description: <i>Oxyscelio nullicarina</i> Mo &amp; Chen, sp. n. http://zoobank.org/ 51A8DF2B-B68D-4EFD-AEFB-60D9F2A2AA8C Figures 3, 8, 219–228 <b>Description.</b> Female. Body length 3.01–3.30 mm (n=6). Radicle color: same color as scape. Scape color: yellowish. A4: broader than long. A5: broader than long. Antennal club in female: formed, segments compact. Interantennal process: not elongate. Median longitudinal elevation in frontal depression: absent. Frontal depression: concave. Frontal depression sculpture: without transverse or oblique carinae below submedian carina. Submedian carina: strong, formed by a sharp raised carina. Submedian carina medially: without peak. Concavity across dorsal part of frontal depression: absent. Depression extending ventrally from median ocellus: absent. Upper frons: hood-like. Malar area near antennal foramen: without carina or expansion. Malar area at mouth corner: with radiating striae. Smooth strip along posterior side of malar sulcus: absent or not consistently broad. Middle genal carina: absent. Major sculpture of gena anteriorly: rugose; umbilicate-punctate. Major sculpture of gena posteriorly: absent; umbilicate-punctate. Microsculpture of gena anteroventrally: absent. Microsculpture of gena posteroventrally: absent. Median carina extending posteriorly from hyperoccipital carina: present. Hyperoccipital carina: complete, continuous with anterior genal carina. Lateral connection between hyperoccipital and occipital carinae: absent. Area between vertex and occipital carina: irregularly rugose. Occipital carina medially: uniformly rounded. Lateral corners of occipital carina: not protruding. Lateral pronotal area: without bulge projecting towards anterior pit. Epomial corner: weak. Netrion surface anteriorly: not inflected. Mesoscutum anteriorly: steep. Mesoscutal median carina: present and complete. Longitudinal carina between median carina and notauli: absent. Major sculpture of medial mesoscutum anteriorly: umbilicate-punctate; rugose. Major sculpture of medial mesoscutum posteriorly: umbilicate-punctate; transversely rugose. Microsculpture of medial mesoscutum anteriorly: granulate. Microsculpture of medial mesoscutum posteriorly: absent. Major sculpture of mesoscutellum: umbilicate-foveate; longitudinally rugose. Microsculpture of mesoscutellum medially: absent. Microsculpture of mesoscutellum laterally: absent. Mesoscutellar apex: convex or straight. Setae along anterior limit of femoral depression: arising from rows of foveae. Number of carinae crossing speculum above femoral depression: 3. Number of carinae crossing femoral depression: more than 5. Mesepimeral sulcus pits: more than 5. Metascutellum dorsally: concave. Metascutellar sculpture dorsally: with scattered rugae. Median carina of metascutellum: absent. Metascutellar setae: with many dorsal setae. Metascutellar apex: weakly emarginate. Metapleuron above ventral metapleural area: crossed by carinae. Metasomal depression setae: absent. Lateral propodeal carinae anteromedially: strongly diverging. Anterior areoles of metasomal depression: absent. Anterior longitudinal carinae in metasomal depression: absent. Lateral propodeal areas: separated medially. Postmarginal vein: present. Fore wing apex: reaching beyond T6. T1 midlobe: with 4 longitudinal carinae. T1: without anterior bulge. T2: with straight longitudinal striae or rugae. T6: broader than long. Apical flange of T6: exposed apically. Metasomal apex: rounded. Major sculpture of T6: umbilicate-punctate. Microsculpture of T6: absent. <i>Male</i>. Body length 3.20–3.43 mm (n=3). A5 tyloid: carina-like, not expanded. A11: longer than broad. Median tooth of frontal depression: absent. Median lobe of T1: with 4 longitudinal carinae. Metasomal apex: with tiny rounded tubercles. <b>Diagnosis.</b> Both sexes: Frons without elevation between antennal foramen and eye. Hyperoccipital carina present, continuous with anterior genal carina. Medial mesoscutum transversely rugose posteriorly. Metascutellum with dorsal setae. Female: A4, A5 broader than long. T1 with 4 longitudinal carinae. Male: A5 carina-like, not expanded. Frontal depression without tooth-like median protrusion dorsally. T1 midlobe with 4 longitudinal carinae. Apex of T7 with tiny rounded tubercles. <i>Oxyscelio nullicarina</i> is similar to <i>O. convergens</i> but can be distinguished by the setose metascutellum, and the broad A4 and A5 of female. <b>Etymology.</b> The name <i>nullicarina</i> refers to the absence of middle genal carina of this species. The epithet is used as a noun in apposition. <b>Material Examined</b>. Holotype, female: <b>CHINA</b>: Zhejiang, Mt. Gutianshan, 29°15’20”N 118°9’18”E, 18.VIII.2003, Zaifu Xu, SCAU 3015454 (deposited in SCAU). <i>Paratypes</i>: (6 females, 3 males) <b>CHINA</b>: 1 female, Zhejiang, Mt. Gutianshan, 29°15’20”N 118°9’18’’E, 18.VIII.2003, Zaifu Xu, SCAU 3018700 (SCAU); 2 females, Guangdong, Mt. Chebaling, 24°43’N 114°14’E, 21–23.VIII.2003, Jingxian Liu, SCAU 3015455, 3018699 (SCAU); 2 males, Hainan, Mt. Jianfengling, 18°41’N 108°49’E, 12–14.VII.2006, Jingxian Liu, SCAU 3015456, 3018708 (SCAU); 1 female, 1 male, Guangdong, Nanling National Nature Reserve, 9–18.VII.2004, Juanjuan Ma, SCAU 20095891, 200905875 (SCAU); 1 female, Zhejiang, Hangzhou, West Lake, 25.VIII.2003, Qiong Wu, SCAU 2011000651; 1 female, Zhejiang, Gutianshan, 3.VII.2005, Min Shi, SCAU 3040395 (SCAU). <b>Comments</b>. Johnson <i>et al</i>. (2013) reported additional distribution records of <i>Oxyscelio ceylonensis</i> (Dodd, 1920) from China. However, when we examined the two yellowish females and one blackish male identified as <i>Oxyscelio ceylonensis</i> (Dodd, 1920) (deposited in SCAU), it turns out that these three specimens do not match any described species. Based on additional material collected from Zhejiang, Guangdong and Hainan, we describe them as a new species here.
