Haris, A.: Allantinae, Selandrinae and Heterarthrinae from Laos 109 It is also similar to Neothrinax achterbergi Haris, 2008. However, Neothrinax achter- bergi Haris is much smaller, only 4.0 mm and basal antennal segments are white. Ridgea laoensis spec. nov. (Figs. 22 and 33) Holotype: female, Phongsaly prov., Phongsaly, 21°41-42'N, 102°06-08'E, 1500 m, May-June 2003, leg. Kubán. Body black; white: prepectus, tegula, scape, pedicel, basal spot on 3rd antennal segment, abdominal stemites 1-6 and cenchri. Legs white, black: apical half of middle and hind tibiae, small apical spot on anterior femora, apical quarter of middle and hind femora, apical segment of tarsi. Wings hyaline, costa, subcosta, veins and stigma brownish black. Ratios of antennal segments 1-9: 9 : 4 : 19 : 19 : 15 : 10 : 9 : 9 : 10. Antenna as long as head, thorax and first 3 abdominal tergites combined. Temples and vertex moderately densely and moderately deeply punctured, hardly shiny. Frontal area very densely punctured, matt. Pentagonal frontal area missing. Eyes connected by a horizontal supraantennal ridge (genus Ridgea Saini and Saini 1996). Gena linear. Postoccipital carina short, reaching up to 1/3 of eye. Clypeus shallowly emarginated. Temples behind eyes contracted and about as wide as length of pedicell. Anal cell of fore wing with crossvein. Anal cell of hind wing petiolate. Anterior wing with 2 cubital cells. First cubital crossvein missing. Basalis and first recurrent vein contracted. Hind wing with 2 closed middle cells. Mesonotal lobes with moderately deep and moderately large, sparse punctures, moderately siny. Mesoscutellum with small, moderately deep punctures, moderately shiny. Mesoscutellar appendage and metascutellum smooth and shiny. Mesopleuron smooth and shiny. First abdominal tergite (propodeum) smooth and shiny, others with granulated surface sculpture, hardly shiny. Claws with large subapical tooth without basal lobe, subapical tooth shorter than apical (Fig. 22). Length of inner hind tibial spur: length of hind basitarsus: 15 : 49. Ovipositor very short, apex of ovipositor hardly visible above. Length: 6.6 mm. The new species related to Ridgea kalatopensis M.S. Saini & T.P. Saini, 1996. Ridgea kalatopensis has first 2 abdominal tergites and stemites reddish brown, femora are entirely white. The new species has tergites black and stemites 1-6 white. Femora with black spots. Inner tooth of claws are small in R. kalatopensis (as it figured in Saini and Saini 1996) but large in the new species. Taxonus laoensis spec. nov. (Figs. 3, 13, 24 and 34) Holotype: female, Hua Phan Prov., Ban Saleui, Phou Pan Mt., 20°13'30"N, 103°59'26"E, 1350-1900 m, 14-18. 04. 2010, leg. C. Holzschuh and locals. Head and antenna black; white: labrum, palpi, middle part of mandible and 4 apical antennal segments. Thorax black; tegula and hind mesonotal margin light brownish white. Cenchri brown. Abdomen black, tergites 3-4 reddish yellow, tergite 3 with 2 large brown spot. Next 3 tergites with reddish basal margin. Stemites 1 -5 reddish yellow. Legs reddish yellow, apical 2/3 of hind femora black. Wings hyaline, costa, subcosta, veins and stigma blackish brown, apical half of costa yellowish brown. Ratios of antennal joints 1-9: 11 : 5 : 37 : 27 : 25 : 21 : 18 : 17 : 20. Head subparallel behind eyes, temples behind eyes as wide as length of 8th antennal segment. Head moderately sparsely punctured with moderately large and shallow punctures, shiny. Frontal area moderately
