Hypogastrura manubrialis (50904594528)

Description:

Description: Someone sent me some springtails to identify which they had found grazing on a church wall. My first thought was Hypogastrura viatica but I've spent two days banging my head against the chaetotaxy and they're not! They have 111 clavate tenant setae (c.f. H. viatica: 233; H. purpurescens: 232), so H. manubrialis is a possibility but frankly I'm unconvinced by the mucro, so they're going to remain as Hypogastrura spp. However, I'd welcome comments from anyone who is better with these than I am. UPDATE: This is Hypogastrura manubrialis. Date: 3 February 2021, 14:41. Source: Hypogastrura manubrialis. Author: AJC1.
