Type materials.

Holotype: China • 1♂; Hainan Province, Sanya City, Tianya district, Tangta reservoir; 18°24.55'N, 109°23.27'E; alt. 240 m; 24-vii-2022; light trap; L. Peng & H. Zang leg.; NJAU Tricho-20220724-0001. Paratypes: 25♂, 16♀; same data as holotype; NJAU Tricho-20220724-0002 to Tricho-20220724-0042.

Diagnosis.

This species is similar to Paduniella sampati Malicky & Chantaramongkol, 1993 from Thailand in having the superior appendages furcated at their bases in dorsal view and in the shape of the phallic apparatus in the lateral view. However, P. fasciaria sp. nov. can be easily distinguished by the possession of a slender median process.

Description.

Male. Length of each forewing 2.6-3.0 mm (n = 10), holotype 2.9 mm. Specimens with compound eyes black, antennae approximately of same length as forewings; body brown; head, bases of antennae, thorax covered with brown, short hair; wings mostly covered with brown, short hair; each forewing with transversal white band at middle (Fig. 5D, E View Figure 5 ). Genitalia. Sternum IX subrectangular with anterodorsal angle produced into subrectangular process in lateral view (Fig. 5C View Figure 5 ); and transversely elongate-rectangular with anterior margin having deep U-shaped incision in ventral view (Fig. 5A View Figure 5 ). Tergum IX membranous, with base fused with superior appendages, somewhat clavate in lateral view (Fig. 5C View Figure 5 ), directed posterodorsad; transversely subrectangular in dorsal view, with anterior margin slightly convex and posterior margin undulated (Fig. 5B View Figure 5 ). Superior appendages large, forming a parallelogram shape in lateral view (Fig. 5C View Figure 5 ); in dorsal view (Fig. 5B View Figure 5 ) each with basal portion furcate, basolateral lobe slightly longer than inner one, tapering distally with apex curved mesad and crossing apex of opposing superior appendage, setose subapically. Sclerotized strips slightly clavate in lateral view (Fig. 5C View Figure 5 ) and somewhat V-shaped in dorsal view (Fig. 5B View Figure 5 ). Median process mostly slender with sharp apex, insertion between sclerotized strips broad in dorsal view (Fig. 5B View Figure 5 ). Inferior appendages each with basal half broad, then abruptly narrowed at mid length and tapered towards apex in lateral view (Fig. 5C View Figure 5 ); basal half broad, then abruptly narrowed, with apex slightly enlarged and curved mesad in ventral view (Fig. 5A View Figure 5 ), mesal branch lamellar, setose, arising from middle part of inner surface (Fig. 5B, C View Figure 5 ). Phallobase well developed, basally clavate in lateral view (Fig. 5C View Figure 5 ); with upper margin having deep incision in ventral and lateral views (Fig. 5A, C View Figure 5 ), tapering from base to apex, phallicata tubular, curved slightly upwards in lateral view (Fig. 5C View Figure 5 ); about same length as phallobase (Fig. 5A, C View Figure 5 ).
