Hapalotremus chespiritoi   sp. nov.

( Figures 23–26 View Figure 23 View Figure 24 View Figure 25 View Figure 26 , 37 View Figure 37 )

Type material

Male holotype ( MUBI) from Peru, Canchis, Cusco, Sicuani , between Usicayos and Quetapalo (near Patambuco , 34 km northeast of Sicuani ) (- 14.1225 S, - 70.9517 W), 3773 m a GoogleMaps   .s GoogleMaps   .l., 5 February 2007, Juan C . Chaparro col GoogleMaps   .; paratype female ( MUBI), same data as holotype GoogleMaps   .

Etymology

The specific name is in honour of Roberto Gómez Bolaños (1929–2014), commonly known by his pseudonym ‘Chespirito’. He was a Mexican screenwriter, actor, comedian, film and television director, widely regarded as one of the most important Spanishlanguage humorists of the twentieth century. Curiously, the shape of the spermatheca of female of H. chespiritoi   sp. nov. resembles the small vinyl antennae of ‘Chapulín Colorado’, a comical and bungling superhero created by R.G. Bolaños.

Diagnosis

Males of H. chespiritoi   sp. nov. can be distinguished from those of the other species by the palpal bulb with a slightly curved and very thick embolus and a well-developed basal digitiform apophysis ( Figure 24a–d View Figure 24 ). Females can be distinguished from those of all other species by the shape of the spermathecae with a basal portion much wider than apical; rounded apical median region and apical lateral projections very well developed ( Figure 26e View Figure 26 ).
