Description. Colouration (Fig. 18). Black colour on head, antennae (except of slightly more than apical half of antennomere IV which is white), callar lobe, large oval median and smaller oval apical spot on corium, legs, sternum, ventrites (except of laterotergites), and membrane (except of slightly paler veins). Pronotal lobe and scutellum (except of apex) darkened. All pronotal margins, scutellar apex, clavus and corium, anal vein, postcubital vein and claval comissure on clavus, cubital vein on corium, and costal margins yellowish; both clavus and corium basally and between median and apical spot darker. Anterior margin of callar lobe reddish. Labium pale reddish or black.

Structure. Body large and robust; antennae and legs stout. Antennomere 1 shorter, distinctly widening towards apex. Profemora in both sexes very stout, dorsal margin of longitudinal furrow with indicated denticles along its entire length, only apically with two strong teeth; ventral margin of longitudinal furrow along its entire length with medium-sized, somewhat curved teeth and small denticles. Meso- and metafemora ventrally along its entire length with shallow, wider impression, bordered on both sides with small denticles (slightly smaller in females). Labial segment I not approaching head base. Callar lobe strongly gibbous in both sexes; pronotal lobe nearly flat, with indicated median longitudinal ridge.

Pygophore. Ventral wall nearly flat, ventral rim nearly horizontally inclined into genital chamber, with bowl-shaped depression, medially ridge-like gibbous. Lateral rim rounded, median part of lower margin of lateral rim infolding elevated dorsally. Paramere stout, basally almost parallel-sided, outer side distinctly incrassate, apically narrowed, round and straight, apex rounded; the opposite side under the narrowed apical part distinctly arcuately gibbous (Fig. 15).

Punctation. Pronotal lobe, scutellum, clavus and corium with distinct black and coarse punctures, those on pronotal lobe and scutellum uniformly dense. Costal margin of corium impunctate.

Pilosity. Dorsal surface of body covered with black erect hairs, only posterior pronotal margin with row of horizontal pale hairs. Ventrites with pale adpressed and longer erect hairs.

Measurements (all in mm). Males (n = 5). Body length 14.03 (12.80-14.85); head: width (including eyes) 2.15 (2.07-2.24), interocular width 1.36 (1.27-1.43); lengths of antennomeres: 1 – 2.13 (2.00-2.21), 2 – 2.40 (2.21-2.54), 3 – 1.63 (1.57-1.67), 4 – 2.60 (2.43-2.75); pronotum: length 3.00 (2.70-3.40), width 4.39 (4.10-4.75); scutellum: length 2.14 (1.97-2.38), width 2.61 (2.48-2.97); corium: length 7.20 (6.86-7.67), width 2.51 (2.43-2.62).

Females (n = 5). Body length 14.19 (13.55-14.63); head: width (including eyes) 2.18 (2.08-2.24), interocular width 1.41 (1.35-1.46); lengths of antennomeres: 1 – 1.94 (1.57-2.11), 2 – 2.33 (2.16-2.48), 3 – 1.61 (1.40-1.73), 4 – 2.64 (2.54-2.70); pronotum: length 2.79 (2.56- 2.97), width 4.39 (4.10-4.59); scutellum: length 2.15 (1.94-2.29), width 2.43 (2.16-2.75); corium: length 7.19 (6.80-7.67), width 2.46 (2.29-2.59).

Differential diagnosis. The new species is related to Physopelta cincticollis Stål, 1863 (Fig. 19), which is widely distributed from eastern India to Japan, Korea, Taiwan, and Sumatra (KERZHNER 2001, STEHLÍK 2005a) and differs from Ph. kotheae sp. nov. by its smaller size, distinctly slender antennae and legs. Additional characters that can distinguish the two species are as follows: antennomere 1 slender and regularly widening towards apex in Ph. cincticollis (stouter and distinctly widened apically in Ph. kotheae sp. nov.); apices of profemora with two medium-sized, well separated teeth ventrally (with two large teeth placed side-by-side in Ph. kotheae sp. nov.); distinctly slender tibiae with more slender spines (stout with very conspicuous spines in Ph. kotheae sp. nov.); anterior portion of pronotum much narrower, callar lobe less gibbous, lateral margins of pronotum from the level of pronotal lobe distinctly widening towards pronotal base, especially in females (pronotal margins less widening posteriorly in Ph. kotheae sp. nov.); longitudinal furrow on meso- and metafemora much narrower; paramere of Ph. cincticollis as in Fig. 16.

Etymology. Named in honour of Tanja Kothe (ZSMC), the collector of the holotype.

Distribution. Indonesia, Sumatra and Java.
