(Figs. 192, 201, 223–225, 234)

Polymorphanisus unipunctus Banks, 1939: 53 [Holotype female; China; USNM]; Banks, 1940: 206 (redescription of holotype female); Fischer, 1963: 209 (catalogue); Barnard, 1980 (redescription of holotype female); Malicky, 1998a: 402 (description of male).

Diagnosis. Male. Antennae 60 mm in length. Antennal flagellum brown with darker striations. Forewing 22 mm and hind wing 15 mm in length. Mesoscutum without evident markings. Mesoscutellum with two dark brown spots smaller than found in other species (Fig. 192). Tibial spurs 1.3.2.

Male genitalia. Inferior appendages two-segmented. In lateral view, phallus with squarish apex (Fig. 225). In dorsal view, segment IX with curved apex (Fig. 234). Segment X divided medially (Fig. 234).

Female. Antennae 40 mm in length. Antennal flagellum same colouration as male. Forewing and hind wing length same as male. Mesoscutum and mesoscutellum same as male (Fig. 192). Tibial spurs 1.3.2.

Material examined. Vietnam: 1 male, Nam Cat Tien, coll. H. Malicky, 17–25 June 1995 (HMPC); Thailand: 1 female, Umgebung Pai Huai Mae Ya, coll. H. Malicky, 20 April 2000 (HMPC); 1 female, Mae Hong Son, Muang Pai Resort, coll. H. Malicky, 3–16 May 2005 (HMPC).

Distribution. China, Laos, Thailand, Vietnam.

Remarks. Banks (1939) briefly described this species for the first time using a female specimen from China, which was designated as holotype. A redescription was made by Banks (1940) with a remark “new species” using the designated holotype and additional one female which was designated as paratype (in MCZ). Fischer (1963) regarded the first description of this species (Banks, 1939) as “nomenclaturially invalid” and the authorship of this species to be Banks (1940) probably because of the remark “new species” in the second paper. Barnard (1980), with his redescription of holotype of this species, disagreed on Fischer’s (1963) opinion and corrected the authorship of this species to be Banks (1939). Malicky (1998a) provided a male description of this species. We follow Barnard (1980) that Banks (1939) officially described this species for the first time with valid holotype designation and description.
