( Figs 25–27 , 52 , 116–118 , 174–176 ) Type material. HOLOTYPE : ♁, TAIWAN : PINGDONG (= PINGTUNG ): Sheding , 21°57′24.7″N , 120°49′40″E , UV lighting, 22 Sep 2012 , J.F. Tsai & Y.C. Lan ( NMNS ) ( AMNH _ PBI 00380632 ). Differential diagnosis. Recognized by its tiny size; relatively ovoid body; yellowish brown antenna with reddish extreme base of segment I; narrowly distributed MFP ( Fig. 52 ); triangular pygophore ( Fig. 174 ); roundly inflated sensory lobe of left paramere ( Fig. 175 ); and C-shaped endosoma, with an apically bulbous process near apex ( Fig. 176 ). Combination of these characters enables this new species to be distinguished from other Asian congeners. Description. Male ( holotype ). Body generally coffee brown, small, rather ovoid ( Figs 25–26 ); dorsal surface weakly shining, with sparsely distributed, pale, simple, semierect setae. Head short, with reddish basal margin; eyes small, less than half as wide as vertex in dorsal view. Antenna almost uniformly yellowish brown; extreme base of segment I reddish brown; segment II slightly longer than III. Labium reddish brown, exceeding apex of metacoxa, reaching abdominal sternum VIII. Pronotum weakly shining, trapezoidal, not strongly constricted anteriorly; pleura shiny dark brown; scent efferent system somber pale brown, small. Hemelytron with two pairs of white maculae as in Fig. 25 (anterior macula across clavus, corium and embolium rectangular and posterior macula across apices of corium and embolium triangular); FWS roundly notched ( Figs 27 , 117 ); cuneus brown, narrowed; membrane pale smoky brown. Coxae and legs pale brown; apical half of metafemur and basal 1/3 of each tibia obscure; MFP distributed narrowly on median part of metafemur, with each plectrum tiny, circular ( Figs 52 , 118 ). Abdomen wholly fuscous, short. Male genitalia ( Figs 174–176 ): Pygophore triangular ( Fig. 174 ); left paramere with roundly expanded sensory lobe ( Fig. 175 ); endosoma C-shaped, with an apically bulbous process near apex ( Fig. 176 ).
