Diagnosis. Colouration. Body completely pale brown except for dark apices of mandibles and black antennae and legs.

Body length. JJ: 8.0–10.0 mm, ♀♀: 10.3–12.5 mm.

Male ( Figs 175–176 ). Antennae 0.79 times as long as body. Pronotum convex, 1.76 times as wide as long, covered with very fine punctures, anterior margin slightly concave, unbordered, lateral margins rounded, convergent anteriorly, posterior margin widely rounded, slightly sinuate, lateral and posterior margins thinly bordered. Posterior margin of abdominal ventrite IV narrowly vertically impressed, with wide shallow emargination in middle. Longitudinal impression on last abdominal ventrite wide and deep in posterior two thirds, narrowed in basal third. Protarsomere I elongate triangular. Metatibial spur short, narrow.

Aedeagus ( Fig. 187 ). Median lobe of aedeagus 3.02 times as long as wide; widest in basal quarter, moderately narrowed anteriorly, apical seventh narrow, slightly divergent anteriorly. Lateral view: median lobe almost straight in middle part, apical part bent; lateral elevation triangular, placed in anterior fifth of aedeagus length. Dorsal process lanceolate, widest in middle, 3.73 times as long as wide, 0.78 times as long as median lobe, apex sharp. Lateral view: dorsal process rounded in basal half, apical half wide, basal half narrow, surface of apical quarter covered with several oblique furrows.

Female. Antennae 0.70 times as long as body. Metatibial spur absent. Last abdominal ventrite with posterior margin entire. Sternite VIII subtriangular, posterior margin nearly straight with middle part convex and small incision in middle, lateral margins slightly rounded, middle part of posterior half impressed, lateral parts separated from middle part by distinct keel, lateral parts of posterior margin and margins of median impressions covered with long setae; tignum short, 0.20 times as long as sternite VIII ( Fig. 210 ). Spermatheca with poorly developed nodulus, cornu large, C-shaped ( Fig. 199 ).

Differential diagnosis. Liroetis fulvipennis is similar to L. jeanvoinei and L. nigriceps . Both, L. fulvipennis and L. nigriceps have brown dorsum but the head is black (or darkened) in L. nigriceps and brown in L. fulvipennis . In L. fulvipennis metatibial spur is present in males but absent in females, while metatibial spur is present in both sexes in L. nigriceps . Dorsal process of aedeagus is lanceolate and widest in middle in L. fulvipennis but wider and subparallel in anterior two thirds in L. nigriceps ( Figs 187 , 193 ). Dorsum of L. jeanvoinei is reddish brown and median lobe of aedeagus is almost parallel, with dorsal process very narrow and parallel ( Fig. 188 ). Another similar species is L. modestus which differs in bicolour legs and dorsal process of aedeagus ( Fig. 192 ) widest in anterior third (legs black and dorsal process of aedeagus widest in middle in L. fulvipennis ).

Diagnosis. Colouration. Body completely reddish brown, except for mandibles, maxillary palpi, antennae and legs black.

Body length. JJ: 10.5–12.5 mm, ♀♀: 12.0– 13.5 mm (J ♀: 11.0–14.0 mm based on the original description).

Male ( Figs 182–183 ). Antennae 0.76 times as long as body. Pronotum 1.73 times as wide as long, covered with fine punctures, anterior margin slightly concave, unbordered, lateral margins rounded, convergent anteriorly, pronotum widest in posterior quarter. Posterior margin of abdominal ventrite IV with two small transverse triangular processes separated by small U-shaped incision. Longitudinal impression on last abdominal ventrite wide and deep in posterior half, narrower in basal half. Pygidium with triangular apex. Metatibial spur short, wide and flat.

Aedeagus ( Fig. 188 ). Median lobe of aedeagus 3.46 times as long as wide; wide and parallel, apical part transversely cut, with short apical process, with distinct very narrow median furrow. Lateral view: median lobe bisinuate, moderately rounded in basal two thirds; lateral elevation triangular, placed in anterior fifth of aedeagus length. Dorsal process narrow, 7.50 times as long as wide, 0.80 times as long as median lobe, subparallel, apex sharp. Lateral view: dorsal process regularly rounded, very wide, constricted in basal third, apex sharp, surface of apical two thirds covered with several oblique deep furrows.

Female ( Fig. 184 ). Metatibial spur absent. Last abdominal ventrite with posterior margin entire. Sternite VIII subrhomboidal, posterior margin with small triangular incision followed by long keel, surface with two elevated triangular plates, long setae accumulated along posterior and partly inner margins of those plates; tignum 0.40 times as long as sternite VIII ( Fig. 211 ). Spermatheca without visible nodulus, cornu C-shaped, gradually narrowed towards apex, spermathecal duct distinctly bent ( Fig. 200 ). Differential diagnosis. Due to similar colouration and robust body, Liroetis jeanvoinei is similar to L. fulvipennis and L. nigriceps . While dorsum of L. fulvipennis and L. nigriceps is brown (in L. nigriceps moreover with black or darkened head), L. jeanvoinei is reddish brown dorsally. While in L. jeanvoinei and L. fulvipennis metatibial spur is present in males but absent in females, in L. nigriceps metatibial spur is present in both sexes. Median lobe of aedeagus of L. jeanvoinei is almost parallel, with dorsal process very narrow and parallel ( Fig. 188 ), contrary to moderately convergent median lobe of aedeagus and dorsal process lanceolate in L. fulvipennis , and aedeagus with dorsal process wider and subparallel in anterior two thirds in L. nigriceps ( Figs 187 , 193 ).

Distribution. Vietnam (Lൺൻඈංඌඌංජඋൾ 1929, present paper), Laos (present paper).

Comments. Pseudoliroetis jeanvoinei was synonymized with Siemssenius fulvipennis by Kංආඈඍඈ (1989a). I examined the primary type material of both taxa and undoubtedly, they are not conspecific (see Differential diagnosis). Pseudoliroetis jeanvoinei is resurrected from synonymy with Siemssenius fulvipennis and transferred to the genus Liroetis .
