Distribution

Bolton and Fisher (2011) - H. punctatissima is without doubt the world’s most accomplished ponerine tramp-species. Its range incorporates all tropical and subtropical zoogeographical regions, including most oceanic islands, and it also penetrates well into the temperate zones of both hemispheres where it is frequently synanthropic; for a brief synopsis of world distribution see Delabie & Blard (2002); European distribution is summarised in Seifert (2003).

It is a common introduced species in south and central Florida. First published Florida record: Smith 1933. (Deyrup, Davis & Cover, 2000.)

Regional Notes

Africa

Bolton and Fisher (2011) - H. punctatissima is very widely distributed in sub-Saharan Africa and appears relatively common. It is often retrieved from litter and topsoil samples in forests, and also from rotten wood, but it seems particularly frequent in areas disturbed by human activities, especially in gardens, plantations and crop fields.

Florida

Deyrup, Davis and Cover (unpublished) - This species occurs in small colonies in a variety of moist or well-drained habitats. In southern Florida it is often found in rotten logs and large grass tussocks, and especially in accumulations of organic matter, such as grass clippings or compost, often in open or disturbed sites. The key to the housefly-like success of H. punctatissima lies in its predilection for dung and various kinds of middens, which humans and their livestock supply in inexhaustible quantities. Delabie and Bland (2002) have compiled a whole series of breeding sites, ranging from earthworm cultures to heaps of chicken manure, and suggest that this ant emerged out of Asia following the domestication and extensive use of horses.

The tendency for H. punctatissima to produce disproportionately large numbers of dispersing females is appropriate for a species that colonizes resource-rich sites that are often ephemeral. This dispersal, in turn, leads to problems with stinging alates. Queens often fly in large numbers, stinging when they land on human skin if they are touched, trapped under clothing, or stuck in sweat. We have had a number of complaints about this species, mostly from west-central Florida (Deyrup, Davis & Cover, 2000).

New Mexico

Mackay and Mackay (2002) - Habitat. Riparian zones in arid habitats. Biology. This species nests under stones or in the soil.

Fennoscandia, Denmark and the British Isles

This species is often imported with plant material. However, it has long been resident in North Europe and head capsules presumed to be of this species have been recorded from sewage mud deposited about 1500 years ago in North England. Most recorded occurrences are from heated premises such as bakehouses and conservatories. However, colonies have been recorded outside in England, Ireland, Denmark, Norway and Finland from fermenting rubbish dumps, waste tips, sawdust heaps and deep mines away from buildings. Queens and sometimes workers have also been captured individually by general herbage sweeping or in woodlands. Occurrences in Denmark and Fennoscandia have been summarised by Skott (1971). Colonies are often populous and many alate queens may be produced to fly out during August and September. The apterous males remain in the nest. This species, as with most Ponerini, is mainly carnivorous on small arthropods (Collingwood 1979).

Yemen

Sharaf et al. (2017) - This genus is recorded for the first time from Socotra; based on its distribution, this species has probably been introduced. This species was collected from moist soil and leaf litter under mango and date palm trees where the soil was rich in decaying organic material. It was also observed nesting under a stone next to a dragon blood tree. This species was also nesting directly in moist soil under a dead palm tree where organic materials are found. Another nest was found among old moist leaf sheaths surrounding the trunk base of a date palm tree.

Castes

Bolton and Fisher (2011) - As well as the usual workers and alate queens, it also produces ergatoid queens and dimorphic large and small ergatoid males, but never the usual alate male form. Yamauchi et al. (1996) studied reproductive behavior in a japanese population

Description

Worker

Bolton and Fisher (2011) - Measurements: HL 0.56–0.72, HW 0.46–0.60, HS 0.515–0.660, SL 0.35–0.48, PrW 0.33–0.43, WL 0.70–0.90, HFL 0.36–0.48, PeNL 0.14–0.20, PeH 0.30–0.39, PeNW 0.22–0.29, PeS 0.223–0.290 (60 measured). Indices: CI 79–87, SI 75–84, PeNI 63–74, LPeI 43–53, DPeI 140–165.

Eyes small but conspicuous, of 1–6 often poorly defined or partially fused ommatidia, located far forward on the side of the head. Impression that extends back along midline of head from the frontal lobes reaches at least the midlength of the vertex and usually further. Apex of scape, when laid straight back from its insertion, usually fails to reach or less commonly just touches the midpoint of the posterior margin in full-face view; SL/HL 0.62–0.70. Minute punctulate sculpture of cephalic dorsum extremely fine and superficial. Mesonotal-mesopleural suture absent. Metanotal groove deeply incised across dorsum of mesosoma; mesonotum with a well-defined posterior margin. Propodeal declivity rounds into the sides, without sharp marginations or carinae. In profile the anterior margination of the mesopleuron rounded to very bluntly angular behind base of anterior coxa; without a prominent sharp angle or tooth. Mesopleuron smooth and shining, at most with a few scattered punctures; usually with a small reticulate patch in the extreme posteroventral corner above the mesocoxa. Petiole in profile with the anterior and posterior faces of the node weakly convergent dorsally; node longer just above the anterior tubercle than at the dorsum. Sternite of petiole in profile a rounded lobe, without angles anteriorly or posteriorly. Maximum width of first gastral tergite in dorsal view less than the width of the second tergite at its midlength. Base of cinctus of second gastral tergite smooth and shining in dorsal view, without cross-ribs. Posttergite of second gastral segment, from posterior margin of cinctus to apex, much broader than long. Disc of second gastral tergite minutely punctulate, appearing weakly microreticulate in places. Full adult colour varies from dull brownish yellow to very dark brown or almost black. In general, workers at the bottom end of the size range given above tend to be lighter and the colour becomes darker with increasing size, but this is by no means an entirely consistent rule.

Queen

Fusca, pube adpressa cinereo-micans, ore, antennis pedibus et apice abdominis pallide rufis, oculis margini anteriori capitis proximis. - Long. 3 – 3 1/2 Mm.

Bolton and Fisher (2011) - True queens are alate, with much larger eyes (obviously >50 ommatidia) that have short setae projecting between the ommatidia, and have a full complement of flight sclerites on the mesosoma. Ergatoid queens are very worker-like but have larger eyes (usually 10 to about 20 ommatidia) and a developed mesonotal-mesopleural suture that is absent in the worker.

Male

Bolton and Fisher (2011) - Ergatoid males fall into major (larger, brown and with small eyes present) and minor (smaller, yellow and eyeless) categories (Yamauchi, et al. 1996) and are again very worker-like, especially in head structure, but have shorter scapes (SI 68–72), only 12-segmented antennae (as do workers, intercastes and queens), and of course fully developed but retractile male genitalia. Alate males have never been seen and it is probably now safe to say are never produced.
