Abbreviations: nl, nodal line. Scale bars: 1 mm. Male genitalia . Pygofer, in lateral view (Figs 4A , 4B ), with posterior margin slightly sinuate, more or less convex medially, anterior margin produced in a pair of broad and large sclerotised processes ventrolaterally; in ventral view (Fig. 4D ), far longer than in dorsal view (Fig. 4C ), with ratio of ventral to dorsal width about 4.5:1. Gonostyles (Fig. 4A, B, D ) elongate, in ventral view (Fig. 4D ), inner area along ventrolateral carina less sclerotised and filmy, dorso-basal process directed dorsolaterad; in lateral view (Fig. 4A, B ), ventrolateral carina strongly ridged from base to apex. Aedeagus (Fig. 4E-H ) large and elongate, as long as gonostyles; in right lateral view (Fig. 4F ), right apical process directed dorsad and curved laterocaudad; in left lateral view (Fig. 4G ), left process large and broad, base narrow and twisted, remaining cultrate, directed laterocaudad. Segment X (Fig. 4C ) slender and elongate, anal style relatively small, not reaching to apex. Figure 4.

Catullioides rubrolineata is newly recorded from Vietnam and Laos. Our specimens are distinctly larger than those recorded from Taiwan, China by Yang et al. (1989) . Their data showed the body length of C. rubrolineata from Nantou, Taiwan as 5.27 +/- 0.11 mm in males and 5.76 +/- 0.33 mm in females ( Yang et al. 1989 ). The type specimens of C. rubrolineata from Indonesia (6.5-8.0 mm) are also a little shorter than the specimens we examined ( Bierman 1910 ). Unfortunately, we did not examine the syntypes of Bierman (1910) and the specimens of Yang et al. (1989) , and identified this species based on our critical review of the literature.
