A new species of Trichopseniini (Coleoptera, Staphylinidae) found with Schedorhinotermes termite (Isoptera, Rhinotermitidae) in Khao Yai National Park, Thailand Author Kanao, Taisuke Author Maruyama, Munetoshi Author Sakchoowong, Watana text Zootaxa 2011 2748 53 60 journal article 10.5281/zenodo.276668 d81dcc89-1077-493c-925e-6ced3099597a 1175-5326 276668 Schedolimulus komatsui Kanao & Maruyama , new species Type material. Holotype : THAILAND : 3, labeled “ Thai : Nakhon Nayok, Khao Yai National Park, Mo Sing To ( 700 m alt.), 28 IX 2007 , Maruyama M. and Katayama Y. leg.”, “ Holotype Schedolimulus komatsui des. Kanao & Maruyama, 2010”, abdomen dissected and mounted in Euparal. Palatypes: THAILAND : 4 3, 2 ƤƤ and 16 specimens with sex unknown, same data as the holotype . Diagnosis. This species is very similar to S. pumilio and S. minutus but easily distinguished from S . pumilio by the elytra being moderately, almost uniformly covered with setae, and from S . minutus by the lateral lobe of the male tergite IX with a large and curved macroseta.

Description. Body ( Fig. 2 ) almost uniformly orange brown, but elytra slightly darker. Dorsal surfaces of pronotum, elytra and abdomen smooth, shiny; elytra and abdomen sparsely covered with long yellow setae. Pronotum ( Fig. 9 ) sparsely covered with macrosetae except around mesal area. Meso- and metaventrites ( Fig. 10 ) sparsely covered by setae. Elytra ( Fig. 11 ) with 5 macrosetae on lateral margin. Fore leg ( Fig. 12 ) with femur sparsely covered with setae around apex; tibia sparsely covered with setae and with 3 spurs at apex; tarsus with 2–3 setae at apex of each segment. Mid leg ( Fig. 13 ) with femur sparsely covered with setae; tibia sparsely covered with setae that are becoming longer toward apex, with 3 spurs (1 smaller than others); tarsus with segment I sparsely covered by setae, with 2–3 setae at apex of each of segments II–IV. Hind leg ( Fig. 14 ) with femur covered with several setae, 1 long and thick macroseta at apex of inner margin; tibia with 7 long and thick spurs (1 apical spur longer than others) on outer margin and at apex, 3 spurs on inner margin; tarsus with segment I sparsely covered with setae, with 2–3 setae at apex of each of segments II–IV. Macrochaetotaxy of abdominal tergites III–VIII: 6, 4, 4, 4, 4, 4. Male . Abdominal tergite VIII ( Fig. 15 ) with 2 pairs of macrosetae, sparsely covered with setae; sternite VIII ( Fig. 16 ) with anterior margin deeply emarginated, basal projections much longer than in female, 3 pairs of macrosetae on lateral margins; lateral lobe of tergite IX ( Fig. 17 ) with a large macroseta ( Fig. 17 : arrow) around middle, which is curved inward at middle, with a row of about 6 macrosetae. Median lobe of aedeagus ( Fig. 21–22 ) with apical lobe slightly curved paramerally in lateral view, narrowed toward apex in dorsal view; apical part of apical lobe well sclerotized; distal crest well produced. Paramere ( Fig. 23 ): apical lobe curved, with 2 long macrosetae (1 near base, 1 apex). Female . Abdominal tergite VIII ( Fig. 18 ) smaller than in male, with 2 pairs of macrosetae and covered with setae; sternite VIII ( Fig. 19 ) smaller than in male, with 3 pairs of macrosetae on lateral margins; lateral lobe of tergite IX ( Fig. 20 ) narrowed posteriorly, much smaller than in male, with 6 macrosetae on lateral margin. Spermatheca ( Fig. 24 ) with apical part swollen, and its inner wall sparsely wrinkled; basal part twice as long as apical part and slightly curved near apex. Measurements. Body length: ca. 1.1–1.2; antennal length: 0.19–0.23; pronotal length: 0.37–0.39; pronotal width: 0.62–0.68; elytral length: 0.32–0.38. N=5. Symbiotic host. Schedorhinotermes medioobscurus ( Holmgren, 1914 ) . Etymology. Dedicated to Dr. T. Komatsu who helped the second author (MM) in his field research.
