(Figures 11–15)
Holotype Male: VENEZUELA. Portuguesa state: Ospino, Santa Barbara, 9o28.695’ N / 69º 33.111 W, 1340 m, 10–11.v.2013, F. Sosa & C. Martins Leg. Collected with light trap. Deposited in the MJMO.
Diagnosis. This species can be differentiated by its light yellow head coloration and its darkly marked, olive green body; the markings are red-wine-colored, and they include the abdominal segments. In addition, the scape has a wide dorsolateral red-wine-colored stripe, and the flagellum is pale yellow. The membrane around the crossveins and gradates series of the forewing is shaded with black, and both the forewing and hindwings have unusually dark markings on the pterostigma.
Description. Head (Fig. 11). Pale yellow; vertex smooth, with paired, crescent-shaped, red-colored, slightly diffuse marks; sides of vertex with red-wine coloration (Fig. 11 A); antennal fossa marked with red medially, laterally; frons pale yellow, unmarked; gena, basolateral margin of clypeus black. Maxillary palpus black, with apex of last palpomere pale; labial palpus pale yellow, lightly shaded with black laterally (Fig. 11 C). Antenna: scape, pedicellus pale yellow, with wide, red-wine-colored, dorsolateral stripe; flagellum pale yellow, with black bristles (Fig. 11 A) Thorax. Pronotum olive green, with wide, red-wine-colored, longitudinal stripe laterally; mesothorax marked with red-wine color on margin of prescutus, scutum; metathorax with round, red-wine-colored marks onto the scutum; pleural, sternal areas pale green; legs pale green, unmarked (Fig. 11 A–B). Wings (Fig. 12): forewings with longitudinal veins pale green, most crossveins brown, pterostigma with elongate black spot, gradate veins shaded with black; hindwing with longitudinal veins, crossveins pale green,pterostigma with short, black spot.
Abdomen. Olive green, each segment with red-wine-colored mark dorsally (Fig. 11 B). Male terminalia (Fig. 13): A1–8 with enlarged, ovate spiracles; circumference of A8 spiracle 1.2 times greater than circumference of callus cerci (Fig. 13 A). T9+ectovate, with acute basilateral corner; callus cerci with ca. 34 trichobotria. S8+9 with ventral margin ca. four times longer than height of anterior margin. Gonarcal arch with rounded, “V” shape; lateral apodemes rectangular (lateral view), with triangular horn on margin of lower corner (Fig. 13 B–E). Female terminalia (Fig. 14):A1–8 with ovate spiracles. T9+ect rectangular, dorsal margin not raised; callus cerci round, with ca. 24 trichobothria (Fig. 14 A–B). Gonapophysis lateralis with dense, long setae; anterior margin sinuous, posterior margin rounded. S7 rectangular; dorsal margin slightly sinuous; ratio of ventral margin length: anterior margin height ca. 1.8: 1. Spermatheca pillbox-shaped, ventral impression deep, spermathecal duct elongate, ca 1.7 times longer than height of spermatheca and velum (Fig. 14 C–D). Subgenitale cordate, lobate dorsally, slightly extended basally (Fig. 14 E).
Measurements (n=3). Head: width = 1.36–1.39 mm. Pronotum: length = 0.65–0.68 mm, width = 0.90–1.0 mm, scape height = 0.29 mm. Forewing: length = 11.67 mm, width = 4.08–4.16 mm, length/width ratio = 2.80– 2.86: 1, intramedian cell length = 0.77–0.84 mm, maximum height of costal area = 0.80 mm, four to five inner, six outer gradates. Hindwing: length = 10.0– 10.41 mm, width = 3.3 mm, length/width ratio = 3.03–3.15: 1, four inner, four to five outer gradates.
Other material examined. Paratypes. VENEZUELA. Portuguesa state: Ospino, Santa Barbara, 9°28.695’ N / 69º 33.111 W, 1340 m, 10–11.v.2013, 3♂♂, 5♀♀, F. Sosa & C. Martins Leg. (MJMO). Collected with light trap; Idem, 1♂, 1♀ (MIZA).
Known geographical distribution. Venezuela (Portuguesa).
Species relationship. U. martinsi sp. nov. is a very full colored species with shaded crossveins and dark pterostigmal spots in both fore- and hindwigs. The most similar species is U. rubricosa sp. nov., but this species has pale green coloration and a diffuse pterostigmal spot on the forewing and none on the hindwing. Furthermore, U. martinsi sp. nov. have all the Psm–Psc crossveins black, whereas in U. rubricosa sp. nov. they are green pale. The male and female terminalia of the two species are also similar; however, the U. martinsi sp. nov. S8 & 9 is considerably longer than that of U. rubricosa sp. nov.
Biological notes: A female laid a cluster of ca. 20 eggs at the tip of an elongate pedicel. Each egg had a short, very slender stalk that connected it to the central stalk (Fig. 15). The deposition of clustered eggs has been reported for other species of Ungla (e.g., U. ivancruzi, U. argentina, U. binaria), and several species of Leucochrysa (Leucochrysa) [e.g., L. (L.). nigrilabris (Banks) and L. (L.) insularis (Walker) (Freitas, 2003; Monserrat & Freitas, 2005; Reguilón 2010; Tauber et al. 2013). In the study here, the eggs did not show embryonic development and they did not hatch; no larvae were obtained.
Etymology. The species is named in honor of Caleb Martins, Msc., a Brazilian biologist who has studied chrysopids from Venezuela and Brazil. He was a fellow student in the lab of Sergio de Freitas.
