Description of six new species of Oriental Paduniella (Insecta: Trichoptera: Psychomyiidae) Author Johanson, Kjell Arne Author Oláh, János text Zootaxa 2010 2548 43 56 journal article 10.5281/zenodo.196778 043d06b4-7867-49a4-8214-ca0b91e47b4a 1175-5326 196778 Paduniella sabarmata , new species Figs 19–21 Paduniella sabarmata , new species is unique in having the combination of a deeply bifurcating main branch of the inferior appendages; an anterad orienting, narrow dorsal part of sternite IX, being about 1.5 times longer than the ventral part of sternite IX; the presence of a large dorsal subapical process on the median process of the phallic apparatus; and a widely drop-shaped apex of phallicata. The species resembles P. f i s s a (from India ) from which it is separated by the inferior appendages being wider before the point of apical bifurcation, and the apical lobes of the main branch of the inferior appendages are parallel. The superior appendages of P. sabarmata are wider in lateral view than those of P. fissa . The species resembles P. s i v e c i Chantaramongkol & Malicky, P. methinee Chantaramongkol & Malicky , and P. thitima Chantaramongkol & Malicky , P. ceylanica Ulmer , P. pandya Schmid , P. mahindra Schmid and P. sangkamittra Schmid (all Sri Lanka ) in the bifurcating apex of the inferior appendages. Paduniella sabarmata sp. n. is separated from all these species in the shape of sternite IX and the phallic apparatus. Paduniella burmana , new species has also deeply bifurcating apex of inferior appendages, but in that species the sternite IX is ventrally narrower, the superior appendages are narrower, the inferior appendages are dorsally convex in lateral view, the median process of the phallic apparatus lacks the dorsal, sub-apical lobe, and the phallicata is asymmetrically dropshaped at the apex. FIGURES 19–21. Paduniella sabarmata , new species , male holotype. 19—genitalia, lateral; 20—genitalia, ventral; 21—phallic apparatus, lateral. Scale bar = 0.2 mm, refers to all figures. Male genitalia. Sternite IX narrowly club-shaped in lateral view ( Fig. 19 ); wide ventral part with straight anterior margin, posterior margin concave with small protuberance at dorsal and ventral corners; dorsal part of sternite IX equally wide along its length, slightly curving anterad, nearly 2 times longer than ventral part; joining tergites IX immediately above mid-height of genitalia. Narrow dorsal part of sternite IX in right angle with ventral part of sternite IX. Dorsal apex of sternite IX connecting to sternal strip near dorsal apex of strip ( Fig. 21 ). Sclerotized part of tergite IX short, straight, oriented posteroventrad, narrowly rectangular in lateral view ( Fig. 19 ); surrounded by membrane with microtrichia. Superior appendages long, dorsal and ventral margins weakly convex in lateral view; nearly straight, with central band of setae; apex rounded. Median branch of inferior appendages visible above main branch of inferior appendage in lateral view ( Fig. 19 ); in ventral view ( Fig. 20 ), forming laterad curving processes with rounded apices; originating from mid-length of main branch ( Fig. 19 ). Ventral lobe of inferior appendages reduced to short, weakly developed, longitudinal elevation along mesal margin as seen in lateral view ( Fig. 19 ); with ventral setae. Main branch of inferior appendages straight, orienting posteriorly along its lengths; narrowest shortly after mid-length, widening towards apex; ventral margin weakly undulating ( Fig. 19 ); apex widely incised; incision nearly as long as width of inferior appendages at point before incision; incision with nearly parallel sides; resulting in dorsal and ventral lobes equally long, oriented posteriorly ( Fig. 19 ). Phallic apparatus connecting to sternite IX and tergite IX by long, slender, nearly parallel-sided sternal strip ( Fig. 21 ). Phallobase spoon-shaped in lateral view; with strongly undulating dorsal margin; shorter than sternal strip; nearly straight; oriented anteroventrad. Median process about as long as phallicata; indistinctly separated from phallobase; curving posteriorly along basal 1/3rd; distal 2/3rds straight, parallel-sided along its length, except slightly wider at base; apex very slender, with minute spines; wide process present on dorsal margin before apex ( Fig. 21 ). Anterior 3/5ts of phallicata nearly equally wide, with slightly undulating dorsal and ventral margins; nearly straight; widening at distal 3/5ts into asymmetrical club-shaped apex with convex dorsal and ventral margins; apex truncate. Paramere absent. Male holotype : INDIA , Gujarat Ghandinagar Sabarmati R., 22.iv.1992 , leg. János Oláh (OPC, alcohol). Paratypes : same data as holotype— 2 males (OPC, alcohol); same data as holotype— 1 male (NRM, alcohol). Distribution: India . Etymology: Sabarmata , from the type locality, Gujarat Ghandinagar Sabarmati River.
