Taxonomic Remarks
Cheliplanilla sp.2 is comparable to C. caudata and C. karlingi, as these are the only species of Cheliplanilla possessing a stylet within the male copulatory bulb. However, in Cheliplanilla sp.2, the cirrus also bears triangular spines, which are absent in the other two species. The stylet of Cheliplanilla sp.2 (49 µm) is longer than that of C. caudata (30 µm) but similar in length to that of C. karlingi (49–50 µm). Nevertheless, the stylet of C. karlingi is curved, whereas that of Cheliplanilla sp.2 is almost straight.

Description of Material
Species of Cheliplanilla with proboscis hooks measuring 22 µm in length. Each hook bears two pairs of 2-µm-long denticles, one pair located at midlength and the other subdistally. The ejaculatory cirrus is armed with a 49-µm-long stylet (n = 1) and about eight triangular spines, measuring 3–4 µm in length (x¯ = 4 µm; n = 6).
