ABSTRACT
A new myobiid species Radfordia (Hesperomyobia) sigmomys sp. n. (Acari: Myobiidae) ex Sigmodon alstoni (Rodentia: Sigmodontidae) from Central America is described. This description is based from the females, proto-, dueto- and tritonymphs. Female (4 spec.). Body 500-510 (in micrometers) long and 295-320 wide. Length of setae: ve 90-95--widely lanceolate, 10-15; vi 23-25, sci 95-105, sce 90-100, d1 80-85, d2 70-90, d3 20-25, d4 23-27, l1 75-90, l2 80-85, l3 25-27--all narrowly lanceolate; d5 10-15, l4 10-15, ic1 25-30, ic2 80-90, ic3 85-90, ic4 15-18, pg1 10-15, pg2 30-40, pg3 8-10--all hair-like. Protonymph (2 spec.). Idiosoma with 14 pairs of dorsal setae, including el and 2 pairs of very short anal setae, and 4 pairs of ventral setae, including l5. Length of setae: vi 25, ve 23-25, sci 50-52, sce 125-130, d1 18, d2 16, d3 10-12, l1 10-15, l2 12-16, l3 10-13--all lanceolate; d4 6, ic1 l1, ic2 25-27, ic3 15--all hair-like. Leg chaetotaxy II-III: II coxa 0--trochanter 0--genu + femur 2 (1 solenidion)--tibia 4--tarsus 7 (1 solenidion), III 0-0-0-3-6. Deutonymph (2 spec.). Setae 14 added. Length of setae: vi 25-27, ve 30-35, sci 65-70, sce 120-155, d1 20, d2 16-18, d3 11-13, d4 10-13, l1 20-27, l2 10-15, l3 l1--all lanceolate; l4 6, ic1 13-15, ic2 35-40, ic3 25--all hair-like. Leg chaetotaxy II-III: II 0-0-3(1)-4-7(1), III 0-0-1-3-6. Tritonymph (2 spec.). Setae d5 and ic4 added. Length of setae: vi 34(35), ve 45(40), sci 80(75), sce 140(150), d1 23(25), d2 25(25), d3 13(10), d4 13(10), l1 100(90), l2 22(25), l3 25(27)--all lanceolate; l4 6(5), d5 4(5), ic1 12(15), ic2 45(50), ic3 35(40)--all hair-like; setae 14 microchaetae. Leg chaetotaxy II-IV: II 1-1-3(1)-4-7(1), III 0-1-1-3-6, IV 0-0-1-3-4. This new species is closely related to R. (H). sigmodontis Radford, 1951 ex Sigmodon hispidus from USA. The females of these two species are not distinguishable from each other. While the tritonymphs differ by the following characters. In R. (H.) sigmomys sp. n., the length of setae ic2 and ic3 are 40-50, sci--75-80, l1 90-100. In R. (H.) sigmodontis, the setae ic2 and ic3 are microchaetae, the setae sci and l1 are 30-40 and 10-15 in length respectively.

The mite Eudusbabekia rhinophylla n. sp. is described from the bat Rhinophylla pumilio Peters in Ecuador. It is considered to be a member of the subgenus Eudusbabekia, differing from other representatives of this group by the lanceolate shape of the coxal setae.

The authors describle 5 new species of mites of the family Sarcoptidae. Among these psecies 4 belong to the genus Chirnyssoides and one to the genus Notoedres, subgenus Bakeracarus. They correct and complete their previous observations on these genera of mites.
