Adetomyrma
''Adetomyrma'' is a genus of ants endemic to Madagascar. Workers of this genus are blind. The type species '' Adetomyrma venatrix'' was described in 1994, with the genus being an atypical member of its tribe, the Amblyoponini. This tribe includes the Dracula ants, members of which can feed on the hemolymph of larvae and pupae. Taxonomy ''Adetomyrma'' was first described as a Malagasy endemic monotypic genus by Ward in 1994. Ward (1994) assigned this genus to Amblyoponini within the subfamily Ponerinae on the basis of the worker morphology of the type species ''Adetomyrma venatrix''. Later, Bolton (2003) raised this tribe to subfamily status as Amblyoponinae Amblyoponinae is a subfamily of ants in the poneromorph subfamilies group containing 13 extant genera and one extinct genus. The ants in this subfamily are mostly specialized subterranean predators. Adult workers pierce the integument (non letha ....

Adetomyrma Aureocuprea
''Adetomyrma aureocuprea'' (from Latin ''aureus'', "golden" and ''cupreus'' "coppery", referring to the body coloration) is a species of ant endemic to Madagascar. Description ''Adetomyrma aureocuprea'', only known from males, is easily separable from the other ''Adetomyrma'' males by the yellowish body color, no mesoscutal notaulus, poorly developed subpetiolar process, lack of posterodorsal projection or lobe on the paramere, short hairs on the compound eye, and vestigial parapsidal line. The males of ''Adetomyrma aureocuprea'' display remarkable morphological variation in, for example, the size of the eye and ocelli, head shape, mesonotal shape, petiolar shape, and hairs on body surface. Sympatry ''A. aureocuprea'' is completely sympatric with '' A. bressleri'', '' A. caputleae'', '' A. goblin'', and '' A. venatrix'', and has been collected within a 20 km radius of '' A. cilium'' and within a 70 km radius of '' A. caudapinniger''.

Adetomyrma Venatrix
''Adetomyrma venatrix'', more commonly known as the Dracula ant, so named because of its grisly feeding habits of drinking the blood of its young, is an endangered species of ants endemic to Madagascar. Workers of this species are blind. The species was described as the type species of '' Adetomyrma'' in 1994, with the genus being an atypical member of its tribe. Description ''Adetomyrma venatrix'' was described on the basis of specimens belonging to the worker caste collected from Zombitse Forest, in western Madagascar. The key characteristics of the species was the absence of a clear petiole when viewed from above due to the third abdominal tergite (the sclerite on the dorsal side) lacking a differentiated pretergite. The gaster is large and without constrictions. The ant is blind and has a long sting. It was placed with reservations in the tribe Amblyoponini as it lacks the typical characters of the group. Later studies considered them as being close to the ancestral members ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adetomyrma Caudapinniger
''Adetomyrma caudapinniger'' (from Latin ''caudapinna'', "tail fin", and ''gero'', "have", referring to the distinctive paramere) is a species of ant endemic to Madagascar. Description ''Adetomyrma caudapinniger'' is only known from males. The male is distinguished easily from other ''Adetomyrma'' males by its bilobed paramere and 2,2 palpal formula. These characters, as well as those observed in the aedeagus An aedeagus (plural aedeagi) is a reproductive organ of male arthropods through which they secrete sperm from the testes during copulation with a female. It can be thought of as the insect equivalent of a mammal's penis, though the comparison ..., are unique to ''Adetomyrma caudapinniger'', and a separation of this species from the remaining ''Adetomyrma'' species is clear and consistent. For example, '' A. aureocuprea'', which is superficially similar to ''A. caudapinniger'', has a simple paramere and a 3,3 palpal formula. References * * Amblyoponinae Blind ...

Adetomyrma Cassis
''Adetomyrma cassis'' (from Latin ''cassis'', "helm", referring to the shape of its genital capsule) is a species of ant endemic to Madagascar. Description ''Adetomyrma cassis'' is only known from a single male collected in the Ambatovaky Reserve, Madagascar. The male of ''A. cassis'' is distinguished easily from other ''Adetomyrma'' males by a distinct and flatted projection on the posterior portion of the paramere Parameres ('side parts') are part of the external reproductive organs of male insects and the term was first used by Karl Wilhelm Verhoeff, Verhoeff in 1893 for the lateral genital lobes in Coleoptera. The primary phallic lobes which appear in th .... This projection is not separated from the paramere by a deep notch as in '' A. bressleri''. This genital character observed in ''Adetomyrma cassis'' is completely unique and sufficient to regard this male as a distinct species.

Adetomyrma Cilium
''Adetomyrma cilium'' (from Latin ''cilium'', "eyelash", referring to the long hairs on its compound eye) is a species of ant endemic to Madagascar. Description ''Adetomyrma cilium'' is only known from males. The male of ''A. cilium'' is distinguished easily from the other ''Adetomyrma'' males by a combination of long hairs on the eye, long suberect hairs on the anterior surface of the mesofemur, and a well-developed subpetiolar process. The species is relatively similar to '' A. clarivida'', but differs in the mesofemur hairs and development of the subpetiolar process. Additionally, these species differ in the shape of the aedeagus An aedeagus (plural aedeagi) is a reproductive organ of male arthropods through which they secrete sperm from the testes during copulation with a female.

Amblyoponinae
Amblyoponinae is a subfamily of ants in the poneromorph subfamilies group containing 13 extant genera and one extinct genus. The ants in this subfamily are mostly specialized subterranean predators. Adult workers pierce the integument (non lethally) of their larvae and pupa to imbibe haemolymph, earning them the common name Dracula ant. Identification Amblyoponinae is characterized by these worker characters: eyes small or absent, situated behind midlength of side of head; anterior margin of clypeus with specialized dentiform setae; promesonotal suture flexible; petiole very broadly attached to abdominal segment 3 and without a distinct posterior face; postpetiole absent; sting present and well developed. Systematics The subfamily was formerly considered a tribe within Ponerinae, but was elevated to its own subfamily in 2003 when Barry Bolton divided Ponerinae into six subfamilies. *Amblyoponinae Forel, 1893 ** Amblyoponini Forel, 1893 *** ''Adetomyrma'' Ward, 1994 *** '' Ambl ...

Ant Genera
Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from vespoid wasp ancestors in the Cretaceous period. More than 13,800 of an estimated total of 22,000 species have been classified. They are easily identified by their geniculate (elbowed) antennae and the distinctive node-like structure that forms their slender waists. Ants form colonies that range in size from a few dozen predatory individuals living in small natural cavities to highly organised colonies that may occupy large territories and consist of millions of individuals. Larger colonies consist of various castes of sterile, wingless females, most of which are workers (ergates), as well as soldiers (dinergates) and other specialised groups. Nearly all ant colonies also have some fertile males called "drones" and one or more fertile females called "queens" (gynes). The colonies are described as superorganisms because the ants a ...
