{Paratrechina vividulaNylander's (1846a) description is at {original description}. Nylander (1856b) showed the antenna, in comparison with longicornis (as gracilescens), this is at {original description} Buckley's (1866) description of picea is at {original description} Forel's (1893g) description of antillana is at {original description} Wheeler's (1906e) description of kincaidi is at {original description} Forel's (1908c) description of docilis is at {original description} Emery (1910a: 130) gave an illustrated description, this is at {original description} Santschi's (1929d) description of australis is at {original description}


{Paratrechina vividula}Note - the original description by Nylander was of specimens from a colony in hothouses in Helsinki, so the type location is mis-leading. Forel's (1908b: 64) note on var mjobergi has - "differs from type by its flatter alitrunk (less convex), with the metanotal groove a little more accentuated It is also a much darker brown, chestnut on the head and gaster; from hothouses in Stockholm". Emery (1910a) had the colour as red-gold to brown-gold, the gaster darker

[The queen shown on Paratrechina natalensis is from South Africa appears to match all the details of P. vividula and extends the known distribution to that country and, thus, sub-Saharan Africa. The locale, however, presumably, has a Mediterranean type climate enabling a migrant species to become established.

LaPolla, Hawkes & Fisher (2011) state that vividula can be separated from by the number of erect hairs (they use macrosetae) on the antennal scape, claiming that vividula has less than 10 such erect hairs on each scape.  As shown below, that is not the case with workers from Egypt.  In all other details the Egypt specimens appear to match the vividula description. Lapolla et al., however, chose to illustrate their paper with a vividula specimen from the USA. The Egypt specimen quite clearly differs from those I show of P. jaegerskioleldi, and that also are from Egypt, together with sexuals, of which the male genitalia exactly match those they show (Figs 99 & 100).

Now (September 2015) I have workers from Iran (bottom) which also show numerous erect hairs on the scapes.
