Paraeumigus lopezi  n. sp.

Material examined. Morocco, near Tamanar (South of Smimou), 30 ° 58 ' 40.09 ", 9 ° 42 ' 6.40 " 24.I. 2005, ♂ holotype, ♀ allotype, ♂ paratype, leg. Heriberto Lopéz (BMCP).

Among some specimens of Pamphagidae  collected by the Spanish colleague Heriberto Lopéz in Morocco I found three small specimens whose characteristics are not matching with those of any described species; the locality where they were collected, next to the Atlantic coast, is far from any other housing Paraeumigus  species, that till now were considered as typical mountainous elements.

Diagnosis. It is a small sized species (see Table 3), with moderately raised pronotum keel; body is laterally compressed.

Description. Antennae 15–16 (males) and 16 - (female) segmented, shorter than head and pronotum together. Teguments are rather wrinkled, fore and hind borders of pronotum clearly protruding, pronotum posteriorly enlarged, with a central stout keel (not furrowed in the males, just furrowed in the female) and two lateral keels, more or less parallel ( Figs. 141, 143, 145View FIGURES 123 – 148. 123 – 145). Pronotum keel in lateral view is just raised in the males, clearly raised in the female, gently interrupted by typical sulcus ( Figs. 141, 145View FIGURES 123 – 148. 123 – 145). Central keel is visible also on the first segments of the abdomen. Tegmina are 2.4–2.5 longer than high and are more or less unicolor, with the upper part just clearer than lower one. Mesosternal space is 2.0 times wider than long, and metasternal space 2.5 times wider than long ( Fig. 155View FIGURES 149 – 160). Krauss organ smooth. Prosternal process has an evident fore collar and two pointed hind tubercles ( Fig. 142View FIGURES 123 – 148. 123 – 145). Aedeagus valves, from back view, have long and narrow lobes, enlarged at the apex; central columnar keels arrive to the apex, while the other two remain only in the basal part, which is as wide as long ( Fig. 144View FIGURES 123 – 148. 123 – 145). In lateral view, aedeagus valves are apically flattened and pointed, the epiphallus shows ca. 35 small spines on the central sides ( Fig. 144View FIGURES 123 – 148. 123 – 145).

Habitat. Specimens were collected in a plain with dispersed Argania  trees and a high density of annual grasses.

Biological notes. The collector, H. Lopéz, found the specimens as nymphs; they were kept in a plastic container and were feeding with Plantago  sp., mulberry, Rumex lunaria  and lettuce. Every day, the container was revised to detect possible moulting, mating and/or song emissions. Males were adult on 16 th March and 21 st April, the female on 29 th March. One male remained at the second nymph instar for 55 days and at the third instar for 11 days, the other male remained at the third instar for 50 days; the female remained at the third instar for 38 days and at the fourth instar for other 25 days. Mating occurred in the first days of May ( Fig. 161View FIGURES 161).

Derivatio nominis. I gratefully name this species after Heriberto Lopéz, specialist of Orthoptera  from Tenerife, who in the last years has published some valuable papers on endemic species of Pamphagidae  of Canary Islands and collected and sent me a series of Moroccan interesting specimens.
