Biology:

Longino, 1 Mar 2014: I now consider this to be a widespread, somewhat weedy species. In Costa Rica it inhabits both lowland rainforest of the Atlantic slope and lowland dry forest in Guanacaste. At La Selva Biological Station, workers are fairly common in Winkler samples. Nests have been found in small rotten sticks on the ground. At Santa Rosa National Park, I collected a nest in a small soft stick on the ground in Quercus oleoides forest. On the Barva transect it decreases quickly with elevation, and is rare by 500m. At the Osa Biodiversity Center on the Osa Peninsula, in a survey of litter ants, it was rare in 2008, a relatively wet year. The same plot was resurveyed in 2010, a drier year, and S. azteca had become one of the most common species.

Identification:

Size small; color yellow with darker gaster; anterior clypeal margin without projecting teeth; compound eye circular, dark, composed of about 5 fused ommatidia; sparse long hairs projecting from sides of head and vertex margin; mesosoma short and compact; postpetiole lacking anteroventral process.

Comments:

Longino, 1 Mar 2014: Longino morphospecies JTL008 in earlier works.

1. Solenopsis aztecaHNS, n. sp.

(No. 10 d, 10 e, et 10 i), [[ worker ]].

[[ worker ]]. L. 1,2 a 1,4 mill. Plus robuste que la S. corticalisHNS. Mandibules courtes, a bord terminal nullement oblique, large, arme de 4 larges dents peu pointues. Les mandibules sont lisses, luisantes, avec quelques points enfonces. Tete en rectangle allonge. Yeux relativement developpes, plats, composes d'environ 7 facettes et situes un peu en avant du tiers anterieur des cotes de la tete. Epistome fortement bicarene, a peine avance, sans dents a son bord anterieur; les carenes assez distantes. Antennes tres courtes. Le scape est epais et n'atteint que les 3 / 5 de la distance de sa base au bord posterieur de la tete. Les antennes ont 10 articles; les articles 3 a 5 du funicule sont au moins trois fois aussi larges que longs; le dernier article est tres grand, aussi long que les 7 prece- dents reunis. Thorax assez large et assez court, ' sans trace de suture pro-mesonotale. Une forte incisure entre le mesonotum et le metanotum. Ce dernier mediocrement convexe, sans aucune limite entre la face basale et la face declive. Cependant, d'apres le profil de la courbe, la face declive serait la plus longue. Premier article du pedicule avec un petiole plus court que le n oe ud et une convexite inferieure comprimee et translucide, sans dent dessous. Le n oe ud est situe a l'extremite posterieure du 1 er article, large et arrondi en haut, bien plus haut quo le 2 me article, plus large que long. Second article un peu incline en avant, un peu plus large que long. Abdomen tronque devant. Pattes courtes.

Tres lisse et tres luisante. Quelques courtes stries devant les joues. Ponctuation piligera faible et eparse, meme sur les joues.

Une pilosite dressee, jaunatre, fine, de longueur mediocre, egale- ment et mediocrement repandue sur le corps, les pattes (y compris les tibias) et les scapes. Pubescence a peu pres nulle.

D'un brun jaunatre sale. Une large bande d'un brun noiratre au milieu de l'abdomen. Pattes, antennes et mandibules d'un jaune testace plus ou moins pale (mandibules plus foncees).

Malheureusement la [[ queen ]] n'a pas ete trouvee. Si Emery n'ecrivait pas clypeo acide bidentata je croirais que c'est sa Solenopsis brevicornisHNS. Peut-etre n'en est-ce qu'une race. La S. brevicornisHNS vient du sud du Bresil.

(10 d). Various situations. Not noted.

(10 e). Petit Bordelle Valley, 1600 ft. Nov. 13 th. Open place. A small nest in rotten wood. No female could be found.

(l 0 i). Richmond Valley, thick forest, 1100 ft. Dec. 29 th. Under decaying leaves, & c. (workers).
