03C387A4036FFFFCCA922E5DFA708C18.taxon	diagnosis	Diagnosis. Medium-sized Ceylonosticta, belonging to C. mojca group of species, closely related to C. mirifica sp. nov., described below. Both sexes are characterised by remarkable dorsal processes on the anterior margin of the anterior lobe of the prothorax, which are very long and curved backwards over the prothorax, markedly exceeding its posterior margin. Middle lobe of prothorax of both sexes bluish white, not brown as in C. mojca and C. tropica. In C. subtropica the prothorax processes are much shorter, while in C. mirifica sp. nov. these are curved upward, and not exceeding the posterior margin of the prothorax. With C. mojca and C. mirifica sp. nov., it shares the totally reduced inferior anal appendages of males. Superior anal appendages of C. inferioreducta sp. nov. and C. mirifica sp. nov. are clearly different. In C. inferioreducta sp. nov. they have a narrow base, which in dorsal view does not reach posterodorsal prolongation of the last abdominal segment medially on each side and a tuft of long medially directed setae reaching middle of the superior anal appendage.	en	Tol, Van (2016): Taxonomy and molecular phylogeny of the Platystictidae of Sri Lanka (Insecta: Odonata).

03C387A4036AFFFECA922CC6FD6C8F94.taxon	diagnosis	Differential diagnosis. Medium-sized Ceylonosticta, belonging to C. mojca group of species. Closely related to C. inferioreducta sp. nov., with which it shares remarkable long dorsal processes on the anterior lobe of prothorax, bluish-white middle lobe of prothorax and totally reduced inferior anal appendages of males. In C. mirifica sp. nov., however, the prothorax processes are curved upwards and do not markedly exceed posterior margin of prothorax. Superior anal appendages of males have broad base, reaching posterodorsal prolongation of the last abdominal segment medially and tuft of long caudally directed setae limited to the broad base of the appendages. From C. mojca and C. tropica it is distinguished by the brown middle lobe of the prothorax and much shorter prothorax processes of those species. The prothoracic processes are also useful for separation from C. subtropica, in which the inferior anal appendages of males are not reduced.	en	Tol, Van (2016): Taxonomy and molecular phylogeny of the Platystictidae of Sri Lanka (Insecta: Odonata).

03C387A4036AFFFECA922CC6FD6C8F94.taxon	discussion	Remarks. Coloration in life. — Eyes of males in life bluish grey dorsally, with broad median rusty brown band and yellowish ventral portions (Fig. 140). Middle lobe of prothorax bluish in mature males, elevated margin of anterior lobe with processes brownish grey. Sky-blue lateral stripe on metepisternum stretches well beyond spiracle. Molecular analysis. — The holotype male was collected and stored in alcohol, and two legs in alcohol were deposited at RMNH where molecular analyses were performed. Habitat. — Animals were found and photographed in a small seepage on a densely wooded slope, just above the local road from Uwella to Ratnapura in Sabaragamuwa Province. A fragment of primary forest still exists at the spot; however, the wider surroundings are under heavy agricultural pressure, and almost all forest has been converted to tea plantations. Conservation. — The species is known only from type locality and is probably quite rare. Due to the paucity of appropriate habitats in wider surroundings of Balangoda, the species is highly threatened and should be considered as a high priority for conservation monitoring and action.

Slightly bigger and more robust than C. brincki, synthorax in mature individuals of both sexes brown above the lateral blue thoracic stripe and golden yellow below, while in C. brincki sides of thorax brown above and below the lateral blue thoracic stripe. Males are distinguished at a glance from C. brincki based on the shape and equal length of superior and inferior anal appendages. Inferiors are apically prolonged, with conspicuous subapical inward and slightly caudally directed spine, very similar to C. austeni but longer and more conical. A somewhat similar subapical spine also present in C. digna, but much shorter inferiors of the latter separate these two species at a glance. In C. brincki the conspicuous subapical inwardly directed spine is lacking. Apart from lateral thoracic coloration, female of C. venusta sp. nov. is distinguished from C. brincki by posterior margin of posterior prothoracic lobe not evenly rounded but with marked rounded dorsolateral expansions and by the dorsal sky-blue coloration of last abdominal segments obscured proximally.	en	Tol, Van (2016): Taxonomy and molecular phylogeny of the Platystictidae of Sri Lanka (Insecta: Odonata).

03C387A40365FFF6CA922EB8FB3E8D4C.taxon	discussion	Remarks. Coloration in life. — Eyes of both sexes in life bluish grey dorsally, with broad median rusty-brown band and light ochreous ventral portions. Middle lobe of prothorax sky blue on dorsum, posterior portion of posterior prothoracic lobe dark brownish, largely obscuring blue colour in some animals. Dorsum of synthorax dark brown, antealar triangles brown, posterior alar processes with a small patch of blue. Lateral blue band framed narrowly with dark brown also below as far as metapleural suture, but metepimeron of contrasting golden-yellow coloration. Abdomen very dark brown on dorsum, except for ochreous basal portions in males and blue basal portions in females. In the latter, the blue coloration on S 9 as well as on intersegmental membrane between S 9 and S 8 is markedly obscured with very dark brown proximally (Figs. 151 – 153). Molecular analysis. — Type material was collected and stored in alcohol, and two legs of paratype male in alcohol were deposited at RMNH where molecular analyses were performed. Habitat. — C. venusta sp. nov. has been observed and photographed at only a few localities in the wider surroundings of Rambodde in central part of Sri Lanka. Its distribution is obviously limited to higher altitudes between 700 and 1,000 metres, although it has also been recorded as high as over 1,600 metres. It also seems to be very seasonal, as all records so far originate exclusively from July. Searches for the species in November have been unsuccessful at the known localities. Conservation. — Preserved natural forest habitats with small streams and seepages in the central mountainous part of Sri Lanka are very scarce and highly fragmented. Water from them is extracted for consumption and irrigation, and remaining forest patches are converted to home gardens and domestic tea plantations. Therefore, the endemic C. venusta sp. nov. is globally threatened, and it definitely deserves immediate conservation attention, together with the majority of its endemic relatives.

03C387A40358FFC1CA922E6DFEC38FF9.taxon	diagnosis	Diagnosis. Large Platysticta, closely allied to P. apicalis. With the latter species it shares the white median lobe of the prothorax and is thus easily separated from its other two congeners, P. serendibica sp. nov., described below, and P. maculata. Males have the posterior parts of the inferior anal appendages moderately curved, with a shallow notch before their upturned point and not distinctly hook-shaped, with a deep notch before their upturned point, like in P. apicalis. In females of P. secreta sp. nov. the elevated and thickened anterior lobe of the prothorax is evenly rounded, while in P. apicalis it is medially compressed posteriorly, slightly convex and with small notch medially. In both sexes, S 4 – 6 of abdomen show characteristic pale rectangular dorsolateral basal markings on each side, prolonged and thinned posteriorly along the ventral side. These basal markings are triangular and smaller in P. apicalis. Females of both species are further distinguished by the dorsal coloration of the last abdominal segments, which are uniformly sky blue in P. secreta sp. nov., while in P. apicalis S 9 is sky blue dorsally with a black longitudinal middorsal stripe. Wings of P. secreta sp. nov. are tipped dark on apices of mature adults of both sexes. Females can be distinguished from all other Platysticta species by this feature.	en	Tol, Van (2016): Taxonomy and molecular phylogeny of the Platystictidae of Sri Lanka (Insecta: Odonata).

Y vein shortly stalked. Number of cells between Arc and place where CuP meets hind margin of hindwing 12. Vein R 3 originates in left forewing at the level of Px 7 and in hindwings at the level of Px 6. In other paratypes the nodal index ranges from 18 ½ to 21 ½ Px in forewings and from 16 ½ to 20 ½ Px in hindwings. Second female paratype in forewings with 18 ½ and 18 and in hindwings with 16 ½ and 17 Px. Apices of wings tipped dark brown in female paratype and all male paratypes, except in two males from Gurulupotha, which are evidently juvenile. Coloration in life. Eyes of both sexes in life black, with contrasting whitish-grey posteroventral portions. Ground colour of synthorax black, with slight metallic shine on dorsum. Lateral blue band and light-coloured portion of metepimeron bluish white. Dorsum of last abdominal segments sky blue in both sexes. (Figs. 170 – 171). Habitat. — As far as habitat and distribution is concerned, P. secreta sp. nov. is peculiar and distinct from its congeners in inhabiting much drier eastern parts of the island. Here the appropriate habitats, like smaller shaded streams and seepages along rivulets in forest or at least in a forested corridor, are rather scarce. The known populations of P. secreta sp. nov. are widely scattered. Adults can be found from March to August, so its flight season appears to be rather long. Most of the records originate from lower altitudes at up to 300 metres, and an old record from Madulsima at over 1,300 metres might just be due to inexact labelling. Conservation. — Despite the fact that eastern parts of Sri Lanka are far less densely populated, the rather dry climate results in high pressure on flowing water for irrigation and domestic use. Consequently, and due to its small range, this new endemic Platysticta is globally threatened, and its habitats deserve special conservation attention.	en	Tol, Van (2016): Taxonomy and molecular phylogeny of the Platystictidae of Sri Lanka (Insecta: Odonata).

03C387A40354FFC6CA9228FFFD218E7A.taxon	etymology	Etymology. The species epithet is a latinized adjective relating to Sri Lanka, after the old Arabic name Serendib for the island of Sri Lanka.	en	Tol, Van (2016): Taxonomy and molecular phylogeny of the Platystictidae of Sri Lanka (Insecta: Odonata).

03C387A40354FFC6CA9228FFFD218E7A.taxon	diagnosis	Diagnosis. Another large Platysticta, allied to P. maculata, with coloration generally similar to other species of the genus. Dorsum of median lobe of prothorax bicoloured white and black; based on this character it is easily separated from P. ap i c a l i s and P. secreta sp. nov., in which the median lobe of the prothorax is completely white. Anterior lobe of prothorax black in both sexes, while in P. maculata it is white or has some black only medially. Conspicuous paired bulges of the median prothoracic lobe are bluntly conical, with tips slightly pointed medially and coloured to different degree with white and black, while in P. macul ata the paired bulges are more evenly rounded and mostly black on dorsum. In males, the tips of the inferior anal appendages are not turned inwards, as in P. maculata. In females of P. serendibica sp. nov., S 9 is predominantly sky blue dorsally, while in P. maculata the blue colour on the dorsum of S 9 is largely obscured by black. Furthermore, apices of wings of both sexes of P. maculata are consistently clear, while the wings of P. serendibica sp. nov. are tipped dark brown in mature males.	en	Tol, Van (2016): Taxonomy and molecular phylogeny of the Platystictidae of Sri Lanka (Insecta: Odonata).

Number of cells between Arc and place where CuP meets hind margin of hindwing 12. Pterostigma brown, encircled by very thin lighter line and surrounded by thick dark brown veins, approximately two times wider than high. Its proximal side oblique, distal side slightly conical in middle due to distal supplementary vein arising at this point, except for left forewing in which its distal side is slightly convex. Abdomen. — Slender, long, ground colour dark brown dorsally, ventrolaterally and ventrally. S 1 with basal triangular lateral ochreous patch pointed posteriorly, same on S 2 in which light triangular light coloration reaches segment end. S 4 − S 7 with ochreous ventrolateral markings broader basally. Dorsum of S 8 – 10 light blue, marking on S 8 rounded proximally, nearly reaching segment base (Fig. 126). Anal appendages dark brown. Superiors twice as long as inferiors and 2.5 length of S 10. In dorsal view superiors narrow and almost straight, obliquely pointed towards middle, with apices touching at end. Laterally flattened, markedly constricted in middle, with broadened distal halves. Inner side of these broader apical parts shallowly hollowed, dorsally with blunt rounded protuberance, situated in middle of distal third of the appendage. Inferiors with strong base, which bears small median projection on dorsum, then narrowed, flattened and twisted inwards, with obliquely pointed tips gently curved upside (Figs. 126 – 127). Measurements [in mm]. Ƌ — head width: 5.08; abdomen length: 48.3; fore- and hindwing length: 35.3, 35.2; fore- and hindwing pterostigma length: 1.75, 1.85; superior appendages: 1.11. Description of paratype female [dried specimen, Lankaberiya Estate]. General habitus very similar to male (Fig. 128). Venation similar to male. Apices of wings clear. Left forewings with 19 and right forewings with 20 Px, left hindwings with 18 and right hindwing with 17 ½ Px. Vein R 3 originates in left forewing at the level of Px 6, between Px 4 and Px 5 in right forewing and slightly proximally to level of Px 5 in hindwings. Y vein shortly stalked. CuP reaching hind margin of forewings approximately at level of Px 6. Anterior lobe of prothorax black, anterior margin slightly elevated, evenly rounded and thickened, posterior portion broadened medially and pressed posteriorly, with rounded notch in middle. Median lobe whitish ventrolaterally but paired bluntly conical bulges on each side of middle gradually dark brown and black in the deep depression in-between. Posterior margin of black posterior prothoracic lobe only slightly upturned posteriorly. Posterior lobe narrow laterally, abruptly broadened and rounded across dorsum (Fig. 129). Vertex of synthorax black, rest of thorax also with black ground colour. Lateral stripe on mesepimeron and two thirds of metepimeron creamy white. Dorsum of S 10 of abdomen light blue, as is intersegmental membrane between S 9 and S 8. S 9 also blue on dorsum, but rounded off and narrowly obscured by black basally. Cerci dark brown. Ovipositor and styli reaching tip of cerci (Fig. 130). Measurements [in mm]. ♀ — head width: 5,5; abdomen length: 40.8; fore- and hindwing length: 33.2, 32.9; fore- and hindwing pterostigma length: 1.7, 1.83; ovipositor: 3.8.	en	Tol, Van (2016): Taxonomy and molecular phylogeny of the Platystictidae of Sri Lanka (Insecta: Odonata).

03C387A40354FFC6CA9228FFFD218E7A.taxon	discussion	Remarks. Variation in paratypes. Wings of paratype male from Kanneliya depicted in Fig. 131. Left forewings with 20 and right forewings with 20 ½ Px, hindwings with 18 ½ and 19 Px. Vein R 3 originates in all wings at the level of Px 5. Apices of wings enfumed dark brown one cell proximal of level of proximal side of pterostigma, proximally with clear centres of cells. In other paratypes the nodal index ranges from 18 ½ to 21 ½ Px in forewings and from 16 ½ to 20 ½ Px in hindwings. Second female paratype in forewings with 18 ½ and 18 and in hindwings with 16 ½ and 17 Px. Apices of wings clear in juvenile female paratype from Sinharaja. In male paratypes from Sinharaja and Tunmodera apices of wings enfumed dark brown slightly proximal of the level of proximal side of pterostigma, while in juvenile paratype males from Lankaberiya-dola, Lankaberiya Estate and Sooriyakanda apices of wings are clear, with pterostigma of lighter brown colour. In all paratypes the anterior and posterior lobe of prothorax are consistently black. Coloration of the middle lobe is subject to variation, but in most cases the bluntly conical bulges are white laterally, while its inner sides, sometimes to the top and even over, the median portion between them and posterior part of middle lobe are black. Coloration in life. Eyes of both sexes in life black, with contrasting whitish-grey posteroventral portions. Ground colour of synthorax black. Lateral stripe white, only slightly bluish. Dorsum of last abdominal segments sky blue in both sexes, occasionally the blue coloration obscured proximally on S 9 in females (Figs. 172 − 173). Habitat. — As it is evident from the number of known localities and from the distribution map, P. serendibica sp. nov. seems to be the most common endemic representative of its genus in Sri Lanka. It is distributed in central and southwestern parts of the island, predominantly in lowlands but also up to 1,000 metres in the hills. The adults are on the wing between March and October. It inhabits small streams, often with tiny waterfalls which are at least partly overgrown with corridor of natural vegetation and at least partly shaded. Apart of such partly degraded habitats it also favours streams and trickles in secondary and primary forest patches. Conservation. — Its habitats are under heavy pressure and have vanished at an alarming rate in the last few decades. At most places the populations of P. serendibica sp. nov. appear to be small; however, due to its relatively large range and considerable number of localities it is here evaluated in the non-acute category of near threatened.	en	Tol, Van (2016): Taxonomy and molecular phylogeny of the Platystictidae of Sri Lanka (Insecta: Odonata).

03C387A40332FFA4CA922A99FE708FB5.taxon	description	Description. Large damselflies, with general characteristics of the family Platystictidae. Thorax dark brown to brick red on dorsum and sides, changing to golden yellow lower on sides and pale yellow beneath. In females only, thorax marked with narrow azure blue antehumeral stripes, convex inward and not extending to upper part of thorax, a second light blue stripe on mesepimeron. Anterior lobe of prothorax white in both sexes, only slightly brown distally. Paired bulges of median prothoracic lobe evenly rounded, posterior margin of posterior prothoracic lobe gently and evenly upturned, with a thickened dark brown margin. Abdomen dark brown to black dorsally, with azure blue markings on dorsum of S 8 and S 9 in male and with a large oval pale blue lateral spot on each side of S 9 in female. Superior anal appendages of male broad at base, constricted at about the middle, with a robust obtuse spine dorsally on inner side, then broadened and somewhat spatulate in apical half, which is curled down and hollowed out. Inferior anal appendages nearly as long as superior pair, broad at base, then tapered as far as apex, which ends in an obtuse inward turned point. Terminal segment of genital ligula divided into a pair of horns apically, with cleft between them wide and straight. Ligula widened at base of horns. Horns short, less than half length of segment, ending in a short bifid structure. Wings closed when at rest, long, narrow, hyaline to palely enfumed in older animals and females, but never with distinct dark coloured apices. Forewings with 17 − 21 Px and hindwings with 16 ½ − 19 Px. Two Ax crossveins and one pcv vein. Y vein shortly stalked. Discoidal cell elongate, with costal border about four times as long as proximal border. Arculus distal to Ax 2, R 4 + 5 well proximal to subnodus. Vein IR 3 markedly zigzagged in middle of wings, separates from R 4 + 5 at level of first crossvein distal to arculus. Vein R 3 originates in proximal half of wing at level of Px 4 − 5. Vein IR 2 also markedly zigzagged. CuP reaching hind margin of forewing at level between Px 4 − 5, in hindwing approximately at level of Px 5 − 6. Number of cells between Arc and place where CuP meets hind margin of hindwing 9 − 10 in forewing and 11 − 12 in hindwing. Pterostigma dark red to blackish in colour, framed finely in light yellow and with heavy black veins, covering more than one cell.	en	Tol, Van (2016): Taxonomy and molecular phylogeny of the Platystictidae of Sri Lanka (Insecta: Odonata).
