Genus Doratogonus Attems, 1914

Alloporus Porat, 1872: 43 ; 1876: 45; Saussure & Zehnter 1902: 175; Attems 1928: 346; 1950: 204; Schubart 1966: 90; Krabbe 1982: 113. Synonymised by Hoffman (1987).

Doratogonus: Attems 1914 a: 109 ; 1928: 339; 1934 b: 483; Schubart 1966: 90; Demange 1970: 401; Hoffman 1987: 13; Hamer 1998: 47; 1999: 10; 2000: 2; Hamer & Slotow 2000: 295.

Type species: Spirostreptus setosus Voges, 1878 .

Diagnosis: Mandible with 10–12 pectinate lamellae. Collum projects anteriorly ( Fig. 49). Lateral lamella of telocoxite with a small spine-like projection on lateral edge, median lamella typically setose and extended distally as a slender, spinous projection ( Fig. 47). Telopodite with long, slender shaft, curved proximally, with long, strongly curved femoral process, and with torsion of main branch of telopodite at position of origin of femoral process, distal to which main branch is looped ( Figs 47, 48). Solenomere distally forked or apically bifid ( Fig. 47).

Remarks: Attems (1914) erected Doratogonus as a new genus, but its differentiation from Alloporus Porat, 1876 , remained unclear. The two genera were separated only by the position of the first ozopore. Krabbe (1982) combined the generic concepts under Alloporus , but Hoffman (1987) revived the name Doratogonus for medium- to largesized spirostreptids which differ from Alloporus in having more pectinate lamellae on their mandibles and more numerous small setae on the distal half of the stipes. The genus Alloporus was placed on the list of genera incertae sedis. Hoffman (1987) considered Doratogonus to be heterogeneous and provided a diagnosis, which he believed was too inclusive ( Hamer 2000).
