Salcedia parallela Baehr, 1998: 2; Lorenz 2005: 155.

Type material.

Holotype: ♀, with labels and data: yellow, black printed and handwritten in black ink "BURMA (central) Mandalay, 20.9. 1984 D. Grohmann leg." / red, black printed "HOLOTYPE Salcedia parallela sp. nov. det. M. Baehr 1997" (SMNS).

Remark.

The tarsomere of the right intermediate leg are missing.

Diagnosis.

A large sized species, with oblong-elongate outline of the elytra with maximum width at middle and the pronotum with three additional carinae of which the inner lateral carina is shortened to a rudiment and the outer one anteriorly shortened. The pseudohumerus is rectangular and with a distinct tooth. The antennomeres are elongate. Distinguished most clearly from the similar species S. miranda by the pronotum with the lateral margin straight and parallel and with eleven indistinct tubercles. Moreover, in S. parallela the interneur five and six of the elytron shows three rows of pits at middle.

Redescription.

Measurements in Table 1 View Table 1 .

Colour and surface: Anthracite grey with piceous traces, shiny; carinae of pronotum and elytra as well as margins of pronotum and elytra and surface of supra-antennal and supraorbital plates densely covered with beige-grey pili; legs, mandibles and scapus of antennae fuscous, other antennomeres lighter apically, palpi leoninous.

Head: Five-sixths of width of pronotum. Outline semi-circular. Clypeus wide, straight anteriorly, fused with clypeal wings, separated from supra-antennal plates by indistinct obtuse notches and deep pit at each side, with raised oval-shaped field at middle, separated from frons by broad transverse furrow. Frons with two raised paramedian carinae, carinae convex, not joining anteriorly, with two small glossy teeth bilaterally to median carinae, with two shorter diverging carinae paralaterally at base; frons separated from supraorbital plates by deep broad furrows; with conspicuously broad pit at front-eye level; supra-antennal and supraorbital plates keel-like raised, supra-antennal plates vaulted. Base with angled emargination at middle (angle 130°), laterally obtuse angled (angle 102°). Eyes large, convex, genae higher as eyes, convex, both of them just visible from above, in lateral view shaped like a broad strip. Antenna with segments five to ten elongate (L/W 1.22), densely pubescent, segments two to four scarcely pubescent, scapus with longitudinal reticulation. Labrum straight anteriorly. Mandible moderately short, wide, slightly arcuate at apex. Mentum of moderate size, oval, epilobes wide, projecting, acutely angled anteriorly, with flattened margin at base, inner side and anteriorly, surface with longitudinal flat pits.

Pronotum (Fig. 43 View Figures 36–43 ): Outline rectangular, transverse, a third wider than long. Lateral margin almost straight, maximum width in middle third. Lateral margin crenulated, with eleven small tubercles larger basally, with notch at each posterior angle. Base straight laterally, with obtuse keel at middle pointing posteriorly. Disc nearly flat in lateral view, with two raised paramedian carinae parallel to median line and diverging posteriorly, with median line narrow, long, and ending in pits anteriorly and posteriorly, with four additional shorter carinae bilaterally, the paralateral one joining with the paramedian carinae at base and forming tooth-like tubercle pointing posteriorly and fringed with fine setae, extended anteriorly as less raised paralateral carina. With inner lateral carina very short, not connected to long outer lateral carina. All carinae sub-crenulate. Lateral margin broadly wing-like bent up, with six large and deep transverse pits existing of partly connected circular pits, the frontal one partly situated directly at the frontal margin and separated from the second one by a conspicuous ridge.

Elytron: Flattened in anterior half (lateral view), moderately convex in frontal view. Oblong-elongate, margin straight in middle third, maximum width at middle, sub-tuberculate. Pseudohumerus rectangular (slightly over 90°), with distinct tooth. Apex rounded, with small but acute tooth at suture. Disc with interneur six sub-tuberculate, interneur three with indistinct longitudinal convexity at base, interneur two running towards apex as convex line, conspicuously raised, week apically, almost reaching apex; interneur four running in parallel to interneur two, almost reaching base, shortened at apex. Interneur five and six with three rows of serial pits. Pits of interneurs five and six partly connected transversally.

Hind wings: Fully developed.

Lower surface: Antennal channel of pronotum with surface irregular reticulated. Pseudoepipleura densely covered with grey pili, with partly doubled row of circular pits, lateral margin of elytron smooth. Metepisternum elongate, with broad longitudinal reticulated groove. Metasternum, abdominal sternites one to five with numerous irregularly situated smaller and larger pits, sternites four to six sulcate, four and five with band of small punctures at middle. Sternum six bilaterally slightly hollowed out concavely, with blunt longitudinal carina at middle.

Legs: Profemora with dorsal surface irregularly reticulated. Protibia with moderately long and distinctly laterally curved terminal spine, laterally bidentate and with two strong setae towards base, dorsally and ventrally with two carinae. First tarsomere distinctly elongated, nearly as long as tarsomeres two to five together.

External sexual dimorphism: Not observed.

Male genitalia: Unknown.

Female genitalia (Fig. 83 View Figures 77–83 ): Coxostylus distinctly slender, obtusely and regularly curved, distinctly acute at apex, at end of basal third with one large and seven slender nematiform setae laterally, SSO with one fine pilus.

Variation: Intra-individually, one side of the pronotum is straight and the other indistinctly convex.

Distribution
