Rasopone breviscapa

This species is only known from a single dealate queen.

Identification
From Mackay and Mackay (2010): The female of Pachycondyla breviscapa is very similar to that of Pachycondyla rupinicola, but can be easily separated by the short scape. The scape of the female of P. rupinicola extends well past the posterior lateral corner of the head. Pachycondyla breviscapa is much larger than the females of other members of the ferruginea species complex. The worker of P. breviscapa would be expected to be similar to those of P. rupinicola, but have shorter scapes than the female (based on the relative scape length of the females and workers of P. rupinicola), which would allow P. breviscapa to be easily recognized.

Distribution
This taxon was described from Bolivia.

Worker
No workers known for this species.

Queen
The female is a moderate sized (total length 12 mm) ferrugineous red specimen. The mandible has approximately 9 teeth alternating in size. Some of the teeth are tiny and poorly developed. The anterior medial border of the clypeus is concave with two lateral angles. The head length and width are 1.7 mm. The maximum eye diameter is 0.3 mm and the eye is located slightly less than one diameter from the anterior margin of the head. The ocelli are tiny (0.06 mm diameter). The scape (1.35 mm) nearly reaches the posterior lateral corner of the head. The propodeal  spiracle  is circular and  the posterior face of the propodeum is outlined by a poorly defined carina. The petiole is narrowed toward the apex, but has a definite dorsal face; the subpetiolar process has a posteriorly directed lobe. The anterior face of the postpetiole is nearly straight and meets the dorsal face at nearly a right angle. The stridulatory file on the second pretergite is absent.

Erect hairs are present on the mandibles, posterior margin and sides of the head, anterior margin of the clypeus, along the shaft of the scape, on the dorsum of the mesosoma, dorsum of the petiole, posterior edge of the subpetiolar process and all surfaces of the gaster. The hairs on the tibiae are sparse and suberect to erect. Appressed silver pubescence is present on all surfaces.

The mandibles are finely striate; the remainder of the surfaces is mostly finely punctate and dull, except for the gaster, which is punctate, but slightly shining.

Male
No males known for this species.
