LopodytesRondani 1867 [5] is a genus in the family Reduviidae, the assassin bugs. Members of the genus have been unofficially assigned the common name grass assassin bugs, [6] but generally this name remains meaningful only to naturalists, because these insects have been too well camouflaged to raise robust public awareness.

Description

Lopodytes species are small-to-medium-sized bugs, measuring between 10 and 20 mm in length. They are however very gracile and elongate in build, with nearly parallel sides, so they are far less massive than most insects of a similar bodily length. Usually they occur in savanna grass and similar vegetation, but on a level surface they generally adopt a very horizontal posture that emphasizes their resemblance to the thread assassins, the Emesinae. They easily may be confused with the Emesinae, but they are somewhat less gracile, typically 50% to 100% larger in linear measurement, and unlike the Emesinae, they do not have raptorial front legs.

In color Lopodytes species generally are a range of dusty greyish yellows to browns, shades that combine with their shape to make them inconspicuous in the partly dried tussock grasses that they normally inhabit. They probably are noticed far less often in the field than when they come to lights at night in certain seasons.

Etymology

The name Lopodytes could well be a source of confusion. It might refer to the Ancient Greek root λοπος, meaning bark or covering, plus δυτης, a diver, [7] suggesting a creature that hides under coverings, but it might more likely derive from λοποδυτατ, an old word for a robber that stripped the clothing off victims. [8]

Furthermore, there is a genus of ducks, Lophodytes which is sufficiently similar in spelling to cause either confusion in reference or errors in typing.

Biology

The biology of Lopodytes species has not been much studied. They appear to be predators of small insects, typical of Reduviid specialised for life in tussock grasses in savanna-like areas. As a rule both sexes are winged, but wingless forms occur. [6] They have been reported to come to lights, but only occasionally. In those species for which observations have been recorded, the eggs are very elongate and are laid on grass stems either singly or in small clusters. [9]

Taxonomy and distribution

The genus Lopodytes is in the order Hemiptera, suborder Heteroptera, family Reduviidae, subfamily Harpactorinae. Some sources give the genus authority as Rondani, 1867, but others credit Stål, 1853, Ofv. Vet.-Ak. Fork. 10, p. 263. [2]

The genus is native to the savanna and near-savanna regions of Africa, mainly south of the Sahara.

The following species have been described, some within indicated ranges. [5] [10] [11]

<span class="mw-page-title-main">Reduviidae</span> Family of insects

The Reduviidae is a large cosmopolitan family of the suborder Heteroptera of the order Hemiptera. Among the Hemiptera and together with the Nabidae almost all species are terrestrial ambush predators; most other predatory Hemiptera are aquatic. The main examples of nonpredatory Reduviidae are some blood-sucking ectoparasites in the subfamily Triatominae. Though spectacular exceptions are known, most members of the family are fairly easily recognizable; they have a relatively narrow neck, sturdy build, and a formidable curved proboscis. Large specimens should be handled with caution, if at all, because they sometimes defend themselves with a very painful stab from the proboscis.

<span class="mw-page-title-main">Emesinae</span> Subfamily of true bugs

The Emesinae, or thread-legged bugs, are a subfamily of the Reduviidae. They are conspicuously different from the other reduviids by their very slender body form. They are stalking, predatory insects that can be collected on palm fronds, cliffs, spider webbing, or near lights at night. They walk on their mid and hind legs; the front pair is raptorial. Some groups specialize on spiders. Very little is known about emesines except that many species are found in the tropics. Pedro Wygodzinsky wrote the most recent revision of this group.
