Siteroptes kaszabi MAHUNKA, 1969 New localities: As-12 (3); As-110 (1). Pygmephoridae Pediculaster kaszabi sp. n. Length: 285 u,, width: 150 u.. Dorsal side (Fig. 6): Propodosoma narrow, rostrum long. Stigmata guttiform, rather removed from one another. Vertical and inner scapular hairs arising near one another, behind posterior margin of stigmata. Outer scapular hair longest of all somatic hairs, originating near base of propodosoma, externally to bothrydia. Among hysterosomatic hairs, setae humerales standing along a common transverse line, inner pair shorter than outer one. Lumbal hairs of approximately equal length, but outer pair of sacral setae only half as long as inner one. All dorsal hairs very densely ciliate. Ventral side (Fig. 7): Anterior sternal plate large, apodemes well developed. Hairs arising on coxal fields thin but relatively long, especially those on coxal field 2. Apodeme 3 completely evolved on posterior sternal plate, in contrast to apodemes 4 and 5; their conjunction with ventrum hardly interprétable. No essential difference in size between prae- and poststernal as well as axillary hairs; prae- and poststernal ones emerging along a common longitudinal line. Setae caudales mediae longest of all caudal hairs, arising immediately beside or slightly anteriorly to externae. Legs: Tibiotarsus of leg I (Fig. 8) slightly incrassate, claw well developed. Solenidion co

x very long, bacilliform, longer than greatest width of tarsus. Solenidion co

2 of similar shape but one-third shorter. Solenidion qp

x bacilliform, cp

2 fusiform, and both essentially shorter than preceding ones. Hair / comparatively short, hair / longer than hair a. Hair c of femur bacilliform, a generic character. Entire surface of all legs punctate, similarly to that of body. Pulvilli of legs II and III minute. Hair o longest hair on tarsus of leg IV (Fig. 9). Type-material: 1 ex. (Holotype: T-1186 p-69): As-100. Remarks : A similarly long solenidion co

1 on the tibiotarsus of leg I is known only in Pediculaster ignotus KECZAL, 1959, but the configuration of solenidia co

2 and (p

x 2 is completely different. The position of the median caudal hairs is also singular und unknown in all hitherto described species. I dedicate the new species, in gratitude and esteem, to Dr. Z. KASZAB, the collector of the extraordinarily rich material. Pediculaster mesembrinae (R. CAN., 1880) New locality: As-100 (8). Pediculaster mongolicus sp. n. Length: 301-332 p, width: 150-174 p. Dorsal side (Fig. 10.): Surface punctate. Propodosoma narrow, rostrum long. Stigmata removed from one another. Vertical and inner scapular setae short, situated along a common transverse line, outer scapular hairs very long. Except
