Marcuzzi, G.: New taxa of Neotropical Tenebrionidae (Coleoptera)
Though belonging to Eurymetopi ni (CASEY 1907) the new genus does not fit in any of the genera admitted by CASEY, perhaps the most closely related being Melanastus. The systematics of this tribe seems quite unsatisfactory when we consider that Chilometopon has been attributed by HORN to Epitragini and that Auchmobius appears to necessitate a tribe of its own, perhaps combining some of the characteristics of Trimytini and Eurymetopini* I wish only to call attention to a genus endemic to the northern shores of South America, Paraguania, which I attributed to Trimytini. The new genus which I attribute to Eurymetopini, would perhaps be another example of the very old origin os some Caribbean elements, coming from California, possibly through Mexico. Garridoa gen. n. Belonging to Trimytini sensu CASEY 1907. Outer ridge of mandibles (especially of the left one) very broad, not definitely dentiform at base; body rather short, glabrous, convex, wingless. Metasternum as long as first urosternum. Pronotum widest at about middle, but base slightly wider than apex. Eyes moderately large and not prominent, about half divided by canthus of frontal margin, very coarsely faceted. Garridoa kaszabi sp. n. (Figs 3-4) 4.5-6 mm long, a little elongate, convex, black with exception of antennae, palpi and legs, brownish-ferrugineous. Pronotum well separated from elytra, because of hind angles almost rectangular, base narrower than that of elytra, latter slightly prominent at humeri. Legs and antennae normally developed. — H e a d transverse, rather flat, clypeus and genae distinctly divided to form a very characteristic trilobé structure (Fig. 4). Clypeus greatly prolonged, clasped by external ridge of mandibles, upper surface shining, sparsely and minutely punctured, punctation stronger only on genae. — A n t e n n a e elongate and filiform, with 2-8th articles very similar, somewhat bead-like, last three articles gradually wider, covered with a golden recumbent pubescence, last article definitely shorter than tenth and can be considered as a characteristics of the new genus. — P r o n o t u m transverse, widest at about middle, base only scarcely wider than apex, sides not regularly rounded narrowed regularly towards anterior angles, sligthtly sinuate before hind angles so that anterior angles prominent, quite obtuse, hind angles less prominent, almost rectangular. Upper surface punctured like head. Base slightly sinuate at sides, well pronounced in middle, apex slightly emarginate, base margined only at sides, margin interrupted both towards hind angles and middle one. Before base a shallow depression visible in middle. —E 1 y t r a well separated from pronotum, ovoidal, convex, gradually narrowing towards apex. Base slightly wider than that of pronotum but humeri rounded and prominent. Surface shining, striato-punctate, striae much convex; punctures much stronger in outer striae. Interstriae shining, smooth, furnished only with an extremely fine punctation in anterior and inner part of the surface. Scutellum very reduced, triangular, in this respect differing from CASEY'S description which says "the scutellum well developed". — M e n t u m large, very transverse, subtrapezoidal with apex very gently rounded instead of perfectly straight, rather densely and strongly punctured though a little shining. —Prosternum rather regularly raised towards middle, densely punctured, at sides punctation tending to rugosity (strigose ?), in middle of normal, circular, type. Punctures always well-separated. Intercoxal process very high, rather wide, posteriorly brusquely cut. Surface of prosternum not very shining, coxae very large, somewhat crescent-shaped. Mesosternum very long, practically as long as metasternum, towards apex depressed, towards metasternum raised; shining, furnished with a very sparse but strong punctation, especially in anterior part. Coxae similar to prosternai ones but narrower and longer. Metasternum practically as long as first urosternum, very shining, furnished with a sparse and strong punctation, very much the same as that of the mssosternum, but hind part almost smooth. Intercoxal process a little rounded at tip, not very prominent; coxae very long, anteriorly delimited by a distinctly long groove (present in all the three genera admitted by CASEY, p. 366-367). First urosternum similar to metasternum, with same punctation absent towards hind margin, intercoxal process similar to that of metasternum but a little larger. — E p i p 1 e u r a e very wide at the base, then regularly narrowed towards apex where scarcely recognizable. Surface shining, with a punctations similar to that of meso-and metasternum. Ventral surface of femurs very shining, furnished with a sparse punctation, closer only on hind ones. * CASEY speaks of the "intimate relationships of the Trimytini and Eurymetopini".
