Benedictycoccina ornata ( HAMBLETON, 1946 a)

( Fig. 4 )

Comment: This species differs from other members of the genus by the absence of multilocular pores, and by the presence of wide bands and groups of trilocular pores on the abdomen.

Distribution: Trinidad ( Fig. 1 ).

( Fig. 5 )

Type material: The holotype female, in middle of the slide, Tanzania , 1987 (coll. S. MAHUNKA), No. 3402 (103). Six paratype females, on five slides, from the same collection as the holotype, No. 3402 (103) (two slides), and No. 560 (three slides). Types are deposited in the Hungarian Natural History Museum (Budapest, Hungary) .

Description: Body elongate oval. Slide-mounted specimen ( Fig. 5 ) 0.71 mm long and 0.26 mm wide. Antenna 6 segmented, the length of the segments: 1st – 29 µm, 2nd – 12 µm, 3rd – 15 µm, fourth – 14 µm, fifth – 12 µm, sixth 29 µm long. There is one sensory pore on the 2nd segment. The 3rd segment is almost parallel-sided. The apical segment has four falcate sensory setae. On the fifth segment one, strong 13 µm long, blunt seta. Most segments of the antenna have a few hair-like setae; the longest one is 19 µm. Eyes well visible. Anal lobe is slightly developed with three long, hair-like setae.

Venter. Labium appears two-segmented, 51 µm long. Stylet loop four times longer than labium. Cephalic plate not visible. Legs robust: coxa of anterior legs 25 µm, trochanter 24 µm, femur 55 µm, tibia 33 µm, tarsus 31 µm, and claw 18 µm. Coxa of middle legs 27 µm, trochanter 22 µm, femur 45 µm, tibia 35 µm, tarsus 26 µm, and claw 17 µm long. Coxa of posterior legs 29 µm, trochanter 23 µm, femur 50 µm, tibia 45 µm, tarsus 38 µm, and claw 20 µm, tarsal digitules absent, claw digitules short, as long as claw, blunt. Trochanter with two pores on each side. Claw without denticle. Legs with few hair-like setae, tibia and tarsus with 11 µm long setae. On the ventral segments few tritubular ducts present on margin surrounded by trilocular pores. Some multilocular pores present around of vulva, 6 µm in diameter. The diameter of anterior spiracles 9 µm. Venter with a small number of scattered hair-like setae. Two circuli present, 24 µm in diameter. Tubular ducts absent. Internal genitalia as long as width of one segment; close to distal part, vagina is enlarged bearing vaginal glands.

Dorsum. Ostioles present, not sclerotized. Multilocular pores absent. Anal ring oval, 55 µm wide and 48 µm long. Anal ring with six, 51 µm long hair-like setae. Anal ring pores (cells) typical, few, with spicules on pores of outer row. Tritubular ducts of one size, in small number on last segments, and scattered on thorax, the tube 4 µm long and 3 µm wide. Tubular ducts absent. Hair-like setae 11 µm long, trilocular pores scattered on the dorsum. Bilocular pores present on all segments.

Distribution: Tanzania ( Fig. 1 ).

Etymology. The species is named after the country of origin.

Affinities: This species differs from all others in the genus, by having multilocular pores only on the last ventral abdominal segments.
