Kodormus barberi ; Gil-Santana and Alencar 2001: 173 [checklist; misidentification].

Notes.

Gil-Santana and Alencar (2001) based on a male specimen from a Natural Reserve in Linhares, Espírito Santo State, Brazil, included Kodormus barberi in a checklist of Reduviidae of this locality. However, a re-examination of the specimen from Linhares made it clear that it belongs to the new species, K. davidmartinsi sp. nov., with the designation of this specimen as the holotype. An additional specimen from the same locality was included as a paratype.

Type material examined.

Brazil, Espírito Santo: Linhares, Reserva Natural Vale, 19°09'S, 40°04'W, José Simplício dos Santos leg., male holotype, xi.1990 (MNRJ); same locality and collector, 1 male paratype, 11.xii.1987, CTIOC n° 13832 (CTIOC).

Diagnosis.

Kodormus davidmartinsi sp. nov. and K. barberi may be separated from other species of the genus by the presence of connexival margins of segments III-V lobulated. These species may be separated from each other by the larger lobulated portion of connexival segment V in K. davidmartinsi sp. nov. Additionally, K. davidmartinsi sp. nov. has smaller integumental setigerous spiniferous processes, shorter processes of disc of fore lobe of pronotum, humeral angles, scutellum and rounded latero-distal margins of abdominal segment VII. In male genitalia, the medial process of pygophore in anterior view, is subtriangular in K. davidmartinsi sp. nov. and spiniform in K. barberi .

Description.

Male. Figs 91 - 104 . Measurements (mm) (holotype / paratype): Total length: 20.5 / 21.5; head: total length (excluding neck, lateral view): 3.2 / 3.1; maximum width across eyes: 2.4 / 2.7; length of anteocular portion: 1.6 / 1.6; length of postocular portion: 0.8 / 0.7; interocular space (synthlipsis): 1.0 / 1.1; transverse width of right eye: 0.7 / 0.8; length of right eye: 0.8 / 0.9; lengths of antennal segments: scape: 1.3 / 1.4; pedicel: 3.0 / 3.0; basiflagellomere 0.8 / 0.6; distiflagellomere: 0.8 [approx.; very curved] / absent; lengths of labial segments: II [first visible]: 1.6 / 1.7; III: 1.4 / 1.6; IV: 0.9 / 0.9. Thorax: pronotum: length of fore lobe (at midline): 1.9 / 1.9; length of hind lobe (at midline): 1.8 / 1.8; width at posterior margin: 4.7 / 5.0. Fore legs: length of femur: 5.4 / 5.6; maximum width of femur at mid portion: 1.3 / 1.4; length of tibia: 5.2 / 5.4; length of pad: 0.1 / 0.2; length of tarsus: 0.7 / 0.8; middle legs: length of femur: 6.5 / 7.2; maximum width of femur at mid portion: 0.45 / 0.45; length of tibia: 6.4 / 7.5; length of pad: 0.2 / 0.2; length of tarsus: 1.5 / 1.5; hind legs: length of femur: 10.0 / 11.5; maximum width of femur at mid portion: 0.5 / 0.5; length of tibia: 12.8 / 13.8; length of tarsus: 1.8 / 1.9. Abdomen: length: 11.2 / 11.7; maximum width (measured between outer margins of anterior portion of sternite V): 6.1 / 6.5; maximum distance between outer margins of lobulated prominence of connexival segment V: 9.2 / 8.8. Coloration (Figs 91-93 , 96 , 97 ): generally dark brownish with ill-defined scattered pale portions or markings on head, femora and sternites; hemelytra, except basal portion, paler, more in the paratype. Antenna pale brownish; scape with irregular scattered dark small markings; apex of pedicel dark. The following portions variably paler: glabrous areas of head and fore femora, more intensively in the holotype; inferior margin of fore supracoxal lobe; upper portions of lateral surfaces and apices of femora; a pair of linear markings at basal portions of tibiae; median portion of tergites I-V (Fig. 96 ), progressively in less extent from the former to the latter; margins of sternites between segments II-VI; on the latter, at each lateral side, a pair of rounded (paratype) or irregular (holotype) small markings on basal margin of these segments and another similar markings between basal and distal margins (Fig. 97 ). Structure and vestiture (Figs 91 - 97 ): Postocular region of the head with only one ramose setigerous process posterolaterally at each side (Fig. 94 ). Processes of scutellum and humeri short. Fore trochanters with two pairs of spiny tubercles on internal surface. Fore femora with a basal group from two to four spiny, relatively small, rounded tubercles, a midline row with eight spiny rounded tubercles and two (holotype) and four (paratype) others close to this row on anterior surface. Fore tarsi bi-segmented; the second segment ~ 3 × as long as the first segment (Fig. 95 ). Connexival margins of segments III-VI lobulated; those on segments III-V have the external margin sinuated at median portion and a short spiny prominence at latero-distal angle in holotype, while in paratype the external margin is faintly curved without spiny prominences (Figs 91-93 , 96 , 97 ). Membrane of hemelytra not reaching apex of abdomen (Figs 91-93 ). Lateroapical margins of abdomen curved, slightly prominent (Fig. 96 ). Male terminalia (Figs 98-104 ): medial process of pygophore subtriangular in anterior view (Fig. 100 ).

Etymology.

The new species is named in honor of Dr. David dos Santos Martins, researcher of the Instituto Capixaba de Pesquisa, Assistência Técnica e Extensão Rural (INCAPER), Vitória, Espírito Santo, Brazil, for his great contribution to the knowledge of the entomofauna of the State of Espírito Santo where the new species was found.

Distribution.

Brazil (State of Espírito Santo).
