SPECIES, AUTHORITY A. tenuis (Song & Cao) Kalgutkar & Jansonius 2000
LOCATION King George Island, Antarctica.
ORIG DESCRIPTION* Spores pyriform, one end broadly rounded, the other slightly narrowed, widest part in the middle; size of holotype 33 x 25 µm; spores monoporate, pore located at pointed end, 3-4 µm in diameter, and having weak pore ring, about 2 µm thick; spore wall about 1 µm in thickness, surface smooth; one side of surface with a roundish thinning area, about 12 µm in diameter, with light color; spore dark to black.
COMMENTS* Species distinguished from other known species of the genus Lacrimasporonites by a roundish thinning area. Monoporisporites koenigii Elsik is similar in general shape, but differs by its smaller pore (0.5 µm) and thick spore wall (1.5 µm).

Etymology: for the thinning spore wall.

K&J REMARKS Because the authors provided the etymology of the specific name as being a Latin adjective, the error in correct orthography of the Latin epithet in the text is here (in Kalgutkar and Jansonius 2000) corrected (ICBN, Art. 60.1). The feature for which the spore was named, Kalgutkar and Jansonius (2000) believe, was interpreted erroneously. To Kalgutkar and Jansonius (2000), the outline of the "thin" spot was not "roundish", but rather hexangular, and represented the reflection of the outline of a diaphragm in the condenser, which shows as a brighter (not thinner) spot on the large opaque expanse of the spore wall. Moreover, Kalgutkar and Jansonius (2000) interpret the outline of the spore itself to show subtle constrictions where septa might resist the compressionary forces of the rock matrix. If this spore indeed has some two (or three) septa, and a very large distal cell, it belongs in Anatolinites. Tentatively, that is where Kalgutkar and Jansonius (2000) transfer the species; its appearance does not fit in well with the bulk of the species now assigned to Monoporisporites.
