Diagnosis

Males and females of E. globosus can be distinguished from those of other theridiosomatid species following the genus diagnosis (see above). For species diagnosis details, see Coddington (1986).

Redescription

Male (MACN-Ar 29093)

Total length 1.09. Prosoma: length 0.54, width 0.55, height 0.56. Sternum: length 0.31, width 0.34. Eye diameters and interdistances: AME 0.07, PME 0.08, AME–PME 0.07. Opisthosoma: length 0.68, width 0.72, height 0.80. Leg formula: 1243. Dorsal shield of prosoma dark olive-green laterally, olive-green centrally ( Fig. 59A–B View Fig ). Dorsum of ocular area dark olive-green ( Fig. 59A–B View Fig ). Sternum dark olive-green ( Fig. 59C View Fig ). Dorsum of opisthosoma whitish-olive-green ( Fig. 59A View Fig ). Epiandrium, booklung cover, tracheal spiracle, spinneret field and behind anal tubercle olive-green ( Fig. 59C View Fig ). Legs I–II darker than III–IV, femora and patella light olive-green, tibiae and metatarsi, tarsi brownish-orange ( Fig. 59A–C View Fig ). Palp: paracymbium hooked, paracymbial process with setae row, median apophysis sub-rectangular with median groove and retrolateral projection extending anteriorly, conductor retrolateral surface finger-printed covering embolic apophysis, embolus as thin lamina, tripartite embolic apophysis ( Fig. 59D–F View Fig ; Coddington 1986: figs 176–178, 188–191).

Records and biology

Epilineutes globosus is distributed from Mexico to Brazil ( World Spider Catalog 2025). Records in this study are limited to collections made at 1135 m a.s.l. in premontane rainforest from Reserva Forestal Fortuna ( Fig. 1 View Fig ). Males and females have been collected mostly at night by looking up, although some specimens were also collected at night by looking down and others during the day by looking down and cryptic techniques.
