A worker of this species was collected from a rainforest litter sample.

Identification

Williams and LaPolla (2016) - This species has deep and complete mesonotal and metanotal sutures, anteriorly-placed eyes, and macrosetae with thick setal bases all of which are characteristic of Nylanderia. Nylanderia flaviabdominis bears a strong morphological resemblance to Nylanderia emmae and has a similar distribution, but can be distinguished from N. emmae by its rectangular head shape with rounded posterolateral corners, dark orange-brown coloration, dark macrosetae, and rugoreticulation instead of longitudinal striations on the propodeum. Like Nylanderia emmae, this species was likely thought to be a Prenolepis because its elongate mesosoma appears to be constricted. Both of these species however do not have the depression in the dorsal surface of the mesonotum that is seen in Prenolepis species.

Biology

Zhu and Wang (2014) found this species was an important disperser of "Corydalis wilfordii and C. racemosa (Papaveraceae) seeds in a subtropical evergreen forest at the Jiugongshan mountain (Hubei Province, China). The seed size of C. wilfordii is larger than that of C. racemosa, while the elaiosome/seed mass ratio of C. wilfordii is greater than that of C. racemosa. Being the mutual ant dispersers of the two Corydalis taxa, Pristomyrmex pungens (=Pristomyrmex punctatus) (with mass recruitment mode, i.e. to recruit a large number of ants to remove seeds when one ant found seed) and Prenolepis sphingthorax (=Nylanderia flaviabdominis) (with simple cooperative recruitmen mode, i.e. to recruit 5-30 ants to remove seeds when one ant found seed) played a varied role in seed dispersal of two plants. Prenolepis sphingthorax carried all seeds of the C. wilfordii to nests, with the average dispersal distance of 0.45 m and the removal number of seeds per hour of 7.3. Both Pristomyrmex pungens and Prenolepis sphingthorax carried the all seeds of C. racemosa to the nests, with the average dispersal distance of 6.27 m and 6.65 m, and removal number of seeds per hour of 34.2 and 10.6 respectively. The results suggested that seed removal rate of ant with mass recruitment was higher than that of ant with simple cooperative recruitment. The seed dispersal distance and short-term seed fate differed between the two studied plants, depending on ant foraging strategies and behavior and seed characteristics."
