Vertomannus (Vertomannus) borneensis sp. n.

Type material.

Holotype: female, pinned. Original label: "C. Borneo, Long Nawang, leg. Mjöberg 1925" [printed] (ZMAN).

Measurements (in mm). Body length: 5.85; head length with neck: 1.63, width: 0.95, interocular space: 0.6; anteocular length: 0.3, postocular length: 0.5, neck length 0.53; pronotum: length: 0.95, width: 1.55; scutellum: length: 0.95, width: 0.6; length of claval commissure: 1.4; Length of antennal segments: I 0.75, II 1.8, III 1.5, IV missing; lengths of labial segments: 1.65 = I 0.5, II 0.35, III 0.5, IV 0.3

Description.

Head globose, shiny, frons smooth, not wrinkled, not punctured (Fig. 3). Anteocular part shorter than postocular part without neck. Long hairs present on head and neck. Labium surpassing anterior margin of prosternum but ending before fore coxae, segment I reaching hind margin of eyes (Fig. 4).

Thorax: Pronotum trapezoidal, with long hairs, lateral margin concave, anterior lobe impunctate, narrower than posterior lobe which is punctured, posterior lobe a little more declivous than anterior lobe in lateral view. Scutellum longer than wide, sparsely punctured, with some long hairs.

Legs slender and long, fore femur with a single spine, provided with hairs which are longer than diameter of femur. Corium with two rows of punctures along claval suture and with irregular punctures on apical half of mesocorium, not pubescent. Membrane with four distinct veins, not forming cells.

Abdomen: densely pubescent with decumbent silvery hairs.

Colouration. Body fuscous. Posterior lobe of pronotum pale- brown except middle part, antenna pale. Bases of femora pale stramineous, apical halves brown, tibiae basally pale yellowish brown, gradually lightening towards apex, tarsi faint light brown. Scutel lum with tiny stramineous spot at apex. Corium with extensive pale colouration, basal half pale except punctures, behind this area a wide stripe mostly ochraceous with brown spots and a tiny rounded white spot at apex of claval commissure; apex of corium brown with extensive white subapical spot. Membrane pale brownish, with some white spots.

Discussion.

Vertomannus borneensis sp. n. is smaller than the other described species of the genus. The rounded, shining anteocular part of head (without wrinkles) is diagnostic value. The long pilosity on head is more sparse than for other species. Vertomannus crassus Zheng, 1981 and Vertomannus validus Zheng, 1981 are clearly different in multispinose and thick fore femora and large globose anterior pronotal lobe. Vertomannus brevicollum Zheng, 1981 has a very short neck, shorter than postocular part, and the apical part of abdomen is yellowish brown. Vertomannus capitatus , Vertomannus emeia Zheng, 1981 and Vertomannus ophiocephalus Zheng, 1981 have a longer labium reaching the fore coxae and have at least two spines on fore femora. Additionally, Vertomannus ophiocephalus has a longer neck than the postocular part of head; and moderately shortened hemelytra, not reaching the end of the abdomen. The pale subapical spot of corium has concave fore margin at Vertomannus capitatus , however, Vertomannus borneensis has this spot with straight fore margin.

Etymology.

The name of the species refers on the type locality, “borneensis” is a Latin adjective in nominative case with meaning "origin from island Borneo" (now Kalimantan).
