This species is only known from the type locality, Tasek Merimbun (Brunei, Tutong).

Identification

In the worker, cranium subtrapezoidal in fullface view; dorsum of mesosoma longitudinally costate; abdominal tergite III with costae which are transversely arched around center of posterior margin in dorsal view; abdominal sternite III longitudinally costate; cinctus of abdominal segment IV smooth without any costae; abdominal tergite and sternites IV smooth with sparse hair-bearing foveae.

Chrysapace merimbunensis is relatively similar to Chrysapace sauteri and its sibling species Chrysapace costatus by sharing the following characteristics of the worker:

  • dorsum of mesosoma, petiolar tergite, and abdominal sternite III longitudinally costate
  • abdominal tergite IV–VI lacks any costation

However, the worker of the former is easily distinguished from those of the latter two species by subtrapezoidal shape of cranium in full-face view, non-costate posterodorsal face of helcium, abdominal tergite III with costae which are transversely arched around center of posterior margin in dorsal view, and non-costate cinctus of abdominal segment IV.
