Aposphragisma helvetiorum Thoma, 2014: 36-44 Diagnosis. The genus Aposphragisma most resembles the genera Gamasomorpha Karsch, 1881 and Xestaspis Simon, 1884 ( Thoma et al. 2014 ) but they can be differentiated based on the combination of the following characters: hard-bodied spiders; sternum with microsculpture; dorsal and ventral abdominal scuta not fused; labium strongly incised; legs without spines. Furthermore, males are distinguished by their palpal bulb bearing an apical embolus closely associated with a laminar conductor ( Thoma et al. 2014 ). Distribution. Borneo, Indonesia (Sumatra), Malaysia, Singapore and Vietnam.
