Sangicoccus reynei Kozár & Konczné Benedicty sp. nov. ( Fig. 4 )

Type material. Holotype adult female, Indonesia, Sulawesi Utara, Dumoga-Bone National Park, 1780 m, Gunung Muajat, Summit area, on rotan palm [ Arecaceae ], 31.v.1985, J.H. Martin, No. 4995, BMNH.

Paratype, adult female, data as for holotype, on separate slide, damaged, with some legs and antennae absent, and therefore only some measurements are given, BMNH

Adult female. Body of slide-mounted specimens, broadly oval, 1.76 mm long, 1.50 mm wide. Antennae each with 3 segments, segment lengths (µm) I 16–21 (18), II 7 (8), III 53 –55 (60), each segment with a few short setae; segment II with sensory pore; apical segment with several apical setae, each 19 (18) µm long, plus a few falcate setae, each 14–21 (18) µm long. Frontal lobes present. Eyes present near ventral margin.

Venter. Labium unsegmented, 46–52 (42) µm long, with minute setae at tip. Legs short and not well developed, lengths in (µm), forecoxae 24 (26), trochanter fused with femur without division 54 (53), tibia 30–33 (27), tarsus 35–37 (35), claw 15 (14). Midcoxae 30 (28), trochanter + femur 50–60 (64), tibia 31 (30), tarsus 35 (36), claw 15. Hindcoxae 40 (36), trochanter + femur 63, tibia 37, tarsus 40, tarsal digitules knobbed, each 21, claw 17, claw digitules 18–23, slightly knobbed. All coxae without spinulae; hindcoxae and femora with several large, irregularly-shaped translucent pores on both sides; each trochanter with 2 sensory pores on each side; claws normal, without stout basal half, with or without denticles. All legs with a few flagellate setae and with a sensory pore on each tarsus. Spiracles each 15–16 (17) µm I diameter, without associated disc pores. Locular disc pores, each 5–7 µm in diameter with 5–10 loculi, sparse in segmental bands medially on abdominal segments VI–VIII and in small submarginal groups. Setae short and hair-like, mostly about 8 µm long. Modified microtubular ducts present submedially. Macrotubular ducts, each 15–35 µm long and 3 µm wide, present in a submedial band on some abdominal segments; each duct with a wide sclerotized area surrounding orifice, and with inner ductule shorter than outer ductule, ending in a circular gland. Oviduct or internal genital organ clearly discernible. Anal lobes with a short suranal seta.

Dorsum. Marginal setae truncate-conical, each 7–12 µm wide and 16–27 (15–26) µm long, present in 11 large groups, more or less equispaced, each on a sclerotised area of derm. Dorsal setae of two main sizes, larger setae spine-like, robust, tapering and bluntly pointed, each 77–90 (77–83) µm long with a striated surface, in 2 longitudinal rows, each with 7 spines on midline; smaller setae much more slender but stiff, each 10–13 (10–15)µm long, sparse in a band between marginal setae and median area with microducts. Some intermediate-sized setae present on head, each 29–33 (29–30) µm long.. Macrotubular ducts absent. Microtubular ducts, each about 5 µm long, 1 µm wide, present in a broad oval area medially associated with largest dorsal spines; and also in rings around bases of all marginal truncate-conical setae. Quinquelocular pores present, scattered submedially and submarginally on all segments. Anal ring 49–51 µm wide, 80 µm long, with a sparse row of pores plus 6 anal ring setae, mostly broken in available 2 specimens. Anal lobes forming a narrow band almost encircling anal ring, probable each lobe with 2 truncate setae on inner margin and 2 long flagellate apical setae, 55 µm long. Cauda present but very narrow, not clearly separated from anal lobes.

Comments. This species is similar to S. morrisoni in possessing marginal groups of disc pores ventrally. It differs from S. morrisoni and S. truncatispinus in lacking the larger, thick, setae on the dorsum just mesad to the groups of marginal truncate setae except on head, and in possessing a medial band of microtubular ducts around the medial longitudinal rows of large spine-like setae.

Etymology. The species is named after A. Reyne who, with his work in the Netherlands, helped to increase our knowledge of scale insects in southern Asia and the Caribbean areas.
