description: Otiorhynchus dieckmanni Magnano, 1979
(Figs 4, 14, 32–34)
Material. 1 ♀ obtained on 16.06.2012 from a flowerpot that was transferred to the Curculio-Institute (CURCI) in Hannover in spring 2012.
Reared before in the climate chamber of JKI in Braunschweig. Rearing in flowerpots was started on 24.06.2011. Host plants were Ligustrum vulgare L. (2 pots) and Syringa vulgaris L. (3 pots). 16 specimens were released on these plants. The weevils were collected before in the Berggarten in Hannover-Herrenhausen by means of night catch on 21.06.2011 mainly on Dendranthema x grandiflorum (Ramat.) Kitam. cultivars.
General morphology. Body length: 8.00 mm (♀), width at the level of mesocoxae: 4.30 mm (♀), head width: 1.80 mm (♀). Body moderately slender, slightly curved, white to yellowish. Cuticle densely covered by minute hair-like cuticular processes. Rostrum short, almost as long as wide, surpassing procoxae in repose. Antennae moderately elongate. Pronotum almost 1.5 as wide as long. Ab. I–IV of almost equal length, next Ab. tapering towards the apex. Ab. IX distinctly smaller than other ones. Pseudocerci short, thorn-like, with sclerotized apical parts. Five pairs of functional spiracles placed laterally on Ab. I–V.
Chaetotaxy. Setae of unequal length, hair-like, yellow or brown, mostly based on protuberances. Macrosetae of head, rostrum, pronotum, femora and abdominal tergites dark brown, with curved apical parts. Microsetae light yellow, straight. Rostrum with a pair of es, 3 pairs of rs1-3 and a pair of pas; head capsule bearing 1 pair of vs, 2 pairs of sos1-2 and 1 pair of os1. Setae rs1-3, vs, sos1, os1 and pas long, well visible; mts1-2, es and sos1 very short, poorly visible. Pronotum with 2 pairs of as1-2, 2 pairs of: ls1-2, ds1-2 and pls1-2; all almost equal in length, well visible. Meso- and metathorax each with 4 pairs of short d1-4. Each tergal part of Ab. I and II with 5 pairs of short d1-5, almost equal in length and located posteriorly in regular lines. Ab. III–VIII each with 5 pairs of d1-5, equal in length, located posteriorly in regular lines, a pair of setae (d0) placed antero-medially (d0: usually small, hair-like, poorly visible, placed always separately from other ones; observed on a part of the abdominal segments, sometimes only on Ab. VII–VIII), 2 pairs of l1-2 located near the tergum-sternum border and 3 pairs of very short v1-3. Ab. VIII with 5 pairs of long d1-5, almost equal in length, located posteriorly in regular lines, 2 pairs of short l1-2 and 2 pairs of v1-2. Ab. IX with 4 pairs of medium long v1-4. Abdominal setae and their protuberances increasing gradually from Ab. II to VIII. Each apex of femora with 2 hair-like setae (fes1-2), almost equal in length.
