Neoponera coveri

From Mackay and Mackay (2010): The holotype was collected in a dead hollow twig hanging in the foliage.

Identification
From Mackay and Mackay (2010): Pachycondyla coveri is closely related to Pachycondyla oberthueri, but can be distinguished by the coriaceous and punctate mandible with a dull surface (mandible is shining in P. oberthueri). Additionally the apex of the petiole of P. coveri is rounded, especially posteriorly, whereas the apex is angulate posteriorly at the apex, nearly pointed in P. oberthueri. Pachycondyla coveri is similar to Pachycondyla carinulata, but can be separated by the weak punctures on the dorsum of the pronotum, which are coarse and form poorly defined transverse striae in P. carinulata. The highest point on the apex of the petiole of P. coveri is located posteriorly as in P. oberthueri, not at mid length as in P. carinulata.

The angulate medial clypeal border of P. coveri could cause confusion with Pachycondyla becculata, which has a similar clypeus. The two species are easily separated as P. becculata lacks the carina on the pronotal shoulder. Pachycondyla coveri lacks the strongly concave anterior border of the postpetiole of P. concava, which also has an angle in the middle of the anterior border of the clypeus.

Worker
The worker is a moderately small (total length 7 mm) black ant with reddish brown appendages, including most of the coxae. The mandible has approximately 11 teeth. The medial clypeal tooth or lobe is large and well developed and overhangs the remainder of the clypeus. The sides of the head are nearly parallel and posterior margin is slightly concave. The head length is 1.64 mm; the head width is 1.40 mm. The eye (maximum diameter 0.44 mm) is located approximately 1 diameter from the anterior margin of the head (side view). The malar carina is well developed and nearly reaches the eye. The scape (1.60 mm) extends about ⅓ of its length past the posterior lateral corner of the head. The pronotal shoulder is formed into a sharp carina, which overhangs the side of the pronotum. The promesonotal suture breaks the sculpturing on the dorsum of the mesosoma, but the metanotal suture is barely marked. The propodeal spiracle is slit-shaped. The lower ½ of the anterior face of the petiole is nearly vertical and bends posteriorly to form a sloping dorsal face with the remaining half, which meets the posterior face near the posterior edge of the petiole. The posterior face is convex and not concave near the apex. The subpetiolar process consists of small angle followed by a concave region and a gradually diminishing process posteriorly. The stridulatory file on the second pretergite is well developed, the arolia between the tarsal claws are poorly developed but present.

Erect hairs are present on the dorsal and ventral surfaces of the head, the mandibles, the shaft of the scape, the sides of the head, the posterior margin of the head, the dorsum of the mesosoma, dorsum of the petiole, on the angular process on the subpetiolar process and all surfaces of the gaster. The hairs on the tibiae are suberect. Appressed pubescence is present on the dorsum of the head, dorsum of the mesosoma and all surfaces of the gaster.

The mandibles are coriaceous with scattered punctures, the medial lobe of the clypeus has poorly defined longitudinal striolae, the dorsum of the head is completely punctate with the regions between the punctures being smooth and shining, the punctures on the dorsum of the mesosoma are fine and the regions between the punctures polished, as is the side of the pronotum; the mesopleuron and side of the propodeum are partially covered with poorly defined striae, but portions are smooth and glossy, the side, anterior face and posterior face of the petiole are mostly glossy. The gaster is smooth and glossy, the punctures on the dorsum of the postpetiole are very fine, those on the remainder of the second tergum are slightly coarser.

Etymology
This species is named in honor of our close friend Stefan Cover of the Museum of Comparative Zoology, in recognition for all he has done for us and for the field of Myrmecology. Stef also collected the holotype.
