Description

Female (n = 3)

Dorsum ( Figure 1 ) — Dorsal setal pattern 10A:9B (r3 and R1 off shield). Dorsal shield oval smooth, with scattered muscle-marks (sigilla), bearing 6 pairs of small solenostomes, length of dorsal shield (j1-J5) 313 – 352, width (distance between bases of s4) 196 – 221; dorsal setae smooth, except for setae Z4 and Z5 which are faintly serrate, measurements of setae as follows: j1 33 – 38, j3 32 – 39, j4 8 – 9, j5 7 – 8, j6 6 – 7, J2 8 – 9, J5 9 – 10, z2 9 – 12, z4 8 – 12, z5 6 – 7, Z1 9 – 12, Z4 91 – 99, Z5 220 – 251, s4 86 – 96, S2 10 – 12, S4 9 – 11, S5 9 – 10, r3 10 – 16, R1 8 – 9, JV5 50 – 55. Peritreme extending anterior to setae j1 .

Venter ( Figure 2A ) — Ventral setal pattern 14: JV-3: ZV. Sternal shield smooth, with 3 pairs of setae (ST1, ST2, and ST3) and 2 pairs of solenostomes (pst1 and pst2); length (ST1-ST3) 64 – 69, width (distance between setae ST2) 70 – 73; metasternal setae ST4 and a pair of solenostomes (pst3) on metasternal shields. Genital shield smooth; width at level of genital setae (ST5-ST5) 58 – 64. Ventrianal shield vase-shaped, with 3 pairs of preanal setae (JV1, JV2, and ZV2), anal setae (a1, a2, and a3), one pair of small solenostomes closely associated with setae JV2 and situated directly posterior to it. Length of ventrianal shield 102 – 117, width (ZV2-ZV2) 44 – 48, width at level of anal opening 61 – 69. Setae JV4, JV5, ZV1, ZV3, and 4 pairs of solenostomes on integument surrounding ventrianal shield. Seta JV5 smooth, 51 – 60 in length.

Chelicerae ( Figure 2B ) — Fixed digit 29-36 long with 12 teeth and pilus dentilis; movable digit 31 – 33 long with 4 teeth.

Legs ( Figure 2C ) — Length of legs (base of coxae to base of ambulacrum) as follows: leg I 380 – 409; leg II 301 – 315; leg III 300 – 335; leg IV 368 – 424. GeII, GeIII, and GeIV with 7, 7, and 7 setae, respectively. Leg IV with 3 macrosetae, SgeIV 98 – 128, StiIV 75 – 89 and StIV 63 – 70. Leg III also with 3 macrosetae, SgeIII 41 – 46, StiIII 33 – 40 and StIII 30 – 32. Legs II and I with one macroseta each, Sge II 34 – 39 and Sge I 40 – 48.

Spermatheca ( Figure 3 ) — Calyx fundibular, 24- 32 long, atrium wafer-like and nodular major duct long, minor duct not visible.

Male: Unknown.

Remarks

The Turkish specimens actually perfectly fit the redescription of Denmark and Muma (1989). It is only setae s4 which is 4 microns shorter than that in the re-description and setae Z4 which are 10 micron shorter.

This species close resembles A. largoensis (Muma) in general appearance. However, it differs from the latter in having the calyx of the spermatheca fundibular instead of tubular, the atrium waferlike nodular oppose to only nodular ( Collyer 1982, Denmark and Muma 1989) ( Figure 4 ), the preanal solenostomes of the ventrianal shield are posterior to setae JV2 and closely associated with these setae, whereas posteromedially to JV 2 in A. largoenesis ; the movable cheliceral digit bears 4 teeth but 3 in A. largoensis . A. herbicolus can further be distinguished from A. largoensis in that seta Z5 is 220 – 225 long opposed to about 206 in A. largoensis . All these features are present in the Turkish specimens of A herbicolus .
