Taxonomic remark According to Huys (2009):
1) Sars (1911) proposed Leptomesochra for Mesochra macintoshi Scott & Scott, 1895, Normanella attenuata Scott A., 1896, Leptomesochra tenuicornis Sars, 1911, and Leptomesochra confluens Sars, 1911; but he did not fix the type species, rendering the genus name Leptomesochra unavailable.
2) Lang (1936) proposed the genus name Leptameira with Leptomesochra confluens as the type species, but did not include a diagnosis for Leptameira, rendering the genus name unavailable. Later, Nicholls (1939) added Leptameira attenuata Nicholls, 1939, and gave the diagnostic features to differentiate Leptameira, but he failed in fixing the type species, rendering the genus name unavailable one more time.
3) Lang (1944) relegated Leptameira to a junior subjective synonym of Leptomesochra, but the designation of Mesochra macintoshi as the type species of Leptomesochra was also invalid, rendering the genus name Leptomesochra unavailable again.
4) It was Vervoort (1964) who validly fixed Normanella attenuata Scott A., 1896 as the type species, and included Leptomesochra nasuta Sewell, 1940, Leptomesochra africana Kunz, 1951, Leptomesochra eulitoralis Noodt, 1952, Leptomseochra elongata Bozic, 1955, Leptomesochra pygmaea Vervoort, 1964 and Leptomesochra nichollsi Noodt, 1955, the latter is a substitute name of Leptomesochra attenuata (Nicholls, 1939), a secondary homonym of Leptomesochra attenuata (Scott A., 1896).
5) Lang (1965) revised the genus Leptomesochra and divided it into three genera:
- Praeleptomesochra Lang, 1965 (L. africana as the type species, plus Praeleptomesochra similis Lang, 1965, and Leptomesochra pygmaea),
- Leptomesochra Sars, 1911 (Mesochra macintoshi, Leptomesochra nasuta, Leptomesochra confluens, Leptomesochra infima, and Leptameira attenuata Nicholls, 1939),
- Interleptomesochra Lang, 1965 (L. tenicornis as the type species, plus Normanella attenuata Scott A., 1896, Leptomesochra tenuicornis, Leptomesochra elongata, Leptomesochra eulitoralis and Interleptomesochra reducta Lang, 1965)

Interleptomesochra Lang, 1965 became a junior subjective synonym of Leptomesochra Sars, 1911, because Sars (1911) concept of Leptomesochra and Lang's (1965) concept of Interleptomesochra contains Normanella attenuata Scot A., 1896, and the generic concept of Leptomesochra Sars, 1911 coincides with Lang's (1965) diagnosis of Interleoptomesochra.
Two other species were originally added to Interleptomesochra Lang, 1965, Interleptomesochra noodti Galhano, 1968, and Interleptomesochra boguensis Lindgren, 1975. Since Interleptomesochra Lang, 1965 is a junior synonym of Leptomesochra Sars, 1911, these two species became Leptomesochra noodti (Galhano, 1968) and Leptomesochra boguensis (Lindgren, 1975). Then, Leptomesochra (with Mesochra macintoshi, Leptomesochra nasuta, Leptomesochra confluens, Leptomesochra infima, and Leptameira attenuata Nicholls, 1939), became orphaned because its type species, Normanella attenuata Scott A., 1896, was left in Interleptomesochra.

Huys (2009) made available Lang's (1936) Leptameira with Leptomesochra confluens Sars, 1911 as the type species, and included Mesochra macintoshi Scott & Scott, 1895b = Leptameira macintoshi (Scott & Scott, 1895b) comb. nov., Leptomesochra confluens Sars, 1911c = Leptameira confluens (Sars, 1911c) comb. nov., Leptomesochra infima Monard, 1928 = Leptameira infima (Monard, 1928) comb. nov., Leptameira attenuata Nicholls, 1939a = Leptameira attenuata (Nicholls, 1939a) comb. nov.; Leptomesochra nasuta Sewell, 1940 = Leptameira nasuta (Sewell, 1940) comb. nov., Leptomesochra hirsuta Wiborg, 1964 = Leptameira hirsuta (Wiborg, 1964) comb. nov., Leptomesochra theodoridis Soyer, 1966 = Leptameira theodoridis (Soyer, 1966) comb. nov., Leptomesochra eremeensis Kornev & Chertoprud, 2008 = Leptameira eremeensis (Kornev & Chertoprud, 2008) comb. nov., and Leptomesochra kunzi Kornev & Chertoprud, 2008 = Leptameira kunzi (Kornev & Chertoprud, 2008) comb. nov.

Taxonomic remark According to Huys (2009):
1) Sars (1911) proposed Leptomesochra for Mesochra macintoshi Scott & Scott, 1895, Normanella attenuata Scott A., 1896, Leptomesochra tenuicornis Sars, 1911, and Leptomesochra confluens Sars, 1911; but he did not fix the type species, rendering the genus name Leptomesochra unavailable.
2) Lang (1936) proposed the genus name Leptameira with Leptomesochra confluens as the type species, but did not include a diagnosis for Leptameira, rendering the genus name unavailable.

Interleptomesochra Lang, 1965 became a junior subjective synonym of Leptomesochra Sars, 1911, because Sars (1911) concept of Leptomesochra and Lang's (1965) concept of Interleptomesochra contains Normanella attenuata Scot A., 1896, and the generic concept of Leptomesochra Sars, 1911 coincides with Lang's (1965) diagnosis of Interleoptomesochra.
