Diagnosis. The following combination of characters will separate the genus Olecryptotendipes Zorina from other members of the Harnischia complex:
Male: frontal tubercles absent; thorax and legs with or without spots; AR 1.13–2.24; acrostichals present, sometimes absent; squama with 0–5 setae; hypopygium with Y-type band, rarely separated medially; posterior part of tergite IX elongated with setae, sometimes with caudolateral shoulders; superior volsella with sclerotised part and membranous ridge, with 1–2 dorsal and 1 ventral setae, microtrichia absent or present; inferior volsella absent or reduced; gonostylus curved medially or in distal third.
Pupa with well developed frontal tubercles; frontal setae present or reduced to short rod-shaped outgrowths apically serrated; thoracic horn plumose; hook row widely interrupted medially; pedes spurii B present on segment I anteriorly; pedes spurii B absent on tergite II; sternites IV with pedes spurii A; tergites II–V with rectangular patches of shagreen or tergites II–VI or I–VI a median longitudinal band of spines; posterolateral comb or spur absent.
Larval body consisting of 20 apparent segments; anterior parapods with large claws; posterior parapods thin and elongated; antenna with 6 segments; pecten epipharyngis a simple scale with median notch apically or a triangular serrated scale or consists of 3 scales, median one slightly longer than lateral ones; premandible with 2 apical and 1–2 teeth in base, brush absent; mandible with sickle-shaped dorsal tooth, apical tooth and 2–3 inner teeth; seta interna present (with 4–6 simple branches) or absent; mentum with pale triangular median tooth and 6–7 pairs of yellowish brown lateral teeth or 2 median teeth and 5 pairs lateral teeth.
