Taxonomy. The genus Dilobocondyla is assigned to the tribe Formicoxenini (Bolton 1994, 2003). A key to the described species was given by Wheeler (1924). Workers of Vietnamese species have the following features.
Worker monomorphic; head in full-face view subrectangular; preoccipital carina distinct laterally; posterolateral corner of head with a small acute angle or denticle exterior to preoccipital carina; frontal carina distinct; antennal scrobe shallow but distinct; median portion of clypeus broadly inserted between frontal lobes; anterior clypeal margin weakly convex and with a weak emargination at midpoint; median clypeal seta, if present, indistinct; mandible triangular, with 6 teeth on masticatory margin; antenna 12-segmented, with conspicuous 3-segmented club; eye relatively large; promesonotum in lateral view hardly or weakly raised; promesonotal suture absent dorsally; metanotal groove weakly impressed dorsally; propodeum in lateral view weakly swollen posterodorsad, unarmed; propodeal lobe well developed; femora strongly and abruptly incrassate in distal two thirds; petiole elongate, cylindrical, slightly arcuate in lateral view; subpetiolar process distinct, tooth-like, located anteroventrally near articulation with mesosoma; postpetiole in lateral view with acute anteroventral angle; gaster short, oval in dorsal view.
The worker of Dilobocondyla is easily distinguished from that of other myrmicine genera known from Vietnam by posterolateral corner of head with a small acute angle or denticle exterior to preoccipital carina, propodeum unarmed, femora strongly and abruptly incrassate, and petiole elongate and sylindrical.
Vietnamese species. One species has been described from Vietnam: fouqueti Santschi (type locality: Ha Noi). Two additional species have been recognized by us from Vietnam: sp. eg-1 (Da Lat); sp. eg-2 (Tay Ye n Tu).
Bionomics. We have rarely encountered foraging workers of Dilobocondyla on leaves in undergrowth of natural and man-made forests.
Dilobocondyla is a genus of ants in the subfamily Myrmicinae.[2] The genus is distributed in the Oriental and Australasian realms. It seems to be rare, with most species known only from single specimens.[3]

Dilobocondyla (лат.) — род мелких муравьёв (Formicidae) из подсемейства Myrmicinae.
Мелкие муравьи (длина около 4—5 мм) коричневого цвета; у некоторых видов брюшко или грудка более светлые, рыжеватые. Усики самок и рабочих 12-члениковые (у самцов 13-члениковые), булава 3-члениковая. Формула щупиков (нижнечелюстные и нижнегубные): 4,3 или 3,3. Жвалы бороздчатые, с 6 зубцами на жевательном крае. Голова массивная, задние боковые края угловатые. Пронотум с боковыми зубцами на плечевых выступах. Заднегрудка невооружённая, без проподеальных зубцов или шипиков. Стебелёк между грудкой и брюшком состоит из двух члеников: петиолюса и постпетиолюса (последний четко отделен от брюшка), жало развито, куколки голые (без кокона)[2].
Около 20 видов. Род относится к трибе Formicoxenini. Ранее (до 1994 года) их относили к трибе Myrmecinini (Wheeler, W.M. 1922; Bolton, 1994, 1995)[3][4][5][6].
