523DB050FFE9FFDBFF2CFF54FE574333.taxon	diagnosis	Diagnosis. This species belongs to the Drepanosticta moorei group. It differs from D. moorei van Tol & Müller by the absence of elongated anterior lobe processes of the prothorax, and from D. luzonica van Tol by the very broad posterior lobe of the prothorax and its smaller size.	en	Villanueva, Reagan Joseph T., Schorr, Martin (2011): Two new damselfly species from Polillo Island, Philippines (Odonata: Platystictidae).

523DB050FFEAFFDAFF2CFE3EFD7143F8.taxon	diagnosis	Diagnosis. The posterior lobe with broadly rounded lateral portion places this species as most similar to S. viticula van Tol, 2005. It differs from that species in having a simpler paraproct which is broad basally and distally flattened, its tip acutely curved anterodorsad.	en	Villanueva, Reagan Joseph T., Schorr, Martin (2011): Two new damselfly species from Polillo Island, Philippines (Odonata: Platystictidae).

523DB050FFEAFFDAFF2CFE3EFD7143F8.taxon	etymology	Etymology. Named after Dr. Jan van Tol, Leiden, Netherlands who published the preliminary description of this species. He established the genus of the present species and contributed several significant papers including description of several dozen new species of the family from the oriental region.	en	Villanueva, Reagan Joseph T., Schorr, Martin (2011): Two new damselfly species from Polillo Island, Philippines (Odonata: Platystictidae).

523DB050FFEAFFDAFF2CFE3EFD7143F8.taxon	description	Description of male holotype. Head: Labium and mandible pale with brownish variegated specks more distinct at distal portion. Labrum, anteclypeus, and genae bluish white. Rest of head black except for brownish antennae. Transverse occipital carina distinct but without lateral extremities. Thorax: Prothorax pale except for brownish lateral lobes and black paired circular spot at medial portion of posterior lobe. Lateral portion of anterior lobe slightly elongate, not reaching middle portion of median lobe. Posterior lobe (Fig. 3) collar-like with lateral portion produced into a smoothly rounded lateral projection. Synthorax mostly pale except for mesepisternum with large greenish patch covering entire dorsum, although not reaching anterior and lateral margins. Humeral suture with narrow black humeral stripe, a darkened streak at the anterior margin of mesepimeron. Metepisternum with rectangular blackish median patch and another vague circular spot distal to it, broad black streak across second suture connected to black distal portion of metepimeron, another black streak at anterior portion of metepimeron. Legs generally pale yellow except for blackish coxae, brownish spines and tarsi, and small black specks at knees. Wings hyaline with dark brown veins. One postcubital vein situated between base of wing and level of Ax 1. Ac nearer to Ax 2, Ab vein absent, Arculus at level of Ax 2, Px 11 and 10 in Fw and Hw, respectively; R 4 + 5 arising distal to subnodus, IR 3 a little distal to that. Pt brownish, rectangular. Abdomen: Abdominal segments generally pale except for brownish basal half of S 1, and S 2 with broad light brown tinge across middle and narrow blackish apical ring. S 3 – 6 with narrow apical and basal blackish rings, S 7 with distal half brownish, S 8 – 10 black with brownish tinge on ventral portion of S 10. Posterior abdominal segments grossly swollen; basal portion of S 7 somewhat more robust than S 6, then gradually broadening, achieving its broadest width at S 8, which is almost five times width of S 3 – 6, and slowly tapers to S 10, which is about three times width of S 3 – 6. Cerci (Figs. 4 – 5) pale yellow, longer than S 10. In lateral view, basal half of cerci sharply directed dorsad, distal portion slightly bent ventrad; small dorsal tooth situated at base of distal portion, inner angle of tip distinctly angulate and directed ventromedially. Viewed dorsally, basal half broad, sub-cylindrical; distal portion dorsoventrally flattened with ventromedial portion triangularly produced and slightly concave medially. Paraprocts similar to cerci in length, pale yellow except for dark brown tip; basal four-fifths robust, distally flattened and acutely curved anterodorsad, tip slightly serrate. Measurements of holotype: abdomen + cerci 26, Hw 16. Variation in males. Tip of paraproct smooth and triangularly blunt in some specimens. Metepisternal dark marking more extensive in some individuals, perhaps an age-related character. Measurements: abdomen + cerci 26 – 28, Hw 16 – 17. Female. Similar to male in coloration, venation and prothoracic structure, except for short, erect anterior lobe of prothorax. Abdomen starts to expand at apical four-fifths of S 6 and reaches maximum width on basal portion of S 7, about 3.5 times width of S 3 – 5. Basal third of S 8 slightly constricted, about three times width of S 3 – 5. S 10 twice width of S 3 – 5. Measurements: abdomen 25 – 26, Hw 16 – 17.	en	Villanueva, Reagan Joseph T., Schorr, Martin (2011): Two new damselfly species from Polillo Island, Philippines (Odonata: Platystictidae).
