Diagnosis.

Schoenlandella angustigena sp. nov. can be distinguished from other Iranian Schoenlandella species by having the following combination of characters: gena apparently shorter than eye length in lateral view (Fig. 2C ); hind basitarsus longer than combined length of 2nd-4th tarsomeres (Fig. 2E ). Hind wing mostly infuscate, hyaline at basal fourth, apically gradually darkened. S. angustigena sp. nov. is similar to the Egyptian species, S. acrenulata (Fischer, 1958), but S. angustigena sp. nov. differs from S. acrenulata by possessing a greater number of antennomeres, pale upper face and glossa, pale scutellum and propodeum, relatively short hind tibial spur and long ovipositor sheath,

Description.

Body 4.90-6.25 mm. Head. Eye densely setaceous with short interommatidial setae. Flagellum 33-36-segmented. Length of gena ~0.79 × longer than eye length in lateral view (37:47) (Fig. 2C ). POL ~0.69 × longer than diameter of anterior ocellus (9:13). Face mostly smooth, ~1.01 × longer than its width (84:83). Clypeus with two weakly developed tubercles; width of clypeus ~2.06 × longer than its length (70:34). Galea elongate ~1.97 × longer than clypeus height (67:34) (Fig. 2C, D ). Mandible bidentate. 5th maxillary palpomere 0.89 × longer than apical palpomere (17:19). Mesosoma. Notauli entirely crenulate and acutely meeting at base (Fig. 2B ). Scutellar sulcus broad, with 5 or 6 crenulae. Length of scutellum 0.97 × longer than basal width of scutellum (68:70). Postscutellar depression crenulate, as long as anterior width of dorsellum. Dorsellum without median carina. Pronotum medially sculptured, carinate-rugose. Mesopleuron mostly smooth. Precoxal sulcus medially crenulate not reaching anterior and posterior margins of mesopleuron. Episternal scrobe shallow and wavy. Posterior mesopleural furrow entirely crenulate. Metapleuron anteriorly smooth, posteriorly rugose, groove between metepimeron and metepisternum crenulate. Propodeum mostly rugulose; propodeal spiracle ovoid; median areola of propodeum well defined with carinate margin, carinate margin narrowly meeting at both anterior margin of propodeum and nucha, its median width as long as its median length; transverse carina of propodeum medially strongly developed and reaching lateral margin of propodeum. Legs. Fore basitarsus ~1.13 × longer than combined length 2nd-4th tarsomeres (63:56). Mid-basitarsus as long as combined length of 2nd-4th tarsomeres (70:70). Maximum width of hind femur ~1.72 × longer than apical width of hind tibia (50:29); cup-like projection of hind tibia absent; basal spur on hind tibia ~0.66 × longer than basitarsus (71:107). Hind basitarsus laterally slightly expanded, but not expanded as in Hartemita Cameron, 1910, ~1.13 × longer than combined length 2nd-4th tarsomeres (107:94) (Fig. 2E ). Claws pectinate with obtuse apical tooth. Wings. Forewing wing length: ~5.71 mm. Hind wing length: ~4.66 mm. Forewing apically infuscate; 1r absent; 3r basally spectrally present (7♀, 1♂) or absent (1♀); 3RSb broken basally, angled at basal third; second submarginal cell elongate; 1a absent. Hind wing infuscate mostly, hyaline at basal fourth; apically gradually darkened; r entirely nebulous and pigmented; RS tubular at base, apically nebulous and pigmented; M+CU apparently shorter than 1M; M tubular at base, apically nebulous and entirely pigmented, gradually fading apically; 2-1A present as basal stump. Metasoma. T1 ~1.14 × longer than its apical width (83:73). T2 with a pair of curved submedian grooves, anteriorly deeply impressed, posteriorly gradually weakened (Fig. 2F ), median length of T2 0.53 × longer than median length of T3 (31:59). Fourth and fifth metasomal sterna membranous posteriorly, medially unfolded. Hypopygium slightly impressed medially but unfolded, acute apically, its surface entirely sclerotized (Fig. 2G ), its length 1.26 × longer than its height in lateral view (88:70). Ovipositor sheath slightly downcurved and gradually expanding from base to apex, anteriorly bare posteriorly densely setose with long setae, length of protruded ovipositor sheath ~0.53 × longer than hind tibia (109:207). Ovipositor downcurved.

Male. Same as female except for body length and coloration. The body length of male is slightly shorter than females. The medial mesonotal lobe and ventral mesopleuron are pale in the male specimen.

Color.

All specimens are mostly pale, and the following areas are melanic: antenna, vertex, frons, apical mandible, galea, median mesonotal lobe (mostly), ventral mesopleuron, inner hind tibia apically, apical hind tarsus, and ovipositor sheath. Wings apically infuscate, stigma mostly melanic except for base. Five specimens have a melanic mesonotal lobe and a pale ventral mesopleuron, however they share all other morphological characters with other members of S. angustigena .

Host.

Unknown.

Distribution.

Members of S. angustigena sp. nov. are known from Bandar Abbas, Minab and Rudan, as well as Abu Musa Island, Hormozgan, Iran (Fig. 3 ).

Etymology.

From the Latin, angusti -, meaning “narrow” and gena, meaning “cheek”.
