Typhlodromus (Anthoseius) cephalochaitosus  n. sp. ( Fig. 5View FIGURE 5)

DIAGNOSIS – Based on the keys to Typhlodrominae  provided by Chant & McMurtry (1994), this species would be identified as belonging to the Galendromimini, but it would not fit the description of any of the genera in that tribe. Except for the absence of seta z 3, this species fits the characteristics of Typhlodromus  ( Anthoseius  ), as defined in that same paper.

FEMALE – (1 specimen measured)

Dorsum – Dorsal shield with few reticulations, 320 long and 152 wide at widest level of the proscutum. Setae j 1 18, j 3 26, j 4 16, j 5 21, j 6 24, J 2 24, J 5 10, z 2 27, z 4 27, z 5 20, Z 4 29, Z 5 45, s 4 27, s 6 30, S 2 29, S 4 29, S 5 24, r 3 37, R 1 27. Seta z 3 absent; seta J 5 is sharp­tipped and smooth; seta Z 5 is knob­tipped and serrate; other setae are knob­tipped and smooth.

Peritreme – Extending forward to level between insertions of j 1 and j 3.

Venter – All shields distinct, except the posterior margin of the sternal shield, and smooth. Sternal shield with 3 pairs of setae and 2 pairs of lyrifissures. Distances between ST 1 ­ST 3 66, ST 2 ­ST 2 64, ST 5 ­ST 5 58. With 2 pairs of metapodal shields close together on each side. Ventrianal shield elongate, 112 long, 72 wide at level of ZV 2 and 66 wide at level of anus, with 4 pairs of preanal setae and a pair of small pores mesad and slightly posterior to JV 4. Ventral setae sharp­tipped, except JV 5 which is knob­tipped.

Chelicera – Movable digit 39 long, with 2 teeth; fixed digit 30 long, with 2 teeth.

Spermatheca – Calyx tubular, flaring towards vesicle, 18 long; atrium distinct.

Legs – With knob­tipped macrosetae only on leg IV: Sge IV 22, St IV 29; the numbers of other knob­tipped setae of legs are: leg I – 3 (femur), 2 (genu); leg II – 1 (femur), 1 (genu); leg III – 3 (genu), 3 (tibia), 1 (tarsus); leg IV – 2 (femur), 2 (genu), 3 (tibia), 1 (tarsus); legs I­III without macrosetae. Chaetotaxy of genu II 2 ­(2,2)/ 0­1; genu III 1­2 / 1,2 / 0­1.

MALE ­ Unknown..

TYPE MATERIAL – Holotype female ( ESALQ / USPAbout USP) from Ficus  sp, 3 km north of Lunga­Lunga, Coast Province, Kenya, 28 ­XI­ 89, coll. J. S. Yaninek.

ETYMOLOGY – The epithet cephalochaitosus  refers to the knob­tipped setae presented by this new species.
