Type Species: Pilostenaspis lateralis ( LeConte, 1884 ) The following three species are included in Pilostenaspis : P. c op e i sp. nov. , P. lateralis ( LeConte, 1884 ) comb. nov. , and P. pilosella ( Bates, 1892 ) comb. nov. Description. Form small to moderate size, somewhat depressed, oblong; pronotum at sides, and lateral margin of elytra, orange or reddish-orange, dorsum densely, coarsely punctate, clothed with a mixture of long and short erect pale hairs. Head small; front short, deeply impressed transversely, very coarsely, confluently punctate above; mandibles simple, acute at apices; palpi short, apical segment of labial and maxillary pair truncate at apex; genae small, very short, subtruncate at apices; antennal tubercles broad, slightly elevated, apices rounded; eyes moderately large, finely faceted, upper lobes small, well separated; antennae 11 segmented, slender, scape conical, densely, coarsely punctate, reminder of segments densely, finely punctate with a few, short, erect hair beneath, apices of segments 3–11 with depressed to suberect black hair, dorsal and ventral surface densely clothed with short, depressed pubescence, segments 4–11 laterally carinate, 11th vaguely appendiculate. Pronotum broader than long, lateral angle on posterior half obtuse, rather evenly rounded to apical margin; disc very coarsely, confluently punctate, moderately clothed with long, fine, erect hairs; prosternum more finely but rugosely, transversely punctate, pubescence like that of pronotum, intercoxal process narrower than coxae, slightly elevated above procoxae, abruptly declivous behind, cavities wide open behind; mesosternum with intercoxal process subequal to or narrower than coxal cavities, slightly produced below coxae, abruptly, declivous anteriorly, sides densely clothed with erect pale pubescence; metasternum finely punctate, densely clothed with pale, erect pubescence. Scutellum triangular, apex acute. Elytra slightly more than twice longer than broad, very coarsely, densely punctate, punctures only slightly smaller apically, disc moderately clothed with erect pubescence, apices rounded, margin slightly sinuate, sutural angle dentiform. Legs slender, densely punctate, clothed with long, erect, pale hair; hind femora shorter than body; tibiae slender, apically with two short spines; hind tarsi slender, 1st segment about as long as following two segments together, 3rd segment cleft to base. Abdomen finely punctate, clothed with pale, erect pubescence. Male: Antennae longer than body, extending about 3 segments beyond elytra. Female: antennae shorter than body not attaining apices of elytra. Abdomen with 5th sternite broadly rounded (female); broadly, shallowly emarginate (male). Remarks and diagnosis. The genus Pilostenaspis is created to include Pilostenaspis copei sp. nov. , P. lateralis (LeConte) comb. nov. , and P. pilosella (Bates) comb. nov. . The characteristics that distinguishes Pilostenaspis , which do not agree with other genera (i.e, Callistochroma gen. nov. , Crioprosopus Audinet-Serville , Megapurpuricenus gen. nov. , Purpuricenus Dejean or Stenaspis Audinet-Serville ) include: (1) long erect hair covering the entire body (i.e, especially on femora, tibia, and elytra); (2) coarsely and contiguously punctate dorsum (i.e., on the vertex, pronotum and elytra ( Figs. 25 a–25c); (3) densely, deeply punctate femora and tibia; and (4) elytra that are not costate (i.e., vaguely costate on Megapurpuricenus ). These three species (i.e., Pilostenaspis copei , P . lateralis , and P . pilosella ) also have the lateral margins of the pronotum and elytra that are reddish, and an intercoxal process of both pro- and mesosternum that are protuberant or subtuberculiform ( Figs. 26 a–26b). According to a comment made by Bates in his description for Stenaspis pilosella , “ The species is undoubtedly a Stenaspis ,” however, the dense punctures and vestiture will amply distinguish it from Stenaspis . Etymology. The etymology of the name “ Pilostenaspis ” is the Latin prefix pilo- or “hairy”, and genus Stenaspis Audinet-Serville where the species pilosella was originally placed.
