MATERIAL EXAMINED: CEYLON ( SRI LANKA ), Paredeniya , xi. 1940 , E.E. Green coll., 1/5 ad male, deposited at BNHM . DESCRIPTION (as for family description unless otherwise stated): Mounted material: Moderately large, total body length 1.66 – 1.76 mm . Antennae exceptionally long, nearly 2 times total body length, most segments approximately subequal in length (vs. <1.3 times body length for all other species). Body with few setae; lp of triangular shape, each 7–8 µm wide, with mostly 3 loculi, occasionally 4, present on both dorsal surface. Head: Width 285 µm and length 300 µm . Dorsally, with (on each side) about 5 hs of rather variable length ( 20–50 µm ), all flagellate, plus 2 lp and 1 or 2 mcp . Laterally, compound eye about 155 µm long, with about 160 ommatidia. Ocellus 30–40 µm wide. Ventrally, ventral arm extending to midlength of head, fusing with preoral ridge and bifurcated posteriorly; ventral head setae: with (on each side) 8–12 hs plus 1–4 lp + 3 or 4 mcp . Antenna: Length 3.23 mm (ratio of total body length to antennal length 1:1.9). Scape: 94–117 µm long, 63–80 µm wide, each with 6 or 7 short hs + 2 or 3 minute pores ventrally and 4 hs dorsally. Pedicel: 65–85 µm long, 49–57 µm wide; each with 3 fs , 5 or 6 hs , 3 minute pores ventrally. Segments III–IX with proximal segments about 36–43 µm wide, while apical segment only 15–24 µm wide: fs short, those on segment III 28–38 µm long, those on apical segment 25–30 µm long; lengths of segments (µm): III 369–405; IV 433–479; V 423–509; VI 381–520; VII 400–494 and VIII 400–600; approximate number of setae per segment: III–VIII; about 45–70 fs +10–15 hs ; no bristlelike setae detected. Segment IX elongate: 346–412 µm long; with about 80 fs + 1 strong terminal bristle, about 35 µm long + 1 antennal bristle laterally near apex. Thorax: Prothorax: dorsally, pronotum not observable. Posttergites each a small, lightly sclerotized, oval area situated mediolaterally. Pronotal setae: median pronotal setae: 1 hs plus 2 or 3 lp + 2 or 3 smp ; propleural setae not detected; also with a group of posterior propleural setae and pores just anterior to each prealare, extending ventrally and joining antemesospiracular setae: 1 hs , 5–6 lp + 3–5 smp . Ventrally, Prosternum with 1 hs prosternal setae + 1 lp on each side. Mesothorax: Dorsally, prescutum, 97 µm long, 134 µm wide; ridges as for family. Distance between prescutum and scutellum medially 97–117 µm ; with about 2 hs scutal setae: + 15 minute pores medially posterior to prescutum. Scutellum anterior margin rounded and posterior margin straight, 170–181 µm wide, 109–112 µm long, with 2 lp + 3 smp but no setae. Laterally, tegula with 2 or 3 setae. Mesothoracic spiracle: peritreme almost round, width about 30 µm . Ventrally, basisternum 390 µm wide, 180 µm long; with about 10 hs basisternal setae. Metathorax: Dorsally, metapostnotum with 2 metatergal setae. Dorsospiracular setae: 1 hs plus 2 lp . Laterally, metathoracic spiracle peritreme almost round, width 35 µm . Ventrally, sclerotized area with 3–5 hs + 1 lp + some smp on each side; occasionally with 1 hs anterior metasternal seta and 0 or 1 hs posterior metasternal setae. Wings: Forewing length and width unknown because wings damaged, hamulohalteres with 2 hamuli. Legs: Coxae: I: 126–160; II: 129–148; III: 136–146 µm long; coxa III with about 4 setae. Trochanter + femur: I: 603–686; II: 527–597; III: 603–673 µm long; trochanter III with about 5 setae; each trochanter with 4 campaniform on each side; femur III with about 40 setae + 10 smp . Tibiae: I: 882–804; II: 776–805; III: 801–918 µm ; tibia III with a total of about 115 setae + 5 smp ; spurs on ventral surface of distal end of tibia similar to those anteriorly; each distal spur 26–30 µm long. Tarsi: I 187–200; II 184–212; III 194–212 µm long (ratio of length of tibia III to length of tarsus III 1: 0.44); tarsus III with about 30 setae, mainly spurlike; tarsal digitules very short and setose. Claws fairly long and thin, much longer than width of tarsus (each tarsus about 25 µm wide), held at a distinct angle to tarsus, each with a small denticle; length: III 60 µm ; claw digitules both short and setose. Abdomen: Segments I–VII: Tubular ducts present in as a band across tergite VII, each duct 8 µm wide, 20 µm deep, with a slightly spirally ridged inner surface. Dorsal abdominal setae and pores (totals): segments I–V: 4 extremely long hs ( 80–100 µm ); VI: 4 extremely long hs + some lp , group fusing with pleurites; VII: about 20 hs and 20–25 tubular ducts. Pleural setae: dorso- and ventropleural setae combined on each side: I– VII: 3 or 4 hs + 12–20 lp + 15–25 smp , most setae about 50–60 µm long. Ventral abdominal setae fleshy and shorter than dorsal abdominal setae, each 35–40 µm long (totals): I 8 fs ; II 8 or 9 setae; III–VI 10–12 fs ; VII 6–8 fs ; lp absent on all sternites. Abdominal spiracle at least present from segment III to VII each peritreme about 10 µm wide. Segment VIII: tergite with 1 or 2 pairs of hs dorsal abdominal setae, plus about 40 small locular pores and many smp ; sternite with about 10 ventral abdominal setae but no pores; margin rounded, with 2–4 hs pleural setae, 3 or 4 lp + 2–4 smp . Genital segment: Anus large ( 32 µm wide); with 1 or 2 hs on tergite IX; sternite IX without a median ridge, with 3 or 4 setae. Penial sheath as broad as posterior margin of abdominal segment VIII, length without segment IX 190 µm , with segment IX 243 µm ; greatest width 140 µm ; ventrally and laterally with a group of 20 hs on each side of anterior end of penial sheath. Aedeagus about 170–190 µm . COMMENTS: The adult male of I. insignis is unique in having extremely long appendages, particularly the antennae, almost twice as long as the body length, as compared to other genera; a pair of very long setae are present on each tergite, loculate pores of 3 or 4 loculi are on the pleurites and overlapping on tergites but absent on sternites, and sternite VIII does not have a median ridge (similar to Orthezia , but in constrast to Graminorthezia and Praelongorthezia ).
