggruppamento sarebbe una sottofamiglia dei Pentatomidae o dei Thyreocoridae, quest'ultima in realtà portata al rango di sottofamiglia nello schema tassonomico di SCHUH & SLATER.

Megarididae ( Norwegian )

provided by wikipedia NO

Megarididae tilhører gruppen Pentatomoidea, en undergruppe av tegene, en gruppe av nebbmunner. De har det til felles at munndelene er sugende og at de suger opp næringen. De lever av plantesaft fra planter og trær.

Utseende

Små, svarte teger. I likhet med flere andre grupper av Pentatomoidea dekker scutellum så godt som hele bakkroppen. De er hvelvede, blanke, kraftig punkterte og minner om biller av familien Leiodidae.

Levevis

Megarididae har ufullstendig forvandling, overgang fra nyklekt larve til det voksne kjønnsmodne insektet går gradvis gjennom flere nymfestadier. I alle fall noen av artene er knyttet til planter i myrtefamilien (Myrtaceae).
