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............
