This paper spells out the following line of thought: (A) How much we care about various things is in constant flux, even as the world remains as it was. Internal affective shifts due to changes in mood, arousal-states or even hunger cause us to be more or less concerned about something. (B) Further, there often isn't any fact of the matter about how much we ought to care about something. As I argue, it isn't the case that there are prudential or moral norms that fix how worried we should be about every state of affairs in the world. (C) And this suggests that what we should do, both prudentially and morally, is often subject to our affective shifts, at least if how much we (permissibly) care about something is an important element of practical reasoning.

Abstract

Riffle bugs in the genus Rhagovelia have diversified extensively on the island of Madagascar. The current paper defines and segregates a distinct set of species within this endemic assemblage as the diabolica group, containing the previously described species R. diabolica Poisson, R. beangonyi Poisson, and R. milloti Poisson, as well as the following new species described herein: R. compacta and R. suarezensis from northern Madagascar; R. manankazo and R. angulata from central Madagascar; and R. madecassa, R. scupturata and R. origami from eastern Madagascar. Figures of key morphological characters, including male parameres are provided for all species, accompanied by distribution maps.

Riffle bugs in the genus Rhagovelia have diversified extensively on the island of Madagascar. The current paper defines and segregates a distinct set of species within this endemic assemblage as the tesari species-group, containing the previously described species R. tesari Hoberlandt, R. adrienneaebrasili Poisson, R. hovana Hoberlandt, R. abalienata Hoberlandt, R. tsaratananae Poisson, and R. mohelii Poisson (originally described as a subspecies of R. tesari but here raised to full species status), as well as the following 13 new species described herein: R. aquacola n. sp., R. ambra n. sp., and R. sahabe n. sp. from northern Madagascar; R. mandraka n. sp., R. faratsihoi n. sp., and R. wenzeli n. sp. from central Madagascar; R. enckelli n. sp., R. takona n. sp., R. manga n. sp., R. brincki n. sp., and R. sandoka n. sp. from eastern Madagascar; R. andringitrae n. sp. from south-central Madagascar; and R. mondena n. sp. from southeastern Madagascar. Rhagovelia tesari flavomarginata is synonymized under R. adrienneaebrasili . Figures of key morphological characters, including male parameres are provided for all species, accompanied by distribution maps.
