Mucrotettix Perez-Gelabert, Hierro and Otte, 1998

Fig. 13−14

Mucrotettix has two species from the Dominican Republic: Mucrotettix gibbosus Perez-Gelabert, Hierro and Otte, 1998 ( Fig. 13 ) and M. spinifer Perez-Gelabert, Hierro and Otte, 1998 ( Fig. 14 ). Mucrotettix is morphologically similar to Truncotettix , but can be distinguished from it by its sharply pointed posterior margin of pronotum, slightly larger body, 14-segmented antennae, and less tectiform pronotum, with anterior margin not produced over vertex ( Perez-Gelabert et al. 1998; Fig. 13 , 14 ). These two species can be distinguished by the following characteristics: M. gibbosus has a wider scutellum ( Fig. 13D ), rounded lateral lobes of pronotum ( Fig. 13A ), and fore and middle legs without spines or projections ( Fig. 13 A-D), whereas M. spinifer has a narrower scutellum ( Fig. 14C ), truncated lateral lobes of pronotum ( Fig. 14A ) and fore and middle legs with spines or projections ( Fig. 14 A-C) ( Perez-Gelabert et al. 1998).
