description: Neogreenia ficus Zheng & Wu, sp. n.
Material examined. Holotype: Adult ♀, CHINA: Hainan Prov., / Baoting County, Baocheng Town, / 18°63′98″N, 109º70′01″E, / on Ficus microcarpa (Moraceae), / 2 February 2023, / Jiangtao Zhang leg. Mounted singly on a slide (BFUC).
Paratypes: CHINA: same data as holotype, 3 ♀♀, mounted singly on 3 slides (BFUC).
Etymology. The species epithet is derived from the name of the host plant genus, Ficus, and is a noun in apposition.

Most setae on antennae hair-like, each 23–75 μm long; scape and pedicel with setae scattered; pedicel with 3 circular sensory pores dorsally and 1–3 coeloconic sensilla ventrally plus 1 sensory seta; remaining segments each with a ring of hair-like setae except apical segment; segments IV–IX each with a pair of sensory setae, each 32–43 μm long, sometimes segments IV and V each with coeloconic sensillum; apical segment with 10 or 11 sensory setae and 6 or 7 hair-like setae. Eyes each with margin sclerotized and centre membranous, 38–63 μm wide, each situated posterolaterad of scape. Mouthparts present (Fig. 4C): labium 2 segmented, 110–138 μm long and 88–113 μm wide, segment I 23–28 μm long, with a pair of short setae (each 8–10 μm long) on each side; segment II 83–108 μm long, sclerotized and slender, with 4 hair-like apical setae (each 25–28 μm long) on each side. Clypeolabral shield longer than labium, 375–670 μm long; stylets present. Thoracic spiracles (Fig. 4D) each with opening 30–48 μm in diameter, a sclerotized bar and a group of 28–57 sieve-like disc-pores at inner end of atrium. Abdominal spiracles numbering 8 pairs: anterior 6 pairs (Fig. 4E) developed, each with opening 25–35 μm in diameter, and a group of 11–27 sieve-like disc-pores within atrium; posteriormost 2 pairs (Fig. 4F) small and tube-like, each with opening unsclerotized, about 10 μm in diameter, and without pores within atrium. Legs (Fig. 4G) developed, lengths (in μm): foreleg: entire length 700–1,550; coxa 80–160; trochanter + femur 250–560; tibia 240–470; tarsus 125–240, and claw 38–54; middle leg: entire length 780–1,720; coxa 90–190; trochanter + femur 250–455; tibia 260–430; tarsus 140–225, and claw 38–60; hind leg: entire length 775–1,660; coxa 143–350; trochanter + femur 252–610; tibia 252–610; tarsus 133–275, and claw 40–68. Hind leg trochanter + femur 0.63–0.72 times as long as tibia + tarsus; tibia 1.93–1.96 times as long as tarsus; coxa with basal setae each 20–23 μm long. Trochanters each bearing 3 sensory pores on each surface plus a long hair-like seta, 140–215 μm long; second longest seta 40–85 μm long; remaining hair-like setae each 15–38 μm long. Femora each with setae 23–28 μm long. Each tibia with a tuft of long and capitate digitules (Fig. 4H), each 43–55 μm long; remaining setae short, each about 15 μm long. Tarsi curved, each with few setae on distal half, each seta 15–28 μm long. Claws (Fig. 4I) each with 2 or 3 (mostly 2) small denticles and a pair of pointed digitules (each 25–28 μm long) shorter than claw. Vulva situated on venter of abdominal segment VIII, with opening longitudinal and slit-like, 58–95 μm long. Anal opening located dorsally on medial area of abdominal segment VIII, simple, with semicircular sclerotization, without pores or setae, 40–75 μm wide.
Dorsum. With disc-pores of 3 types: (i) large simple pores (Fig. 4J), each 11–12 μm in diameter, with sclerotized rim; present in small submarginal groups on head and thorax, and forming roughly transverse bands across anterior and posterior margins of each abdominal segment except for posteriormost 2 segments and posterior margin of segment VI; (ii) compound multilocular disc-pores (Fig. 4K) each 10–11 μm in diameter, with 3 subcentral loculi and an outer ring of 10–12 indistinct peripheral loculi, few, scattered on body; and (iii) bilocular compound multilocular disc-pores (Fig. 4L), each about 10 μm wide, with 2 subcentral loculi and a ring of indistinct peripheral loculi, forming broad transverse bands across each segment. Setae of only 1 type, hair-like, each 20–58 μm long, forming transverse band across each segment.
Venter. With disc-pores of 6 types: (i) large simple pores (Fig. 4J), same size and structure as on dorsum, present on medial area of head, near each coxa, and forming roughly transverse bands submedially and medially across abdominal segments except for last segment; (ii) compound multilocular disc-pores (Fig. 4K), same structure, size and distribution as on dorsum; also a few with 4 loculi or irregularly distributed subcentral loculi (Fig. 4M), present around each thoracic and abdominal spiracle; (iii) bilocular compound multilocular disc-pores (Fig. 4L), structure, size and distribution same as on dorsum but with more pores on posterior end; (iv) thick-rimmed simple pores (Fig. 4N) each about 5 μm in diameter, numerous, scattered on abdominal segment VIII; (v) sieve-like disc-pores, each about 7.5 μm in diameter, forming group in atrium of each thoracic spiracle and anterior 6 pairs of abdominal spiracles; and (vi) thin-rimmed simple pores (Fig. 4O), each about 5 μm in diameter; 6–8 pores present within group of large simple pores on prothorax. Setae of 2 types: (i) hair-like setae, each 20–170 μm long; short setae present on submargin and margin of each segment and scattered on abdominal segment VIII, longer setae present medially except on posteriormost segment; and (ii) short conical spine-like setae (Fig. 4P) with sclerotized basal sockets, each about 5 μm long; 3–7 spines present around each thoracic spiracle, and about 3 present around each of anterior 6 pairs of abdominal spiracles.
Remarks. The adult female of Neogreenia ficus is closest to that of N. sophorica in sharing the following character states: (i) bilocular compound multilocular disc-pores present over entire body; and (ii) claws mostly each with 2 small denticles. Adult female N. ficus differ from those of N. sophorica by having (character states of N. sophorica in parentheses): (i) tibia with capitate digitules (tibia with pointed digitules), and (ii) large simple pores absent from posteriormost abdominal segment (large simple pores present on posteriormost abdominal segment).
