Distribution. Cosmopolitan. Biology. Solitary endoparasitoids of leaf-mining Nepticulidae. Comments. Shimbori et al. (2019) discussed possible apomorphic and synapomorphic character states between Cheloninae and Adeliini. Apart from the synapomorphic characters, the number of antennomeres is considered as plesiomorphic character to some extent (E.M. Shimbori, personal communication). Within the tribe it has been also found (Kittel & Austin 2014; Kittel et al. 2015, 2016) that the division of the propodeum into distinct anterior and posterior parts (in Adelius, Sinadelius and Sculptomyriola) is a plesiomorphic character as it is absent in other genera (in Carinadelius gen. nov., Myriola and Paradelius). It is suggested that the new genus Carinadelius is probably derived from the genus Adelius., Published as part of Ranjith, A. P., Achterberg, C. Van, Samartsev, K.

Ovipositor without dorsal nodus and ventral serrations. Etymology. Name formed by combining the generic name Adelius and ‘carina’, because of the midlongitudinal carina on the propodeum and the incomplete occipital carina. Gender: masculine. Distribution. Oriental region (India). Comparative diagnosis. The ventrally reduced occipital carina and the midlongitudinal carina and vertical lateral carina posteriorly of the propodeum are considered to be apomorphic characters of the new genus. In addition, the new genus exhibits another peculiar character, its propodeum is not divided into anterior and posterior parts by means of a complete transverse carina which separates it from other genera. This carina may be reduced in Adelius. These characters combined separate Carinadelius from other genera within the tribe. In the keys provided by Belokobylskij (1988, 1998), He & Chen (2000), Shimbori et al. (2019) Carinadelius comes close to Adelius because of the smooth metasoma and evenly fused metasomal tergites 1–3. The combination of the smooth metasoma and absence of first and second metasomal sutures places this genus within the group containing Adelius and Myriola. The smooth marginated areas on the propodeum found in Carinadelius are different from those in Adelius + Myriola. Apart from the apomorphic characters Carinadelius exhibits some other interesting characters like absence of fore wing vein r and position of vein cu-a. Carinadelius differs from Adelius in having the unique carination of the propodeum (propodeum without midlongitudinal carina posteriorly in Adelius), ventrally absent occipital carina which is not connected with hypostomal carina (occipital carina complete, connected with hypostomal carina in Adelius), fore wing vein M+CU distinctly curved (more or less straight in Adelius), vein r absent (present or absent in Adelius). Carinadelius is also similar to Myriola in having an undivided propodeum. However, it differs from Myriola in having the following characters: fore wing vein 1-R1 present and long (vein 1-R1 absent in Myriola), malar space distinctly longer than basal width of mandible (distinctly shorter than basal width of mandible in Myriola), fore wing vein r absent (present in Myriola), fore wing infuscated (hyaline in Myriola). The smooth metasoma in Carinadelius separates it from the genera Paradelius, Sculptomyriola and Sinadelius in which metasomal tergites 1–3 are sculptured. Even though other adeliine genera exhibit a fixed number of antennomeres (22 in Sinadelius and 20–21 in other genera), it is found that number of antennomeres is highly variable at least in the genus Adelius (E.M. Shimbori, personal communication).

Foenatopus chinnarensis (Sureshan, 1997) Diastephanus chinnarensis Sureshan, 1997, Bioved, 3, 89���92. Type material. Holotype ♂, India: Kerala, Idukki district, Chinnar (10��30��� N & 77��20��� E, 450 m), 19.xi.1996, Coll. P.M. Sureshan, (ZSIK) Regd. No. ZSI/ WGRC /IR/INV.3598. (Type specimen missing).

(NZC) 10072/H3 (Head missing). Diagnosis. Male. Body length 7 mm. Frons completely yellow with coronal teeth reddish trans-striate, tip of mandibles black; gena yellow; vertex with two trans-carinae turning rugose posteriorly and irregularly punctate; occipital carina indistinct; pronotum with pale brownish yellow near posterior margin, deeply reticulate; axillae and scutellum strongly reticulate; metapleuron deeply reticulate; hind femora ventrally with two tooth; propodeum anteriorly half reticulate, posteriorly with few scattered pits and carinae; first metasomal tergite weakly and longitudinally reticulate, longer than remaining segments, the latter with yellow patches. Female. Body length 13.65 mm, ovipositor sheath length 11.5 mm. Frons transversely striate with oblique striae in between coronal tooth; vertex with three carinae followed by fine transverse striae; neck transversely striae; pronotum rugose-reticulate; mesoscutum finely shagreened posteriorly with scattered pits and shagreened interstices; scutellum with smooth reticulations; propodeum with large close pits and shagreened interstices; hind coxa strongly striate; femora with two tooth and few denticles ventrally; first metasomal tergite shorter than remaining segments; ovipositor sheath with a subapical band. Distribution. Oriental: India (Kerala, Arunachal Pradesh). Host. Unknown. Note. The female specimen of F. chinnarensis designated from Arunachal Pradesh, India pose some confusion in the identity of the specimen. The female species designated shows quite distinct variations in the number of carinae present on the vertex, colouration on the pronotum, metasoma and the sculpturing on the metasoma with the designated holotype (male specimen) from Kerala, India. This is attributed to the possible sexual dimorphism within the specimens (Sheela & Ghosh, 2009). However, authors here feel the species extend beyond the limits of variation and the species to be a novel one. But, with the designated female specimen broken at the crucial part (head missing), it is quite impossible now to designate the same within the limits of variation or as a novel species. Hopefully future sampling of the species in India will allow a broader assessment of the consistency of these variations and novelty of the reported species. The holotype was untraceable, therefore, the above mentioned diagnosis of male is obtained from the original description., Published as part of Binoy, C., Achterberg, C. Van, Kumar, P.
