Figs. 117–127 View FIGURES 117–123 View FIGURES 124–127

Studied material. Tarragona , Sierra de Llabería, 4 May 2009, from soil samples collected by C. Hernando, male holotype and 1 female paratype, deposited in MNCN, type number 2239 .

Description. Body length of male 10 mm, female 11 mm. Body yellowish, dorsally more intensely pigmented. Macrosetae with a moderate degree of spiralization; those inserted in the coxae with 4–6 turns ( Fig. 117 View FIGURES 117–123 ). Head with few bifid macrosetae and dispersed thin and short setae, which are more abundant in the occipital region ( Fig. 118 View FIGURES 117–123 ).

Antennae of the male symmetrical; pedicellar apophysis subcylindrical as in C. maggii but more narrow, approximately 5 times longer than the basal width and reaching the level of the fourth joint of the flagellum. Width of apophysis about half that of basal part of flagellum. Apical seta not well developed, almost completely sunken in the tegument ( Fig. 119 View FIGURES 117–123 ).

Distal article of the maxillary palp 3.4–3.8 times longer than wide and about 1.5 times longer than the penultimate article ( Fig. 120 View FIGURES 117–123 ). Labial palp typical of the genus.

Nota without special characters. Tibiae short (L/W ratio of protibia, mesotibia and metatibia: 3.15–3.35, 3.35–3.5 and 4.20–4.35, respectively), with 1 or 2 dorsal and 4 ventral spines; lateral spine usually present, lacking on some protibiae and mesotibiae.

Urotergites I–IX typical of the genus. Tenth urotergite of male with concave hind border between the posterolateral lobes, the concavity about as wide as long ( Fig. 121 View FIGURES 117–123 ). Four sensory pegs on each posterolateral lobe and an additional peg present in a more basal position ( Fig. 122 View FIGURES 117–123 ). Female tenth urotergite with concave posterior border, its disc densely covered with thin setae ( Fig. 123 View FIGURES 117–123 ).

Urosternites I–VII as usual, bearing 1+1 discal macrosetae. Eighth urosternite of male with a very protruding and convex hind margin ( Fig. 124 View FIGURES 124–127 ).

Parameres as long as stylets IX, and almost 5 times longer than wide. Subgenital plate of the female nearly as wide as long (L/W ratio about 0.9), with its apex acutely convex ( Fig. 125 View FIGURES 124–127 ). Ovipositor long, with 23 divisions, surpassing the level of the ninth stylets by more than 3 times their length ( Fig. 126 View FIGURES 124–127 ).

Male cerci with 6 or 7 elongated, acute pegs, with two pairs inserted at the same level ( Fig. 127 View FIGURES 124–127 ). Paracercus with a basal series of 4 long, striated acute spines.

Etymology. The specific name is dedicated to Carlos Hernando from Barcelona, who collected the soil samples where these insects were found.

Remarks. Coletinia hernandoi n. sp. is closely related to C. maggii because of the subcylindrical shape of the pedicellar apophyses; the remaining known species of Iberian Coletinia have more complex antennal apophyses. Some additional features are within the normal variation of C. maggii , such as the shape and number of sensory pegs of the tenth urotergite in the male, L/W ratio and setation of the tibiae, and length and number of divisions of the ovipositor. However, these specimens cannot be included as C. maggii because of the different development of the male antennal apophyses, which are very narrow and long compared with those of C. maggii . In Iberian C. maggii , these apophyses are about 3 times longer than wide, and their width is only slightly less than the width of the basal divisions of the flagellum. Central European C. maggii have apophyses with a similar L/W ratio and the basal flagellum is about 2 times wider than the apophysis ( Wygodzinsky, 1980, also see Figs. 3B, 3C, 4A, 4B View FIGURES 3, 4 and 5E View FIGURES 5, 6 of current paper). In C. hernandoi n. sp., the male antennal apophyses are approximately 5 times longer than wide and very narrow compared to the width of the flagellum ( Fig. 119 View FIGURES 117–123 ). It is not reasonable to consider this difference to fall within the range of variability of C. maggii .

The shape and setation of the tenth urotergite of females of C. maggii and C. hernandoi n. sp. are clearly different. Females of C. maggii show a straight hind margin of this urotergite, but the specimen from Tarragona shows a clearly concave hind margin. In C. maggii the disc of the tenth urotergite of females is devoid of setae, with at most a few small setae inserted near the lateral margins, but in the new Iberian species, the female bears dense setation on the disc of this urotergite ( Fig. 123 View FIGURES 117–123 ). Some other features appear to be different in the new species, such as the shape of the eighth urosternite of the male, whose hind margin is not as truncated as in C. maggii (compare Figs. 124 View FIGURES 124–127 and 168 View FIGURES 164–172 in the current paper and Figs. 3L View FIGURES 3, 4 and 5A View FIGURES 5, 6 in Wygodzinsky, 1980), but more robust conclusions cannot be made unless more specimens are available.
