Eutrichodesmus simplex View in CoL sp. n.
Figs 3–5 View FIGURE 3 View FIGURE 4 View FIGURE 5
Material: Holotype male (SCAU), China, Jiangxi Prov., Fenyi County, Taoyuan Dong, 0 1.10.2012. leg. Tian Mingyi (CHIjx12-LWX01). Paratypes: 2 males, 1 female (IZAS), 2 males, 1 female (ZMUM), 7 males, 3 females, 6 juv. (SCAU), same locality, together with holotype.
Name: To emphasize the rather simple gonopod acropodite.
Diagnosis: Differs from congeners by the metaterga behind the collum supporting three transverse isostictic rows of large, rounded, setigerous tubercles, and the gonopod telopodite carrying a conspicuous, microtuberculate, distofemoral process (dp) at about midway and a rather simple acropodite.
Description: All characters as in E. digitatus sp. n., except as follows.
Length of adults of both sexes ca 8.0- 9.5 mm, width 1.8-2.5 mm. Holotype ca 9.0 mm long and 2.5 mm wide. Coloration uniformly pallid or light yellowish ( Figs 3 View FIGURE 3 , 4 View FIGURE 4 A).
Antennae rather long and slender. Collum semi-circular, evidently flattened mid-dorsally, entire surface microvillose, with five irregular transverse rows of round tubercles ( Fig. 3 View FIGURE 3 C). Metaterga behind collum with three transverse isostictic rows of large, rounded, setigerous tubercles ( Figs 3 View FIGURE 3 A-B, D), two frontal rows being highest and best expressed in ♀. Paraterga 2 strongly enlarged, subvertical, with a series of lobulations anterolaterally; paraterga 3 and 4 slightly shorter than others, each with three lobulations anterolaterally, overlap of following paraterga typical ( Fig. 3 View FIGURE 3 B). Paraterga 8 and following paraterga quadrilobulate ( Fig. 3 View FIGURE 3 D, E). Pleurosternal ridges present in segments 2 and 3 (♂, ♀).
Sterna between ♂ coxae 6-7 and 9 much wider. Legs long and slender, barely reaching tips of paraterga; femora and tarsi longest, subequal in length; some setae with microdenticulations ( Fig. 3 View FIGURE 3 E).
Gonopods ( Figs 4 View FIGURE 4 B-D, 5A-B) very simple. Coxae subquadrate, large, microtuberculate and abundantly setose ventrolaterally. Telopodite longer than coxite, slender throughout, setose in its basal half, with a conspicuous, microtuberculate, distofemoral process (dp) at about midway. Acropodite erect, rather simple, devoid of a hairpad; seminal groove terminating subapically.
Remarks: This is a typical “doratodesmid”, possibly a troglobite.
