Perithemis capixaba View in CoL sp. nov. ( Figures 37–43 View FIGURES 37 – 43 )

Holotype male: BRAZIL, ESPIRITO SANTO, Mutum Preto, Km. 11 , swamp near to forest (20º 45’ 00’’ S – 41º 13’ 60’’ W), 1.IX.1971, N.D. Santos leg. GoogleMaps

Etymology. The species name “ capixaba ” refers to the type locality, the first Brazilian state where the species was collected.

Male (holotype). Head. Labrum yellowish with dark brown setae; anteclypeous oliveyellow; postclypeous and frons yellow, laterally greenish; vertex brownish; occiput brownish, medially diffuse black; rear of the occiput brownish with a black diffuse central stripe; postgenae brownish, 0.5 ventral black. Antennae dark brown. Labium pale. Thorax. Prothorax, anterior lobe black, except for pale anterior margin; middle lobe brownish with two transverse black stripes not reaching middorsal line; posterior lobe brownish. Pterothorax olive­yellow without dark stripes; antealar sinus and carina olive­yellow. Venter of thorax and coxae I–III pale yellowish. Femora and tibiae I–III pale brown.

Wings ( Figs. 42–43 View FIGURES 37 – 43 ): membranes orange, with a diffuse dark stripe from RP 1 to RP 3 at level of 1st and 2nd pnx crossvein. HW with a small diffuse dark spot between the triangle distal margin and RP. Pterostigma yellowish brown, anterior and posterior margins black. FW triangles 2/3 celled, HW 3­celled. Subtriangles 3­celled. Anx crossveins 8½–7½ in the FW, 6 in HW. Pnx crossveins 6– 5 in FW and 4–6 in HW. CuA crossveins in FW 2/1, HW ½. Bridge crossveins in FW 2/4, HW 3.

Abdomen. Brown with dark brown pattern as follows: tergite I with two central spots; II carinae, two circular spots on anterior margin and two semicircular spots on posterior margin; III carinae and two semicircular spots on the posterior margin extending anteriorly as dark brown irregular spots; IV anterior margin, carinae and two longitudinal dark brown stripes (except at black posterior margin,); V–VII anterior margin, middorsal carina and two longitudinal stripes as on V; VIII anterior and posterior margins, middorsal carina and two longitudinal stripes as on V, dark brown between longitudinal stripes at 0.3 posterior; IX anterior and posterior margins, middorsal carina, two longitudinal stripes confluent at anterior and posterior margins; X posterior margin and a triangular spot directed posteriorly from entire anterior margin and reaching posterior margin; first segment of vesica spermalis rounded ( Figs. 37–38 View FIGURES 37 – 43 ); tip of hamuli nearly 0.50 from ventral margin ( Fig. 39 View FIGURES 37 – 43 ). Anal appendages: cerci dark brown, tips black. Epiproct dark brown, slightly shorter than cerci ( Figs. 40–41 View FIGURES 37 – 43 ). Genital plates and eusternites pale brown.

Measurements. Total length (incl. anal appendages) 22.5; Abdomen 15.4, cerci 1.0, epiproct 0.9. FW broken, length from base to nodus 10.8/11.0, HW 20.5/21.0, maximum width of HW 8.7. FW pterostigma 2.2/2.3, HW 2.5/2.6+

Discussion. Perithemis capixaba is most similar in coloration and size to P. mooma a species known from Argentina – Belize – Bolivia – Brazil (Amazonas, Amapá, Maranhão, Piauí, Pernambuco, Sergipe, Alagoas, Espirito Santo, Rio de Janeiro, São Paulo, Paraná, Santa Catarina, Rio Grande do Sul, Minas Gerais, Goiás, Mato Grosso states) – Ecuador – Honduras, Guatemala – Mexico – Panama – Paraguay – Trinidad – Venezuela. The new species differs from P. mooma by a diffuse dark stripe from RP 1 to RP 2 at level of 1st and 2nd post nodal ( Figs. 42–43 View FIGURES 37 – 43 ) (absent in P. mooma ); first segment of vesica spermalis gently rounded (trapezoidal in P. mooma ); basal portion of fourth segment of vesica spermalis triangular (subquadrate in P. mooma ); pterothorax without lateral dark stripes (two difuses in P. mooma ).
