Le nom de Motschulsky exprime beaucoup mieux la coloration typique de cette espece que celui plus ancien de F. Smith.
De deux femelles portant des moignons d'ailes, l'une est normale, l'autre a la tete. plus petite, depourvue d'ocelles. Deux autres exemplaires ressemblent a de grosses ouvrieres ayant le mesonotum tres developpe, dont la portion scutellaire fait saillie en arriere.
M. le professeur A. Forel a decrit, dans le grand ouvrage de Grandidier, sous le nom de T. albipes , une forme de Madagascar qui merite d'etre separee comme sous-espece distincte ( Foreli , n. subsp. ). Elle differe du type indien et malais par ses antennes un peu plus courtes, dont le scape depasse a peine le bord occipital, et par ses antennes et ses pattes entierement testacees. Chez le type, le scape depasse notablement le bord occipital et les pattes sont d'un brun fonce, avec les trochanters, genoux et tarses d'un jaune pale; les scapes sont noirs, le flagellum souvent roussatre.
- Vrijburg, Bloemfontein. Identique aux exemplaires de Madagascar, sur lesquels j'ai fonde cette sous-espece.
Indische Art.
Das nahezu totale Fehlen von Dolichoderiden in der afrikanischen Fauna ist einer ihrer auffaelligsten Zuege. Ich kenne keine einzige Art dieser Subfamilie, die der afrikanischen Fauna eigen waere. Ebensowenig gibt es eigene afrikanische Prenolepis-Arten, waehrend Madagascar sehr reich an eigenen Arten dieser Gattung ist.

Technomyrmex albipes, commonly known as the white-footed ant,[2] is a species of ant first described in 1861 from Sulawesi, Indonesia by the British entomologist Frederick Smith.[3] Invasive pest ants in Florida, previously identified as T. albipes, have now been separated as Technomyrmex difficilis, both forming part of a species complex with a worldwide distribution.[4]
T. albipes is a small black ant some 2 to 4 mm (0.08 to 0.16 in) long with the lower part of the limbs pale. Workers are chocolate-black with pale lower limbs, antennae with twelve segments and a flattened petiolar node.[1] It differs from T. difficilis in lacking the pair of setae (bristles) that that species has on the back of its head.[5]
The white-footed ant is native to the Indo-Pacific area, and has been introduced into Australia, Africa, North America, the Caribbean and parts of Asia. It inhabits dry forests and open locations. Tent-like nests are made out of debris in trees, bushes, rotten logs, under rocks, in leaf litter and similar places. It also nests in man-made structures such as wall cavities and attics.[1]
The colony structure of this ant is unusual; there are both winged and wingless males, and three types of female, queens, intercastes and workers. New colonies are founded when winged males copulate with winged females after a nuptial flight. These females then shed their wings, find a suitable nesting site and start laying eggs, but their function in the colony is later taken over by intercastes. These females differ from workers in having spermathecae (sperm storage organs) and are mated by wingless males inside the colony. They are responsible for most of the reproduction that takes place in the colony. The queen is larger than other members of the colony and lays both fertilised and unfertilised eggs throughout her life, but the colony continues in existence after she dies. So successful is this reproductive strategy that colonies grow to very large sizes, sometimes containing millions of individuals, and may occupy multiple nest sites.[1]
The white-footed ant forages widely, entering dwellings and scavenging in kitchens and other rooms where it is considered a pest. It is largely arboreal and feeds on the honeydew of sap-sucking insects such as aphids, mealybugs, and scale insects. For this purpose it protects the insects and drives off predators, thereby encouraging the insects which may be agricultural pest species; the mealybug Dysmicoccus brevipes for example transmits pineapple wilt disease in Sri Lanka, and biological control of the mealybug has proved difficult because of the activities of the ant. Similarly in South Africa, the ant has encouraged outbreaks of the red scale insect (Aonidiella aurantii),[1] a major pest of citrus in the country.[6]

Technomyrmex albipes (лат. ) — вид муравьёв рода Technomyrmex из подсемейства долиходерины (Dolichoderinae, Tapinomini). Инвазивный вид.
Юго-Восточная Азия. Инвазивный вид, развезённый по всему миру, включая такие регионы, как Афротропика, Северная Америка, Мадагаскар, Австралия[2][3][4][5].
Мелкие земляные муравьи (длина менее 3 мм), в основном коричневато-чёрного цвета (лапки светлее). От близких видов (Technomyrmex difficilis) отличается отсутствием щетинок на затылочной части головы. Усики самок и рабочих 12-члениковые (у самцов антенны состоят из 13 сегментов). Жвалы рабочих многозубчатые (примерно с десятью зубцами). Нижнечелюстные щупики, как правило, 6-члениковые, нижнегубные щупики состоят из 4 сегментов (формула 6,4). Голени средних и задних ног с одной апикальной шпорой. Проподеум без зубцов. Стебелёк между грудкой и брюшком состоит из одного небольшого сегмента (петиоль низкий, редуцировнный, без чешуйки или узелка). Жало отсутствует. Гнездятся в гнилой древесине[2][6][3][7].
