Hambletonia bitubularis KOZÁR et FOLDI sp. n.

( Fig. 14 )

Type material: The holotype female, in center of the slide (marked), one paratype female and an immature on the same slide, Peru, Oxypampa, 01.11.2000 (coll. G. SZÖVÉNYI), No. 6189, from moss. Three paratype females, on one slide, from the same collection as the holotype. One paratype female, Peru (coll. G. SZÖVÉNYI, YC 2400) No. 6190. One paratype female, Peru (coll. G. SZÖVÉNYI, YC 2500) No. 6194. Holotype deposited in the Hungarian Natural History Museum (Budapest, Hungary), paratypes deposited in Collection of Plant Protection Institute, Hungarian Academy of Sciences (Budapest, Hungary).

Description: Body elongate oval. Slide-mounted specimen ( Fig. 14 ) 1.13 mm long and 0.67 mm wide. Antenna 5 segmented, the length of the segments: 1st – 53 µm, 2nd – 22 µm, 3rd – 38 µm, fourth – 24 µm, fifth – 76 µm long. One sensory pore on 2nd segment of the antenna. The 3rd segment is almost parallel sided. The apical segment has four falcate sensory setae, and one narrow, 38 µm long, blunt seta. Most segments of the antenna have a few hair-like setae, the longest one is 43 µm. Eyes well visible. Anal lobe slightly developed with three long, hair-like setae.

Venter. Labium appears two-segmented, 101 µm long. Stylet loop twice longer than labium. Cephalic plate visible. Legs robust: coxa of anterior legs 74 µm, trochanter 48 µm, femur 122 µm, tibia 84 µm, tarsus 84 µm, and claw 36 µm. Coxa of middle legs 70 µm, trochanter 55 µm, femur 127 µm, tibia 84 µm, tarsus 82 µm, and claw 34 µm long. Coxa of posterior legs 84 µm, trochanter 62 µm, femur 139 µm, tibia 101 µm and tarsus 89 µm, and claw 36 µm, tarsal digitules absent, claw digitules short, 9 µm long. Trochanter with two pores on each side. Claw without denticle. Legs with few hair-like setae, tibia and tarsus with 25 µm long setae. On segments few bitubular ducts present on margin, the tubes 5 µm in diameter, and 10 µm long. Instead of multilocular pores some five locular pores present on the last segment. The diameter of anterior spiracles 17 µm. With a small number of scattered hair-like setae. Circulus absent. Tubular ducts absent. Trilocular pores distributed on all segments. On median area of abdominal segments, two groups of unique trilocular pores, 4 µm in diameter.

Also one more unique trilocular pore group on the head. Internal genitalia have an unusual structure and as long as width of one segment. Internal genitalia with two lateral extensions appearing to be the well developed ductules of vaginal glands, situated at its middle part of vagina; between these glands and vulva, vagina is strongly enlarged.

Dorsum. Ostioles sclerotized. Multilocular pores absent. Anal ring oval, 50 µm wide and 43 µm long. Anal ring with six, 74 µm long hair-like setae. Anal ring pores (cells) typical, few, with spicules on pores of outer row. Bitubular ducts of one size, 4–6 on each segment, tubes 5 µm in diameter, 10 µm long. Tubular ducts absent. Hair-like setae 22 µm long, trilocular pores 3 µm wide, scattered on the dorsum, with a special structure, three central pores surrounded by nine small pores.

Distribution: Peru ( Fig. 1 ).

Etymology. The species is named after the presence of bitubular pores.
