description: Cryptalyra depressa Azevedo & Tavares, sp. nov.
Diagnosis
Body light chestnut brown; surface of head coriaceous with shallow punctures; ocular orbital carina absent; occipital carina conspicuous, curving ventrally towards mandibles; antennae almost reaching posterior margin of propodeum, 1.85x as long as head length; dorsum of propodeum with wide median longitudinal depression.
Description of female
Length. Body 4.6 mm; forewings 3.0 mm; ovipositor 1.0 mm. Color. Body, antennae, mandibles, palpi, tegulae and legs light chestnut brown; distal two thirds of last flagellomeres and eyes infuscate; wing membranes subhyaline, wing venation light chestnut brown, except stigma darker.
Head. Hypognathous; subglobular, about as high as wide in frontal view, and 0.68x as long as high in lateral view, and 0.72x as long as wide in dorsal view; frons convex, not excavated, 0.49x as wide as head in frontal view and 0.78x eye height; clypeus almost flat, apical margin with pair of median teeth; surface of head coriaceous with numerous shallow piliferous punctures, interspace 1.0–1.5x as wide than diameter of punctures on frons and temporae, 1.0 – 2.0x around ocelli and on genae; punctures elongated and longitudinally oriented with setae on posterior to vertex; eyes large, 0.65x as height as head height, elliptical, anterior margin more convex than posterior margin in lateral view, densely and obviously setose; ocular orbital carina absent; ocelli subtriangular, anterior ocellus preceded by anterior concavity, lateral ocelli followed by postero­lateral concavity, distance between lateral ocelli 1.31x distance between eye and lateral ocellus, maximum diameter of lateral ocelli about 2.0x distance between eye and lateral ocellus; depression of malar space broad and deep, surface smooth without punctures bordered along dorsal, ventral and distal margins by conspicuous carina; occipital carina conspicuous, sharpened behind temporae, curving ventrally towards mandibles; post­occipital carina complete; hypostama triangular and slight concave, hypostomal carina complete and high; antennae 14­segmented, 1.85x as long as head length, scapes depressed, 1.36 x longer than wide, flagellomeres cylindrical, longer than wide, except V – VIII about as long as wide; left mandible with three apical teeth; maxillary palpi 4­segmented; labial palpi 3­segmented, the last one very tiny.
Mesosoma. Mesoscutum, axillae and scutellum coriaceous with sparse, shallow piliferous punctures, which are about 0.5x narrower than those on vertex, interspace 3x wider than the diameter of punctures; median mesosnotal sulcus evenly narrow an deep; mesoscutum 1.54x larger than longer; axillae widely separated each other; scutellum entirely isolated of axilae by wide, foveolate groove, which is narrower anteriorly; pronotum and lower half of mesopleura with interspace nearly polished to weakly coriaceous, upper half of mesopleura with irregular piliferous punctures; pronotal spiracles elliptical; mesoscutum surrounded by carina, except at middle of anterior margin, where carina get into mesoscutum for short distance; notauli as stub joined to posterior margin of mesoscutum; dorsum of propodeum with wide longitudinal depression, evenly wider anteriorly, its inner surface smooth with transverse ridges in a polished background, depression bordered by sharp longitudinal carinae, otherwise disc weakly rugulose beside depression to areolate laterally and posteriorly, postero­lateral corners angularly produced; posterior surface of propodeum concave medially as continuation of depression.
Legs. Fore and middle tibiae not rimmed with stout setae; basitarsus of all legs conspicuously longer than the other tarsomeres; ventral margin of fore and hind basitarsi with comb of stout setae; ventral margin of hind femora with inner carinae on anterior half and with outer stout tubercle on posterior third; claws simple.
Metasoma. Cylindrical, first tergum polished with few setae laterally; second and following terga progressively more coriaceous and more densely setose laterally; ovipositor sheaths distinctly protruding beyond apex of metasoma, apex densely setose; ovipositor 0.48x as long as metasoma.
