Typhlodromus (Anthoseius) cephalochaitosus n. sp. ( Fig. 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 z3, 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 j1 18, j3 26, j4 16, j5 21, j6 24, J2 24, J5 10, z2 27, z4 27, z5 20, Z4 29, Z5 45, s4 27, s6 30, S2 29, S4 29, S5 24, r3 37, R1 27. Seta z3 absent; seta J5 is sharp­tipped and smooth; seta Z5 is knob­tipped and serrate; other setae are knob­tipped and smooth.

Peritreme – Extending forward to level between insertions of j1 and j3.

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 ST1­ST3 66, ST2­ST2 64, ST5­ST5 58. With 2 pairs of metapodal shields close together on each side. Ventrianal shield elongate, 112 long, 72 wide at level of ZV2 and 66 wide at level of anus, with 4 pairs of preanal setae and a pair of small pores mesad and slightly posterior to JV4. Ventral setae sharp­tipped, except JV5 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 / USP) from Ficus sp, 3 km north of Lunga­Lunga, Coast Province, Kenya, 28­XI­89, coll. J. S. Yaninek.

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