gination 0.25-0.4 times as large as its median length. OOL : POL : OCL = 0.9-1.1 : 1.0: 0.9-1.1. Head subparallel or slightly narrowed behind the eyes. Length of the third/length of the fourth antennái segment = 0.8-1.1. Length /maximal width of the eighth antennái segment - 4.3-5.0. Length of antenna/length of costa = 1.1-1.2. Mesoscutellum densely and roughly punctured without interspaces. Mesoscutellar appendage smooth and shining. Metascutellum smooth and shining in the middle and with a row of punctures on hind margin. Mesopostnotum with fine transverse sculpture. Metapostnotum smooth but not shining. Distance between two cenchri/length of cenchrus = 0.9-1.2. Mesepisternum densely and deeply punctured without interspaces. Mesepimeron densely and roughly punctured with shallow and large punctures without interspaces. Metepisternum and metepimeron shining with dense undefined surface sculpture. Mesosternum shining, sporadically punctured with minute punctures. Length of basitarsus/length of hind tibial spur = 1.1-1.2. First abdominal tergum smooth and shining with sporadic punctures on the base. Penis valve rounded with a minute thorn as shown in Fig. 1. Length of fore wing: 6.2-7.0 mm. Length: 6.8-7.1 mm. Holotype: male. "Budakeszi Hársbokorhegy 1954 IV. 8.", "leg. Bajári". Paratypes: three males labelled as the holotype, three males: "Palota ápr. 5", one male: "Palota ápr. 19", one male: "Budapest", one male: "Rákos márc.26", one male: "Csepel Cerva", one male: "Palota márc 25". Palota = Rákospalota, district of Budapest. Holotype and paratypes are deposited in the Hungarian Natural History Museum. Every specimen was collected around Budapest. The last data of collection is 44 years old. Since this time their habitats have been destroyed and built in and the new species is problaby extinct. Its female was not found in the collection and as a result of the habitat destruction, the female will remain unknown. The new species belongs to the subgenus Poodolerus Zhelochovtsev, 1988. Its closest relative is Dolerus hibernicus Lacourt, 1988 but D. hibernicus is larger, 7.0-8.0 mm, head behind eyes is strongly contracted, its mesosternum is densely punctured and lst-3rd terga are nearly smooth and shining. Penis valve is shown in Fig. 2. Fig. L: Penis valve of Dolerus nigrominutus sp. n. Fig. 2.: Penis valve of Dolerus hibernicus Lacourt, 1988
