Tribe Hastini Emeljanov, 1979


Compiler and date details

13 September 2010 - Murray J. Fletcher

 

Introduction

The best known and most common species of Australian Dictyopharidae were transferred to this tribe from the Dictyopharini by Emeljanov (1979). The tribe, at that time, was only known from Australia but Emeljanov (2008) transferred the two South American genera Dorimargus Melichar (with one species in Brazil) and Eudictya Melichar (with two species in Argentina) into Hastini giving the tribe a more Gondwanan distribution.

Introduction

This genus was revised by Song & Liang (2013) who recognised six species, two of which are recorded for Australia, the others being in Western Province of Papua New Guinea, Timor and Fiji. Song & Liang (2013) also provided a key for the separation of the species.

Diagnosis

Body slender; head elongate, pointed, with apex slightly deflected upward. Coryphe oblong triangular, projecting forward beyond eyes at distance equal to their half length; lateral carinae with bend depression (constriction), thicker before constriction, median carina very fine after constriction. Lateral sides of process visible in dorsal view at sides of coryphe. Coryphe concavely arcuate in lateral view, curved slightly more strongly in posterior part. Metope in lateral view straight in basal half, gently convex in apical half; bend becoming stronger toward apex of head. Metope parallel-sided from clypeus to upper margins of eyes and slightly above, then cuneiformly narrowed toward apex, without prominences opposite bases of antennae. Intermediate carinae near clypeus equally distant from each other and from sides of metope, sharp along entire length, with weaker median carina running along bottom of groove between them. Lateral carinae slightly diverging, then also smoothly converging; lateral areas in front of eyes bent laterad. In lateral view, lateral carinae diverging from intermediate carinae in basal third of metope, then running in parallel. Apical callus small, vertical; lateral carinae of metope approaching to coryphe at distance equal to length of apical callus. Clypeal border of metope gently concave. Antennae small, 2nd segment globose. Postocular swellings small, distinct, continuing toward antenna as short vanishing carina. Rostrum short, only reaching apices of hind coxae. Ultimate segment 1.5 times shorter than penultimate one. Posterior margin of coryphe in form of not sharp keel. Pronotum rather long; disc rather weakly projecting forward, anterior margin arcuate, median carina well-developed, lateral carinae sharp but weakened in posterior part, terminating at distance from posterior margin equal to 1/3 of their length. Lateral carinae of pronotum entirely developed, collateral carina stronger, pectoral carina absent. Posterior margin of pronotum gently obtuseangularly concave. Mesoscutum with 3 distinct carinae; lateral carinae parallel in posterior part, slightly curved medially at anterior margin. Tegulae without carina. Fore wings elongate, corium widened distally, membrane semi-elliptically rounded. Stem of ScRM about half as long as basal cell. Stigma narrow, with 1 or 2 cross-veins. Vein ScR branching before stigma, claval veins joined in basal 2/5 of clavus. Fold of fore wing crossing first intermedial cross-vein. Hind tibia with 4 lateral and 7 apical teeth, 1st and 2nd segments of hind tarsus with more than 20 teeth (20–22) (Emeljanov 2008).

Externally, Anasta is very similar to Dictyophara s. str. Germar, 1833 in many morphological characters, but a long conjunct stem of Sc+R and M in the forewings and different female genitalia in Anasta assign it to the tribe Hastini. Geographically, Anasta is distributed in the Australasian region, while Dictyophara is restricted to the Palaearctic region. Anasta can be distinguished from the Australasian genus Articrius Emeljanov by the cephalic process being relatively narrow, gradually tapering to the apex and the lateral carinae of the mesonotum nearly parallel and not bifurcated (Song & Liang 2013).

Introduction

This species was described from three specimens collected during Prof. Handschin's 1930-1932 collecting excursion to Indonesia and northern Australia at "Australie N.: Burnside". The precise locality of Burnside is not known but plotting Handschin's journey using the dates and localities given in Lallemand (1935) indicates that it is in the northern part of the Northern Territory, SE of Darwin. A search of the NT Place Names Register (http://www.ntlis.nt.gov.au/placenames/) returns three localities, all in this region:Burnside Homestead at 13°28'S 131°25'E, Burnside Mine at 13°30'S 131°21'E and Burnside Road, Marrakai. Any of these could have been the source of Lallemand's syntype series. Song & Liang (2013) recorded the species from Lockerbie in far North Queensland.

Diagnosis

Verte, sauf les yeux, l'extrémité des épines et des crochets des tarses ainsi que trois petites taches sur l'articulation fémoro-tibiale des pattes postérieures, qui sont noirs; élytres et ailes hyalins, à nervures vertes, stigma allongé, bicellulaire, d'un blanc légèrement verdâtre; sur les tibias postérieurs quatre épines: tête en cône allongé, dirigée un peu en haut et en avant, vue d'en haut ses faces latérales sont visibles; vertex deux fois aussi long que large et égale à deux fois et demi la longeuer du pronotum; rostre atteignant les cuisses postérieures. Longueur totale: 11 à 12 mm; tête: 1.5 mm; corps: 7 à 7.5 mm. (Lallemand 1935)

Introduction

Distant (1906) does not give details of the location within Queensland for his type material which appears to be a monotype. Song & Liang (2013) recorded the species from the Tozer Range on Cape York Peninsula in far North Queensland as well as from Papua New Guinea although they highlighted differences in size and in the proportions of the head between specimens from Queensland and those from PNG.

Note: the generation of this complete preview for Hastini Emeljanov, 1979 was cancelled at Anasta prognatha Distant, 1906 owing to the initation of another complete preview for Thudaca heterastis Meyrick, 1893. Only one complete preview may be executed at a time. Previews were generated for 4 of 18 taxa.
