Zootaxa 5583 (3): 589-596, DOI: 10.11646/zootaxa.5583.3.11, URL: https://doi.org/10.11646/zootaxa.5583.3.11
03EA87ADFF90EE6D5CB1F8E9FC33FE04.taxon	discussion	Bhatti distinguished his new genus solely on the basis that the postocular setae were exceptionally short for a Haplothrips species. Subsequently, in synonymising his species indica with euphorbiae, Bhatti (1979) added as distinguishing states for Ananthakrishnana the sexual dimorphism of the maxillary stylet position, and the unusually reticulate sculpture on the vertex. Sexual dimorphism in the position of maxillary stylets is now known to occur among various unrelated species of Haplothrips (Dang & Mound 2023). Similarly, reduction in length of the postocular setae also occurs in different species of Haplothrips (Mound 2024), including Haplothrips leucanthemi that is widespread across the Holarctic in the flowers of Ox-eye Daisies, Chrysanthemum leucanthemum. The third character state, the presence of sculpture lines on the vertex, also occurs in other species of Haplothrips. As a result, there seems to be no justification for considering euphorbiae as representing a lineage independent from other Haplothrips species, and Ananthakrishnana is here placed into synonymy.	en	Rousse, Pascal, Reynaud, Philippe (2025): Ananthakrishnana syn. n. of Haplothrips, with redescription of H. euphorbiae adult and larva (Thysanoptera).

03EA87ADFF93EE6A5CB1FDCBFB19FC70.taxon	description	Redescription Female macroptera. Body length 1600 – 1840 microns (Fig. 2 A), antenna and legs brown to dark brown, abdomen sometimes lighter than remainder of body; fore wing pale with extreme base and clavus shaded. Head dorsally with transverse wavy striations and reticulate in ocellar area (Fig. 3 A), distinctly protruding between antennal bases, about 1.4 times longer than wide; eye less prolonged ventrally than dorsally; cheeks parallel, slightly tapering towards base; maxillary stylets (Fig. 3 B) retracted beyond mid-length of head and posterior eye margin, 13 – 20 microns distant from each other, maxillary bridge (Fig. 3 B) present (sometimes hardly distinct); posterior ocellus contiguous to eye; post-ocular setae minute. Antenna 8 - segmented (Fig. 3 C), segments III – VII constricted at base, segment II with campaniform sensorium on apical half, segment III with two sense cones, IV with four sense cones, segment III short, 0.8 x as long as IV and about 1.3 times as long as segment VIII, segment IV rounded in shape. Pronotum (Fig. 4 A) with similar transverse and wavy striations, only epimeral seta developed, capitate, anteromarginal and mid-lateral setae no longer than discal setae, notopleural sutures complete, basantra and ferna transverse and large; mesopresternum transverse and eroded medially; mesonotum transversally reticulate with laterally three pairs of campaniform sensilla and four pairs of posterior setae; metanotum (Fig. 4 B) reticulate with a median pair of setae and three pairs of small antero-lateral setae. Fore tarsal tooth present (Fig. 5 B), sometimes reduced to weak lateral protuberance. Fore wing moderately constricted medially, without duplicated cilia on posterior margin; fore wing cilia smooth; all three sub-basal setae short with apex expanded. Pelta broadly triangular and reticulate (Fig. 4 B); tergites transversely striate-reticulate, sculpture stronger laterally and anteriorly; tergites II – VII with two pairs of wing-retaining setae, lateral setae S 1 hyaline, flattened with apex slightly expanded; tergite IX with S 1 blunt and 0.5 times as long as tergite X, S 2 thinner, blunt and 0.7 times as long as S 1; tube with straight sides, 0.5 times as long as head and about twice as long as its basal width. Male macroptera. Body length 1280 – 1320 microns (Fig. 2 B). Similar to female but: maxillary stylets farther apart (30 – 40 microns); fore tarsal claw more distinct, broad and blunt; sternite VIII without pore plate; aedeagus slender and narrowed to apex (Fig. 5 A), total length 40 microns, maximum width 11 microns distance between gonopore and tip of aedeagus 11 microns. Second instar larva. Body length 1100 – 1450 µm (Fig. 5 C). Live specimens red; mounted specimens whitish but head, legs, antennae, prothorax and tip of abdomen light to dark brownish. Head with two lateral and one anterior plates, central oval small plate on frons (10 x 6 µm); antenna 7 - segmented, (175 µm long), segment III 1.70 x longer than wide and tapering basally, segment VII 2.75 x longer than wide; D 1 seta (20 µm) with expanded apice, other setae smaller and acute; maxillary stylets retracted to D 1 seta. Thorax. Dorsal setae with indistinct basal sclerotization; prothorax smooth with two large dorsal plates and seven pairs of setae: D 1, D 6 and D 7 setae strongly expanded, D 2 to D 4 small and acute (D 3 vestigial); D 1 17 – 22 µm, D 6 32 – 40 µm, D 7 25 – 35 µm; pronotal dorsal plates with posterior margins are medially reduced, setae D 1 situated close to their edges; meso- and metanotum with a single sclerite pair reduced to small transversal plates (10 µm) with microseta, second and third sclerites pairs entirely lacking; spiracles of metanotum with about 13 cells, without pore; apical setae on all tibiae pointed. Abdomen. Smooth with some microtrichiae on segments VIII – X; dorsal setae with expanded apex and without basal sclerotization; spiracle of segment II with eight cells, without pore; spiracle of tergite VIII with 11 cells, without pore, and small lateral plates reaching at least D 2 seta but not beyond D 1; tergite IX with D 1 setae long and expanded, D 2 and D 3 very small and acute; sternite IX with D 1 seta long (43 – 55 µm) and pointed, D 2 (27 – 38 µm) expanded; segment X cone-shaped, 1.25 x longer than wide with apical setae pointed, about 1.7 x longer than tube.	en	Rousse, Pascal, Reynaud, Philippe (2025): Ananthakrishnana syn. n. of Haplothrips, with redescription of H. euphorbiae adult and larva (Thysanoptera).
