Etymology
The species name refers to the Simian Mountain (Sìmiàn Shān), the type locality where this species was first collected.[1]
Diagnostic characteristics
Males of Oedothorax simianensis can be recognized by a unique combination of features in their reproductive anatomy. A small structure called the paracymbium, near the male reproductive organ, has a split or forked tip, unlike the simple hook shape seen in related species such as Oedothorax paludigena.[1]
Another key feature is that the protegulum, a flexible structure near the sperm-transferring organ, is also forked at its base, while in other species it remains single.[1]
Additionally, the embolus, the narrow tube that delivers sperm, is relatively short, about half the length of the radix, a supporting structure. In similar species, the embolus is nearly as long as the radix.[1]
These traits help distinguish Oedothorax simianensis from all other known species in the genus.
