( Figs. 1­18 ) Type material . Holotype :, BELIZE : Orange Walk Distr., Rio Bravo Conservation / Management Area, La Milpa Station, Chiche Trail, 17º50'22"N 89º01'12"W , lot #119, berlese (C.E.Carlton & D.Murray), 18.v.1997 ( KSEM ). Paratypes : BELIZE :, 2, same data as the holotype ( LSAC ). Diagnosis . Mayatyphlus carltoni is the only known species of the genus Mayatyphlus . If any additional species of Mayatyphlus are ever discovered, M. carltoni could be distinguished by the shape of the aedeagus, especially the apex of the median lobe ( Figs. 13­15 ), and by the shape of the female accessory sclerites ( Fig. 17 ). Description. Length 0.7­0.8 mm . Head with short setae arranged as in Figs. 1­2 . Second and third antennal articles as long as wide and twice as wide as article 3, articles 3­9 strongly transverse, 1.6­2.0 times as wide as long, article 10 1.5 times as wide as long, last article as long as wide ( Fig. 9 ). FIGURES 13­18. Details of Mayatyphlus carltoni Gusarov , gen. n. , sp. n. (paratypes). 13 – aedeagus, parameral view; 14­15 – aedeagus, lateral view; 16 – male sternum 8; 17 – female abdominal segments 9­10, ventral view; 18 – female sternum 8. Scale bar 0.1 mm. Pronotum with short setae arranged as in Fig. 1 , narrowed posteriad, 1.1 times as long as wide, as wide as head and elytra ( Fig. 1 ). Elytra with short setae, with parallel lateral sides ( Fig. 1 ), 1.1 times as long as wide (length measured from humeral level). Abdominal terga with long setae ( Fig. 1 ). Male protarsus with adhesive setae ( Fig. 10 ). Male mesotrochanter with denticle ( Fig. 11 ). Male abdominal sternum 8 with broad apical emargination and narrow medial zone devoid of setae ( Fig. 16 ). Aedeagus with short and narrow parameres, apex of median lobe in lateral view Sshaped, in parameral view asymmetrical, with two subapical processes pointed to the left ( Figs. 13­15 ). Female abdominal sternum 8 as in Fig. 18 . Female accessory sclerites as in Fig. 17 . Distribution. Known from a single locality in Belize . Natural History. Mayatyphlus carltoni presumably inhabits soil and/or leaf litter, and was collected using Berlese funnels.
