description: Diognetus dhampus sp. nov.   
(Figs 2D, 7E–F, 8H–J, 27A–E)  
 Type material. HOLOTYPE: J, NEPAL: Kasuki District, Dampas Dara [= Dhampus], 28.306, 83.843, 23–24 Oct 1981, M. Sakai (AMNH _ PBI 00380746) (NMTU). PARATYPE: NEPAL: same data as for holotype, 1 J (NSMT).   
 Additional material examined: NEPAL: Rasuwa District, Dhunche, 28.1120, 85.2973, 1,950 m alt., at FL light of lodge balcony, 8–9 Jun 2006, T. Yasunaga, 1 ♀ (TYCN).   
 Description. Body elongate ovoid, moderate in size, 5.4–5.8 mm. COLORATION: Dorsum dark reddish-brown, partly speckled with dark brown (Figs 2D, 7E). Antennae pale brown; apex of segment II, apical 1/3 of segment III and entire segment IV dark brown. Labium pale brown, partly tinged with red; apical half of segment IV darkened. Pronotum relatively shining, widely fuscous except for brown anterior 1/3 and yellowish posterior margin; calli area with a pair of dark, ovoid spots; scutellum brown, with yellowish apex; pleura broadly fuscous; scent efferent system creamy yellow. Hemelytron reddish-brown; corium and clavus speckled with dark maculae; membrane smoky brown, with apically yellowish veins. Coxae and legs yellowish brown; metafemur with two dark rings subapically (basal one wider as in Fig. 7F); apical 1/3–1/2 of tarsomeres III darkened. Ventral surface of abdomen pale brown, with darkened lateral margins. SURFACE AND VESTITURE: As in generic diagnosis; scutellum rather matte. STRUCTURE: Eye large; vertex narrow. Antennal segment I slightly shorter than segment IV. Labium reaching metacoxa but not exceeding its apex. Scutellum somewhat swollen. Metathoracic scent efferent system as in Fig. 27C. Metatarsomere I slightly shorter than III; parempodia shorter than claw (Fig. 27D). MALE GENITALIA (Figs 8H–J, 27E): Left paramere with rounded, developed sensory lobe and rather narrow hypophysis (Figs 8I, 27E). Vesica with long RS, apically rounded MS and noticeable TP (Figs 8J). FEMALE GENITALIA: Not examined.   
 Measurements. See Table 1.   
 Differential diagnosis. Externally very similar to D. bagmaticus sp. nov., from which it can be distinguished by the antennal segment IV longer than segment I and lateral edge of the mesepimeron with the clustered, upright, rather long setae, in addition to the identical male genitalia.   
 Etymology. Named for the type locality, Dhampus (Kasuki District, central Nepal). Noun in apposition.   
 Biology. Unknown; available specimens were collected in deciduous broadleaf forest zone (1,500 –2,000 m alt.).   
 Distribution. Nepal (Kasuki and Rasuwa Districts).
