Subgenus Indoceoplanetes Gustafsson & Bush, new subgenus

Type species. Same as for genus.

Diagnosis. Apart from the characters listed above, members of the subgenus In. ( Indoceoplanetes) can be separated from members of Maculinirmus, Turdinirmus, Titanomessor and Indoceoplanetes (Capnodella) as follows:

From Maculinirmus by the dorsal preantennal suture present and interrupting marginal carina at least submedianly in Maculinirmus (Figs 198, 205), but suture absent and marginal carina uninterrupted in In. ( Indoceoplanetes) (Fig. 219); male In. ( Indoceoplanetes) (Fig. 217) with tps on tergopleurites IV–VIII, but no tps on any segment in Maculinirmus (Figs 196, 203); mesosomal lobes with rugose nodi in In. ( Indoceoplanetes) (Fig. 221), but without rugose nodi in Maculinirmus (Figs 200; 207).

From Turdinirmus by the dorsal preantennal suture present and interrupting marginal carina at least submedianly in Turdinirmus (Figs 184, 191), but suture absent and marginal carina uninterrupted in In. ( Indoceoplanetes) (Fig. 219); male In. ( Indoceoplanetes) (Fig. 217) with tps on tergopleurites IV–VIII, but no tps on any segment in Turdinirmus (Figs 182, 189); mesosomal lobes with median dorsal point in In. ( Indoceoplanetes) (Fig. 220), but without such point in Turdinirmus (Figs 185, 192); rugose area of the distal mesosome is not restricted to the submedian section in In. ( Indoceoplanetes) (Fig. 221) as it is in Turdinirmus (Figs 186, 193); gonopore flares proximally in Turdinirmus (Figs 186, 193), but not in In. ( Indoceoplanetes) (Fig. 221).

From Titanomessor by the dorsal preantennal suture absent in In. ( Indoceoplanetes) (Fig. 219), but present in Titanomessor (Fig. 212); mesosome with median dorsal points in In. ( Indoceoplanetes) (Fig. 220), but without such points in Titanomessor (Fig. 213); rugose nodi present on mesosome in In. ( Indoceoplanetes) (Fig. 221), but absent in Titanomessor (Fig. 214); multiple sts and tps present on male abdominal segments IV–V in In. ( Indoceoplanetes) (Fig. 217), but absent in Titanomessor (Fig. 210).

From In. (Capnodella) by the dorsal preantennal suture absent in In. ( Indoceoplanetes) (Fig. 219), but present in In. (Capnodella) (Figs 226, 233); marginal carina uninterrupted in In. ( Indoceoplanetes) (Fig. 219), but interrupted submedianly in In. (Capnodella) (Figs 226, 233); tps present on at least some male tergopleurites in In. ( Indoceoplanetes) (Fig. 217), but absent on all tergopleurites in In. (Capnodella) (Figs 224, 231); both sexes with multiple sts on each side on at least segments IV–V in In. ( Indoceoplanetes) (Figs 217–218), but with multiple sts only on segment VI in In. (Capnodella) (Figs 224–225, 231–232).

Description. Both sexes. Approximately 1.5 times as long as Guimaraesiella and In. (Capnodella) on same hosts. Head flat-dome shaped (Fig. 219) with flattened or (in undescribed species) slightly concave frons. Marginal carina uninterrupted, often widened at osculum. Dorsal preantennal suture and dorsal anterior plate absent. Preantennal nodi slender, pointed. Ventral anterior plate absent. Thoracic and abdominal segments as in genus description (Figs 217–218). Re-entrant heads moderate. Abdominal chaetotaxy as in Table 2; tps present on male tergopleurites IV–VIII. Both sexes with multiple sts on each side on at least some abdominal segments.

Male. Mesosomal lobes with serrated or papillate posterior margins, 2 pmes microsetae on each side (Fig. 221).

Female. Vulval margin with very few or no vss (Fig. 223).
