Abstract

En este trabajo se documenta por primera vez el hallazgo de ejemplares de un crustáceo (Malacostraca, Bathynellacea) que vive exclusivamente en las aguas subterráneas de todo el mundo, en un hábitat inusual: el medio subterráneo superficial (MSS), un medio terrestre sin luz y saturado de humedad. Especímenes de la familia Parabathynellidae han sido encontrados en dispositivos de muestreo dispuestos para la recogida de fauna subterránea terrestre en el MSS del Parque Nacional de la Sierra de Guadarrama (Madrid, España). Se han identificado dos especies, de dos géneros diferentes, Hexabathynella nicoleiana Camacho, 1986 y Hexaiberobathynella mateusi (Galhano, 1967), mediante estudio morfológico. Las secuencias del gen 18S de varios ejemplares confirman su adscripción genérica. Estas especies eran ya conocidas en la provincia de Madrid.

Highlights

  • The mesovoid shallow substratum (“milieu souterrain superficiel”; MSS or terrestial SSHs) (Juberthie et al, 1980, 1981; Uéno, 1980, 1981; Pipan & Culver, 2012) is a terrestrial habitat that consist of a network of voids and interstices located above the deep subterranean domain and immediately below the soil, lightless and highly humid (Mammola et al, 2016)

  • We identified two species of the Parabathynellidae family in the collected material: Hexaiberobathynella mateusi (Galhano, 1967) (9 specimens; 5 ♂♂ and 4 ♀♀) and Hexabathynella nicoleiana Camacho, 1986 (3 specimens; 2 ♂♂ and 1 juvenile) (Fig. 4B; Table 1)

  • Since cryptic species are frequent among Bathynellacea (Camacho et al, 2011) we cannot discard that we have morphologically identified the specimens as belonging to these two species, it could be that they are sister species

Summary

Introduction

The mesovoid shallow substratum (“milieu souterrain superficiel”; MSS or terrestial SSHs) (Juberthie et al, 1980, 1981; Uéno, 1980, 1981; Pipan & Culver, 2012) is a terrestrial habitat that consist of a network of voids and interstices located above the deep subterranean domain and immediately below the soil, lightless and highly humid (Mammola et al, 2016). Bathynellacea were collected with traps set to sample terrestrial subterranean fauna in the Sierra de Fig. 1.— Distribution of subterranean sampling devices in the Sierra de Guadarrama National Park (Madrid, Spain) and (in red Bathynellacea specimens found).
