Hadronemidea esau Reuter Figures 3, 37, 39–41

Hadronemidea esau Reuter, 1908: 173 [n. sp.]; Carvalho, 1958: 69 [catalog]; Schuh, 1995: 116 [catalog].

DIAGNOSIS: Recognized by the weakly arcuate and strongly marginate lateral margins of the pronotum (figs. 3, 37A); the transverse posterior protuberance near posterior margin of pronotum not strongly elevated; the strongly curved mesotibia in males, covered with scattered bristlelike setae (fig. 37F); the expanded and extensively denticulate rami of the left spicule (fig. 39, arrow); and the roundly expanded and denticulate apex of the right spicule (fig. 39, arrow).

Hadronemidea esau may be distinguished from H. echinata by the key provided and by the diagnostic characters mentioned above.

REDESCRIPTION: Male: Large, robust, total length 5.35–5.56. COLORATION (fig. 3): HEAD: Mandibular plates dark brown, sometimes black; maxillary plates black, anteriorly shiny; labrum dull. THORAX: Anterior lobe of pronotum black, posterior lobe, including lateral carina, orange-red, anterior margin with a U-shaped black macula. STRUCTURE: HEAD: Labrum long, as long as first labial segment, densely setose, broad and weakly rounded apically (fig. 37A); antennal segment III with short sparse setae on apical third. THORAX: Pronotum with lateral margins strongly carinate (fig. 37A); transverse posterior protuberance of pronotum low. Legs: Mesofemur with setae shorter than femur width (fig. 37F); mesotibia strongly curved inward, setae short, sparse (fig. 37F). GENITALIA: Genital capsule subtriangular, not rounded, aperture medium-sized, anterior margin not well sclerotized (figs. 37E, 39); left paramere strongly curved, sickle-shaped, ventral process blunt (fig. 39, arrows); right paramere weakly rounded apically, almost truncate, ventral margin produced cephalad (fig. 39, arrow); rami of left spicule unequal in length, apical spicule shorter than preapical, both enlarged distally, strongly denticulate (fig. 39, arrow); right spicule apically flattened and expanded, margin denticulate, directed upward (fig. 39, arrow).

Female: Similar to male in structure and coloration, but larger, total length 5.21–6.34. STRUCTURE: GENITALIA (fig. 40): Subgenital plate apically rounded; dorsal lobes of interramal sclerites with distal half lateral margin gently curved inward; sclerotized rings ovate, not produced posteriorly; accessory sclerite on anterolateral margin acute.

DISTRIBUTION: Known from central Mexico and the Sierra Madre Oriental (fig. 41).

HOSTS: Available host-plant data for H. esau indicate that the taxon is restricted to legumes. Half the records are on Dalea sp. and half on unidentified species of Fabaceae .

DISCUSSION: Reuter described H. esau based on two females from Mexico. Only one specimen bearing an identification label in Reuter’s handwriting from the Helsinki collection was found. Reuter specimens were from two localities, ‘‘Takubaya’’ and ‘‘Chapultepek’’. The examined specimen matches Reuter (1908) description, although the label only states ‘‘ Mexico, Bilimek’’, without a more precise locality, and Bilimek being the collector (cf. Reuter, 1908). It is probable that exact localities were communicated to Reuter by Bilimek himself. Because this specimen is the only one bearing a Reuter determination label that matches his description, except for the specific locality data, I am designating it as the lectotype.

Because Reuter’s description was based on females, the middle leg character of the male was unavailable. The description of the laterally produced pronotum, with a large median black macula, and the length of the antennae are particularly important characters to identify this taxon.
