Zenoria similaris

Zenoria similaris

HOLOTYPE MALE.—Length 3.48 mm, width 2.95 mm. Form round, elytron slightly narrower and elongate posterior to middle. Color black; broad anterior and lateral margins of pronotum, head and mouthparts, underside of pronotum, legs, and abdomen yellow; discal area of elytra appearing shiny, black, nonpubescent. Pronotum covered with grayish white, semidecumbent pubescence, average length of hairs 0.12 mm; punctures fine, separated by 1 to 3 times their diameter; width to length ratio 2.01:0.91 mm. Elytron covered with dense grayish white, semierect pubescence, discal area with pubescence dark brown, average length of hairs 0.16 mm; coarse punctures deep, separated by their diameter or less, not extending onto discal area, interspersed fine punctures separated by 1 to 2 times their diameter; margin of elytron broadly explanate, strongly sinuate in lateral view; epipleuron with inner carina extending half the distance to outer margin. Postcoxal line extending caudad nearly to hind margin of first abdominal sternum, outer end abruptly curved cephalad. Genitalia with basal lobe longer than paramere, tapering from near base to bluntly rounded apex; paramere short, narrow, gradually curved downward at apex (Figures 48, 49); sipho sinuate before apex, curved down and outward, acuminate (Figure 74).

FEMALE.—Similar to male except a very narrow anterior pronotal margin yellow, underside of pronotum and prosternum black.

VARIATION.—Length 3.43 to 3.51 mm, width 2.91 to 2.98 mm. The basal black area of pronotum covers between two-thirds and three-fourths of pronotal area, apical border may be emarginate with yellow medially. The discal area of the elytra has a narrow band of grayish white pubescence separating the dark discal spot in half on typical specimens, giving the appearance of a small round dark spot on each elytron. On many of the examples in the type series this narrow band is missing, the dark area being one large central spot.
