03EE87E2FFFCFFA6F612FFF7FBB7FADE.taxon	etymology	Etymology This species is named after the markedly curved spine-like scutal tubercle or hump (from the Latin: curvus meaning curved, spinus meaning spine) on the thoracic suture of the pupal exuviae. A scutal tubercle is also present on the scutum of the adult. The name curvispinus is treated as a noun in apposition.	en	Moubayed-Breil, Joel, Ashe, Patrick, Langton, Peter H.

Distinguishing characters for the male are: AR = 1.2; hairs present on the anteromedian inner margin of the eyes; Palp 5 - segmented, without sensilla clavata; 4 th palpomere with cordiform apex and lacking circular patch of microtrichia; thorax with a markedly distinct scutal tubercle mediodorsally; sternapodeme with a characteristic V-like base, bearing two pointed anterior horns; anal point wider at base and progressively narrowed distally, in lateral view crests include 2 sharp points medially, proximal one the smaller; posterior margin of superior volsella rounded; digitus swollen at base, not uniformly tapering apically; median volsella not flattened distally, bearing about five spatulate setae; inferior volsella with distal ¼ swollen and bearing a tuft of short dark setae on distal ¼ inner margin, ventral setiferous lobe with 3 straight stout setae bent downwards. Pupal exuviae characters key to those of P. bituberculatus except: pattern and granulation of thoracic suture and scutal hump (hump pointed and granulations extended anteriad and posteriad); shape of median patch on tergite VI only composed of short dark spines.	en	Moubayed-Breil, Joel, Ashe, Patrick, Langton, Peter H.

03EE87E2FFFCFFA6F612FFF7FBB7FADE.taxon	discussion	Remarks P. curvispinus sp. nov. is closely related to P. bituberculatus on the basis of both male imagines and pupal exuviae. The following combination of distinguishing features for the male are: posterior margin of superior volsella rounded in P. curvispinus (Figure 40), straight in P. bituberculatus; digitus swollen at base, not uniformly tapering distally; median volsella short and bearing more than 10 spatulate setae apically in P. bituberculatus, while in P. curvispinus it has only about 5; ventral setiferous lobe of inferior volsella with 3 stout setae instead of 4 in P. bituberculatus. Pupal exuviae of P. curvispinus sp. nov. can be easily distinguished from those of the bituberculatus- complex on the basis of the following characters: pattern and granulation of thoracic suture (Figure 17, granulations extended anterior and posterior, hump pointed); shape of the median patch on tergite VI (Figure 30).	en	Moubayed-Breil, Joel, Ashe, Patrick, Langton, Peter H.

03EE87E2FFFFFFABF60CFAF7FCB7FB35.taxon	discussion	Remarks and geographical distribution Reiss & Säwedal (1981: 94) in a key indicate that the pupal exuviae of P. bituberculatus has a thoracic horn but in Langtom (1991: 327, Plate 132 b) the thoracic horn is regarded as absent in this species and the latter viewpoint is accepted here. The pupal exuviae of P. bituberculatus resemble closely those of P. corsicanus, P. curvispinus and P. oconnori. Main separating characters for P. bituberculatus are: thoracic suture (Figure 16) lacking granulations on both anterior and posterior half; thoracic horn absent; scutal hump faintly granulose and not domed (Figure 16); pearl row on the wing sheath (Figure 20), not reaching the nose; median patch on tergite VI (Figure 29) circular, bearing faint to weakly darkened points; genital sac of male covered with granulations (Figure 33 a), genital sac of female (Figure 33 b) lacking granulations apically. However, some variation in the male imagines and the pupal exuviae P. bituberculatus from Italy include: tubercles on anal tergite of male bearing only a single seta; thoracic suture with faint granulations on anterior half; D 5 on tergite III taeniate. DISCUSSION Associated material composed of pupal exuviae and pharate males belonging to the bituberculatus - complex (with pupae that key to P. bituberculatus in Langton 1991 and Langton & Visser 2003) described here demonstrates that there is a risk of misidentifying pupal exuviae similar to P. bituberculatus as P. bituberculatus. Consequently, we believe that populations of P. bituberculatus from Europe and neighboring regions include about five new species, which key to P. bituberculatus as pupal exuviae. It appears that true P. bituberculatus is more a northern element than a widespread species throughout the Palaearctic Region. Therefore, the presence or absence of P. bituberculatus from some subregions in Europe and the Mediterranean Region needs to be reviewed and confirmed on the basis of pharate males or adult males, in particular from southern Europe (including Portugal, Spain, France, Italy, Greece) and the Near East. Details on both the taxonomy and biogeography of the bituberculatus - complex are given in a separate paper in preparation. In the bituberculatus - complex, based on the morphology of both male adult and pupal exuviae, there appear to be several species groups, one centering on P. bituberculatus with several close but distinct sister species and another which includes only P. corsicanus sp. nov. Further investigations throughout Europe, North Africa and the Near East are necessary to determine if imaginal and pupal features support each other and enable the creation of species groups within the entire genus. Paratanytarsus. bituberculatus has been previously accepted as having a widespread distribution throughout the Palaearctic Region including southern Europe, the Near East and North Africa. Our investigations show that several species morphologically similar to P. bituberculatus, occur in the Mediterranean Basin region. Two of these, P. curvispinus and P. oconnori, which we consider members of the bituberculatuscomplex, are described in this paper. In the light of these new discoveries the geographical distribution of P. bituberculatus needs to be reviewed by focusing especially on examining pharate males and adult males. Taxonomic information given in this paper provides additional characters for keying any further related species which fall into the bituberculatus - complex. Additional future work needs to be done on both the taxonomic composition and geographical distribution of all members of the bituberculatus - complex. The biological quality of both water and sediment in wetland areas and lower reaches of coastal rivers is seriously damaged by the impact of organic and chemical pollution in many countries around the Mediterranean Basin. Furthermore, despite extensive investigations during the last three decades in southern France and Lebanon, only a few pharate males and pupal exuviae belonging to the bituberculatus - complex have been obtained. Coastal aquatic ecosystems including coastal rivers in southern and western France (Mediterranean and Atlantic coastal areas) have been heavily affected by toxic chemical pollutants such as HAP’s and PCB’s. The latter products combined with the anti-mosquito solution BTI and the past use of pesticides such as Fipronil and Lindane (which remain in the sediments and take a long time to breakdown) can lower the chironomid diversity in coastal habitats by 30 to 50 % (Moubayed-Breil, personal observation).	en	Moubayed-Breil, Joel, Ashe, Patrick, Langton, Peter H.
