Fig. 19. Dolicheremaeus pseudofurcatus sp. n.: prodorsum in lateral view. — Fig. 20. Dolicheremaeus furcatus BALOGH, 1961 : prodorsum in lateral view. Notogaster: One unpaired, very large, rounded median condylus present, lateral ones (co. nl.) blunt or slightly concave anteriorly. Ten pairs of short notogastral setae present, six pairs of them blunt at tip, four pairs of them in pcsteromarginal position flagellate (Fig. 22). Notogastral surface rarely foveolate. Coxisternal region: Between the 2nd and 3rd-4th epimeres a wide median field pre­sent, epimeral surface framed medially (Fig. 24). Apodemes and epimeral borders — with the excep­tion of the 3rd ones — well developed, long. Epimeral surface ornamented by irregular spots. Epi­meral setae mostly long, thin, only median ones (la, 2a, 3a and 4a) shorter than the lateral ones. Pedotecta 2-3 angulate posteriorly, discidium large, with sharp posterior lateral corner. Anogenital region: Genital plates darker than the anal one. Ventral plate foveolate as is notogaster. Aggenital, anal and adanal setae flagellate or fine at tip, all of them long. Lyrifissures iad in apoanal position. — Legs: Type of the ultimate setae: L-S-S-S. Type material: Holotype (1290-HO-88): No. 105: deposited in the HNHM. Remarks : The new species is the third one in the genus Leptotocepheus BALOGH. 1961. It is distinguished from the other two by its flagellate posteromarginal setae (Pi-p 3 , h 3 ). Leptotocepheus macromucronatus sp. n. (Figs 25-28) Measurements — Length : 1049-1083 u.m, width : 451-525 p.m. Prodorsum: Rostrum wide. Lamellae long, thin, slightly curved inwards anteriorly. They reach out to the insertion of lamellar setae. Lateral lamelliform expansion (spa. I.) strongly curved, reaching to the insertion of rostral setae. Rostral and lamellar setae filiform at tip, interlamellar setae blunt at tip. Median pairs of prodorsal condyles very large, semicircular, connected with each other (Fig. 26). Lateral condyles smaller than the preceding ones, angular posteriorly. Sensillus thin, only slightly dilated distally, with some fine short cilia on its distal part, being shorter than the interlamel­lar setae. Lateral part cf podosoma: Pedotecta 1 very long, but narrow. Padotecta 2-3 large, with seme sharp projections. Exobothridial surface (Fig. 27) pustulate.
