Paramblynotus chrysochaites , new species

FEMALE: Length 4.5–5.0 mm. Body entirely black. Antenna red brown. Legs red brown except coxae and metatarsus black. Wings transparent and slightly tinted. Body pubescence conspicuous and golden-tinted.

Antenna 13-segmented; flagellum filiform, not widened apically. Vertex foveate-reticulate with dense golden pubescence. Eye prominent and distinctly extended laterally beyond outer margin of gena. Ocellar plate raised, foveate-reticulate and finely carinate laterally, and defined laterally by distinct carina lined by a row of large foveae along interior side; a small triangular area present beneath anterior ocellus glabrous. Median frontal carina present only as a raised lamilate process above antennal sockets, semicirclar in lateral view. Upper face conspicuously pubescent entirely and foveate laterally; antennal scrobe distinctly depressed, glabrous, densely punctate anteriorly, and defined by carina laterally. Gena densely punctate and sparsely foveate, and densely pubescent. Lower face and clypeus densely punctate and foveate with conspicuous pubescence; anterior tentorial pits small; clypeopleurostomal sulcus and epistomal sulcus form a smoothly curved arch. Lateral occipital carina not reaching vertex. Occiput glabrous.

Anterior flange of pronotum finely longitudinally striate, submedian pronotal depressions separated far from each other medially. Anterior plate of pronotum densely finely punctate and pubescent. Pronotum dorsome- dially raised, slightly higher than mesoscutum; pronotal crest gradually raised medially into a small peak. Lateral pronotal carina distinct, reaching pronotal crest dorsomedially. Lateral surface of pronotum foveatereticulate with fine oblique striate component and conspicuously pubescent. Dorsal pronotal area superficially transversely striate, present only along anterior third of posterior margin of pronotum. Mesoscutum flat dorsally and transversely costate with superficial foveae set in rows. Scutellar sulcus divided by a median longitudinal carina and four submedian longitudinal carinae. Axillar area with conspicuous pubescence extended to cover lateral part of scutellar sulcus. Mesoscutellum foveate-reticulate; posterior margin raised and projected posteriorly into two apically rounded processes. Mesopleural triangle conspicuously pubescent and well defined ventrally by a smoothly curved carina. Median mesopleural impression percurrent and glabrate; upper mesopleuron glabrous; speculum sparsely punctate; and lower mesopleuron glabrous and pubescent. Metepisternum longitudinally carinate-rugose in upper part, conspicuously pubescent ventrally. Lateral propodeal carina percurrent, strongly raised dorsolaterally into a large, laterally inclined lobular process with very dense pubescence; median propodeal area finely pubescent with a complete median longitudinal carina crossed by submedian transverse carina. Rs+M of forewing arising from anterior third of basal vein. Marginal cell 4.0 times as long as wide and 1.8 as long as submarginal cell. Bulla on Sc+R 1 absent.

Petiole 0.56 times as long as wide in lateral view. Tergum 8 distinctly exposed; relative length of T3–8: 1.5:1.0:1.1:1.9:1.0:1.1; T3–4 glabrous with a few setigerous punctures; T5 punctate dorsolaterally, punctures coarse and sparse anteriorly; T6 with a large patch of conspicuous pubescence and finely punctate lateroventrally; T7 with a band of conspicuous pubescence dorsolaterally and finely punctate lateroventrally; and T8 pubescent. Apical teeth of metatibia short and blunt apically. 1mt/2–5mt 5 1.2.

MALE: Unknown.

Paramblynotus chrysochaites and P. rufipes are unique in the punctulatus group in (1) scutellar sulcus divided by several more or less equal longitudinal carinae into several foveae, (2) T8 of female metasoma distinctly exposed, (3) axillar area with conspicuous hair tuft, (4) T6–8 with conspicuous patch of long, golden hairs, and (5) apical teeth of metatibia short and blunt apically. In fact, they are more like the species of the ruficollis group in terms of these characters. However, they differ from the ruficollis group by the following characters: pronotal crest raised into a conspicuous peak anteromedially and mesoscutum flat dorsally. The species is further distinguished from P. rufipes in having pubescence of axillar area extended to cover lateral part of scutellar sulcus; mesoscutellum with a distinct emargination posteriorly and that posterior projection separated into two lobular processes; pubescence on pronotum and T6–8 very dense and long so that sculpture of the body parts is barely visible; the patch of pubescence on T6–8 covers posterior third of postpetiolar metasoma; and T6 distinctly longer than T3.

TYPE MATERIAL: HOLOTYPE: ♀, Malaysia: Negri S., Pasoh Forest Reserve (Forest gap), 1978-IV-8, P. and M. Becker coll. ( AEI). PARATYPES: 3♀♀, 1978-V-28–X-14, other data as holotype ( AEI).

DISTRIBUTION: Malaysia, Borneo.

ETYMOLOGY: From Greek, chryso, gold, and chaites, long hairs, referring to the conspicuous and golden-tinted body pubescence of the species.
