China: Zhejiang: ♂, glued on a card with labels as follows: “ China: Zhejiang Province, Jinhua City, Shuanglongdong , 29°12'05''N, 119°37'12''E, alt. 263m, mixed forest leaf litter, sifted, 18.V.2018, Puthz, Tang, Cheng & Shuai leg.” “ Holotype / Stenus communicatus / Tang & Jiang” [red handwritten label] ( SHNU) GoogleMaps . Paratypes. 2♂ 7♀♀, same data as for the holotype ( SHNU, cPut) GoogleMaps .
Description. Brachypterous. Head black with clypeus and labrum dark brown, pronotum brownish, elytra light reddish brown, abdomen brownish with last four segments slightly darker. Antennae reddish brown with club infuscate, maxillary palpi and legs reddish yellow.
BL:2.5–3.0 mm, FL: 1.5–1.6 mm. HW: 0.67–0.69 mm, PL: 0.50 mm, PW: 0.50–0.52 mm, EL: 0.50–0.53 mm, EW: 0.60–0.62 mm, SL: 0.34–0.35 mm. Head 1.09–1.11 times as wide as elytra, pronotum 0.96–1.01 times as long as wide, elytra 0.82–0.85 times as long as wide.
Similar to S. qingliangfengus sp. nov. in most respects, but different in the following characters: head 1.09– 1.11 times as wide as elytra, punctation of head same in size; pronotum 0.96–1.01 times as long as wide; elytra 0.82–0.85 times as long as wide; abdominal segment III with very narrow paratergites.
Male. Sternite VII with posteriomedian portion flattened, posterior margin of flattened portion slightly emarginated; sternite VIII ( Fig. 13 View FIGURES 13–18 ) roundly emarginated at middle of posterior margin; sternite IX ( Fig. 14 View FIGURES 13–18 ) with long apicolateral projections, posterior margin serrate and slightly emarginated. Aedeagus ( Figs. 15, 16 View FIGURES 13–18 ) stout; apical sclerotized area of median lobe subtriagular and roundly pointed at apex; expulsion clasps large, strongly sclerotized; parameres longer than median lobe, widest at apcial third and gradually tapering apicad, each paramere with 6 subapical setae and 4–5 basal setae on apico-internal margins.
Female. Sternite VIII ( Fig. 17 View FIGURES 13–18 ) prominent at middle of posterior margin; spermatheca ( Fig. 18 View FIGURES 13–18 ) sclerotized with basal duct more strongly sclerotized, spermathecal duct bent twice with first duct long and straight, second duct short, and third duct curved.
Distribution. China (Zhejiang).
Remarks. The species resembles S. micuba Hromádka, 1982 from Jiangsu, S. hlavaci Puthz, 2003 from Jiangxi, S. breviculus Tang, Li & Puthz, 2010 from Zhejiang, S. pseudomicuba Tang, Puthz & Yue, 2016 from Zhejiang and S. qingliangfengus sp. n. from Zhejiang, but can be distinguished from them by abdominal segment III with complete paratergites; the species also resembles S. dongbaishanus Tang, Liu & Zhao, 2017 from Zhejiang, but can be distinguished from it by pronotal and elytral punctation more confluent.
Etymology. The specific name “ communicatus ” means participate.
