The assmuthi View in CoL species group

Diagnosis. The assmuthi group is defined by the following character states: 1) mandible ( Figs. 57, 58 View FIGURES 54 – 72 , 76, 77 View FIGURES 73 – 88 , 92, 93 View FIGURES 89 – 104 , 108, 109 View FIGURES 105 – 120 , 124, 125 View FIGURES 121 – 136 , 140, 141 View FIGURES 137 – 148 , 152, 153 View FIGURES 149 – 164 ) covered with 15–40 pores, 2) maxillary basistipes ( Fig. 59 View FIGURES 54 – 72 ) almost fused with palpifer, 3) sternite VIII ( Figs. 66, 67 View FIGURES 54 – 72 , 82, 83 View FIGURES 73 – 88 , 98, 99 View FIGURES 89 – 104 , 114, 115 View FIGURES 105 – 120 , 130, 131 View FIGURES 121 – 136 , 146 View FIGURES 137 – 148 , 158, 159 View FIGURES 149 – 164 ) sparsely covered with minute pores anteriorly, 4) tergite X ( Figs. 68 View FIGURES 54 – 72 , 84 View FIGURES 73 – 88 , 100 View FIGURES 89 – 104 , 116 View FIGURES 105 – 120 , 132 View FIGURES 121 – 136 , 147 View FIGURES 137 – 148 , 160 View FIGURES 149 – 164 ) with posterior half covered with a batch of setae, 5) median lobe of male aedeagus with basal capsule small (Figs, 69, 85, 101, 117, 133, 161), and 6) basal capsule of male aedeagal median lobe with distal crest strongly developed ( Figs. 70 View FIGURES 54 – 72 , 86 View FIGURES 73 – 88 , 102 View FIGURES 89 – 104 , 118 View FIGURES 105 – 120 , 134 View FIGURES 121 – 136 , 162 View FIGURES 149 – 164 ).

Comments. The assmuthi species group includes 11 species: D. assmuthi Wasmann, 1904 , D. lepisma Wasmann, 1904 , D. indicus Kistner, 1982 , and D. malaysiensis Kistner, 1982 , D. phourini n. sp., D. kohkongensis n. sp., D. hirsutus n. sp., D. minutus n. sp., D. lucidus n. sp., D. kakizoei n. sp., and D. katayamai .

The affiliation of the four previously known species, D. assmuthi , D. lepisma , D. indicus , and D. malaysiensis , are determined based on the character states of their mouthparts and/or male aedeagus ( Kistner 1982), and expected to share other character states typical of the species group.
