CA69236CFF97FFCC0280816A4213BC2C.taxon	diagnosis	Diagnosis and discussion. This species is most easily recognized by its peculiar falcate mandibles, unique in described workers of Cerapachyinae. These are elongate, somewhat resembling the condition observed in Dorylus, with the narrow masticatory margin equipped with two (excluding apical) well visible teeth and meeting the long basal margin at an obtuse angle, resulting in a wide gap between mandibles and clypeal margin at closure (Fig. 13). Since only one specimen of this species was available for study, nothing can be said of individual variability and degree of worker polymorphism.	en	Borowiec, Marek L.

CA69236CFF91FFC10280829C453CB9B7.taxon	diagnosis	Diagnosis and discussion. This species shares most characters with C. sexspinus. C. eguchii can be fairly easily distinguished from it and all other species of the group by combination of color, sculpture and shape of subpetiolar process. The body is bicolored in C. eguchii, with head and mesosoma clearly darker than remaining of body. The lateral sides of mesosoma are sculptured with fine microreticulum, recognized easily at 50 X magnification. The subpetiolar process rather long, forming a claw-like structure, curved posteriorly, and with semi-translucent narrowing in form of oval fenestra situated in the middle of the process (Fig. 4). C. sexspinus seems to have the body always unicolored, yellowish. The lateral sides of mesosoma are also microreticulate, but much more finely, so that under 50 X magnification the surface appears matt with no individual lines of reticulation easily discernible. The subpetiolar process is shorter, not drawn into any spike, with ventral margin just evenly sloping towards the posterior end and a semi-translucent narrowing present along the ventral surface, except the anteriormost portion which is thick and opaque (Fig. 10). Katsuyuki Eguchi (pers. comm.) informs that this species is locally not uncommon in Vietnam, nesting in soil, with colonies found under stones, and recorded from the following habitats: well-developed lowland evergreen / semi-evergreen forest influenced by a relatively strong dry season (Colony # Eg 04 - VN- 748), and dwarf forest under a very dry climate (Eg 12 v 07 - 03).	en	Borowiec, Marek L.

CA69236CFF9CFFC30280841943C6BDCA.taxon	diagnosis	Diagnosis and discussion. This species is aberrant in many characters as compared with others belonging to the group and thus easy to recognize. It is the only member of the group having 11 - segmented antennae. The anterior margin of clypeus is conspicuously modified and drawn here into a semi-translucent lamella and laterally forming large, blunt teeth projecting over mandibles. Parafrontal ridges, however very low and reduced, can be seen in this species, as opposed to the others in this group. The petiole is also quite special in having the dorsal surface sloping evenly into posterior end, thus not having well differentiated perpendicular posterior face. Abdominal segment III is unique by being very small compared to the following one, with narrow and rounded anterior faces, as opposed to clearly differentiated, perpendicular portion of tergites and sternites observed in other species. The sculpture of the head and dorsal mesosoma is strong, composed of closely spaced, regular, and umbilicate foveae. The abdomen of this species is portrayed as fig. 18 in Bolton (1990).	en	Borowiec, Marek L.

CA69236CFF9EFFC4028083AB43EFB990.taxon	diagnosis	Diagnosis and discussion. This species can be distinguished from C. eguchii by differences in color, sculpture and shape of subpetiolar process. See diagnosis and discussion under eguchii for more details. Xu (2000) reports that this species constructs nests in soil with colonies ranging from 20 to 385 individuals, foraging probably in soil and under leaf litter. The habitats where this species has been found include seasonal rainforest, mountain rainforest, deciduous monsoon forest, and warm deciduous broad – leaved forest, ranging from 730 to 1280 m in elevation. In addition to material examined by the author from Mengla county, Xu (2000) reports this species from two other localities in Yunnan: Menghai and Jinghong counties. It is unknown whether specimens mentioned from Thailand (Jaitrong & Nabhitabhata 2005) represent this species.	en	Borowiec, Marek L.
