Micromimetus sunweni   sp. nov.

( Figs 60–61 View Figs 54–65 , 112–116 View Figs 106–117 , 136–139 View Figs 136–146 )

Type material. HOLOTYPE: ♁, TAIWAN: TAITUNG: Lanyu Island , 22.05, 121.53, 7–10 Aug 2000, C. S. Lin & W.T.Wang ( AMNH _ PBI 00380619 View Materials ) ( NMNS, No. 3443-1009)   . PARATYPES: TAIWAN: same data as for holotype, 4 ♁♁ 1 ♀ ( NMNS).

Description. Male. Body ovoid, slightly elongate, medium-sized compared to congeners, 3.38–3.70 mm. COLOURATION: Body generally yellow brown, partly darkened (proportion of yellowish areas greater than dark areas). Head pale castaneous; clypeus fuscous. Antenna pale brown, segments I and II partly or narrowly infuscate; III and IV dark brown. Labium yellowish brown, partly tinged with red, apex of segment IV fuscous. Pronotum somber ochreous, with a distinct dark fascia posteriorly; scutellum yellow; pleura almost uniformly yellow brown. Hemelytron yellowish brown, slightly tinged with red; inner and posterior parts of corium, and posterior 0.50–0.66 of clavus darkened; cuneus entirely pale; membrane pale grayish brown, semitransparent, partly narrowly obscured along veins. Coxae and legs yellow brown; apical part of metafemur sometimes with obscure, irregular rings; tibia without spot at base of spine; tibial spines reddish brown. Abdomen ochreous. SURFACE AND VESTITURE: Dorsum with uniformly distributed, pale, reclining setae intermixed with silvery, recumbent setae. Pronotum weakly and shallowly rugose. Abdomen shiny. STRUCTURE: Vertex carinate basally. Antennal segments III and IV filiform. Labium slightly exceeding apex of metacoxa. Pronotal collar slightly narrower than basal carina of vertex; scutellum flat; ostiolar peritreme rather large ( Fig. 114 View Figs 106–117 ). Parempodia narrow, rhombic, with sharp apex. GENITALIA ( Figs 136–139 View Figs 136–146 ): Pygophore with a prominent PS ( Fig. 136 View Figs 136–146 ). Parameres small, slender; left paramere C-shaped, with sensory lobe not strongly inflated ( Fig. 138 View Figs 136–146 ); hypophysis with a single, elongate process; right paramere ovoid, with tiny hypophysis; endosoma with short primary lobal-sclerite from secondary gonopore aperture (PL) connecting to distal, bifurcate sclerite and with a thin, secondary lobal-sclerite (SL); seminal duct not expanded apically ( Fig. 139 View Figs 136–146 ).

Female. Larger than male, otherwise similar; length 3.99 mm. GENITALIA: Not examined.

Measurements (in mm). ♁/ ♀: Total length of body 3.38–3.70 / 3.99; head width including eyes 0.93–0.96 / 1.05; vertex width 0.28–0.29 / 0.36; lengths of antennal segments I–IV 0.60–0.62, 1.65–1.70, 1.14, 0.60 / 0.59, 1.50, 0.95, 0.60; labial length 1.51–1.62 / 1.59; mesal length of pronotum including collar 0.73–0.77 / 0.84; basal width of pronotum 1.21–1.31 / 1.53; maximum width across hemelytron 1.41–1.56 / 1.80; lengths of metafemur, tibia and tarsus 1.51–1.58, 2.32–2.55, 0.58–0.60 / 1.62, 2.40,? (missing).

Differential diagnosis. Recognized by its distinct yellow brown colouration; clear dark fascia on posterior pronotum ( Fig. 60 View Figs 54–65 ); yellow anterior clavus, lateral corium, entire scutellum and cuneus; almost wholly yellow brown ventral surface including legs; prominent pygophoral spine; generally slender parameres; shortened primary lobe on endosoma. A combination of these characters and isolated distribution on Lanyu Island enable this new species to be distinguished from other known Micromimetus   species (e.g., Figs 58–59 View Figs 54–65 ).

Etymology. Named in honor of Sun Wen (1866–1925) [often called Sun Yat-Sen], known as ‘the Father of Nation’ and ‘Forerunner of the Revolution.’

Biology. Unknown.

Distribution. Taiwan (Lanyu Island).
