( Fig. 77 ), when digging for the pupae of Otiorhynchus ligustici , a species that is present in huge numbers at this site. This date was apparently too late for collecting O . ligustici pupae. General morphology. Body length: 6.70 mm (♀), width at the level of mesocoxae: 3.70 mm (♀), head width: 1.25 mm (♀). Body rather slender, straight, dark grayish. Cuticle smooth. Rostrum short, almost 1.1 as long as wide, surpassing procoxae in repose. Antennae rather short. Pronotum almost 1.3 as wide as long. Ab. I–IV almost of equal length, slightly smaller than Ab. V–VIII; Ab. IX reduced, distinctly smaller than previous ones. Pseudocerci elongate, narrow, slightly curved inward. Five pairs of functional spiracles placed laterally on Ab. I–V. FIGURES 49–51 .

Sampling sites of pupae or mature larvae (reared to pupae) of field-collected species. 72 and 73—sampling site and habitat of Brachyderes incanus and Strophosoma c.f. sus larvae or pupae near Berkhof (09.07., 02.09.2012): a sand pit with naturally grown Calluna and Pinus vegetation; 74—sampling site of mature larvae of Phyllobius intrusus under Chamaecyparis obtusa ‘Crippsii’ in a tree nursery in Bad Zwischenahn, 29.03.2011; 75—sampling site of a pupa of Phyllobius pyri s. str. at the border of Helstorf peat bog, 21.04.2012; 76—sampling site of Barypeithes pellucidus pupae: a bed of Bergenia cordifolia ‘Admiral’ in a garden near Hildesheim, 06.04.2011; 77—sampling site of a Tanymecus palliatus pupa in a Medicago sativa field near Cottbus on fly ash soil, 0 9.08.2011 (photos: P. Sprick). Chaetotaxy. Setae different in shape and length, yellow, dark brown or black, based on conical, sclerotized protuberances. Rostrum with 5 pairs of hair-like setae ( rs1-5 ); head capsule bearing 1 pair of vs and sos ; both slightly curved, located on conical protuberances. Pronotum with paired as1-2 , sls1-2 , ds1-2 and pls1-2 . All setae almost equal in length and slightly curved. Mesothorax with 2 pairs of short setae ( d1-2 ); metathorax with 3 pairs of short setae ( d1- 3 ). Tergal part of each Ab. I–VIII with 6 pairs of d1-6 , different in length, arranged posteriorly in regular lines. Ab. IX with 3 pairs of very short v1-3 . Abdominal setae and their protuberances, especially d1 , d3 , d6 , increasing gradually from Ab. I to VIII. Each apex of femora with 2 hair-like setae ( fes1-2 ), different in length.
