Fidia papillata Strother , New Species
( Figs. 16 View FIGURES 13–16 , 41, 65, 73, 104; Map 7)
Holotype ♂ ( MCZC): " MEXICO: Hidalgo 46 km SW Tamazunchale 4900', 4 June 1987 R. Turnbow / RHTC [yellow, handwritten] / Not in MCZ [handwritten] MCZ-B, E.G. Riley, 87 / HOLOTYPE Fidia papillata
M.S.Strother 1993 [red]". The specimen is glued on a point and is in excellent condition with only the right mesotarsus missing. The dissected abdominal sterna and terga are glued on a rectangular card pinned beneath the specimen. The following structures are preserved in glycerin in a microvial pinned beneath the specimen: left antennomeres 8–11, left metatarsomeres 4+5, and ovipositor with genital chamber and spermatheca attached.
Description (of holotype). TL = 6.15 mm, HW = 2.72 mm. Color: Head, pronotal disc, elytra, tibiae, and tarsi orange-brown to red-brown; lateral aspect of pronotum and most of each thoracic sternum black; abdominal sterna pale orange-brown with first four sterna bearing dark brown, transverse semicircular spot on each lateral aspect, spots becoming smaller and less distinct on successive sterna; femora fulvous at base abruptly becoming darker red-brown distad of basal 1/3; pubescence of head and most of elytra straw-yellow, bright golden-yellow on midline of pronotum, blackish on either side of pronotal midline, and pale golden on lateral aspect of pronotum; elytra with relatively broad, feebly defined, transverse blackish band at apical 1/3, proximal to apical declivity. Pronotum: Slightly longer than wide, widest at middle, sides gently convex in dorsal view, equally narrowed anteriorly and posteriorly, dorsum straight in lateral view; densely, coarsely punctatereticulate; pubescence long, recumbent, relatively sparse but forming slightly denser stripe along midline. Mesepisternum: Entirely glabrous. Elytra: Intrahumeral callus well-developed; sutural area between intrahumeral calli impressed; large, deep, subcircular postcallosal impression; second impression posterolaterad the postcallosal impression, mesally bordered by large, rounded, oblong swelling separating more shallowly impressed sutural area; apical 1/3 distinctly declivitous, broadly, shallowly impressed near suture; disc coarsely punctate-striate; asetose punctures large, irregularly shaped; interstices flat to convex, densely rugulose-punctulate; pubescence relatively sparse, generally posteriorly directed, but setae in impressions more or less radiate from center. Abdomen: Medial area of all sterna evenly convex, uniformly densely punctulatepubescent; apical margin of last sternum truncate, bearing two small papillae; pygidium dorsally feebly impressed medially in apical ½; apex of pygidium truncate with distinct posterolateral angles, each angle feebly produced into small, acute tooth. Legs: Pro- and mesofemora swollen, widest at middle, distinctly tapered toward base; hind femora much longer than pro- and mesofemora with basal ½ extremely narrow, widest in apical 1/3. Spermatheca: Modified basal arm type ( Fig. 104 View FIGURES 103–108 ).
Etymology. Feminine form of Latin papillatus, meaning bearing papillae; denoting the two small papillae on the apical margin of the last abdominal sternum of the holotype.
Diagnosis. Large (approximately 6.15 mm.); pronotum coarsely reticulate-punctate, bearing relatively dense, bright golden-yellow pubescent medial longitudinal stripe; each elytron with two distinct impressions posteriad of intrahumeral callus ( Fig. 16 View FIGURES 13–16 ), each bearing radiating setae; metafemur long, basal ½ extremely narrow (Fig. 41); apical margin of last abdominal sternum truncate, bearing two small papillae ( Fig. 65 View FIGURES 61–70 ); apical margin of pygidium truncate with distinct posterolateral angles ( Fig. 73 View FIGURES 71–75 ). Males are unknown.
Fidia papillata is very distinctive and is not likely to be confused with any other species. Fidia xanthonioides is similar to F. papillata in having impressions on the disc of the elytra but is much smaller, lacks goldenyellow setae on the pronotum, has the metafemur narrowed only in the basal 1/2, and females lack papillae on the apical margin of the last abdominal sternum.
Distribution (Map 7). Known only from the holotype.
