Hormetica luteomarginata, a new Blattid (Orthoptera) from Brazil
Zoologische Mededelingen , Volume 30 - Issue 9 p. 111- 114
While studying the small but interesting collection of Blattidae, submitted to me for study by Mr. C. Willemse of Eygelshoven (L.), I found a new Blattid for which I propose the name Hormetica luteomarginata nov. spec. The new species is represented in the Willemse collection by two male specimens. It belongs to the forms having the tegmina marked with black and the tegmina and wings extending beyond the apex of the abdomen. The most striking features are the fully developed tegmina and wings, the black band extending along the anal sulcus and the yellowly bordered black abdomen. Type ♂; Esperito Santo, Brazil (Willemse collection). Size medium for the genus, form moderately depressed, elliptical (fig. 1). Head in dorsal aspect not visible cephalad of pronotum, in cephalic aspect broad cordiform, greatest width across eyes nearly equal to greatest depth (as 12 to 13), face flattened, with scattered punctulae; the area between the eyes is slightly depressed; occipital interspace between eyes broad, half the entire width of head and equal to eleven-twelfth of that between the internal margins of antennal scrobes; ocellar spots mesad of eyes, with a faint transverse impression between them; maxillary palpi with ultimate article longer than penultimate and shorter than antepenultimate, the proportions Fig. i. Hormetica luteomarginata nov. spec, dorsal view of male. X 3. being as 20, 17 and 23 respectively; the penultimate being infundibuliform. Pronotum hormeticoid, lateral and cephalic margins of pronotum continuously arcuate; the general arcuation of latero-cephalic margin as seen from dorsum evenly converging to the supra-cephalic cucullation; the caudo-
