A new species of genus Hoplocryptus Thomson (Hymenoptera, Ichneumonidae, Cryptinae) and a key to species from Oriental and Eastern Palaearctic regions

Abstract A new species of Cryptinae, Hoplocryptusqingdaoensis Sheng, Wang & Schwarz, sp. nov. collected from Qingdao, Shandong Province, in the north border of oriental part of China, is described and illustrated. A key to species known from the Oriental and Eastern Palaearctic regions is provided.

In the last two years the first two authors have been exploring the mountains in Qingdao (Laoshan Natural Reserve), Shandong Province, situated along the Yellow Sea in the northern border of the Oriental part of China, and have collected large numbers of ichneumonids. In this article, one new species, collected in this area is described.

Materials and methods
Specimens were collected with interception traps (IT) proposed by Li et al. (2012) in Laoshan Natural Reserve, Qingdao, Shandong Province, P.R. China.
Images were taken using a Leica M205A Stereomicroscope with LAS Montage MultiFocus. Morphological terminology is mostly based on Gauld (1991).
Type specimens are deposited in the Insect Museum, General Station of Forest and Grassland Pest Management (GSFGPM), National Forestry and Grassland Administration, People's Republic of China.

Type-species. Hoplocryptus binotatulus
Diagnosis. Ventral margin of clypeus with a more or less distinct tooth or tubercle (rarely somewhat paired). Mesoscutum with distinct punctation on a polished or subpolished background. Fore wing with sides of areolet subparallel or moderately narrowed anteriorly. Often both transverse carinae of propodeum entirely developed. Dorsolateral carina of first metasomal tergite usually distinct basal of spiracle (best seen in dorsal or dorsolateral view), its postpetiole rather weakly convex dorsally and not or only rather weakly wider than petiole. Second tergite with distinct and usually moderate sized punctures. Ovipositor compressed and its tip with rather regular and subvertical ridges on lower valve.
Remarks. This genus morphologically resembles Aritranis in having sides of areolet parallel or moderately convergent anteriorly, 2m-cu straight or more or less sinuate, hind wing with M+Cu moderately to strongly arched, lateral longitudinal carina of propodeum absent, first metasomal segment without a lateral tooth basally and with its spiracle at or not very far behind its mid-length; but it can be distinguished from the latter by its dorsolateral carina of first metasomal tergite usually distinct basad of spiracle (best seen in dorsal or dorsolateral view), its postpetiole rather weakly convex dorsally, ventral margin of clypeus with a more or less distinct tooth (rarely paired teeth). Hosts are aculeate Hymenoptera. Aritranis: dorsolateral carina of first gastral tergite absent (or more rarely indistinct) basal of spiracle, postpetiole rather distinctly convex dorsally, ventral margin of clypeus without a tooth, except in the Aritranis nigripes group. Hosts are Lepidoptera and Coleoptera as far as known.

Key to the species of Hoplocryptus known from the Oriental and Eastern Palaearctic Regions (Female only)
This key does not include H. egregius (Kokujev, 1909) as its female is unknown.

1
Clypeus with broad, blunt apical median tooth which has often a slight depression medially. Distance from vein 2rs-m to 2m-cu shorter than distance from 2m-cu to 3rs-m. Scutellum and median portion of hind tarsus often white. Diagnosis. Propodeum rather long. Metasomal tergites 3-6 with even dense and unclear punctures. Second metasomal tergite (Figs 8,9) slightly longer than its apical width. Ovipositor sheath 0.7 × as long as hind tibia. Apical portion of dorsal valve of ovipositor ( Fig. 10) with 6 small tubercles. Face (Fig. 2) with large lateral white spots. All tergites (Fig. 8) with posterior white bands.
Description. Female. Body length 11.0 to 11.9 mm. Fore wing length 7.0 to 7.4 mm. Ovipositor sheath length 2.3 to 2.4 mm.
Head. Inner margins of eyes slightly convergent ventrally. Face (Fig. 2) medially slightly convex, 1.4 × as wide as long, with dense, indistinct punctures and opalescent hairs; lateral portion shagreened; upper margin with a small median tubercle. Clypeus 1.9 × as wide as long, slightly evenly convex; dorsal portion with dense punctures, ventrally smooth, ventral margin almost truncate, with a strong blunt tubercle medially (Fig. 2). Labrum almost semicircular, ventral margin with long brown hairs. Mandible with dense punctures and yellowish white hairs, upper tooth approximately as long as lower tooth. Malar area finely shagreened. Malar space 0.7 × as long as basal width of mandible. Gena with distinct punctures (Fig. 3). Vertex (Fig. 4) with dense distinct punctures. Postocellar line 0.8 × as long as ocular-ocellar line. Frons with a medio-longitudinal carina. Head behind the eyes in dorsal view weakly narrowed. Antenna with 32 flagellomeres. Ratios of lengths from first to fifth flagellomeres: 1.9:1.7:1.6:1.2:1.0. First flagellomere 8.0 × as long as wide. Occipital carina complete, reaching hypostomal carina distinctly above base of mandible. Hypostomal carina distinctly elevated.
Remarks. This new species is similar to Hoplocryptus alboanalis (Uchida, 1952) by the characters: Clypeus with a strong smooth blunt tubercle medially; notaulus strong on anterior half of mesoscutum. anterior and posterior transverse carinae of propodeum complete; ventral valve of ovipositor with strong edges; mesosoma almost entirely black; median portion of flagellum, at least ventral profiles, white; and can be distinguished from the latter by the following combination of characters: Fore wing vein cu-a basad of Rs & M by about 0.3 times length of cu-a. Posterior transverse carina of propodeum (Fig. 7)
