The side edges of the pro- and mesonotum are covered with bumps or short conical spines.

These are situated on two barely recognizable crests running along the middle of the abdomen, which only merge into one in the area of the last abdominal segment.

The upper portion of the secondary ovipositor, the epiproct, is bifurcated at the apex with a fairly deep triangular incision.

In addition, in the females of Haaniella parva muiengae, the anterior, mesal, and posteromedial mesonatal spines are merely blunt tubercles.

The nominate subspecies occurs in the Indonesian provinces of Aceh and North Sumatra, making it sympatric and partly syntopic with Haaniella gintingi.

[2][3] The subspecies Haaniella parva muiengae has only been collected from gardens of Kedah Village near Mount Angkasan in Aceh Province.

[2][3] Klaus Günther described Haaniella parva using two males, then considered syntypes, which Dr. Volz have been collected from the Kwalu River in north-eastern Sumatra.

Of these, the specimen deposited in the State Museum of Zoology, Dresden was later selected as the lectotype.

According to Günther, the specimen that remained in the Zoological Museum Hamburg thus becomes a paralectotype, but various authors could not find it there.

It is named after Choo Mui Eng, who, among others, accompanied Seow-Choen on his photo trip to the gardens of Kedah Village, where the subspecies was found.

Three other paratypes can be found in the Lee Kong Chian Natural History Museum at the National University of Singapore.
