Listrodromus javae HEINRICH 1975 , new

M a t e r i a l: Laos, Bolikhansai province, Ban Nape environment, 350 m, 18°20´N 105°08´E, 1 7- 16.v.2004, leg. Jendek & Sausa ; Laos, Phongsaly province, 21°41´N 102°6`E, Phongsaly environment, ca. 1500 m, 1 6-17.v.2004, leg. Vit Kuban (Linz) .

D e s c r i p t i o n:

Body length 7.5 mm. Flagellum short, filiform, somewhat thickened beyond middle, with 20 flagellomeres, first flagellomere (without anellus) about 3.2-3.5 times as long as wide, preapical flagellomeres square. Frons, vertex and gena almost smooth and strongly shining, face and clypeus with small scattered puncture, clypeus almost smooth apically. Malar space almost 2 times as long as the width of mandibular base.

Mesosoma shining. Pronotum punctured in front and smooth behind the distinct epomia, upper margin thickened, with scattered puncture. Notauli distinct on the anterior border, mesoscutum with puncture in the anterior third, otherwise smooth and shining, Mesopleura and metapleura with dense puncture or puncture-striation, speculum very large, smooth. Prepectal and coxal carinae strong, with transverse ribs, sternauli impressed in the anterior third of mesopleura. Scutellum moderately elevated, transverse, with lateral carinae in the basal 0.8, with scattered puncture. Propodeum with complete carination, spiracles oval (index about 1.5). Area superomedia and areae superoexternae smooth, propodeum with strong puncture elsewhere. Coxae with dense puncture, hind coxa without scopa. Hind femur club-shaped, about 3.1 times as long as high. All claws with 4-5 strong teeth.

Areolet slightly narrowed in front, minimal distance of intercubiti about 4-5 times their width, 2m-cu reaching the areolet before its middle. Nervulus of front wing interstitial.

Metasoma amblypygous. Postpetiole moderately widened to the apex, without distinct dorsal carinae and with scattered puncture. Second tergite elongate, about 1.2-1.3 times as long as wide, third tergite almost square, gastrocoeli square, thyridia small, transverse, each about 0.6-0.7 times as wide as their interval ( fig. 3 ), second tergite with coarse puncture in the basal half and very fine and scattered puncture in the apical one. Third and fourth tergites with scattered puncture basally, otherwise like the following tergites smooth and shining.

Colour black. Yellowish are face (except a black longitudinal stripe in the middle), frontal orbits, large spot on the upper outer orbit, scape beneath, upper margin of pronotum, subalar ridge, base of wings, scutellum, often postscutellum, dorsolateral spots on postpetiolus and tergite 2, apical band of third tergite, apical spots on tergites 4-7, front and middle coxae and trochanters, dorsal and ventral spots on hind coxa. Legs and tergites 1 and 2 red.

Taxonomical remark: The taxon has been described from Java by HEINRICH (1934: 243) as the male of Listrodromus simplex , but was renamed as L. javae in a subsequent publication (HEINRICH 1975: 459). I was not able to study the type material, but the characteristic coloration and structure, especially the very long malar space and second tergite, convinced me that the above described females belong to this particular species.
