P. mendicula is an adaptable species. At La Selva, near Puerto Viejo, Costa Rica, Longino (1997) found a nest in the clay soil of a lawn surrounded by rainforest. Other sites include a second-growth forest and a rotten branch in a bamboo grove (Trinidad), and a rotten stick on the floor of terra firme rainforest (Brazil). On the Osa Peninsula of Costa Rica, Longino (1997) collected a worker from an extrafloral nectary of Passifolia pittieri. Winged queens have been found in nests from May to July. (Wilson 2003)

Description
DIAGNOSIS From Wilson (2003): A very small, reddish brown member of the tachigaliae group, which group is characterized by 11-segmented antennae, and distinguished within it as follows.
Major: occiput rugoreticulate, antennal scrobes, frontal triangle, and mid-clypeus smooth, and rest of dorsal head surface transversely carinulate; all of head and mesosoma foveolate and punctate; strong transverse ridge just breaks the surface of the pronotal profile in side view as a right-angle; posterior half of dorsal head profile in side view weakly concave; postpetiole from above trapezoidal.
Minor: all of head and mesosoma foveolate and opaque; carinulae absent mesad to eye; propodeal spines backward projecting.
MEASUREMENTS (mm) Syntype major: HW 0.60, HL 0.66, SL 0.32, EL 0.08, PW 0.38. Syntype minor: HW 0.34, HL 0.34, SL 0.26, EL 0.06, PW 0.24.
COLOR Major and minor: body concolorous medium reddish brown, appendages a contrasting yellowish brown.
Figure. Upper: syntype, major. Lower: syntype, minor. Scale bars = 1 mm.
Type Material
From Wilson (2003): PANAMA: Barro Coorado Island, col. William M. Wheeler. Museum of Comparative Zoology - as reported in Wilson (2003)
Etymology
L mendicula, little and beggarly, or poor, presumably alluding to the small size and reduction of antennal segmentation.
