Stenus electrigemmatus View in CoL nov.sp. ( Figs 19 View Figs 11-25 , 30 View Figs 26-45 )
T y p e m a t e r i a l: Holotype: TAIWAN: Kaohsiung Hsien: Peinantashan trail, 2500 m, 4.VII.1993, leg. A. SMETANA (T 136): in coll. SMETANA (Ottawa).
D e s c r i p t i o n: Micropterous, black with a faint brownish hue, elytra with very large, oval, orange spots (fig. 30), moderately shiny, forebody very coarsely and very densely punctate, abdomen coarsely and densely punctate anteriorly, moderately finely and moderately densely punctate posteriorly; pubescence short, recumbent. Antennae reddish, club infuscate. Maxillary plapi yellowish red, segment 3 infucate. Paraglossa oval. Legs reddish yellow, tarsal segments darker. Clypeus black, labrum dark brown, sparsely pubescent.
Length: 6.5 mm (extended) (forebody: 2.6 mm).
PM of the HT: HW: 44; DE:; 25; PW: 32; PL: 38; EW: 41; EL: 44; SL: 32.
M a l e: similar to S. electrigemmeus but the apical ermargination of sternite 8 a little narrower and deeper about one tenth as long as the sternite). Aedeagus similar to S. electrigemmeus , but the apicoventral area of short setae extremely dense (fig. 19), the apical setae longer and more numerous and the internal structures stronger sclerotized proximately.
F e m a l e: Unknown.
In most respects similar to S. electrigemmeus , but the median portion of frons only slightly elevated, not extending to the level of dorsal eye margins, and the punctuation somewhat coarser and very dense throughout. Pronotum and elytra very coarsely punctate, punctures as large as apical cross section of antennal segment 1, interstices smaller than half diameter of punctures. Elytral spot larger (EW; SL = 44: 31), extending to the posterior margin of each elytron. Punctation of the abdomen a little coarser and denser than in S. electrigemmeus : on tergite 4 punctures are as large as basal cross section of antennal segment 3, interstices on the average smaller than punctures; on tergite 7 punctures are about as large as eye facets near dorsal eye margin, interstices distinctly but not much larger than punctures.
C o m p a r a t i v e n o t e: Since the range of variability of S. electrigemmeus is unknown, the specimen described here has to be regarded as a distinct species because of differences in the aedeagus, of the coarser punctuation and of the larger elytral spot.
