Two new Vertomannus species, Vertomannus flavus sp. n. (south Vietnam) and Vertomannus borneensis sp. n. (Borneo) are described. Vertomannus (Elongatomannus), subgen. n. (type species: Vertomannus flavus) is proposed.


Heteroptera, Rhyparochromidae, Ozophorini, Vertomannus, new species, distribution, Oriental Region


Rhyparochromidae is the largest family of Lygaeoidea containing more than half of the described species of the superfamily. Species of the rhyparochromid tribe Ozophorini are distributed all over the world (Slater 1964; Slater and O’Donnell 1995). The diversity of Ozophorini is highest in tropical America and southeast Asia, however, the Oriental Region is the least investigated area.

The ozophorine genus Vertomannus Distant, 1903 was described as monotypic, containing Vertomannus capitatus Distant, 1903 from Assam and Burma (Distant 1903). Breddin (1905) described Vertomannus tener Breddin, 1905 from Java, but Bergroth (1916) subsequently transferred it to Omacrus Bergroth, 1916. Later Zheng (in Zheng and Zou 1981) described five new species from China and provided a key for the Chinese species. Thus, there are six described species of Vertomannus at present.

This paper contains descriptions of two new species of Vertomannus from Vietnam and Borneo. One of the new species is morphologically strikingly different from all other species of the genus: therefore, a new subgenus is proposed for its accommodation.

Examination of the specimens was carried out using an ALPHA STO-4-65 Zoom and a Zeiss Disovery V8 stereomicroscopes. Measurements were taken using a micrometer eyepiece. Pictures were made using a Panasonic DMC G2 digital camera (12 Mpixel).

Genus Vertomannus Distant, 1903



Body elongate. Head not punctured behind ocelli, posterior part slender, forming a long neck. Postocular part of head with neck longer than anteocular part. Eyes prominent. Ocelli situated close to eyes. Neck exserted. Antenna and legs slender, long. Antennal segment I and femora thickened apically. Fore femur often thick, always with spines. Pronotum with transversal furrow usually well developed, anterior and posterior lobes well separated. Anterior lobe of pronotum narrower than posterior one. Lateral margins of pronotum not flattened, humeri without spines. Middle of scutellum slightly elevated. Clavus with three or four rows of punctures. Scent gland ostiole with prominent and short peritreme curving posteriorly. Evaporatorium indistinct. Basal part of abdomen dorsoventrally constricted, not or weakly punctured. Intersegmental sutures between abdominal sterna 4 and 5 usually not curving cephalad, reaching lateral margin of abdomen.

Discussion. The genus Vertomannus is similar to Cervicoris Slater, 1982, but the latter genus is different in having the anterior lobe of the pronotum globose, and the presence of a pair of long humeral spines. Additionally, Cervicoris has the intersegmental sutures between abdominal sterna 4 and 5 curving cephalad, not reaching the lateral margin of abdomen, which is a typical rhyparochromid character.

Descriptions of new taxa

Head elongate, anteocular part distinctly longer than postocular part without neck, nearly horizontal, weakly declivous, antennifers not closer to eyes than longitudinal diameter of eye. Head, especially neck, with sparse long and dense short pilosity, neck transversely wrinkled. Humeral angles of pronotum prominent, posterior lobe medially elevated. Apex of labium surpassing mid coxa. Scutellum triangular, with faint Y-shaped elevation. Clavus with four full rows of punctures.


The new subgenus can readily be separated from the nominotypical subgenus based on the above mentioned characters: all known members of Vertomannus (Vertomannus) have a globose head with only sparse long pilosity (without short hairs) and with a relatively short anteocular part, a smooth neck; humeral angles of pronotum not prominent, labium not surpassing fore coxa, scutellum without a distinct elevation and clavus with only three rows of punctures.

Type species (by present designation): Vertomannus (Elongatomannus) flavus sp. n.


Formed by the combination of the Latin prefix elongato- ‘elongate’ and –mannus, the former referring to the strikingly elongate head and neck characteristic for the subgenus, the latter referring to the genus Vertomannus. Gender masculine.

Body length: 9.75; head length with neck: 2.75, width: 1.0, interocular space: 0.55, anteocular length: 0.7, postocular length: 0.55, neck length 1.15; pronotum: length: 1.5, humeral width: 1.55; scutellum: length: 1.0, width: 0.9; length of claval commissure: 2.0; lengths of antennal segments: I 0.95, II 2.9, III 2.35, IV 2.45; lengths of labial segments: 5.05 = I 1.5, II 1.6, III 1.4, IV 0.55.


Body elongate, dorsum moderately shiny, thoracic sternum dull (Fig. 1). Head, neck and ventral side of body with short semidecumbent hairs, long erect hairs present only on head (Fig. 2).

Head: head-neck transition very gradual. Antennal segment I thickened apically, remaining segments long and filiform.

Thorax: pronotum trapeziform, lateral margin concave, anterior lobe narrower than posterior, anterior lobe without punctures except at margins, posterior lobe distinctly punctured, punctures with very short inconspicuous setae, posterior lobe a little more declivous than anterior lobe in lateral view. Scutellum triangular, width and length subequal, with dense punctures except faint Y-shaped elevation, with very fine, hardly visible hairs.

Legs slender and long, fore femur distally with two large spines and one small spine, with hairs as long as diameter of femur. Corium less punctured, not pubescent. Abdomen: densely pubescent with silvery hairs.

Colouration. Body stramineous, punctures brown. Head and antennal segment I reddish brown, antennal segments II-III stramineous with reddish apex, segment IV brown with basal third reddish. Lateral margin of anterior lobe of pronotum darker than disk, punctures on posterior part brown. Scutellum slightly darker than ground colour of body. Membrane honey-coloured, apical part translucent, subapically with a transverse stripe connected with a longitudinal stripe.

The long and stramineous body and the features in the diagnosis of the subgenus easily separate this species from all known Vertomannus species.


The species is named after the unique colouration. The epithet “flavus” is a Latin adjective in nominative case, meaning “yellow”.

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.


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).
