(047/XLmar) Xenylla maritima (Tullberg, 1869)

Xenylla maritima is moderately common species which is bluish black in colour and reaches 1.8 mm in length. Most records are from dry seashore debris, salt marshes and dry accumulated organic matter on the margins of saline water. However, there are also a few inland records from quite dry situations. Xenylla maritima has a long pointed furca in which the mucro dens is fused (Fig. 1). Seen from the side, the furca has a distinct bend (Fig. 2). Several specimens labelled 'Xenylla maritima' in the NHML collection have a mucro dens that is clearly separate so these specimens have been mapped as Xenylla humicola.
