Camponotus anatolicus

C. anatolicus is only known from a small area in the Antalya and Mugla region of Anatolia, Turkey, between 282 m and 886 m altitude. It was collected from the side of a brook in a woodland area with Pinus brutia, Quercus coccifera, and mixed forest (Quercus spp. and Pinus brutia) habitats.

Identification
A member of the Camponotus lateralis species group. C. anatolicus is distinguished from all of the C. lateralis group species except for Camponotus staryi by the deep metanotal groove and yellowish red to reddish brown first gaster segment that is paler than the rest of the gaster segments. C. anatolicus is similar to Camponotus staryi due to the deep metanotal groove and reddish brown first gaster segment. We compared C. anatolicus with the holotype of C. staryi, which is deposited in the MIZ PAS Museum, and the new species can be differentiated from the latter by the following in minor workers: the propodeal dorsum, which is lower than the mesonotum, a thicker and almost nodiform petiole, dense appressed pilosity on the head and scape, abundant, subdecumbent and erect hairs on the dorsum of propodeum; and in major workers: shallower metanotal groove, much longer propodeal dorsum that is transversely convex or flat, and covered by abundant erect hairs, head darker than the mesosoma, abundant erect hairs on the genae and erect hairs on the lateral sides of the head and occipital corners, and dense appressed pilosity on the scape.

Seifert (2019): The character combinations to identify this species can be derived from the key, Tab. 2 and the z-stacks. The dorsal propodeal plane is in dorsal view trapezoid – i.e., in posterior part much wider than anteriorly. The mesosoma is more hairy: the bilateral sum of setae on mesonotum and propodeum dorsal of spiracle is 13-27. The metanotal depression is very deep. Head, scape, mesosoma and petiole reddish to reddish brown; mesosoma, petiole, legs reddish to reddish brown; the first gaster segment often reddish to reddish-brown, the rest of gaster blackish.

Seifert (2019): Investigated were five paratype workers from the holotype nest, stored in SMN Görlitz and labeled ‘TUR: 36.4635°N 30.3339°E Altinyaka-Village, 551 m leg. C.Karaman 2007.06.06 –7/0888b’ and ‘Paratypes Camponotus anatolicus Karaman & Aktac 2013’. Note that the original description gives a wrong geographic latitude and longitude. These data are corrected here according to a personal communication with C. Karaman in 2018.
