Rogeria procera

Nothing is known about the biology of this species.

Identification
Kugler (1994) - Most similar to but not quite like other species in the scandens species group. WL 1.28-1 .53mm. Eye very large. Propodeal spines long, not inclined. Postpetiolar node small, subconical; sternum inconspicuous and without a differentiated peduncle. Middorsum and posterior head with fine, nearly straight longitudinal rugae. Mesosoma and petiolar node with thick, vermiculate rugae. Erect hairs tapered; rarely any appressed or decumbent hairs on mesosoma dorsum, gaster, or legs. Scapes and extensor surfaces of legs with erect hairs and appressed to decumbent pilosity. Palpal formula, propodeal spiracle, metapleural lobes, petiole, pygidium, and sting apparatus as in scandens-group diagnosis.

Worker
Kugler (1994) - TL 4.5-5.4, HL 1.07-1.19, HW 0.91-1.08, SL 0.66-0.78, EL 0.19-0.23 (about 80-100 facets), PW 0.67-0.80, WL 1.28-1.53, SpL 0.26-0.32, PetL 0.60-0.73, PpetL 0.28-0.33mm, CI 0.85-0.91, OI 0.20-0.22, SI 0.70-0.75, PSI 0.18-0.23. N=7

Mandibles triangular with 6 teeth; basal larger than neighbor. Clypeal apron with shallow median notch. Nuchal grooves shallow, not visible in lateral view. Sting apparatus like that of inennis, but spiracular plate with more rounded anteroventral corner and gonostylus with separate proximal and distal patches of sensilla.

Laterodorsa of head longitudinally rugose-areolate; sides below eye smooth and shiny. Microsculpture vaguely microareolate on anterior laterodorsa; more effaced on rest of head, imparting a vaguely granular, shiny appearance between rugae. Promesonotum longitudinally vermiculate-rugose. Meso- and metapleura rugose. Interrugal spaces on mesosoma and petiole almost smooth. Postpetiolar node shiny with vague rugae and weak microsculpture.

Scapes and head dorsum with erect hair and much shorter appressed to decumbent pilosity. Mesosoma, legs, waist, and gaster with erect hairs, but rarely any decumbent or appressed hairs.

Mesosoma and waist black to dark brown; appendages and sometimes gaster lighter brown.
