Macrotingis novicis Drake, 1928

( Figs 1B , 2B , 3B , 4B and 5B )

Macrotingis biseriata novicis Drake, 1928: 4 ; Drake & Ruhoff, 1965: 294.

Macrotingis novicis: Froeschner, 2003: 29 .

Diagnosis. Head black; rostrum moderately long, reaching the posterior half of mesoesternum; pronotal disc with three carinae; paranota with two rows of areolae with those in the outer row bigger than those in the inner row; thoracic sterna black; mesosternal rostral laminae subparallel; costal area with anterior and posterior thirds with one row of areolae, medial third with two; abdomen bicoloured, pre-genital segments black, genital segments red brown.

.

Redescription. Total body length (females N = 4 and males N = 3, respectively): 5.19–5.33–5.33–5.46 5.59–5.13–5.53. General colour yellow brown. Head black. Cephalic spine slender, erect, covered with dispersed, long, erect setae ( Figs 2B , 3B ). Clypeus black. Bucculae yellow, with three rows of areolae, posteriorly wider. Rostrum yellow except the brown apex, moderately long, reaching up to posterior half of mesoesternum. Antennae 1.2 to 1.3 times the length of the body; segment Ibetween 6.0 and 7.1 times the length of the head, with short, semierect setae; segment II subconic, with short, semierect setae; segment III with scattered long semidecumbent setae; segment IV with abundant long, semidecumbent setae and some scattered short, semierect setae.

Pronotal disc red brown, coarsely pitted, three carinae ( Fig. 4B ). Hood projects forwards to middle of eyes, middle line with long, semierect scattered setae ( Fig. 3B ). Callus dark brown, depressed, with abundant long, semidecumbent setae. Paranota subvertical, margins smooth with long dispersed setae; with two rows of areolae, areolae in outer row bigger than those in inner row. Posterior process yellowish brown. Thoracic sterna black. Rostral laminae: mesosternal laminae subparallel; metasternal laminae as long as space separating both laminae.

.

Hemelytra ( Fig. 5B ): costal area subhorizontal, anterior and posterior thirds with one row of areolae, medial third with two, areolae larger posteriorly. Subcostal area with two rows of areolae, areolae of medium size. Discoidal area at its maximum width with five rows of small areolae.

Abdomen bicoloured, pre-genital segments black, genital segments red brown.

Material examined. 4 ♀ and 3 ♂, Mexico, Chiapas, 5 mi north Nuevo Tenochtitlan , 3000´, 7.viii.1990, J.C. Schaeffer ( NMNH) .

Distribution ( Fig. 7 ). Honduras ( Drake, 1928) and México ( Froeschner, 2003).

Discussion. This species is very similar to M. biseriata , in fact, it was described as a subspecies of this species until Froeschner (2003) raised to the category of species. Macrotingis novicis can be distinguished from species other than M. biseriata by its black thoracic sterna and bicoloured abdomen. It can be distinguished from M. biseriata by its black head, uni-biseriated costal area and short rostrum, which only, reaches the posterior half of the mesosternum, and subparallel mesosternal rostral laminae.
