Cephalidiosus guilberti, Lis, 2009

Cephalidiosus guilberti sp. nov. ( Figs. 1 –2 View FIGSURES 1–2 )

Diagnosis: The new species is similar to C. sineoroe Guilb. in having four short cephalic spines and narrow paranota; however, C. guilberti has a short dorsomedial cephalic tubercle (it is absent in C. sineoroe ), and its paranota are composed of one row of areolae opposite calli and around posterolateral angles of pronotum (paranota in C. sineoroe are almost lacking, reduced to slight ridges). Moreover, the new species can easily be separated from C. sineoroe by its well developed pronotal carinae (the laterals are carinate, the median is composed of one row of areolae); whereas they all are indistinct in C. sineoroe .

Description (based on a single male specimen): General body colour ochreous with dark brown V-shaped mark on pronotum. Head dark brown, smooth, distinctly convex between eyes; head armed with four (frontals and occipitals) relatively short, yellowish brown cephalic spines and dark brown, short dorsomedial tubercle. Eyes black, small, frons about 4 times wider than the eye width. Bucculae high, composed of four rows of areolae, dark brown with yellow edges; labium reaching the middle of metasternum; labial sulcus slightly enlarged at metasternum ( Fig. 2 View FIGSURES 1–2 ). Antennae slender, segments 1-2 yellowish, third segment gradually darkening from base to apex, fourth segment dark brown. Paranota very narrow, carinate, but slightly wider opposite calli and around posterolateral angles (where they have a single row of areolae). Collar light yellow, composed of four rows of areolae, collar slightly elevated in the middle, forming a small hood. Pronotal disc convex, punctate, triangular pronotal process areolated. Lateral pronotal carinae low, but distinct; median carina relatively high, composed of one row of areolae, its edge in the middle thickened. Pleurites dark brown to black. Hemelytra elongate (more than twice as long as abdomen), abruptly widened at base, their margins slightly curved downward; most veinlets ochreous, a few brownish. Costal area broad, composed of six rows of areolae in its broadest part, areolae large; subcostal area composed of three rows of areolae across the broadest part; discoidal area composed of four rows of areolae in its broadest part (areolae of subcostal and discoidal areas much smaller than those of costal area). Legs yellowish, tarsi yellowish brown; abdominal sterna yellowish, pygophore light brown.

Measurements (in mm): Total body length 3.30; maximum body width 2.13; pronotal length 0.90; pronotal width 0.75; length of hemelytron 2.50; length of antennal segments 0.60:0.12:1.10:0.46.
