Notogaster: Surface rarely foveolate. Ten pairs of notogastral setae present, one of them short, blunt at tip, all other long (Fig. 1), flagellate. Notogastral condyles also nearly equal in length like prodorsal ones, but the lateral pair (co. pi.) reaching in front of the median one. Lateral part of podosoma: All pedotecta and discidium large. Exobothridial surface pustulate. Coxisternal region: Anterior margin ornamented by large alveoli (Fig. 4). The other surface of the epimeral region smooth or only with some irregular spots. All epimeral setae thin, simple; setae lb, 3b and 4b longer than the others. Anogenital region: Surface with some rugae anteriorly (Fig. 4), some small foveolae also observable in posteromarginal position. All setae thin, simple. Adanal setae much longer than the anal ones. Lyrifissures iad in adanal position. Legs: Type of the ultimate setae : L-L-L-L. Type material: Holotype (1287-Ho-88): No. 105, deposited in the HNHM.* Remarks : The new species in well distinguishable from the other species of the genus Dolicheremaeus JACOT, 1938 by the wide, sculptured transversal band consisting of alveoli in the anterior part of the coxisternal region. Dolicheremaeus obtusisetus sp. n. (Figs 5-9) Measurements — Lenght : 943-968 urn, width : 426-460 urn. Prodorsum: Rostrum conical, its surface foveolate. Lamellae running parallel basally, but strongly convergent anteriorly, reaching far out from the insertion of the lamellar setae. Rostral setae shorter than lamellar one, both pairs setiform, without flagellate end. Interlamellar setae thick, blunt at tip. Interbothridial region irregularly foveolate, a part of the surface, along lamellae, granulate. Sensillus slightly fusiform (Fig. 5), exobothridial region pustulate. Lateral lamelliform expansion reduced (Fig. 9). Both pairs of prodorsal condyles weakly developed (Fig. 8), median part flat. Notogaster: Whole surface distinctly foveolate. Ten pairs blunt notogastral setae of nearly equal length (Fig. 6). Lyrifissures ih and ips originating in front of setae h 3 . Lateral part of podosoma: Surface of pedotecta 1 foveolate, region beside it pustulate. Pedotecta 2-3 quadrangular. Coxisternal region: Epimeral surface foveolate. All epimeral setae setiform, finely roughened (Fig. 7), but some of them ( la, 2a, 3a ) blunt at tip. Epimeral borders and apodemes well observable, bo. 4 thin, without any sculpture (opp. by AOKI 1967) along them. Anogenital region: Genital and aggenital setae setiform, fine at tip, anal and adanal setae blunt at tip. Lyrifissures iad in paraanal position. Legs: Type of the ultimate setae : L-L-L-L. Solenidium <p 2 blunt at tip, œ 1 and a> 2 almost equal in length. Type material: Holotype (1292-HO-88): No. 105; 1 paratype from the same sample. Holotype deposited in the HNHM, paratype in the MHNG.** Remarks : The new species is well distinguishable from all other Dolicheremaeus JACOT, 1938 species by the characteristic blunt at tip notogastral and adanal setae and the sculpture of the prodorsum and pedotecta 1. [Dolicheremaeus phyllotrichus sp. n. (Figs 10-14) Measurements — Length: 1435-1517 u.m, width: 705-800 urn. Prodorsum: Rostral surface smooth, interlamellar surface well foveolate. Lamellar and rostral setae setiform, latter shorter but more distinctly barbed than the other. Lamellae long, gradually converging anteriorly. Lateral lamelliform expansion short, but wide, not reaching to the insertion of rostral setae. Interlamellar setae blunt at tip, longer than lamellar ones. Sensillus setiform without any thickening. Median prodorsal tubercles very large, stronly convex, semicircular (Fig. 11), the lateral ones (co. pi.) much smaller than the preceding one. •Hungarian Natural History Museum, Budapest. ** Museum d'Histoire Naturelle, Genève.
