Figures 10 View FIGURES 6 – 10 , 15 View FIGURES 11 – 15 , 20 View FIGURES 16 – 20
Holotype (male): MEXICO, VERACRUZ "Los Tuxtlas"
Diagnosis. Similar to T. orientalis Zaragoza ; however T. granulatus may be distinguished by its granulate, non-gibbous head and labrum with a distinct median prominence. The recorded distribution for these species is also different, with T. orientalis known from Tamaulipas and Chihuahua and T. granulatus from Veracruz.
Description. Size. Length 5.78; width 1.16. Color. Dark brown. Head. Flat ( Fig. 10 View FIGURES 6 – 10 ), at eye level nearly as long (1.00) as wide (0.92), slightly wider than pronotum (0.82). Interocular area flat; distance between pronotum and eyes 2.08 times length of eye. Integument shiny, rugose, coarsely granulate and umbilicate, each point with a long, imbricate seta. Antenniferous tubercles prominent. Interantennal area excavate, twice as wide as length of scape. Antennae as long (1.62) as apical palpomeres (1.60). Eyes small, slightly prominent, longer (0.24) than wide (0.12); interocular distance wide, 5.5 times width of eye. Frons subvertical, anterior margin straight. Labrum with prominent median lobe. Thorax. Pronotum ( Fig. 10 View FIGURES 6 – 10 ) wider (0.82) than long (0.72), anterior margin straight, posterior margin concave, sides nearly straight; disc convex, shiny, integument chagrined with sparse, tiny punctures, each with a yellow seta. Scutellum shiny, sparsely thick dotted, setose; posterior margin slightly emarginate. Elytra ( Fig. 15 View FIGURES 11 – 15 ) 6.44 times as long as wide, subparallel; posterior margin rounded; integument chagrined in anterior half, rough and coarsely punctate in posterior half, each puncture with a yellow seta. Membranous wing slightly more than twice as long as wide ( Fig. 20 View FIGURES 16 – 20 ). Abdomen. Integument shiny, minutely punctate and pilose. Female unknown.
Distribution. VERACRUZ, Biological Station "Los Tuxtlas".
Type material. Holotype male: MEXICO, VERACRUZ, Est. de Biol. Los Tuxtlas; Alt. 280 msnm. T. M. "El Vigía" 13 abril 1986, Col. E. Ramírez (COL-TIP-1493).
Etymology. The name refers to the granulate head of the holotype.
Analysis of qualitative and morphometric characters ( Table 1 View TABLE 1 , 2) allows distinction of the species of the genus Telegeusis . Elytral length defines two groups, the first containing T. debilis , T. orientalis , and T. granulatus sp. n., which have the elytra 5-6 times as long as wide, and the second containing T. schwarzi , where the length and width of the elytra is almost equal. In the other species the length of the elytra is variable.
