Leucauge argyrobapta
a longjawed orbweaver		The type for this species, Linyphia (Leucauge) argyrobapta White,1841, was based on a specimen collected by Charles Darwin (the only spider he's known to have documented!) during the voyage of the H.M.S. Beagle, which specimen was subsequently lost after publication of its description. A neotype was not established until 2010 when one based on specimens collected in the type locality was established. At that time, L. argyrobapta was declared a junior synonym of venusta, but in 2018 it was removed from that synonymy, and is again recognized as a separate species. These two species are grossly differentiated by geographic range (argyrobapta being typically more tropical and coastal, while venusta is more northern and found in temperate climes.) Although there may be some generalized marking difference, more precise determination requires microscopic examination of the genitalia. "Surprisingly," according to Ballesterosa and Hormiga, 2018,these are not sister species, as their "estimated age of divergence implies that the morphologies in this two species...have remained seemingly invariable for at least 10 million years. At this writing (2023) we (NCBP) are considering as argyrobapta those coastal specimens having a dorsolateral pair of orange-yellow colored spots above the spinnerets on the opisthosoma in addi............

Vaejovis carolinianus
Southern Unstriped Scorpion		One of 66 species in this genus, all of which are North or Central American (Sissom, 2000). Carolinianus is the sole species that occurs east of the Mississippi. According to Sissom (2000), this genus is not monophyletic, indicating that several new genera should be eventually described. Sissom includes carolinianus in the Mexicanus Species Group, which includes the type species of this genus (mexicanus) but also appears to be heterogeneous and thus likely to be split and given new genus names.A moderately large scorpion. The dorsal surface of the cephalothorax, abdomen, and tail are dark reddish-brown, with obscure yellowish mottling but no pale stripes. The two species of Centuroides that...Shelley (1994) stated that he typically finds this species associated with pine logs and stumps.
