Tylopus Jeekel 1968

Genus Tylopus Jeekel, 1968 Agnesia Attems, 1953: 174. Tylopus Jeekel, 1968: 60. Paratylopus Korsós & Golovatch, 1989: 215. TYPE SPECIES. — Agnesia nodulipes Attems, 1953, by original designation. EMENDED DIAGNOSIS. — Body medium-sized to large (c. 10-44 mm long, c. 0.5-5.1 mm wide), with 20 segments. Paraterga from virtually missing to strongly developed, usually with lateral incisions. Transverse metatergal sulcus distinct. Leg relatively long and slender, most species present adenostyles (= ventral outgrowths) at least on some of the male legs. ♂ tarsal brushes usually present. A sternal lobe between ♂ coxae 4 present. The gonopod telopodite typically features a prominent transverse ring, or cingulum, demarcating the postfemoral region which starts at the base of a free, flagelliform solenomere. This solenomere is largely sheathed by a slender, sigmoid solenophore that often bears basal outgrowths. The cingulum is rarely incomplete, usually due to a reduced sulcus at the base of a postfemoral lobe l. While lobe l itself is usually simple, sometimes it can be crowned with an additional outgrowth or process. Beyond lobe l, the postfemoral region usually possesses a medially positioned process h. Additional disto- and/or postfemoral outgrowth appearing even more sporadically is process z, more variable, albeit occasionally reduced or even absent. Only a few species show particularly complex gonopods, where not only is the postfemoral region supplied with a long, spiniform process z, but also with a small to elongated, knife- or spine-shaped outgrowth m on the distodorsal portion of the femorite (Golovatch & Enghoff 1993; Likhitrakarn et al. 2010). REMARK Full reviews of this genus were performed by Golovatch & Enghoff (1993) and Likhitrakarn et al. (2010).
