RESUMO:

 

The Brazilian fauna of semi-aquatic bugs (Insecta: Heteroptera: Gerromorpha)
is poorly known in most of the national territory, with sampling and studies
concentrated on northern and southeastern regions, while the northeastern is
still underexplored. This is especially evident when analyzing the states of
Alagoas and Sergipe, where only three species have been recorded so far. The
present study aims to increase our knowledge on the diversity and distribution
of Gerromorpha from Alagoas and Sergipe by obtaining specimens, recording
new occurrences, elaborating lists of species, generating models of potential
distribution, and determining key areas for sampling or conservation. A total of
2,792 specimens were collected, belonging to 39 described species, 16 genera
and five families. Among them, 31 represent new records from Alagoas and 32
from Sergipe. Ecological niche modelling was performed only for species with at
least ten occurrence localities within the study area. Therefore, eleven species
were analyzed: Mesovelia mulsanti White, 1879, Me. amoena Uhler, 1894
(Mesoveliidae); Limnogonus aduncus Drake & Harris, 1930, Brachymetra
albinervus (Amyot & Serville, 1843), Rheumatobates crassifemur schroederi
Hungerford, 1954 (Gerridae); Rhagovelia tenuipes Champion, 1898, R. whitei
(Breddin, 1898), Platyvelia brachialis (Stål, 1860), Microvelia venustatis Drake &
Harris, 1933, Mi. quieta Drake & Carvalho, 1954, and Mi. pulchella Westwood,
1834 (Veliidae). Species occurrence was related to environmental suitability
and compared to biomes of the mesorregions of Alagoas and Sergipe, and of
their federal conservation units. Potential species richness was also related to
lotic and lentic systems. The study shows that a lot of work is still needed in
order to know in more detail the geographic distribution of semi-aquatic
heteropterans from the states of Alagoas and Sergipe, and of the country as a
whole.
