Anterhynchium abdominale (Illiger)

This species occurs in the Indian subcontinent, and several color phases are recognized in India. Within Sri Lanka it appears to be restricted to rather dry areas at low altitudes in the Dry Zone. Our limited observations suggest that this wasp nests in the ventilation shafts of the large termitaria of species of Odontotermes. The few localities where we collected it in Sri Lanka are as follows.

Mannar District: 0.8 km NE of Kokmotte Bungalow, Wilpattu National Park

Anuradhapura District: Hunawilagama

Trincomalee District: Trincomalee, China Bay

Amparai District: Lahugala Sanctuary

Puttalam District: Tabbowa

The elevations are 25–100 m, and the average annual rainfall is 1200–1750 mm.

NEST.—We observed abdominale during May and June 1976 near Kokmotte Bungalow, and in Lahugala Sanctuary. We saw several females of nominotypical abdominale, 13–17 mm long, entering ventilation shafts of Odontotermes sp. at both localities, and remaining inside for periods ranging from 1 to more than 10 minutes. We did not excavate nests, but Batra (1979) reared the dark color phase, abdominale bengalense (Saussure) from cells off the inner surface of ventilation shafts of Odontotermes obesus (Rambur) in Amritsar District, Punjab, India. She found that a nest consisted of 1 to 11 individual cells 36–79 cm below the top of the shaft. The cells were 19–20 mm long, 11–12 mm maximum width and were lined with a chestnut brown flexible material with embedded soil particles. I presume that the lining was a secretion applied by the larva in lieu of spinning a typical cocoon, a behavioral trait exhibited by the North American eumenid, Monobia quadridens (Linnaeus) (Krombein, 1967:51). Batra’s individual cells were capped by an earthen plug 5.5–6.0 mm wide and 4–10 mm long that connected the cell to the inside of the shaft. Her diapausing larvae began to pupate in mid-June and the first adult wasps emerged in about 24 days.

ASSOCIATE.—I saw a female chrysidid, Chrysis schioedtei Dahlbom, 11 mm long, alighting upon a shaft that had been entered by a female of abdominale; presumably it is parasitic upon the eumenid. Batra found a large parasitic wasp larva in a cocoon in one cell, and small dipterous puparia and remains of the caterpillar prey of the wasp in two other cells.

Anterhynchium abdominale

Anterhynchium abdominale is a species of potter wasp in the family Vespidae. It is native to India, Pakistan and Sri Lanka.[1]

Taxonomy

This wasp was first described in 1802 by the German entomologist and zoologist Johann Karl Wilhelm Illiger. There are two subspecies, A. a. abdominale and A. a. bengalensis. There are considerable differences in the colour patterns of the abdominal tergites of these subspecies, and further study is needed to determine their correct status as subspecies or full species. The potter wasps used to be considered a separate family, Eumenidae, but it is now considered to be a subfamily, Eumeninae, of the family Vespidae, the wasps.[2]

Ecology

Like most other potter wasps, Anterhynchium abdominale is a solitary species. The female excavates a nesting hole or uses a pre-existing cavity in which to nest. A single egg is laid in the nest, which is then provisioned by the female who forages for caterpillars and other insects, stinging them to paralyse them. The nest is then sealed, and the developing wasp larva feeds on the supplies, which are kept fresh by being alive.[3] In one instance in Punjab, an old termite mound of Odontotermes obesus was used for nesting, with several individual wasp cells scattered across the surface. Egg-laying took place in January and the larvae pupated in June, emerging as adults in July and August.[4]
