Amputostypos Sharkey , gen. n.

urn:lsid:zoobank.org:act:83935652-A2F4-4F55-91D3-86BE3DBE7AF4

Type species: Disophrys concolor Szépligeti, 1908 .

Lectotype of D. concolor designated by van Achterberg, 1974.

Amputostypos concolor comb. n.

Etymology: From the Greek words Amputo and stypos, meaning short and stem respectively. Th ese refer to the close relationship with the genus Hypsostypos , meaning high stem. Amputostypos differs from Hypsostypos primarily in lacking high ridges surrounding the antennal bases.

Taxonomy: Sharkey et al. (2006) included this generic concept under Hypsostypos , mistakenly thinking that the type species of Hypsostypos lacked posterolateral carinae on the frons.

Distribution: Oriental, East Palaearctic, Oceanic, Australian, African (rare), primarily tropical and warm-temperate, but reasonably represented in moderate temperate localities. No specimens are recorded from Th ailand but we have collected 83 specimens representing 10 species.

Diversity: It is diffi cult to estimate the number of species due to recent changes in generic concepts. Sharkey et al. (2006) divided Coccygidium s.l. into Hypsostypos , Zelomorpha , and Coccygidium s.s., however few new combinations were made. Members of Amputostypos are restricted to the Old World and there are about 12 species recorded for the Oriental region. Bhat and Gupta (1977) included 10 species. Amputostylos corresponds to what they referred to as the Sulana species group of Zelomorpha .

Biology: There are no reliable host records available. Th e short ovipositor suggests that they attack exposed hosts. Many species are pale colored with rather large ocelli and presumably nocturnal.

Phylogenetic Information: Probable sister to Euagathis ( Sharkey et al. 2006) .

Diagnosis: Members are very similar to Coccygidium and Euagathis . Unlike Coccygidium they have relatively short foretibial spurs (Fig. 4b) and the frons lacks lateral carinae (Fig.5b). Unlike Euagathis they have one or two carinae ventrally on the hind trochantellus (Fig. 3a). Members differ from Hypsostypos in lacking the high ridges surrounding the antennal insertions.

Description: Head: Lateral carina of frons lacking (Fig. 5b); interantennal space usually with two weak prominences separated by shallow groove (never high as in Hypsostypos ); gena not extended ventroposteriorly into sharp prominence; labial palp with four segments, third segment not reduced, more than half length of apical segment; apical antennomere acute. Mesosoma: Mesoscutum with sculptured notauli; posteroscutellar depression absent; median areola of metanotum surrounded by well defined carinae laterally and posteriorly; propodeum areolate carinate; posterolateral corners of propodeum elongate; propleuron mildly convex to flat; propodeal pseudosternite well developed, separating hind coxal cavities from metasomal foramen. Legs: Foretibial spur not elongate, about ½ length of basitarsus (Fig. 4b); foretibial spur with setae extending to its apex or nearly so (Fig. 4b); foretibia lacking pegs; tarsal claws bifid (Fig. 2a); midtibia with apical pegs but lacking pegs at midlength; hind femur usually rugose ventrally; hind tibia with 2 apical pegs, posterior peg larger than anterior peg. Wings (Fig. 18b): Rs+Ma vein of forewing incomplete and not tubular throughout; second submarginal cell of forewing triangular and sessile; forewing 3RSb straight to slightly sinuate; hind wing crossvein r absent ; hind wing crossvein r-m weakly indicated as a short nebulous or spectral thickening, i.e., as a depressed line that may or may not be pigmented, near the base of Rs; hind wing Cub present as nebulous or spectral vein. Metasoma: All terga smooth, lacking sculpture; median tergite 1 lacking pair of longitudinal carinae;

median syntergum 2+3 lacking transverse depression separating terga 2 and 3 or with depression barely indicated; ovipositor, decurved, shorter than half the length of the metasoma when fully extended (Fig. 18a).
