Figs 16 Holotype. ♂, "VIETNAM: Ha Tinh, Huong/ Son, 18°22'N , 106°13'E / 900m, April 20-28, 1998/ Malaise, AMNH, Carpenter/ Grimaldi, Herman, Silva, Long". Deposited in the Division of Invertebrate Zoology (Entomology), American Museum of Natural History, NY, with eventual deposition in the Institute of Ecology and Biological Resources Collection (IEBR), Hanoi, Vietnam. Paratypes. 4 ♂♂, with identical data as holotype; 1 ♂, with identical data except collected on 18 May 1998; 1 ♂, with identical data as holotype except collected at 600m above sea level on 7-14 April 1998 by K. Long; 1 ♂, with identical data as holotype except collected on 5 May 1998 by K. Long. All deposited in the AMNH. Type-locality. Vietnam, Ha Tinh Province, Huong Son, 18°22'N , 106°13'E . Diagnosis. The species has several diagnosable characters separating it from the type species: 1) body size slightly larger (6.2-8.2 vs. 6.0 mm); 2) more vivid light brown-tan bicoloration (Fig. 1); 3) slightly broader elytral epipleura (Fig. 2); 4) bifurcate MP3+4 in the hind wing (Fig. 3); 5) more slender metatibia (Fig. 4); and, 6) more elongate parameres in the male genitalia (Fig. 6).

BL: 6.2-8.2 mm; BW: 2.7-3.4 mm; PW/PL = 1.5-1.6; EL/ EW = 3.6-3.8; EL/PL = 3.8-4.4; BW/PW = 1.4-1.5. The species is very similar to the type species in general morphology except the aforementioned differences, and need not be repeated here. As described for Oculogryphus fulvus except: aedeagal sheath has length of 0.9 mm and width of 0.6 mm; abdominal tergites IX and X clearly recognizable individually (Fig. 5); aedeagus about 0.75 mm in length and 0.4 mm broad; parameres comparatively elongate, about as long as basal piece laterally (Fig. 6). Etymology. The specific epithet refers to the two-toned coloration which is more vivid in the new species than in Oculogryphus fulvus . Phenology. According to the available collection data, males appear at least from April to May.
