Hadronema mexicanum View in CoL , sp. nov. Figures 2, 27, 28, 30, 33

Hadronema militaris: Distant, 1883: 259 [misidentification?, distribution]; Reuter, 1908 [misidentification?, distribution].

Hadronema breviata: Carvalho and Afonso, 1977: 9 [misidentification, distribution].

DIAGNOSIS: Recognized by the curved fuscous marking on the anterior portion of the posterior lobe of the pronotum (fig. 2); the ventral spicule apically decurved in lateral view (fig. 27, arrows); and the slender subequal rami that reach the dorsal spicule.

Hadronema mexicanum is mostly similar to H. pictum due to the bright red posterior lobe of the pronotum but separated from it by the apically decurved left spicule and the greater ratio of antennal segments II/III (table 1). Pale specimens of H. mexicanum may be confused with H. simplex but are easily separated from it by the normally developed evaporatory area on the metepisternum, which is reduced in H. simplex , and by the long subequal rami, which are unequal in H. simplex (fig. 26).

DESCRIPTION: Male: Medium size, total length 3.19–3.55. COLORATION: Black, with red and white markings (fig. 2). HEAD: Black; clypeus with two lateral and one basal irregular longitudinal areas of shiny black spots; frons with two lateral areas of oblique lines composed of irregular shiny black spots; vertex with two small reddish black areas next to eyes; mandibular and maxillary plates reddish black toward apex, mandibular plate brighter; black line connecting bases of mandibular and maxillary plates with antennal socket and eye; labrum shiny black; labium black, segments III–IV shiny black; antennae black. THORAX: Collar and anterior lobe of pronotum black; calli black with irregular shiny areas; posterior lobe of pronotum red, anterior half usually diffusely suffused with black; mesoscutum black, laterally reddish; scutellum black, reddish black on disc; proepisternum black; proepimeron anteriorly black, posteriorly orange red; mesepisternum and mesepimeron reddish black; mesothoracic spiracle black; metepisternum black; venter black. Hemelytra: Clavus black; corium mostly black, costal margin white; cuneus white, medial margin black; area between corium and membrane shiny black; membrane fuscous, veins black. Legs: Black, basal portion of trochanters weakly pale. ABDOMEN: Black, posterior margin of sternites weakly pale. GENITALIA: Genital capsule black; proctiger pale orange, apically brownish; parameres brown. STRUCTURE: THORAX: Metepister- num with evaporatory area rounded on dorsal margin and peritreme large. Legs: Profemur with basal tubercle bifid but with external process small. GENITALIA: Genital capsule subtriangular, without sensory lobe on left side, lateroventral projection on right side of medium size, blunt (fig. 28); insertion of parameres lateral; left paramere sickleshaped (fig. 28); right paramere acute and pointed at apex (fig. 28); ventral spicule denticulate apically and gently decurved apically (fig. 27, arrows), rami subequal, thin, usually not denticulate apically, reaching and surpassing the dorsal spicule (fig. 27); dorsal spicule about a third as long as ventral one, denticulate on apical half (fig. 27).

Female: Similar to male, but larger and broader, vaguely oval (fig. 2), total length 3.61–4.14. STRUCTURE: GENITALIA: Subgenital plate triangular, acute but rounded apically, reaching middle of sternum VIII (fig. 30); dorsal lobes of interramal sclerites narrow, not long, heavily set with microtrichia apically (fig. 30); central sclerotized area on anterior wall well sclerotized, round- ed, transversely divided, ventral sclerite with large process, denticulate, dorsal sclerite with small and medium-sized denticles (fig. 33); sclerotized rings as in figure 30; accessory sclerite of sclerotized rings very small (fig. 30).

DISTRIBUTION: Most known specimens from Central Mexico, in particular from the Sierra Madre Occidental and the Transverse Volcanic Axis, with a few localities in the Sierra Madre Oriental (fig. 35).

HOSTS: Few records of host plants exist for this new species. Two specimens were found on Mimosa (Fabaceae) . Four specimens were found on an unidentified Asteraceae species.

ETYMOLOGY: The name refers to Mexico, the country of origin of all specimens examined.

DISCUSSION: Distant’s (1883) record of H. militare from Mexico is quite probably a misidentification. The species depicted in his fig. 23 of plate 22 may be H. mexicanum , in particular due to the gently posteriorly curved dark spot over the posterior lobe of the pronotum. It is not clear if Reuter’s (1908) mention of H. militare from Mexico really corresponded to this species, because I have not examined specimens of this species

from Mexico. Reuter’s specimens may also correspond to H. mexicanum . Specimens mentioned by Carvalho and Afonso (1977) as H. breviatum were studied, and they correspond to H. mexicanum , not H. breviatum .

Despite some intraspecific variation on spicule morphology, even from the same locality (fig. 27), I consider all the specimens examined as one species. All of them share the peculiarly decurved apex of the vesica, which is not present in any of the other species of Hadronema , and have a similar color pattern.
