Heteropterygidae
The Heteropterygidae is a family of stick insects belonging to the suborder Euphasmatodea. Species can be found in Australasia, East and Southeast Asia. More than 130 valid species have been described (at the end of 2020). Characteristics Size The Heteropterygidae include both very small and very large and massive species. The representatives of the Dataminae are consistently rather small. So ''Planispectrum'' species are only long. The largest Dataminae species, with a maximum length of , are within the genera ''Pylaemenes'' and ''Orestes''. While the subfamily Obriminae with almost in ''Tisamenus hebardi'' and up to in ''Trachyaretaon carmelae'' shows a wide range of sizes, the Heteropteryginae are considered rather large. Indeed, there are very large and massive species, such as the up to long ''Heteropteryx dilatata'' known as Malayan jungle nymph, but also small species such as those in the male sex only long ''Haaniella parva''.

Orestes (insect)
The genus ''Orestes'' combines relatively small and elongated Phasmatodea species from Southeast and East Asia. Characteristics The representatives of this genus are rather small with in the males and in females. Both sexes are always wingless and colored in different shades of beige to brown and often show high-contrast drawings with white areas, especially in younger females and female nymphs. Males are more of a single color in different shades of brown. The thorax is cylindrical or approximately cylindrical, unlike that of representatives of the genus ''Pylaemenes'', whose meso- and metanotum is flattened or slightly roof-shaped, with a clearly raised central and two lateral longitudinal keels. The mesonotum of the ''Orestes'' females is slightly widened to the rear and there are often two lateral longitudinal rows of tubercles. The legs and especially the femura of the forelegs often have clear edges. The abdomen of adult, egg-laying females is clearly enlarged towards ...

Obriminae
The Obriminae are the most species-rich subfamily of the Phasmatodea family Heteropterygidae native to Southeast Asia. It is divided into two tribe. Taxonomy The tribe Obrimini was created by Brunner von Wattenwyl in 1893 for the genera '' Obrimus'', '' Hoploclonia'', ''Tisamenus'', ''Pylaemenes'', ''Dares'' and ''Datames'' (today synonym to ''Pylaemenes'') (abbreviated there as Obrimi.). Lawrence Bruner raised the Obrimini to the rank of a family in 1915. Heinrich Hugo Karny renamed the Obrimini or the Obrimidae in 1923 to Therameninae. In the introduction to his work he justified the renaming by saying that Brunner von Wattenwyl and Josef Redtenbacher when naming the subfamilies they established – and as such he also considers the tribes described by both of them – not always taking into account the genera described first. At least in the case of the Obriminae this is not true, since both the genus ''Obrimus'' and ''Theramenes'' was built in 1875 by Carl Stål. The name The ...

Heteropteryx Dilatata
''Heteropteryx'' is a monotypic genus of stick insects containing ''Heteropteryx dilatata'' as the only described species. and gives its name to the family of the Heteropterygidae. Their only species may be known as jungle nymph, Malaysian stick insect, Malaysian wood nymph, Malayan jungle nymph, or Malayan wood nymph and because of their size it is commonly kept in zoological institutions and private terrariums of insect lovers. It originates in Malay Archipelago, more precisely on the Malay Peninsula and Borneo and is nocturnal. Description The females are much larger and wider than the males, reaching to in length and 30 to 65 g in weight, making them among the heaviest phasmids and extant insects. In addition to the typically lime green-colored females, there are also yellow and even more rarely red-brown females. Their two pairs of wings are both shortened. At rest, the green forewings, formed as tegmina, cover the somewhat shorter, strikingly pink-colored membra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dataminae
Datamini is the only tribe within the subfamily of the Dataminae from the order of the Phasmatodea. The representatives of this subfamily are on average not as large as those of the other two subfamilies belonging to the family of Heteropterygidae. Description Datamini species remain relatively small for phasmids. In females, the body length varies between 2.5 and 6 cm, depending on the species. The males remain somewhat smaller with a body length of less than 2 to a maximum of 5 cm. The presence of sensory areas, which is considered to be the autapomorphic characteristic of the Heteropterygidae, is fully developed in the Dataminae. With them there is a pair of these sensory fields on the Prosternum and a third in the middle behind it on the so-called (Pro-) Furcasternit. All species are wingless in both sexes. The females lack the secondary ovipositor typically developed in the other subfamilies at the end of the abdomen. Their abdomen ends bluntly. In adult females ...

Pylaemenes (insect)
''Pylaemenes'' is a genus of stick insects in the family Heteropterygidae and subfamily Dataminae. It combines small to medium-sized, often brightly colored Phasmatodea species. Their representatives are found in large parts of Southeast Asia. Characteristics The average size of representatives of this genus in the male sex is between and between in the females. All species are always wingless. The basic color of adult animals is usually a light beige or brown, which can be supplemented by almost white, brown or black markings depending on the species and gender. On the forehead, which becomes narrower towards the top, there are clear elevations that are differently designed depending on the type. The antennae are considerably longer than the femura of forelegs. One to three teeth can be found on the outer edge of the first antenna segment. The body surface is mostly covered with tubercles. In contrast to the genus ''Orestes'', the Meso- and Metanotum are flattened or sl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heteropteryginae
Heteropterygini is the only tribe within the subfamily of the Heteropteryginae (family Heteropterygidae; order Phasmatodea). With 19 representatives described, this subfamily includes the fewest species of the three subfamilies, but includes the largest and most striking species of the family. Characteristics Size and weight The representatives of the Heteropterygini are usually relatively large and heavy. Males become 2.5 to 13 cm long, females reach body lengths between 4.5 and 17 cm, with the larger species being clearly in the majority. Only the females of ''Haaniella parva'', '' Haaniella kerincia'' and ''Haaniella scabra'' remain smaller than 8.5 cm. The males of these species are at least 2.5 to 4.0 cm and a maximum of 3.7 to 5.7 cm long. The 14 to 17 cm long females of the ''Heteropteryx dilatata'' are not only the heaviest phasmids with 30 to 70 g, but are among the heaviest insects at all.

Obrimini
The Obrimini are the most species-rich tribe of the Phasmatodea family of the Heteropterygidae native to Southeast Asia. Description The Obrimini differ from their sister tribe the Hoplocloniini by the structure of the secondary ovipositor at the abdomen of the females, which surrounds the actual ovipositor. It is formed in the Obrimini dorsally from the eleventh abdominal tergum called supraanal plate or epiproct, while in the Hoplocloniini it originated from the tenth tergum. Distribution area The distribution area of the Obrimini extends from Borneo to the east and includes the Philippines, Sulawesi, most of the Moluccas and New Guinea. Farthest east lies with Viti Levu, the main island of the Fiji group, the distribution area of ''Pterobrimus depressus''. Taxonomy Brunner von Wattenwyl built in 1893 for the genera already described '' Obrimus'', '' Hoploclonia'', ''Tisamenus'', ''Pylaemenes'', '' Dares'' and ''Datames'' (today a synonym to ''Pylaemenes'') the t ...

Planispectrum
The genus ''Planispectrum'' combines very small and compact species from Southeast Asia. Characteristics ''Planispectrum'' is the smallest genus of the Dataminae. The males of the previously known species reach lengths of , the females are long. In addition to the small size, the flat body and the very short antennae, which are hardly longer than the femura of the forelegs, are characteristic of the genus. In all species the antennae are shorter than the legs as a whole. The first antenna segment (scapus) is always toothed. Tubercles or teeth can be seen on the top of the head. The pronotum is trapezoidally widened posteriorly. The Metanotum is square. The margins of thorax and abdomen may be serrated. The meta pleura have no spines. The abdominal segments are very short and wide. The ventrally located subgenital plate of the female is blunt and no longer than the dorsaly located operculum. The same is swollen and rounded. It shows a rounded lip at the end. The legs are very ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haaniella Parva
''Haaniella parva'' is a species of stick insect from the subfamily Heteropteryginae and belongs to the representatives of the genus '' Haaniella'' native to Sumatra. It is their smallest representative. Description ''Haaniella parva'' is the smallest species of the genus and thus also of the entire subfamily of Heteropteryginae. It has only a few spines and belongs to the species with greatly shortened wings in both sexes. The forewings, which are formed as tegmina, completely cover the short hindwings. The latter are transformed into stridulation organs and the sound they produce is used to ward off enemies. The females are usually relatively uniformly colored light to dark brown or almost black, but can also have light patterns on the thorax and abdomen. The nominate subspecies reaches a length of . They have eight distinct spikes on their heads. These are almost equally sized, conical anterior and posterior coronals on the crown, two similarly sized, blunt lateral coronals ...
