Macrotingis uniseriata Champion, 1897: 22 ; Drake & Ruhoff, 1965: 294; Froeschner, 2003: 29.

.

Diagnosis. Head red brown; rostrum moderately long, reaching posterior half of mesosternum; pronotal disc with three carinae; paranota with two rows of areolae with those in the outer row bigger than those in the inner row; sterna on prothorax and metathorax reddish brown and mesothorax black; mesosternal rostral laminae converge gradually posteriorly; costal area with one row of areolae; abdomen unicoloured red brown.

Redescription. Total body length 5.13. General colour yellow brown. Head reddish brown. Cephalic spine slen- der, erect, glabrus ( Figs 2D , 3D ). Clypeus dark brown. Bucculae yellow, with three rows of areolae, similar width over all its length. Rostrum yellow except the black apex, moderately long, reaching posterior half of mesoesternum. Antennae 1.2 times the length of the body; segment I 4.5 times the length of the head, with short, semierect setae; segment II subconical, glabrus; segment III with abundant long semierect setae; segment IV with abundant long, semidecumbent setae and some scattered short, semierect setae.

Pronotal disc dark brown, coarsely pitted, three carinae ( Fig. 4D ). Hood projecting as far as the middle of eyes, glabrus ( Fig. 3D ). Callus dark brown, depressed, with abundant long, semidecumbent setae. Paranota subvertical, margins serrated, glabrus; with two rows of areolae with those of the outer row bigger than those of the inner row. Posterior process yellowish brown. Pro and metasternum brown, mesosternum black. Rostral laminae: mesosternal laminae converge gradually posteriorly; metasternal laminae longer than space separating the laminae.

.

Hemelytra ( Fig. 5D ): costal area subhorizontal, with one row of areolae, towards the middle of this area there may be some extra areolae, areolae increase in size posteriorly. Subcostal area with three rows of areolae, areolae small. Discoidal area at its maximum width with three rows of small areolae.

Abdomen unicoloured red brown.

Type material examined. Paralectotype: 1 ♂, Guatemala, Capetillo , B.C.A, Rhyn. II. Champion ( BMNH) .

Distribution ( Fig. 7 ). Guatemala ( Champion, 1897).

Discussion. Macrotingis uniseriata , like M. novicis and M. biseriata , has a pronotum with three carinae and biseriate paranota, and has the same rostral length and unicoloured abdomen as M. schaffneri . It can be distinguished from the other members of the genus by its uniseriated costal area and red brown pro and metasternum and black mesosternum.
