Remarks
This species is mainly associated with stony seasonal rõÂos and arroyos in the Sierra Morena and its westward upland extension towards the Portuguese border. It is morphologically very similar to Metacnephia amphora Ladle and Bass from southern England and France and it is doubtful if the two are distinct species (Crosskey in Crosskey and Howard, 1997: 91). However, study of the larval polytene chromosomes (for nuragica based on specimens from our collection in the RõÂo Guadamatilla, Site 85) has shown that those of M. nuragica diOEer from those of M. amphora by one ®xed inversion in chromosome IIIL and by two ¯oating inversions (P. H. Adler, personal communication). These diOEerences do not prove that the two entities are separate valid species but we treat them as such pending better knowledge. Metacnephia nuragica can be readily recognized in the Andalusian fauna by the 14-®lamented pupal gill, cocoon in the form of a long loose net-like sleeve rasied anteriorly above the substrate (usually stuck to neighbouring cocoons), and by the amphora-shaped larval postgenal cleft.
