Pseudomyrmecinae
Pseudomyrmecinae is a small subfamily of ants containing three genera of slender, large-eyed arboreal ants, predominantly tropical or subtropical The subtropical zones or subtropics are geographical zone, geographical and Köppen climate classification, climate zones immediately to the Northern Hemisphere, north and Southern Hemisphere, south of the tropics. Geographically part of the Ge ... in distribution. In the course of adapting to arboreal conditions (unlike the predominantly ground-dwelling myrmeciins), the pseudomyrmecines diversified and came to occupy and retain a much wider geographic range. Pseudomyrmecines consists of 230 described species in three genera. Among those, 32 species live in plant domatia, making them the most diverse plant-occupying ant group worldwide.

Pseudomyrmex
''Pseudomyrmex'' is a genus of stinging, wasp-like ants in the subfamily Pseudomyrmecinae. They are large-eyed, slender ants, found mainly in tropical and subtropical regions of the New World. Distribution and habitat ''Pseudomyrmex'' is predominantly Neotropical in distribution, but a few species are known from the Nearctic region. Most species are generalist twig nesters, for instance, '' Pseudomyrmex pallidus'' may nest in the hollow stems of dead grasses, twigs of herbaceous plants, and in dead, woody twigs. However, the genus is best known for several species that are obligate mutualists with certain species of ''Acacia ''Acacia'', commonly known as wattles or acacias, is a genus of about of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa, South America, and Austral ...''. Other species have evolved obligate mutualism with other trees; for example '' Pseudomyrmex triplarinus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tetraponera
''Tetraponera'' is a genus of ants in the subfamily Pseudomyrmecinae that are commonly known as slender ants and are characterized by their arboreal nature and slender bodies. The 96 described species of ''Tetraponera'' all of which live in hollow structures of plants and trees, such as thorns or branches; these hosts are known as myrmecophytes. ''Tetraponera'' species are closely related to the New World genus of ants '' Pseudomyrmex'', but differ in their relationships with host plants. Mutualisms and behaviour ''Tetraponera'' species are generally defined by the myrmecophytes they inhabit and the mutualistic relationship they share. These host plants always have hollow thorns or branches in which the ants can live and form a colony. Also, the myrmecophytes provide energy rich food sources such as extrafloral nectar and/or food bodies. All ''Tetraponera'' species have gut symbionts that allow them to digest amino acid-deficient food provided by their host plants; these gut ...

Pseudomyrmex Gracilis
''Pseudomyrmex gracilis'', also known as the graceful twig ant, Mexican twig ant, slender twig ant, or elongated twig ant, is a large, slender species native to Mexico and arid parts of the US. The workers are about in length and generally wasp-like in appearance and style of movement. Worker ants are bi-colored; the head and gaster (insect anatomy), gaster are dark, while the Antenna (biology), antennae, Insect mouthparts, mouthparts, Thorax (insect anatomy), thorax and legs are dull orange with dark shading. They often may be seen on vegetation, foraging for live insects or collecting Honeydew (secretion), honeydew from sap-sucking insects. If the colony ever finds themselves without a queen, the worker ants form dominance hierarchies by boxing with their antennae. This leads to a couple high ranking individuals which can lay eggs until a new queen returns.

Subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end botanical subfamily names with "-oideae", and zoological subfamily names with "-inae". Detarioideae is an example of a botanical subfamily. Detarioideae is a subdivision of the family Fabaceae (legumes), containing 84 genera. Stevardiinae is an example of a zoological subfamily. Stevardiinae is a large subdivision of the family Characidae, a diverse clade In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach t ... of freshwater fish.

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Tropical
The tropics are the regions of Earth surrounding the equator, where the sun may shine directly overhead. This contrasts with the temperate or polar regions of Earth, where the Sun can never be directly overhead. This is because of Earth's axial tilt; the width of the tropics (in latitude) is twice the tilt. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). Due to the overhead sun, the tropics receive the most solar energy over the course of the year, and consequently have the highest temperatures on the planet. Even when not directly overhead, the sun is still close to overhead throughout the year, therefore the tropics also have the lowest seasonal variation on the planet; "winter" and "summer" lose their temperature contrast. Instead, seasons are more commonly divided by precipitation variations than by temperature variations. The tropics maintain wide diversity of local climates, such as rain forests, monsoons, sa ...

Subtropical
The subtropical zones or subtropics are geographical zone, geographical and Köppen climate classification, climate zones immediately to the Northern Hemisphere, north and Southern Hemisphere, south of the tropics. Geographically part of the Geographical zone#Temperate zones, temperate zones of both hemispheres, they cover the middle latitudes from to approximately 35° to 40° north and south. The horse latitudes lie within this range. Subtropical climates are often characterized by hot summers and mild winters with infrequent frost. Most subtropical climates fall into two basic types: humid subtropical climate, humid subtropical (Köppen climate classification: Cfa/Cwa), where rainfall is often concentrated in the warmest months, for example list of regions of China, Southeast China and the Southeastern United States, and Mediterranean climate, dry summer or Mediterranean climate (Köppen climate classification: Csa/Csb), where seasonal rainfall is concentrated in the cooler ...

Domatia
A domatium (plural: domatia, from the Latin "domus", meaning home) is a tiny chamber that houses arthropods, produced by a plant. Ideally domatia differ from galls in that they are produced by the plant rather than being induced by their inhabitants, but the distinction is not sharp; the development of many types of domatia is influenced and promoted by the inhabitants. Most domatia are inhabited either by mites or ants, in what can be a mutualist relationship, but other arthropods such as thrips may take parasitic advantage of the protection offered by this structure. Domatia occupied by ants are called myrmecodomatia. An important class of myrmecodomatia comprise large, hollow spines of certain acacias such as '' Acacia sphaerocephala'', in which ants of the genera '' Pseudomyrmex'' and '' Tetraponera'' make their nests. Plants that provide myrmecodomatia are called myrmecophytes. The variety of the plants that provide myrmecodomatia, and the ranges of forms of such domatia ...
