Iphita rubricata albolutea subsp. nov.

Type material. HOLOTYPE: J, MALAYSIA: KALIMANTAN: SABAH: Danube Valley Reserve, Field Centre , 40 NV trap in 1° forest, 5°01′N 117°47′E, i.-iii.1994, W. R. Hynd lgt. ( BMNH).

Description. Colouration. Body mainly brown black. Head red, ventrally darkened along labial groove. Labial segment I basally blackish, rest of segment as well as entire segment II red, segment III darkend, segment IV black. Antennae black, only apical third of antennomere 4 whitish. Coxae, trochanters, bases and apices of femora, and tibiae basally narrowly red, remaining parts of legs black. Pronotal collar, entire callar lobe, median part of pronotal lobe, scutellum, clavus and corium (except of margins) brownish red. Membrane black, its margins widely pale grey. Lateral pronotal margin, pronotal epipleura, costal margin, hypocostal lamina, and dorsal and ventral laterotergites whitish yellow. Whitish-yellow colouration on lateral pronotal margins extended to margins of pronotal lobe, and on corium from costal margin up to median cleft; whitish-yellow colouration behind level of scutellar apex limited only to costal margin. Ventral side of body blackish brown, only prosternal collar red and posterior pleural flange III with reddish tinge.

Structure. Pronotal collar narrower in its entire width, less delimited from pronotal lobe; callar lobe only slightly gibbous; pronotal lobe distinctly elevated towards its posterior margin. Lateral pronotal margin distinctly concave at the level of median furrow. Posterior part of scutellum gibbous in lateral view. Body margins nearly parallel-sided. Profemora apically with four teeth on dorsal margin of longitudinal furrow and a row of small denticles (slightly larger before apex) on its ventral margin.

Pygophore. Ventral side of ventral wall medially strongly gibbous, with elongated small ridge heading towards ventral rim. Ventral rim strongly incrassate, medially broken, with shallow longitudinal furrow present under its incrassate part.

Punctation. Fine punctures laterally along callar lobe, on entire surface of pronotal lobe (except of its basal margin); scutellum in its anteromedian impressed part and clavus punctured; corium nearly without punctures.

Measurements (all in mm). Male (holotype). Body length 17.93; head: width (including eyes) 2.75, interocular width 1.40; lengths of antennomeres: 1 – 3.67, 2 – 3.29, 3 – 2.05, 4 – 4.16; pronotum: length 3.24, width 5.40; scutellum: length 2.43, width 2.97; corium: length 8.86, width 3.19.

Differential diagnosis. Iphita rubricata albolutea subsp. nov. is similar to the nominotypical subspecies in the structure of the pronotum ( STEHLÍK & JINDRA 2006b: Fig. 1 ) but is easily distinguished by the whitish-yellow colouration of the pronotal margin, costal margin, and laterotergites (red in the nominotypical subspecies). The apparently smaller size of I. r. albolutea subsp. nov. is due to the fact that the description is based on a male, while the description of the nominotypical subspecies is based on a female.

Etymology. The subspecies epithet is composed of the Latin adjectives albus (= white) and luteus (= yellow), referring to the diagnostic whitish-yellow colouration of the body margins.

Distribution. Malaysia, Kalimantan, Sabah state. Iphita rubricata rubricata is distributed in the Meghalaya state in north-eastern India ( STEHLÍK & JINDRA 2006b).
