Many species of Ptilomerinae are only known from apterous morphs; macropterous forms are rare and often dealate
(Chen et al.
In fact, this species appeared to be much more abundant than the previous year and multiple colonies with dealate
queens were discovered nesting under the bark of numerous palms.
The presence and number of ant dealate
females, alate females, males, workers, cocoons, and larvae, as well as the presence of any adult myrmecophile (especially eucharitid parasitoids), were recorded.
tuberculatum collected from the whole Soconusco region over 16 yr, only 3 were digynous and one contained 4 non-functional, mermithised dealate females (Lachaud, unpublished data).
The presence or absence of alate and dealate females in each nest was noted, as well as the number of males, workers, cocoons (pupae), larvae, and the presence of eggs.
From the 9 nests collected, 6 had only workers and brood, and only 3 contained dealate females: one with 1 dealate female, 1 with 2 dealate females and 1 with at least 7 dealate females and several alate females at the moment of collection.
A new species of ant, Solenopsis enigmatica, is described from 2 dealate queens and 3 workers collected from nests of Pheidole antillana Forel in rainforest on the island of Dominica, West Indies.
phoretica, was described, based on a single dealate queen found clinging to the petiole of a queen of Pheidole dentata Mayr (Davis & Deyrup 2006).
We have designated a dealate queen as the holotype because of the apparent close relationship between this species and S.
After flying, the alates shed their wings and associate as pairs of female and male dealates.
brevis and congenus alates is followed by negative phototaxis of the dealates (Wilkinson 1962; Minnick 1973), although no data have been produced to confirm this observation.
The second hypothesis tested was that dealates search for darker areas on the substrate to colonize.
