Sogana pseudohopponis View in CoL sp. nov.

( Figs. 5 View FIGURES 1 – 6 , 13–15 View FIGURES 7 – 15 , 21, 23 View FIGURES 16 – 23 , 26 View FIGURES 24 – 35 , 36–39 View FIGURES 36 – 47 , 48 View FIGURES 48 – 51 , 49)

Description. Length (from apex of vertex to tip of fore wings): ď 10.0 mm.

Similar to S. hopponis Matsumura , but color lighter, yellowish brown. Vertex ( Figs. 5 View FIGURES 1 – 6 , 13, 14 View FIGURES 7 – 15 ) with four black spots at apex (the basal one brownish); lateral carina ( Fig. 13 View FIGURES 7 – 15 ) blackish; central disc with a pair of fuscous patches on posterior margin. Ocelli ( Fig. 15 View FIGURES 7 – 15 ) without suffusion.

Vertex with anterior margin projected at an obtuse angle in dorsal view, lateral areas depressed; median carina diverging medially, protruding forward from base to anterior level of eyes. Fore wings with 16 apical cells and 7 subapical cells, the two middle anteapical cells not equally long. Spines of hind legs: hind tibia laterally 3, distally 7, basitarsus distally 7.

Proportions. Vertex with ratio of median length to the widest breadth 1.03:1, frons with ratio of median length to the widest breadth 1.54:1, pronotum with ratio of width to median length 4.35:1, pronotum and mesonotum together medially about 1.54 times as long as median length of vertex, fore wings with ratio of length to maximum breadth 3.54:1.

Male genitalia ( Figs. 26 View FIGURES 24 – 35 , 36–39 View FIGURES 36 – 47 , 48, 49 View FIGURES 48 – 51 ) with pygofer with dorsolateral angles produced, distinctly forming an obtuse angle in lateral view ( Fig. 26 View FIGURES 24 – 35 ). Anal tube ( Figs. 26 View FIGURES 24 – 35 , 36 View FIGURES 36 – 47 ) slightly bent ventrad, distinctly transverse-concave in distal fifth. Gonostylus (26, 38, 39) 3.8 times as long as broad in lateral view. Aedeagus ( Figs. 37 View FIGURES 36 – 47 , 48, 49 View FIGURES 48 – 51 ) with three processes: one anterodorsally directed process arising from the left side at apical fifth, reaching to middle of aedeagus, and having a distinct, sub-apical tooth directed dorsally and inwardly; one anterodorsally directed process arising from the right side at apical third, with a stout sub-apical tooth directed dorsally and inwardly; the third process relatively long and strong, apically lanceolate, arising below the right process from ventral side and directed posteriorly; endosoma more or less expanded, endosomal process sinuous, long and thin; phallotrema exposed apically ( Figs. 48, 49 View FIGURES 48 – 51 ); periandrium stout, with a tongueshaped process directed caudad on ventral side.

Material examined. Holotype ď, LAOS: Nam Kading (stream), 21.IV.1965 (J. L. Gressitt) ( BPBM).

Etymology. This new species is named for its general similar appearance with S. hopponis Matsumura, 1914 .

Distribution. Laos (Nam Kading).

Remarks. In external appearance, this species is very similar to hopponis Matsumura, 1914 from Taiwan, but differs from the latter in the vertex with median carina diverging medially, aedeagus with left process very short, just reaching to middle of aedeagus, with a distinct, sub-apical tooth directed dorsally and inwardly, the right process with a stout, sub-apical tooth directed dorsally and inwardly, and in having a long and thin endosomal process ( Figs. 48, 49 View FIGURES 48 – 51 ).
