Prenolepis guatemalensis antillana

Distribution
This taxon was described from Antilles. It is also found in Dominican Republic, Bahamas and Grenada.

Biology
Wheeler (1905) reported: This form is common and widely distributed on Andros and New Providence (Bahamas). It nests under stones and logs in rather moist places. Males and winged females were found during May and June (1904).

St Vincent
The opening text of the source paper (Forel 1893) for the following Hypoponera foeda collection records, by H. H. Smith, states "These notes are given in full, as it is thought that the precise localities in which the species were met with may be of interest to local naturalists."

(54). Common locally, especially in the forest. The communities consist of several hundred individuals. The formicarium is generally in rotten wood, sometimes under a stone, and I have found no trace of external galleries; generally there are several small chambers connected irregularly by short passages. All the forms are quite active. N.B.—More than one species may be included here, but I have not attempted to separate very closely allied forms.

(54a). Morne a Garou; forest,1500 ft. Nov. 1st. Under the bark of a damp rotten log. The formicarium, so far as I traced it, occupied an irregular space about four inches square. The winged ants were numerous.

(54b). Wallilobo Valley (leeward), Nov. 8th. Dry forest, hill-side, 800 ft. Small colony under a stone.

(54c). Morne a Garou; forest, 1500 ft. Oct. 27th. A small nest in rotten wood.

(54d). Wallilobo Valley, Nov. 8th. Damp forest. A nest of several chambers in a rotten stick

(54e). Bowwood Valley, near Kingstown. Second growth; 800 ft. Oct. 15th. Beaten from foliage.

(54f). Various situations.

(54g). Mountain forest, 3000 ft. March. Found in moss.

(54h). Richmond Valley, 800 ft. Cacao orchard. Sept. Formicarium in rotting leaves.

(54i). Upper Richmond Valley, 1500 ft. Nov. 27th. Forest near stream. Workers found scattered under sod on rocks or beaten from foliage.

(54j). Same locality as No. 54i. Nov. 27th. Forest near the stream. A small nest in and under a log.

(54k). Hermitage Estate, Cumberland Valley, 1000 ft. Damp forest. Formicarium in and under a log on the ground. Some of the galleries were walled in by a substance made of wood-fibre. Several hundred ants, with many winged males and females. Dec 2nd.

(54l). Richmond Valley; thick forest, 1100 ft. Worker found in decaying leaves. Males, doubtfully referred to this species, on freshly-cut wood Dec. 29th.

(54m). Same locality as No 54l. Jan. 18th. Under stone near stream.

(58). Apparently distinct from Nos. 19 and 54. I have found only a few specimens in thickets near the coast, under stones and rubbish, or on foliage; and I have not observed the nest.

(58a). Leeward side; at various points near the coast, thickets, or open land. Under stones and rubbish, or beaten from foliage. Aug.-Nov.

Worker
L. 2, 1 a 2, 5 mill. Elle ne se distingue de la guatemalensis i. sp., que par sa couleur plus foncee, d'un brun jaunatre sale, avec les antennes testacees, sa. taille un peu plus graude (la guatemalensis n'a que 2, 0 mill.), son epistome un peu moins voute et surtout, par son metanotum bien plus bas, plus aplati, plus allonge, formant une voute tres faible, tandis qu'il est assez fortemeut voute chez la guatemalensis i. sp.; chez les deux formes, la face basale est beaucoup plus courte que la face declive. La pilosite est aussi un peu plus pointue. Chez l’antillana, comme chez 1a guatemalensis i. sp., le bord anterieur de l’epistome est echancre au milieu et le scape depasse le bord posterieur de la tete des 2/3 de sa longueur. Chez l’antillana, le mesonotum est aussi long que le pronotum, chez la guatemalensis i. sp., sensiblement plus court.

Elle se distingue de la P. fulva par sa taille beaucoup plus petite et par son metanotum plus allonge et bien moins voute, ainsi que par sa pubescence plus faible.

Queen
L. 4, 8 mill. Plus grande que la guatemalensis i. sp. qui n'a que 3, 8 a 4 mill. Les ailes sont assez fortement enfumees de brun plus fonce que chez la guatemalensis i. sp. et la fulva, don’t elle est du reste fort difficile a distinguer.

Male
L. 2, 2 a 2, 4 mill. Metanotum allonge et subhorizontal, au moins aussi long que le mesonotum (sans l’ecusson). Valvules genitales exterieures pales (jaunstres), en triangle isocele presque equilateral, plus larges a leur base et plus pointues a l'extremite que chez la P. fulva. Valvules moyennes comme chez la P.fulva, maia plus cour        us massives; le proiongelllent externe n'est pas courbe. Du reste semblable au les males de toutes les formes voisines.
