Figures 20, 85-93 Diagnosis. This species is similar to Microserangium bacthaiensis Hoang , 1978 in morphological characters and male genitalia, but it can be distinguished by the different shape of the penis guide. Description. TL: 1.25-1.38mm, TW: 1.12-1.22mm, TH: 0.76-0.82mm, TL/TW: 1.12-1.14; PL/PW: 0.42-0.44; EL/EW: 0.94-0.95; HW/TW: 0.43; PW/TW: 0.76. Body shiny and glabrous (Fig. 20). Dorsum uniformly black.
