description: <i>Koenikea</i> (<i>Notomideopsis</i>) <i>longiseta</i> n. sp. Zoobank: 36129DB3-0405-44B4-8A90-5EC8AE426BE7 (Figure 13 A-F) <b>Material examined</b> — Holotype male, Kent River at crossing with South Coast Highway, Western Australia, Australia, 34°57.576′ S 117°02.430′ E, 25 m asl, 19 Apr. 2008 (WAM). Paratypes: two females, Rowell’s Pool, Mount Frankland South NP, Western Australia, Australia, 34°49.120′ S 116°35.657′ E, 34 m asl, 6 Feb. 2019 (WAM). <b>Diagnosis</b> — Idiosoma reddish with yellow spot, setae of dorsum and venter relatively long, apodemes of anterior coxae short, gonopore of male wide. <b>Description</b> — Male: Idiosoma reddish with yellow spots, dorsally 494 long and 470 wide, ventrally 454 long. Dorsal shield 470 long and 413 wide, with six pairs of glandularia with relatively long associated setae. Dgl-3 and Dgl-4 closer to each other than Dgl-5 and Dgl-6; Dgl-5 distanced from lateral margin of dorsal shield (Figure 13A). Apodemes of anterior coxae extending onto Cx-III. Setae of coxae relatively long, those of Cx-IV nearly as long as length of Cx-IV. Cxgl-4 lying close to posterior margin of Cx-IV (Figure 13B). Gonopore 51 long and 34 wide, relatively wide, with eight pairs of acetabula. Between the acetabula a pair of glandularia. Length of P1-5: 18, 52, 25, 57, 22. P4 with a short anteroventral tubercle (Figure 13C). Length of I-leg-4-6: 76, 92, 116. First leg with relatively short and narrow grooved or fluted setae (Figure 13D). Length of IV-leg-4-6: 108, 136, 122. IV-leg-5 with two swimming setae, IV-leg-4 with three swimming setae (Figure 13E). Female: Idiosoma colour as in male, dorsally 567 (583) long and 535 (535) wide, ventrally 535 (526) long. Dorsal shield 518 (547) long and 462 (462) wide; configuration of dorsal glandularia as in male. Coxae, including long setae, as in male. Gonopore 116 long and 114 wide. Genital field with eight pairs of acetabula; between the acetabula a pair of glandularia (Figure 13F). Length of P1-5: 22, 58, 27, 56, 22. Length of I-leg-4-6: 92, 104, 110. Length of IV-leg-4-6: 90, 124, 132. Legs as in male. All legs with swimming setae. I-leg-4 with one swimming seta, I-leg-5 with two swimming setae, IV-leg-3 with one, IV-leg-4 and IV-leg-5 with three swimming setae <b>Etymology</b> — Named for its long coxae and dorsal setae. <b>Remarks</b> — The only other <i>Koenikea</i> species with long coxal setae is <i>K. crinita</i>. The latter species is much larger males (dorsal shield 562-805), Dgl-5 are more separated from each other and the genital field has more acetabula. Like <i>K. curtiseta</i> Cook, 1986 the new species has the first leg with short grooved setae, but the former is larger (dorsal shield 623) has a genital field with more acetabula and Dgl-5 are more distanced from each other.
