Exallomochlus balouchestanensis Moghaddam sp. n.

( Fig. 12 )

Adult female.

Described from 5 Specimens.

DIAGNOSIS. Mounted adult female nearly circular, membranous, 2.60–3.28 mm long and 2.16–2.76 mm wide. Anal lobes moderately developed, each with an apical seta 200–250 µm long on ventral surface, and a wide sclerotized area occupying much of lobe; inner edge of sclerotized area more heavily sclerotized, with a bar-like process. Antennae each 390–450 µm long, usually 8 segmented. Legs well developed; hind trochanter + femur 270–300 µm long, hind tibia + tarsus 250–270 µm long. Claw stout, about 32 µm long. Ratio of lengths of hind tibia + tarsus to hind trochanter + femur 1:1.08–1.11. Ratio of lengths of hind tibia to tarsus 1:1.50–1.84. Translucent pores present on anterior and posterior surfaces of hind coxa and on posterior surface of hind tibia. Cerarii numbering 18 pairs. Anal lobe cerarii each with 2 or 3 stout conical to lanceolate setae, each about 20 µm long, 5 or 6 small, slender setae, plus a concentration of trilocular pores, all situated at posterior end of a lightly sclerotized area occupying most of lobe. C14–C17, each bearing 3 or 5 stout conical to lanceolate setae, and at most 1 small slender setae; C6–C13 each with 1 or 2 setae, without slender setae; and C1–C5 each with 3 or 4 setae. Circulus present, 190–220 µm wide, divided by an intersegmental line. Ostioles well developed, with inner edges of lips sclerotized, each lip with 0–6 setae and 11–14 trilocular pores. Anal ring situated a short distance from apex of body, 100–110 µm long and 90–100 µm wide, bearing 6 setae, each seta 90–100 µm long.

Dorsal setae slender to conical. Anterior setae often of various lengths, many as long as 18 µm, more posterior setae either similar to anterior setae or shorter and conical near midline, each 23 µm long. Trilocular pores evenly distributed. Discoidal pores minute, not pore-like, scattered.

Ventral surface with normal flagellate setae, usually more slender than dorsal setae. Cisanal setae each 100–120 µm long, about same length as anal ring setae or longer, usually displaced onto dorsum posterior to anal ring; obanal setae each about 95–100 µm long. Multilocular disc pores present posterior to vulva and in single or double rows medially across posterior edges of abdominal segments VI and VII; also in a single row on posterior submedial edge of abdominal segment V. Trilocular pores evenly dispersed. Discoidal pores similar to those on dorsum, scattered. Oral collar ducts each narrower than a trilocular pore, with a few across middle of abdominal segments VI and VII, plus a few marginally on abdominal segments VI–VII and submedially on segment V.

MATERIAL EXAMINED.

Holotype adult Ƥ, IRAN. Sistan & Balouchestan: Rask, Firouzabad, on Mangifera indica (Anacardiaceae) , 11.ix.2000, (HMIM).

Paratype adults, IRAN. Same data as Holotype, 4 adult Ƥ (HMIM).

COMMENTS. Exallomochlus balouchestanensis is closely related to E. philippinensis Williams in possessing: (i) normal discoidal pores that are not peg-like, (ii) mid-dorsal setae on abdomen conical to moderately elongate, and (iii) short conical cerarian setae. But E. balouchastanensis differs as follows (character states on E. philippinensis in brackets): (i) the largest specimen 3.28 mm (1.85); (ii) the conical to lanceolate setae of C6−C13 number only 1 or 2 (4−10); (iii) oral collar ducts present on ventral margin of segments VI and VII (absent), and (iv) multilocular disc pores present ventrally on segments V–VII (VI −VII).

ETYMOLOGY. The name is based on the name Balouchestan and the Latin suffix '- ensis ' denoting origin.
