Acridoidea of south-west Angola ()

BY

JOYCE B. MASON. (London).

INTRODUCTION.

This paper is a contribution to descriptions of the fauna of Acri- doidea of Angola. It relates to a collection of 407 specimens for- warded by Dr. José Passos de Carvalho of the Instituto de Investi- gaçäo Agronómica de Angola. A complete list for the region is given with additional notes in some cases. The specimens were mainly caught in south - west Angola or west Angola in various cultivations. 011e of the main features of the collection was the bright colouration of the hind wings, the inner side of the hind femur and the hind tibiae. Some unusual colouration combinations were noted. The terminology used for the figures of genitalia is similar to that in Dirsh (1956). The terminology used for describing the 9 genitalia was that of Slifer (1939) and Agarwala (1952).

Localities : Muquitixe, 13 - II - 1971, 2 8 8 (J. Manuel) : Chian- ga, 28 - IV - 1968, 1 y (P. Carvalho). This species damages Mucuna stans Welw. ex Bak. —a decorative legume—. The subspecies, forms, and distribution of Taphronota calliparea are rather uncertain. For these reasons I have treated the present material at specific level only. The basic synononymy is given also at specific level. The full synonymy of the subspecies and forms are given by Kevan (1974) in his revision of the genus Taphronota.

Subgenital plate trilobate. Ovipositor of moderate length, external with robust curved valves ; lower valve with small, angular lateral projection ; outer edge of upper valve slightly serrated. Type species Eilenbergia sagitta nov. sp. This genus is related to Pyrgomorpha and Tanita, though more It closely related to Pyrgomorpha, being more slender than Tanita. differs from both genera in the shape of the pronotum ; the dorsum in the is more flattened, the lateral carinae are sharply developed anterior half of the prozona, are parallel then slightly diverging towards the metazona where they are more or less obliterated. In poorly Pyrgomorpha they are irregular and obtuse ; in Tanita they are developed but noticeable in front of the first sulcus of the prozona margin in and in the posterior end of the metazona. The posterior Eilenbergia is obtuse angular but acute, while in Pyrgomorpha and of the Tanita it is widely rounded or rounded. The lower margin anterior part slightly lateral lobe of the pronotum is oblique with the shorter than the posterior part, the posterior comer is pointed, with the point projecting backwards. This genus and species has been named in the honour of in writing this Dr. M. D. Eilenberg whose help and encouragement paper is greatly appreciated.

This species is related to the species of the group similis Uvarov, 1953; poecila Uvarov, 1939, and nana Uvarov, 1953, which are linked together by the down - curved cercus. All these species were origi- nally described from Angola except poecila which is from the Congo. This new species is most closely related to nana but differs from it by the large body size, broader interocular space, shape of fastigium of vertex, broader and more obtuse prosternal tubercle, orange wing and more coarsely granose integurnent. Type locality Caála, 17 km, 25 - IX - 1971 (Gastäo). Allotype locality Caála, 18 km, 14 - IX - 1971 (Correia). Only the 8s holotype and 9 allotype are known. They are tem- porarily deposited in the British Museum (Natural History).

I dissected the phallic complex and found that it is identical with those found in the British Museum collection. However, the specimens in this collec- tion have a general brownish colouration, the tegmina are finely mottled with darker brown spots. The hind wing has a bluish tinge with a slightly infumate apex. The abdominal tergites are mottled dark purple, but mostly dark red together with buff. There are two unclear fascia on the hind femur. On the outer side the hind femora

Synopsis.

A collection of Acridoidea, mostly pests of cultivated plants from west and south - west Angola, was studied. One new genus, Eilen- bergia, and three new species, Eilenbergia sagitta, Eucoptacra granu- lata and Pycnodictya carvalhoi, were described. Some species were newly recorded from this region. Notes on unusual colouration are given and compared with the usual colouration found. Records are given for some of the host plants. The taxa in this paper are arranged according to Dirsh (1975). In this collection the family Pyrgomorphidae is represented by four subfamilies Taphronotinae, Pyrgomorphinae, Chrotogoninae and Atrac- tomorphinae. The superfamily name Acridoidea is retained. In the family Hemiacrididae two subfamilies are present, Spathosterninae and Leptacrinae; in Catantopidae nine subfamilies are represented, Apo- boleinae, Tropidopolinae, Coptacrinae, Calliptaminae, Euryphyminae, Eyprepocneminae, Cvrtacanthacrinae, Catantopinae and Pargainae; in Acrididae six subfamili es are represented, Gomphocerinae, Truxalinae, 0 edipodinae, Acridinae, Gymnobothrinae and Phlaeobinae. «ACRIDOIDEA» OF SOUTH - WEST ANGOLA 131
