Nothing is known about the biology of Carebara longiceps.

Identification

Fernández (2004) - A member of the Carebara lignata species complex. This species can be readily differentiated by the frontal lobe configuration, the propodeal configuration in side view, and the small subpetiolar spine. Moreover, the bullae of metapleural gland look bigger than in other species. Knowledge of males in this group is limited, but the head striation is remarkable.

Distribution

This species appears to have the most southerly distribution of the lignata complex species.

Latitudinal Distribution Pattern

Latitudinal Range: -31.657° to -31.657°.

Description

Worker

Fernández (2004) - Lectotype: HW 0.25; HL 0.38; SL 0.18; PW 0.15; WL 0.31; GL 0.33; TL 1.18; CI 66; SI 72.

Head slightly longer than wide. Posterior border concave, lateral sides faintly concave. Mandibles apparently with 4 teeth (lectotype with mandibles closed, difficult to see clearly). Median portion of clypeus slightly concave. Scapes fail to reach the vertexal border in 1/3 of the head length. Frontal lobes rounded. In side view, alitrunk flat, slightly interrupted by the shallow metanotal groove. Sides dorsal and posterior of propodeum nearly at 90°. Propodeal spiracle relatively small, circular, high and near the propodeal margin. Bullae of metapleural gland large. Propodeal lobes reduced to narrow lamellae that more or less reach the propodeal spiracle. Petiole with short peduncle, evenly continous with the dorsal rounded node; petiolar spiracle nearer to propodeal lobes. Subpetiolar process produced as small spine directed anteriorly. Postpetiole dorsally concave, lower than petiole. Anterior margin of first tergum slightly concave in dorsal view. Body smooth and shining. Vestiture as in Carebara elongata except by: two moderate hairs near each occipital corner, several in anterior portion of pronotum. Body light yellow.

Male

Fernández (2004) - HW (including eyes) 0.75; HL 0.50; EL 0.13; SL 0.10; PW 0.69; WL 1.10; GL 1.38; TL 3.58; CI 150; SI 13.

Mandibles with the masticatory margin more or less straight, with four teeth nearly similar in size. Clypeus markedly bulging, anterior margin feebly concave. Scapes very short. Promesonotum dorsally with three longitudinal lines, the central longer. Marginal cell closed. Petiole ventrally with several irregular longitudinal carinae. Postpetiole broadly attached to the gaster. Genitalia with two big falcate parameres. Body slightly shining with moderate pilosity, especially on head. Head anteriorly with strong longitudinal striation, posteriorly oblique striation. Longitudinal striation in the central area of pronotal dorsum. Body dark brown, appendages lighter.

Type Material

Fernández (2004) - Lectotype worker (here designated): ARGENTINA. Alta Gracia, 1 worker, la Granja, Sierras de Córdoba, 1924, C. Bruch leg., Museu de Zoologia da Universidade de Sao Paulo. 1 male, paralectotype (here designated). Same data as worker (MZSP).
