An emended description of Sminthurinus lawrencei Gisin 1963, with notes on the identification of black Sminthurinus species van Bezouw, Roel F. H. M. McCulloch, James Janssens, Frans Berg, Matty P. Soil Organisms 2022 2022-12-01 94 3 127 138 4XX6Q [920,1237,503,531] Collembola Katiannidae Sminthurinus Animalia Symphypleona 7 134 Arthropoda species lawrencei  The use of the colouration and shape of the inter-ocular vesicles is a trait that was first used since 2015 by the third author, a character to distinguish between the dark Sminthurinus-specieson digital images. By examining the collection material, this character is found to reliably separate the otherwise uniformly black  S. lawrenceifrom  S. nigerand  S. concolor. In  S. lawrencei, these white inter-ocular vesicles are small, roundish with three teeth pointing inwards in an adult specimen. This inter-ocular vesicle does not advance beyond ocellus C and the distance between the left and right inter-ocular vesicle is more than twice that of the inter-ocular vesicle diameter ( Fig. 5A). In  S. niger, this white inter-ocular vesicle circumvents most of the upper and posterior sides of the ocular fields, creating a large crescent shape in full-grown adults ( Fig. 5B). In  S. concolor, these inter-ocular vesicles are much larger than in  S. lawrenceiand are not crescent shaped. The distance between these inter-ocular vesicles is less than twice that of the inter-ocular vesicle diameter and features a single, large anterior indentation ( Fig. 5C). The listing in table 1 is not exhaustive for images from public images due to the large number of records available, which are nearly always misidentified  S. niger. However, several of such photographs were taken from Franceand Canada, from which S. lawrenceiwas not previously recorded and these are thus included in the list ( Table 1, Fig. 4).
