description: Camisolus ptinoides sp. nov.
Length 3.5–3.8 mm (n=2). Pronotal width 0.9–1.0 mm; elytral length 2.1 mm, elytral width 1.5 mm at broadest point, 1.1 mm at elytral bases. Color uniformly dark brunneus. Dorsum of head with dense, minute punctures bearing slender setae. Antennal segments 1–9 elongate, 10–11 as long as wide. First two antennal segments subequal in length, slightly wider than segments 4–6. Segments 3–6 extremely slender, elongate (> 4x as long as wide). Segment 7 elongate, broader than preceding three segments, approximately equal in length to segment 2; segment 8 elongate, slender, cylindrical, narrower than segments 7 and 9. Segments 9–10 subconical, wider than all segments excluding segment 7; segment 11 ovate, as long as 10, with apex weakly produced. Clypeus broad, transverse but slightly narrowed anteriorly; labrum subquadrate, ~ 2x as long as clypeus, anteriorly rounded, with dense array of minute, trumpet-shaped sensillae on dorsal face. Mandibles (Fig. 2) heavily sclerotized, roughly triangular in dorsal view, tapering in distal half; mandibular apex narrow and weakly bilobed; mesal lobe of mandible membranous, bearing distal cluster of minute setae or slender spines; mola robust, ~0.45 as long as total length of mandible (measured along inner face), transversely ridged, with interior-facing membranous lobe coated with small spines. Maxilla (Fig. 3) with large, robust lacinia (~ 2x as wide as galea); lacinial apex armed with five large, blunt spines distally, comb of smaller spines proximally; interior /dorsal face of lacinia bearing dense array of short trumpet-shaped sensillae. Galea slender, largely membranous, with dense apical brush of setae and minute sclerite at base. Maxillary palpi four-segmented; basalmost palpomere short, triangular; palpomere 2 elongate, distally expanded; palpomere 3 quadrate; apical palpomere weakly expanded (~1.2x as wide as penultimate palpomere), with membranous digitiform sensilla at apex. Labial palpi 3-segmented, terminal palpomere slender (approximately 0.5x width of penultimate palpomere) and slightly elongate (1.5x as long as 2nd palpomere) with membranous apex; interior faces of basal labial palpomeres thickly coated with campaniform or very short digitiform sensillae. Mentum subquadrate, trapezoidal, apex approximately 0.6x as wide as base. Submentum triangular, weakly transverse, separated from mentum by complete impressed groove.
Pronotum with fine, minute punctures across disc, bearing minute setae; posterior region of pronotum with 10– 12 deep, broad submarginal punctures. Hind margin of pronotum with large, complete punctures: four smaller median punctures and two larger lateral punctures extending though pronotal margin to hypomeron. Lateral margins of pronotum with deep, broad dorsal and ventral punctures, nearly contiguous internally. Hind angles and posterior part of pronotal margins produced, pronotal base narrower than elytral bases. Male protarsi with basal segment weakly expanded, first three segments bearing tenent setae; male mesotarsi not expanded and without tenant setae. Male mesotibial apex with large, blunt spine (Fig. 4).
Male terminalia. Male sternum 8 broad, transverse. Male genital segment (Fig. 6) with slender tegmen, short anterior apophysis. Penis (= median lobe) of aedeagus simple, ovate, weakly tapering to blunt, flattened, recurved apex (Fig. 5). Parameres slender at base, broad and expanded apically, paramere apices truncate and bearing dense, interior-facing brush of setae; phallobase reduced to slender, symmetrical membrane, fused to paramere bases and encircling base of penis. Endophallus armed with many minute spines, without larger sclerites or teeth.
Female terminalia. Ovipositor with paired coxites bearing minute styli with multiple long setae. Bursa copulatrix and spermatheca membranous, with no visible sclerotized regions.

Etymology. The genus name Camisolus is a combination of part of the name Camiarus and the English camisole (a ladies’ undergarment), alluding to both a morphological affinity with Camiarus and the punctate, “lacy” appearance of the elytra. The specific epithet ptinoides refers to this species’ superficial resemblance to ptinine anobiids, e.g. Ptinus L.
