urn:lsid:zoobank.org:act:0CD2397D-D69F-44AA-8C0C-D0BC6877FBC9 ( Figs. 4 View Figure 4 , 5 View Figure 5 A-5E)
Description. Adult male. Forewing length 1.69–1.98 mm (mean = 1.83 mm, SD = 0.09, n = 24). General color, in ethanol, brown ( Fig. 4 View Figure 4 ). Antennae 18-articulated; scape enlarged, semielliptical, with posterior margin produced in anterior view ( Fig. 5E View Figure 5 ); pedicel slightly globose, chalice-like, about the same length as that of the length of the next two articles combined ( Fig. 5E View Figure 5 ); flagellomeres short, covered by scale-like setae, apical article tapering ( Fig. 5E View Figure 5 ). Ocelli 2. Maxillary palpi 5-articulated, 4th palpomere oval, 5th palpomere thin and as long as 4th. Labial palpi 3-articulated. Mesoscutellum with transverse suture. Metascutellum diamond-shaped. Tibial spurs formula 0,2,4, each pair of meso- and metatibial spurs with one spur about twice as long as the other. Fore- and hind wings with long dark brown setae, forewings with white setae forming spots ( Fig. 4 View Figure 4 ). Abdominal segment VII with ventromesal process, bifurcate in lateral view, with dorsal branch longer than ventral ( Fig. 5C View Figure 5 ).
Male genitalia. Segment VIII with a pair of dorsolateral processes, directed anterad, with apex curved posterad, each one bearing an elongate, spine-like seta, extending beyond segment apex ( Figs. 5A, 5C View Figure 5 ); in lateral view, with bifid apex, dorsal portion rounded, ventral portion acute ( Fig. 5C View Figure 5 ); in ventral view, posterior margin with a deep mesal Y-shaped incision, laterally to mesal incision paired lobes with a digitate process internally, and outerad of lobes paired narrow U-shaped incisions ( Fig. 5B View Figure 5 ). Segment IX fused with segment X, reduced ventrally; with a pair of slender, lateral elongate processes, slightly curved inwardly in dorsal view ( Fig. 5A View Figure 5 ); anterolateral margins with a pair of slender apodemes reaching segment VI internally ( Figs. 5 View Figure 5 A-5C). Segment X long, membranous, slightly elliptical in dorsal view ( Fig. 5A View Figure 5 ); dorsally with a pair of sclerites shaped like a leg on tiptoe, with a constriction followed by a subbasal dilatation, tapering to an acute basis, apex rounded ( Fig.5A View Figure 5 ). Subgenital plate, in ventral view long, reaching segment VII internally; anterior portion projecting into a pair of rectangular rods; posterior margin rounded, with a wide subapical open area ( Fig. 5B View Figure 5 ). Inferior appendages absent. Phallus tubular, long, mesolaterally with four digitate sclerites grouped at each side of phallus, at midlength, sclerites partially overlapping ( Fig.5D View Figure 5 ); with a pair of apical lobes, each tapering to a rounded apex, directed inwardly, with internal margins sclerotized ( Fig. 5D View Figure 5 ); ejaculatory duct projecting between apical lobes ( Fig. 5D View Figure 5 ).
Taxonomic notes. Alisotrichia calori sp. nov. belongs to theorophila group because of the presence of dorsolateral processes on segment VIII ( Fig. 5A View Figure 5 ). This new species is very distinctive, but in some respects resembles the previous one, A. froehlichi sp. nov., andA. dilatata sp. nov., mainly because of the deep Y-shaped and the lateral pair of incisions on posterior margin of segment VIII in ventral view ( Fig. 5B View Figure 5 ). Alisotrichia calori sp. nov. can be easily distinguished from these by: (1) the shape of the dorsal sclerite on segment X, which resembles a leg on tiptoe; (2) the mesal Y-shaped incision on posterior margin of segment VIII in ventral view, delimited by paired lateral rounded lobes, each with a very small digitate process internally ( Fig. 5B View Figure 5 ); and (3) the shape of the phallus, with lateral digitate sclerites grouped laterally at midlength ( Fig. 5D View Figure 5 ).
Etymology: This species is named in honor of Dr. Adolfo Calor, Brazilian entomologist and former student of Dr. Claudio Froehlich, in recognition of his contributions to the study of the neotropical caddisflies and for providing material used in this work.
Distribution: Brazil (Bahia, Paraíba).Caatinga and Atlantic Forest biomes.
