Hesus mexicanus KORMILEV 1968 ( Fig. 6, 17, 18 View Fig , 24, 29 View Fig ; photo 8))

This species is closely related to H. subarmatus , sharing the tuberculate lateral margins of anterior pronotal lobe. They can be separated by the characters given in the key. Single females cannot clearly be assigned due to variability in colouration and pronotal surface sculpturing. Colouration generally brown, the posterior half of deltg III-VI are ochraceous as is mostly the anterior half of tergite VII, two rings on tibiae (the apical one sometimes fading on fore leg), an elongate spot on membrane posterior to apex of corium. The base of antennal segment I and segments II-IV frequently are of lighter colour (photo 8). Venter medially ochraceous, lateral margins, sternites II and VII, pro-, meso-, and metasternum brown. Spiracles II-V ventral, VI sublateral but not visible from above, VII dorsolateral, VIII terminal. Terminal segments: fig. 17, 18.

Pygophore dorsally rather flat with a narrow, tongue-like medially split sclerite (fig. 29); parameres slender as fig. 24.

M e a s u r e m e n t s:Length33 8.2-8.4mm, ♀♀ 9.7-9.8mm; ratio length of antennae / width of head 2.5-2.8; ratio antennal segment I / segment II 1.54-1.58; head shorter, ratio length / width 1.35-1.41.
