“…Semispecies are groups of organisms in the “grey zone” of speciation, which have completed some of the necessary steps towards full species separation, but not all of them. Semispecies have often been used to classify island populations (as a synonym of allospecies), and the rare examples in arachnology also applied the concept strictly to allopatric populations (Kraus 2000); however, such a narrow interpretation is not necessary, and in groups with a more mature taxonomy (especially birds and butterflies) locally sympatric (as well as parapatric) groups of semispecies are identified with some regularity (e.g., Helbig et al 2002; Smith et al 2010), albeit not without lively debate regarding individual cases (e.g., Pfander 2011; Vane-Wright 2020).…”

The recent accumulation of increasingly densely sampled phylogenetic analyses of spiders has greatly advanced our understanding of evolutionary relationships within this group. Here, this diverse literature is reviewed and combined with earlier morphological analyses in an attempt to reconstruct the first fully resolved phylogeny for the spider fauna of the British Isles. The resulting tree highlights parts of the group where data are still too limited for a confident assessment of relationships, proposes a number of deviations from previously suggested phylogenetic hypotheses, and can serve as a framework for evolutionary and ecological interpretations of the biology of British spiders, as well as a starting point for future studies on a larger geographical scale.

“…Over much of Africa, different colour forms are present in different regions of the continent (illustrations and distributions in Smith et al, 2019) as essentially monomorphic populations, though minor variation occurs, and rare vagrants from other ranges are found. The all-orange forms were called dorippus in Smith et al, 2019 but are now known as klugii (Vane-Wright, 2020). Within the polymorphic contact zone, various intermediates result from incomplete dominance and recombination as described by Smith et al (2019).…”

Morph frequencies, sex ratios and infections in Danaus chrysippus populations in Rwanda

et al. 2022

The African Queen butterfly (Danaus chrysippus) is noted for its colour pattern polymorphism despite its aposematic and chemically defended lifestyle and for its infection with a male-killing endosymbiont (Spiroplasma). The polymorphism is largely restricted to east and central Africa where three different colour forms meet and interbreed in a large contact or hybrid zone. The primary objective of this study is to present recent data on the polymorphism, sex ratio and the incidence of male killing in D. chrysippus populations in Rwanda. We also report previously unpublished data from a random sample collected in 1914 in Bujumbura in Burundi and on the differential effects of weather on males and females in Ghana from 1972 to 1974. We sampled butterflies using butterfly nets and either marked, recorded and released them or kept specimens for subsequent examination. We used PCR/microscopy on the preserved specimens to detect Spiroplasma and the presence of a protozoan parasite (Ophryocystis). Our findings suggest that Rwanda lies close to the western edge of the joint distribution of both Spiroplasma and the polymorphism. Further biogeographical studies are recommended to test the hypothesis that male killing is restricted to the contact zone in which polymorphism is commonly observed.

Heterosis, Haldane and Bateson-Dobzhansky-Muller effects have been widely documented amongst a range of plants and animals. However, typically these effects are shown by taking parents of known genotype into the laboratory and measuring components of the F1 progeny under laboratory conditions. This leaves in doubt the real significance of such effects in the field. Here we use the well-known colour pattern genotypes of the African monarch or queen (Danaus chrysippus), which also control wing length, to test these effects both in the laboratory and in a contact zone in the field. By measuring the wing lengths in animals of known colour pattern genotype we show clear evidence for all three hybrid effects at the A and BC colour patterning loci, and importantly, that these same effects persist in the same presumptive F1s when measured in hybrid populations in the field. This demonstrates the power of a system in which genotypes can be directly inferred in the field and highlights that all three hybrid effects can be seen in the East African contact zone of this fascinating butterfly.
