Type species

Colombocricus tegua gen. et sp. nov., by present designation.

Other species included

Colombocricus fundipudens ( Karsch, 1881) gen. et comb. nov.

Diagnosis

Large spirobolidan, adults with 39–43 body rings plus telson, length 160–200 ( ♂) ( Figs 1 View Fig , 4 View Fig , 5A View Fig ) or 150– 185 mm ( ♀) ( Fig. 5B–C View Fig ), width 13–17 ( ♂) or 20 mm ( ♀), with scobinae and tarsal pads ( Fig. 1C View Fig ). The genus differs from other rhinocricids mainly in the male gonopods features: the coxite (cx) of the anterior gonopods is short and wide with the terminal edge almost transverse, the median corner elongated to a sharp point shorter than the sternite (st); the telopodite of the posterior gonopod is long, with an external branch (eb) spoon-shaped with an excavation on the femoral process and a solenomere (sl) bifurcated in two lanceolate processes ( Figs 2–3 View Fig View Fig , 6–7 View Fig View Fig ).

Etymology

The generic name is the union of ‘Columbus’, a general word in reference to ‘Colombia’, to which both species of the genus are restricted, and ‘- cricus’, a combining element frequently used in the formation of generic names of this family.

Distribution

Only known from Colombia ( Fig. 8 View Fig ).

Key to the species of Colombocricus gen. nov. (based on males)

1. General coloration greenish brown ( Fig. 1 View Fig ). Sternite (st) of the anterior gonopod tongue-shaped with smooth surface; distal edge of the coxite (cx) without a salience ( Figs 2A View Fig , 3A View Fig ). Solenomere (sl) of the posterior gonopod with the external branch (eb) spoon-shaped, dorsally covered the solenomere (sl) as a cupula, the external process (ex) shorter than external branch (eb) and inner process (in) almost invisible ( Figs 2C–D View Fig , 3B–C View Fig ) ......... Colombocricus fundipudens ( Karsch, 1881) gen. et comb. nov.

– General coloration reddish brown ( Figs 4 View Fig , 5A View Fig ). Sternite (st) of the anterior gonopod subtriangular with paramedian excavations in the basal portion; distal edge of the coxite (cx) with a salience ( Fig. 6A View Fig ). Solenomere (sl) of the posterior gonopod with the external branch (eb) with rounded lamella at the tip, the external process (ex) longer than the external branch (eb) and inner process (in) is visible ( Figs 6C–E View Fig , 7A View Fig ) .................................................
