The Obriminae are the most species-rich subfamily of the Phasmatodea family Heteropterygidae native to Southeast Asia. It is divided into two tribe. [2]
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.). [3] 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 [4] 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. [5] 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 The name Therameninae was withdrawn again in 1929 by Klaus Günther and is therefore a synonym for Obriminae. In 1939 the Obriminae, now referred to as a subfamily, were split up by James Abram Garfield Rehn and his son John William Holman Rehn into the Obrimini and Datamini tribes. [6] Günther transferred both tribes to the Heteropteryginae subfamily in 1953. [7] In 2004 Oliver Zompro elevated this subfamily to the rank of a family and the tribe included to the rank of subfamilies or, in the case of the Anisacanthini, to the rank of a family of their own. He divided the new subfamily Obriminae into three tribes. In addition to the Obrimini, these were the Eubulidini and the Miroceramiini. [8] The two new tribes were synonymed in 2016 by Frank H. Hennemann et al. and 2021 by Sarah Bank et al. with the Obrimini. The 2016 by Hennemann et al. established tribe Tisamenini was synonymous in 2021. With the establishment of the Hoplocloniini, the anatomical peculiarity of the secondary ovipositor of the genus Hoploclonia was taken into account. This special status was also confirmed by genetic analysis investigations. [2] [9]
Thus the Obriminae consist of two valid tribes. One is the monotypical tribus Hoplocloniini, with the only genus Hoploclonia and the other tribus is Obrimini with now 14 genera and 70 valid species. [10] [11]
The Obriminae can reach very different sizes with almost 3 centimetres (1.2 in) in Tisamenus hebardi and up to 13 centimetres (5.1 in) in length in Trachyaretaon carmelae . The sensory fields present in all Heteropterygidae are to be found in pairs in the Obriminae in the front area of the prosternum. In adult females the abdomen is widened and significantly increased by the eggs that are permanently and often produced in large numbers. Their abdomen ends in a pointed secondary ovipositor that surrounds the actual ovipositor. It is ventral formed from the eighth abdominal sternite, which is here named subgenital plate, [12] or also called operculum. Dorsally it consists in the Obrimini by the eleventh abdominal tergum called the supraanal plate or Epiproct and in the Hoplocloniini from the tenth tergum. This peculiarity means that the secondary ovipositor must have developed independently of one another twice within the Obriminae. [2] The abdomen of the smaller males is round in cross-section and thinnest in the middle of abdomen. Except in Miroceramia westwoodii and in rudiments in Pterobrimus depressus , the only known representatives of their genera, the Obrimini have no wings. [9] [13] [14] [15] [16]
The body is often covered with numerous spines, more or less blunt thorns or tubercles, which can be found mainly on the upper side of the head and thorax. Their characteristics can be very different, and their arrangement is mostly species-specific and is often used to identify and delimit the species. This method, known as acanthotaxy, was developed in 1939 by Rehn and Rehn for the Obriminae. [6]
The distribution area of the Obriminae includes Borneo, where both Hoplocloniini and Obrimini can be found. The latter are also widespread to the east on the Philippines, Sulawesi, most of the Moluccas islands, New Guinea and Viti Levu. [2] [9]
Sungaya is a genus of stick insects which is endemic to the Philippine island of Luzon.
The Heteropterygidae is a family of stick insects belonging to the suborder Euphasmatodea. Species can be found in Australasia, East and Southeast Asia. About 150 valid species have been described.
Sungaya inexpectata is a species of stick insects and the type species of genus Sungaya. The species name is derived from the Latin as "inexpectatus" and means "unexpected". Its common name is sunny stick insect, derived from the less commonly used sungay stick insect, which in turn refers to the place where the species was found.
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.
Heteropterygini is the only tribe within the subfamily of the Heteropteryginae. 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.
Hoploclonia is the only genus of the tribe Hoplocloniini and brings together relatively small and darkly coloured Phasmatodea species.
The Obrimini are the most species-rich tribe of the Phasmatodea family of the Heteropterygidae native to Southeast Asia.
Mearnsiana is a genus of stick insects, which is native to the Philippine islands Mindanao, Leyte and Dinagat.
Mearnsiana bullosa, occasionally referred to by the common name Manobos stick-insect,is a species of stick insect in the family Heteropterygidae. It is native to the Philippine islands of Mindanao and Leyte. Until 2023 it was the only described representative of the genus Mearnsiana.
The genus Tisamenus native to the Philippines combines small to medium-sized species of stick insects.
Aretaon is a genus of stick insects native to Borneo and the Philippine island Palawan.
Trachyaretaon is a genus of stick insects native to the Philippines.
Brasidas is a genus of stick insects that is native to the Philippines and is named after the Spartan general Brasidas
Obrimus is a stick insect genus native to the Philippines. It is type genus for the tribe and the subfamily in which it is listed.
Eubulides is a stick insect genus native to the Philippines.
Theramenes is a genus of medium-sized stick insects in the tribe Obrimini, which is native to the Philippines and to the Indonesian Talaud Islands.
Aretaon asperrimus is a species of insect in the Aretaon genus of the Phasmatodea order. The sometimes used common name thorny stick insect is a bit misleading, since the species does not correspond to the typical stick-like habitus and many other species are thorny as well.
Stenobrimus is a genus of medium-sized stick insects native to the Philippines.
Pterobrimus is a monotypic genus of stick insects (Phasmatodea), containing the species Pterobrimus depressus, which is native to Fiji.
Obrimus bicolanus is a stick insect species from the family of the Heteropterygidae native to the southeast of the Philippine island of Luzon, more precisely in the Bicol Region.
