Remarks. The drawings of the type-specimen deposited at NHM presented by Leech (1972: figs 189, 190), actually refer to the type of Goeldia obscura Keyserling, 1891 (Leech (1972: 103), penultimate paragraph and personal communication). However, this information was misinterpreted as if the specimen depicted was the first male of Goeldia obscura (Keyserling, 1878) since at that point, G. obscura Keyserling 1891 was considered a junior synonym of G. patellaris (Simon, 1892), see more under G. patellaris description. Regarding Goeldia patellaris, its syntypes are not conspecific with G. obscura Keyserling, 1891 and are removed from the synonymy.
The only specimen collected from the Brazilian state of Espírito Santo is the type specimen and there is no other record from this locality or nearby areas. Thus, we suspect that the type locality of this species could be wrong. Even though the type locality may be wrong, we make no changes but raise a red flag for future studies.
Etymology. The new name is an honor in memorium of Robin Leech, arachnologist and entomologist who contributed to the study of Titanoecidae spiders.
Diagnosis. Goeldia leechi nomen nov. differs from other species by the male palp with patellar apophysis posteriorly projected, longer than patella length and with a small terminal constriction near its apex (Figs 3B–C; 4A–B), tegular process narrow near its base and broad and slightly curved at the apex (Figs 3A–B; 4A–F); female epigynum with reduced and depressed median field, with posterior edge concave (Figs 3E; 5A); copulatory ducts long and slender, with base fully visible at the copulatory opening (Figs 3E–F; 5B–D) and two spermathecae with girth similar to copulatory ducts (Figs 3F; 5B–D).
