Type materials.

Holotype: China • 1♂; Hainan Province, Sanya City, Tianya district, Hongxin village, Hongxinxi River; 18°27.78'N, 109°27.88'E; alt. 150 m; 22-vii-2022; light trap; L. Peng & H. Zang leg.; NJAU Tricho-20220722-0001. Paratypes: China • 2♂; same data as holotype; NJAU Tricho-20220722-0002 to Tricho-20220722-0003 • 2♂; Hainan Province, Sanya City, Tianya district, Fuwan reservoir; 18°16.80'N, 109°28.94'E; alt. 60 m; 25-vii-2022; light trap; L. Peng & H. Zang leg.; NJAU Tricho-20220725-0001 to Tricho-20220725-0002.

Diagnosis.

This species is similar to Paduniella nama Johanson & Oláh, 2010 from Vietnam. However, P. sanyaensis sp. nov. can be easily distinguished by the following characteristics: (1) the tergum IX is similar in width to the sclerotized strips in lateral view, whereas in P. nama tergum IX significantly wider than sclerotized strips; (2) the superior appendages are elongate-triangular in lateral view, but subrectangular in P. nama ; and (3) the phallobase is enlarged, nearly triangular in lateral view, a feature missing in P. nama .

Description.

Male. Length of each forewing 2.1-2.3 mm (n = 5), holotype 2.3 mm. Specimens in alcohol uniformly pale yellow-brown, antennae annulate with brown. Genitalia. Sternum IX in lateral view with lower portion subrectangular and upper portion produced anterodorsad on each side into slender lobe (Fig. 6C View Figure 6 ); in ventral view transversely subrectangular (Fig. 6A View Figure 6 ). Sclerotized portion of tergum IX L-shaped, upturned distally, distal end membranous in lateral view (Fig. 6C View Figure 6 ); somewhat crescentic in dorsal view (Fig. 6B View Figure 6 ). Superior appendages elongate-triangular in lateral view (Fig. 6C View Figure 6 ); lightly twisted and triangular in dorsal view (Fig. 6B View Figure 6 ). Sclerotized strips slightly clavate in lateral view (Fig. 6C View Figure 6 ). Median process slender, tubular, arising from anterior bases of sclerotized strips above phallobase (Fig. 6B, C View Figure 6 ). Inferior appendages each with basal 1/4 broad, then narrower, with upper and lower margins parallel to each other and slightly sinuous, apex truncate in lateral view (Fig. 6C View Figure 6 ); curved mesad with apex slightly enlarged in ventral view (Fig. 6A View Figure 6 ); mesal branch of each inferior appendage arising from middle part of inner surface, elongate-triangular in ventral view (Fig. 6A View Figure 6 ). Phallobase well developed, subtriangular, about half as long as phallicata in lateral view (Fig. 6C View Figure 6 ); subcircular in ventral view (Fig. 6A View Figure 6 ); phallicata curved posteroventrad, compressed, with apex enlarged in lateral view (Fig. 6C View Figure 6 ); slender in ventral view (Fig. 6A View Figure 6 ); paramere slender, shorter than phallicata in lateral view (Fig. 6C View Figure 6 ).
