Abstract: |
|
| |
|
Brotheochactas fei
sp. n, from Manaus, State of Amazonas, Brazil, is newly described. B.
fei belongs to the Brotheochactas species-group, and differs
from the remaining species by having two lateral eyes, a reddish
carapace, finely granulate tergites and a nearly smooth telson. Based on
two sampling methods, different estimates of abundance were obtained:
0.0027 and 0.022 ind/m2. These values are low when compared
to the abundance of other sympatric scorpion species. The species is
apparently termitophile (27 out of 30 specimens were collected in
termite mounds). They were found associated with 13 species of termites
from 3 subfamilies. However, females with young were more frequent in
the mounds of apicotermitine termites. |

Resumen: |

|
Broteochactas fei
n.sp. es descrito de Manaus, Estado de Amazonas, Brasil. Pertenece al
grupo de especies Brotheochactas, donde difiere del resto de las
especies por presentar dos ojos laterales, carapacho rojizo, terguitos
finamente granulados y telson casi liso. A partir de dos métodos de
muestreo se estimaron abundancias diferentes de 0,0027 y 0,022 ind/m2.
Estos valores pueden considerarse bajos cuando son comparados con la
abundancia de otras especies simpátricas de escorpiones. La nueva
especie es aparentemente termitófila (27 de los 30 especímenes fueron
colectados en termiteros), encontrándose asociada a 13 especies de
termitas pertenecientes a tres subfamilias. Sin embargo, hembras con
juveniles fueron colectadas, con mayor frecuencia, en termiteros
pertenecientes a especies de Apicotermitinae. |
