Specimen Label

The types of the only species of the genus, Overbeckia subclavata, were reported as being collected from nests in hollow bamboo and the hollow branches of a mango tree.


The short sub-quadrate antenna combined with a sub-truncate head (similar to Colobopsis) are important diagnostic features for this monotypic genus. Their resemblance to Camponotus led Bolton (2003) to suggest revisionary work will lead to Overbeckia becoming a junior synonym of that diverse genus.  


Only known from Singapore.

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.



Fuhler 12-gliedrig, Einlenkung vorn Hinterrande des Clypeus abgeruckt, GeiBel gegen das Ende verdickt, die vorletzten Glieder schwach quer. Stirnleisten schwach geschweift, nach ruckwarts divergierend, Stirnfeld dreieckig. Vorderkopf etwas abgestutzt, Clypeul schwach konvex, Clypeal und Antennalgrube getrennt, Mandibeln dreieckig und gezahnt ; Kiefertaster 6-gliedrig, das 1. Glied sehr klein; Lippentaster 4-gliedrig. Augen in der Mitte der Kopfseiten, Punktaugen fehlen. Thorax ahnlich Calomyrmex, oben ziemlich flach, mit deutlicher Promesonotal und feiner Mesoepinotalsutur, an dem Epinotum seitlich eingeschnurt, Pronotum vorn und Meso und Epinotum seitlich gerandet. Petiolus mit senkrechter Schuppe. Pumpmagen wie bei Prenolepis longicornis, mit kurzen, schwach gebogenen Kelchblattern. Kein Dimorphisrnus.


Wie der (worker symbol) Schuppe des.Petiolus niedriger und dicker, Epinoturn seitlich nicht gerandet, Epinotumwinkel gerundet rechtwinklig. Flugelgeader wie bei Camponotus, mit langgestreckter Cubital und geschlossener Radialzelle, aber ohne Discoidalzelle. Drei Punktaugen.


Kopf hinter den Augen halbkreisformmig, mit den Augen etwa so breit als ohne die Mandibeln lang. Fiihler 13-gliedrig, mit langem Scapus, aIle GeiBelglieder etwas langer als breit; Kieferund Lippentaster wie beim (worker symbol); Mandibeln mit ungezahntem Kaurande. Schuppe niedrig und dick. AuBere Genitalanhange kurz, auBere Klappen nicht dornformig.


Puppen bedeckt.


This genus was named after Hans Friedrich Overbeck in honor of his contributions to myrmecology. Viehmeyer noted that Overbeck had meticulously studied, packaged, shipped and made notes about a large number of ant species that formed the subject matter of his paper "Ameison von Singapore." Viehmeyer then notes that these research efforts were halted by WWI and he both praises and thanks Overbeck for his work.
