Figure 6 in Are invasive hymenopteran species replacing native mud dauber wasp-associated taxa on the Seychelles Archipelago?
Figure 6. Change of hymenopteran assemblage associated with nests of the mud dauber wasp Sceliphron fuscum (Sphecidae) in Seychelles (Mahé and Praslin) from the 1930s to 2016 (Vesey-Fitzgerald 1950; this study). The differences in frequencies of native and invasive taxa between the two periods are significant (χ2 = 4.055; df = 1; p = 0.044).

Figure 2. Examples of mud dauber wasps Sceliphron fuscum (Sphecidae) nest aggregations in Seychelles. (A) Mahé: under a rocky shelter. The blue arrow shows a female of Nephilingis livida (Vinson, 1863) (Araneae: Araneidae), a large spider species, whose webs are often accompanying massive conglomerations of mud dauber and potter wasp nests on the island. (B) Praslin: on the ceiling of a crumbling house. The red arrows show Megachile (Callomegachile) disjuncta (Megachilidae) females constructing their cells inside the nests of Sceliphron fuscum (note black, wax-like substance around entrances – a diagnostic feature of mud dauber wasp cells colonized by this bee species). (C) Silhouette: under a leaf of Coco De Mer Palm Lodoicea maldivica. (Photos: Ivan N. Bolotov [A, C] and Yulia Kolosova [B]).
Data from: A signature of dynamic biogeography: enclaves indicate past species replacement
Understanding how species have replaced each other in the past is important to predicting future species turnover. While past species replacement is difficult to detect after the fact, the process may be inferred from present-day distribution patterns. Species with abutting ranges sometimes show a characteristic distribution pattern, where a section of one species range is enveloped by that of the other. Such an enclave could indicate past species replacement: when a species is partly supplanted by a competitor, but a population endures locally while the invading species moves around and past it, an enclave forms. If the two species hybridize and backcross, the receding species is predicted to leave genetic traces within the expanding one under a scenario of species replacement. By screening dozens of genes in hybridizing crested newts, we uncover genetic remnants of the ancestral species, now inhabiting an enclave, in the range of the surrounding invading species. This independent genetic evidence supports the past distribution dynamics we predicted from the enclave. We suggest that enclaves provide a valuable tool in understanding historical species replacement, which is important because a major conservation concern arising from anthropogenic climate change is increased species replacement in the future.

Distribution. Poorly known, NC Colombia in the E of Boyaca Department, E to the highlands of Meta to at least 1500 m above sea level. It is unclear if this species occupies an enclave within the range of the Lemurine Night Monkey (A. lemurinus) or if it replaces it in the NE part ofits distribution. in Aotidae
