Lis, Barbara, Dang, Kai & Bu, Wenjun, 2015, New records of Pseudophatnoma laosana B. Lis, 1999 (Hemiptera: Tingoidea: Cantacaderidae) from China and Thailand, with illustration of its male genitalia, Zootaxa 3946 (4), pp. 595-598 : 595-597

Genus Pseudophatnoma Blöte, 1945

Pseudophatnoma Blöte, 1945: 78 ; Drake and Ruhoff, 1965: 40; Péricart, 1991: 49; Froeschner, 1996: 15; Lis, 1999a: 28. Type-species by original designation: Pseudophatnoma corniculata Blöte, 1945 .

Froeschnerocader Péricart, 1986: 245; synonymized by Péricart, 1991: 49. Type-species by original designation: Froeschnerocader denticollis Péricart, 1986 .

Diagnostic characters for the genus. Head apex not reaching the distal ends of the first antennal segment; head dorsal surface with two pairs of thin long spines, i.e., the jugo-frontal spines (located on the level of the base of the clypeus), and the preocular spines (located between the eyes); bucculae very low ( Fig. 1 ). Rostrum long, reaching at least the third abdominal segment ( Fig. 1 C). Pronotal disc convex with five longitudinal carinae ( Fig. 1 B); paranota wide, bilobed, bearing the forward-directed spine-like projection in its triangular anterior lobe ( Figs. 1 A and B). Scutellum entirely or partially covered by the posterior margin of pronotum. Hemelytra wide, broadly expanded at their bases, tiny areolated; its costal area wide, bearing 9–11 rows of areolae at mid-length; subcostal area with several indistinct transverse veins; discoidal area with one or two transverse veins.

Diagnostic characters for P. laosana . It differs from other species of the genus in having the scutellum not entirely covered by the posterior margin of pronotum and therefore partially visible in dorsal view – Fig. 1 B (in the two other species it is invisible, being entirely covered by the posterior margin of pronotum). Moreover, the costal area is widest at its posterior part ( Fig. 1 ), whereas in P. denticollis and P. corniculata it is widest at its mid-length. The male genitalia are illustrated in Fig. 2 .

Material examined. CHINA: 1♂, Yunnan Province, Xishuangbanna Dai Autonomous Prefecture, Mengla County, Menglun Township, Xishuangbanna Tropical Botanical Garden (21.93°N, 101.25°E), 531 m, 15.VIII.2010, light trapped, K. Dang leg. THAILAND: 1♂, Nakhon Ratchasima Province, Sakaerat Silvicultural Research Station, 25.IX.2013, A. Wolski leg.

Distribution. China (new record), Laos, Thailand (new record).

Remarks. Sizes of both newly collected specimens differ from those of the type specimen from Laos; therefore, updated measurements (in mm) for P. laosana are provided as follows: total body length: 7.41–7.70; body width: 3.57– 3.70; length of pronotum: 1.45–1.90; width of pronotum: 1.85–2.00; length of hemelytra: 5.18–5.45; length of discoidal area: 3.40–3.60; length of antennal segments: I 0.25–0.26, II 0.22–0.23, III 2.96–3.28, IV 0.57–0.64.
