Rem.:

According to Sewell (1949, p.141) the proportional lengths of the various segments of the body are: 581:91:79:67:49:61:24:12: 36 = 1000. Genital segment divided into two sub-equal lengths by a groove or joint.
According to Grygier & Ohtsuka (2008, p.492) the Scott's description is sufficient to recognize Monstrilla longipes as a member of the new genus Maemonstrilla on the basis of its body form, the spinulose-reticulate cuticle of the cephalothorax and free metasomal pedigers, and the form and setation of P5. A suture crosses the dorsum of the genital segment, as in most species of Maemonstrilla. The ovigerous spines were not described. it is possible that one of the newly described species of the M. hyottoko group descrbed by the authors (but not L. simplex) is synonymous with M. longipes, but this cannot be demostrated.
Records of supposed female Monstrilla longipes fom Nicobar Islands (Sewell, 1949) and the Singapore Strait (Wickstead, 1961) and record from Ghardaqa, Red Sea (Al-Kholy, 1963), must be considered unsubstantiated at the specific level, although the specimens invloved presumably do belong to the M. hyottoko
