Agauopsis microrhyncha (Trouessart, 1889)

Material examined

Five males (FDHAL-21/3), one deutonymph, El Pris ( Gelidium sp. , upper-mid littoral zone); three females, six males, La Barranquera ( Corallina ferreyrae , mediolittoral zone).

Diagnosis

Idiosoma length in females was 420–430 µm, in males, 360–430 µm and in deutonymph 350 µm. Idiosoma wide, flattened and heavily armed. AD and PD slightly raised longitudinal costae. AD areola M-shaped and the plate slightly longer than wide. OC with two corneae. The species can easily be recognized by having a ventral and two anterior spines on telofemur I, a ventral and three anterior spines on tibia I, two of which are adjacent ( Fig. 3C ) ( Pepato and Tiago 2003; Mytilineou et. al. 2016; Durucan 2021).

Remarks

This species is present, at least, in the Mediterranean Sea and eastern Atlantic Ocean ( Viets 1940; Bartsch 2009). The morphological characteristics of the specimens reported here accord with records previously given by Mytilineou et al. (2016) and Durucan (2021).
