HERAEUS ITZELAE View in CoL SP. NOV.

( FIGS 3 View Figure 3 D, 5D, 6M–P, 7)

Diagnosis

Antenna with a pale band on distiflagellomere, pronotum with long, erect setae on anterior lobe, and hemelytra with only short recumbent setae.

Heraeus itzelae sp. nov. and H. setosus sp. nov. have long erect setae on pronotum and scutellum. The distiflagellomere of H. itzelae sp. nov. has a pale band, and the hemelytra have only short recumbent setae; the distiflagellomere of H. setosus sp. nov. lacks a pale band and the hemelytra possess erect setae similar to those on the pronotum and scutellum.

Description

Total length 7.03 ( Fig. 3 View Figure 3 D).

Head: Strongly convex dorsally, orange brown, shiny, smooth, with long erect and short recumbent setae. Head length 1.03, width 0.96. Postocular length 0.38. Eyes slightly protruding, not surpassing the dorsal margin of head in lateral view. Ocelli posterior to an imaginary line passing the posterior border of eyes. Interocular width 0.51, interocellar width 0.30. Labium pale brown with short erect setae, extending to mesocoxae. Labial segment lengths: I 0.98, II 1.04, III 0.88, and IV 0.40. Antennal tubercles slightly divergent. Antenna pale brown, except for darker scapus, with abundant semi-erect and sparse erect setae; distiflagellomere with a wide pale band. Antennal lengths: scape 0.67, pedicel 1.33, basiflagellomere 1.04, and distiflagellomere 1.28. Length of pale band on distiflagellomere 0.53.

Thorax: Pronotum pruinose, brown, punctate, posterior lobe with more abundant and larger punctures, and sparse short, recumbent setae; anterior lobe with long erect setae. Collar length 0.13, anteri- or lobe length 0.75, posterior lobe length 0.58; anterior lobe width 1.07, posterior lobe width 1.70. Pleurae dark brown. Evaporative area short. Scutellum brown, pruinose, punctate with long erect and short recumbent setae. Hemelytra pruinose, with short recumbent setae. Colour uniformly pale brown, costal margin on proximal three-quarters, small inner corial spot, and a small subapical spot hardly paler; membrane greyish brown, veins concolorous. Legs: Coxae brown, shiny, remainder of legs pale brown except protrochanter, meso- and metafemur darker distally, tibiae darker apically ( Fig. 5 View Figure 5 D), setose, with short semi-erect setae, longest on profemur. Profemur with two rows of small spines on ventral surface, one spine larger. Protibia with small tubercles bearing spiniform setae on inner surface.

Abdomen: Brown with abundant, short, recumbent setae. Male genitalia: Pygophore ( Fig. 6 View Figure 6 M, N) rounded, anterior margin of dorsal aperture rounded, inner projections quadrangular. Parameres: Figure 6 View Figure 6 (O, P). Aedeagus: Conjunctiva not spined, vesica with a few minute spines laterally and on sclerotized lobes; processus gonopori long and slender.

Variability observed in paratypes

Similar to holotype in all aspects. Hemelytra varying from almost uniformly pigmented to having a welldifferentiated pattern.

Distribution

Mexico ( Fig. 7 View Figure 7 ).

Etymology

This species is named after our friend and colleague Sara Itzel Montemayor (Museo de La Plata).
