Cis fiuzai Almeida & Lopes­Andrade , sp. nov. ( Figs. 1–5 )

Holotype. Male, BRASIL: MG: Araponga, próx. Vale da Lua, Pico do Boné, 24.ii. 2003, P. S. Fiuza Ferreira & C. Lopes­Andrade. In addition to the locality label, the holotype has a red label with its identification.

Diagnosis. This species can be distinguished from the other described Brazilian species of Cis , but C. leoi , by the following combination of characteristics: (i) distinct seriate and dual elytral punctation; (ii) lack of conspicuous frontoclypeal tubercles in both genders. It can be easily distinguished from C. leoi and C. gumiercostai sp. nov., and also from the other species of the comptus group, by the morphology of the male genitalia.

Description. Male. Body length (excluding head): 1.45–1.60 mm (mean = 1.54; S.D. = 0.05); elytral length: 1.0– 1.1 mm (mean = 1.04; S.D. = 0.04); greatest elytral width: 0.65–0.70 mm (mean = 0.69; S.D. = 0.02); greatest pronotal width: 0.55–0.60 mm (mean = 0.58; S.D. = 0.03); greatest depth: 0.45–0.55 mm (mean = 0.52; S.D. = 0.04). Body 2.21– 2.29 × as long as elytral width (mean = 2.23; S.D. = 0.03), convex, opaque on dorsum, dark yellowish brown; antennae, palpi and legs yellowish brown.

Head convex, slightly concave in the middle of vertex, sparsely and inconspicuously punctate; punctures uniform in size, each bearing one short and robust yellowish bristle; intervals among punctures finely reticulate; sides of clypeus angulate; antenna with 3rd segment as long as 4th; 5th to 7th subequal, each one with half the length of the 4th; 8th to 10th forming a loose club, each club segment bearing four “sensillifers” formed by a group of short, sparse and not well­organized sensillae.

Pronotum 0.82–0.92 × as long as broad (mean = 0.86; S.D. = 0.05), convex; anterior margin broadly rounded, slightly curved inward in each side; anterior angles not produced; lateral margins narrowly ridge, finely crenulate, barely visible for their entire lengths from above; dorsum irregularly punctate; punctures uniform and similar in size to those on head. Each bearing a short, robust, yellowish bristle; intervals among punctures finely reticulate. Scutellum pentagonal ( Fig. 1 ). Elytra 1.43–1.57 × as long as broad (mean = 1.51, S.D. = 0.05), 1.82–2.22 × as long as pronotum (mean = 2.09; S.D. = 0.16); sides subparallel in basal two thirds, then gradually converging to apex; lateral margins not visible from above, except for basal corners; disc with dual and seriate punctation, but base subseriate, the larger punctures being two to four times the size of the smaller ones; the smaller punctures inconspicuous, bearing bristles similar to those on pronotum.

Prosternal disc weakly tumid medio­longitudinally; prosternal process parallel­sided, almost the same length as prosternum and slightly curved ( Fig. 2 ). Outer angle of protibial apex angulate ( Fig. 3 ). Metasternum with a very small median suture (discrimen); disc of metasternum with a small concavity. First ventrite bearing a setose patch ( Fig. 4 ).

Male genitalia ( Fig. 5 ). Eighth sternite subtrapezoidal, with its posterior margin deeply curved inward. Tegmen with parallel lateral margins; basiconical sensillae concentrated at apex; apical margin rounded, with a small but conspicuous emargination at middle; basal margin rounded. Median lobe 0.8 × as long as tegmen, parallel sided in its basal three­fourths, then converging to apex.

Female. Body length (excluding head): 1.55–1.75 mm (mean = 1.64; S.D. = 0.10); elytral length: 1.05–1.20 mm (mean = 1.12; S.D. = 0.08); greatest elytral width: 0.65–0.80 mm (mean = 0.70; S.D. = 0.06); greatest pronotal width: 0.55–0.70 mm (mean = 0.63; S.D. = 0.06); greatest depth: 0.50–0.60 mm (mean = 0.54; S.D. = 0.04). First ventrite without a setose patch.

Other specimens examined. Paratypes (51): 21 males, 30 females, same data as holotype. Besides a locality label, all paratypes have a yellow label with their identifications.

Host fungus. Bracket mushroom (Basidiomycetes: Polyporaceae sensu lato): Pycnoporus sanguineus and an unidentified species, both species growing in a fence made of “Candeia” wood ( Vanillosmopsis sp.).

Etymology. This species is named in honor of Paulo Sérgio Fiuza Ferreira. Dr. Fiuza is currently a Major Professor in Universidade Federal de Viçosa (UFV), and is also the curator of the collection of “Museu Regional de Entomologia” (UFV/CCB). He is also advising and coadvising four graduating students, three of them working with Ephemeroptera. As a taxonomist, he has a huge experience with Miridae and is, with no doubt, one of the most important specialists of this family.

Distribution. Known from a single field collection in Araponga (Minas Gerais State, BRAZIL; 20º40’S, 42º31’W).

Depositories. Holotype (male), 1 male and 1 female paratype at “Museu de Zoologia da Universidade de São Paulo”, São Paulo, SP, BRAZIL. Two specimens will be deposited in the following personal or institutional collections: Mr. Ayr de Moura Bello, BRAZIL; Mr. Rafal Ruta, POLAND; Mr. Roman Królik, POLAND; Dr. Paulo Sérgio Fiuza Ferreira, “Museu de Entomologia da Universidade Federal de Viçosa”, Viçosa, MG, BRAZIL; Dr. John F. Lawrence, Australian National Insect Collection, CSIRO Entomology, Canberra, AUSTRALIA; Dr. Philip D. Perkins, Museum of Comparative Zoology, Harvard University, USA; Dr. Chuck Bellamy, California State Collection of Arthropods, Sacramento, USA. Remaining paratypes (35) are in the personal collection of the junior author.
