description: <i>Fidia chapini</i> Strother, New Species (Figs. 3, 108; Map 9) <b>Holotype</b> (♀) (TAMU): " MEXICO: Guerrero 3 km S Xalitla, 610m N 18°00'; W 98°24' vii-1-1992; C. Bellamy / HOLOTYPE <i>Fidia chapini</i> M.S.Strother 1993 [red]". The specimen is glued on a point and is in excellent condition with all appendages intact. The dissected abdominal sterna, terga and pygidium are glued on a rectangular card pinned beneath the specimen. The ovipositor, genital tract, and spermatheca are preserved in glycerin in a microvial pinned beneath the specimen. <b>Description (of holotype).</b> TL = 6.85 mm, HW = 3.61 mm. <b>Color:</b> Head glossy black with faint bluegreen luster, gena dark red-brown; pronotum glossy black with faint blue-green luster; elytra very dark redbrown verging on blackish basally, with blue-green luster more pronounced basally and laterally; thoracic sterna dark red-brown to nearly black on metasternum; abdominal sterna black with blue- to brassy-green metallic luster, pygidium dark red-brown; femora and tibiae dark red-brown, tarsi light red-brown; pubescence white. <b>Pronotum:</b> Slightly wider than long, widest at middle, slightly narrower anteriorly than posteriorly, sides evenly, distinctly arcuate in dorsal view, dorsum distinctly convex in lateral view, with an overall globose appearance; densely, coarsely punctate-reticulate, punctures relatively large; interpunctal surface nitid; pubescence relatively sparse, erect on disc, suberect on lateral aspects, not obscuring surface sculpture. <b>Mesepisternum:</b> Entirely glabrous. <b>Elytra:</b> Intrahumeral callus obsolete; apex of humeral callus impunctate, glabrous; asetose punctate-striae entirely obsolete, surface densely, coarsely punctate-reticulate, some punctures on lateral aspect, posteriad humeral callus, contiguous, giving surface feebly reticulate-undose (with undulating, broadish, nearly parallel depressions running more or less into each other; wavy) to reticulate-rugose appearance; pubescence moderately dense, suberect, not obscuring surface sculpture. <b>Abdomen:</b> Medial area of first four sterna evenly convex, uniformly punctate-pubescent; last sternum declivitous in lateral view, apical margin subtruncate, lacking medial process; pygidium dorsally flat in apical ½ with subacutely rounded apex. <b>Legs:</b> Femora gradually tapered towards base; spinose apical border of metatibia obtusely rounded. <b>Penis:</b> Males unknown. <b>Spermatheca:</b> Basal swelling type: proximal part not noticeably swollen, upper and lower surfaces subparallel, not constricted immediately proximad distal part, base with narrow constriction separating globular basal swelling; distal part subangulately recurved, gently tapered to small, acute, upturned apical appendix; spermathecal duct and spermathecal gland emanating from apex of basal swelling. <b>Etymology.</b> Named in honor of Joan B. Chapin for her indispensable guidance and assistance during this revision. <b>Diagnosis.</b> Large (approximately 6.85 mm); form robust in dorsal view (Fig. 3); pronotum noticeably wider than long; elytra coarsely punctate-reticulate; dorsum very dark red-brown to blackish with faint bluegreen luster; basal swelling type spermatheca (Fig. 108). <i>Fidia chapini</i> is very distinctive and is not likely to be confused with any other species. <b>Distribution (Map 9).</b> Known only from the holotype. <b>Natural History.</b> Unknown.
