COLYDIIDAE (1)

INTRODUCTION

1 am greatly indebted ta the authurities of the Institut des Parcs Natio­naux du Congo et du Ruanda-Urundi, fol' Lheir kindness in allowing me to study lhe Colydiidae col1eclec1 by NI. H. DE SA EGER and his collabol'ators in the Parc National de la Garumba,

The collection assembled by Lhese workel's arnuLtnLecl La 939 specimens l'efel'able la 35 species disl1'ibuted among 20 genel'a. Fl'Om the position and size of the Parc, lhiswould appeal' la l'epl'e, ent Cl most lhorough sampling of the fauna. In lhe whole of Aft'ica the Colydiid fauna as known at present consisls of 162 species assigned ta '16 genem. A majOl'ity of lhese s[lecies are found in lhe foresls of west Ah'icu und the Congo basin, 108 species being sa far recorded hom the Cungo as a \\1hole. rfhe Parc Nationul de la Gal'llmba, bordel'ing as il does on the southern Sudan and being in large part savannu-type countl'y, would not be expected la harboul' such a lal'ge number of species as doe' the vast, for'ested area of cenlral Congo.

ln view of the interesling geographical loculion of Lhe Parc and the excellent matel'ial at my disl:oS;ll, 1 have thought it beller to give much more U1an a simple list and descriplions of nevv pecies and genem wher0 necessary. In order ta relute the fauna of the] Ul'C la that of Ah'icu as a whole and so determine, as far as possible, its affinities, 1 have provided al the outset a key ta the Aff'ican tribes of Colydiidae. \iVhere a tl'ibe is

represented among the faunu of the Parc, a key to al! African genera within that tribe is given. Similarly, when a genus in that tribe is recorded from the Parc, a key to ail its African species has been added.

Tribes not known fmm the Parc are recorcIed in the key with their distribution. Likewise, species not yet found in the Parc, but inclucIed within genera recorded therefrom, are contained in the key to species. Species colJeGted by M. H. DE SAEGER and his helpers are aU described, or' redescribed, and aIJ the genera to which they belong are diagnosed. The other species assigned ta these genet'a are recorded in the present paper; a reference is given to lheir original description and a summary of theit' distribution as ü is knovvn at present is provicIed. \tVhere ü is thought that ü might pmve useful, a few notes on lhe appearance of the non-parc species are given. Genus

In this way it is hoped 10 show how lhe Parc species compare in cre

number, appearance and distribution with the l'est and to make easy the identification of any othet' known African species which may, at ,'[ foii

laler date, be found within the Garamba Parc area. iTf/,}Groups and species not yet found \,vithin the Parc National de la

Garamba are recorded within [ ].

(;~ILUSACKNOWLEDGMENTS.

This work has involved the study of much olher material, aparl from that collected by M. DE SAEGER and his colleagues. A major portion is in GelLus the British Museum (Nat. l-Iist.) , London and without facilities for its

mil examination, this analysis would not have been possible.

Many other institutions and individuals have been most helpful in GellUS

supplying material, including certain types, and my grateful thanks are ofr

again due. These other sOUl'ces ar'e: The South African Museum, Cape­town; the Muséum d'Histoire Naturelle, Paris; the Zoologisches Museum mil

Microprius terrenus FAIRMAŒE, 18G8, Ann. SOC. Ent. Fr., (4), 8 : 779. Microprius reticulatus GHOUVELLE, 1908, Rev. d'Ent. Caen, 27: 151 (syn.

nov.).

Length 2,4-3,5 mm. Breadth 0,8-1 mm.

This species is very similar in general appearance to NI. contusus, but is distinguished by the frontal granules which are more widely separated and interconnected in such a way a 10 produce three rather vague rings which are themselves interconnected by ridges. The elytral carinae of M. terrenus af'e slightly more strongly raised than they are in the case of M. contusus.

Holotype : ? In the Muséum d'Histoire Naturelle, Paris. Simon's Gay, Cape of Good Hope, Cape Province.

Distribution. - Cape Pl'ovince, Natnl, Southern Rhodesia.

The synonymy given above is based upon the examination of a cotype of M. rf'liculatus Gll0UVELLE. There is no doubt that it is the same species as thal described by FAIRMAŒE.

In facies, Colobicus is most closely relilled to Cicones CURTlS (p. 16), but l'aIls in Cl differ'ent section of the key to genem on account of its eleven­segmenled antennae with a two-segmented club. Il closesl African relative is Sp1'ecodes (p. 39), l'rom which il differs asindicated in the key to species. Another difference bet,veen the Iwo genera lies in the elytral setne; in Sprecodes they are more or less erect, whereas in species of Colobiclts they are l'ecu mbeo t.

Four species of rolobicus have been described from African material. One of these, C. seria/us KOLBE (1897), is almost certainly inconectly placee! in the genus, but is impossible ta l'eassess in the absence of materiaJ. Another, C. amplia[us FAfRMAERE (1882) is apparently cOl'rectly placed in Colobicl.ls, but the descl'iptionis bl'ief and lacks the details which are necessary for specific identification. The remaining species are disLinguished in Lhe key below. C. speciahs GROllVELLE is very closely l'elaLed to C. parilis PAscm~ of tropical Asia. C. rninl.l[Us POPE is very distinct and may, vvhen more is known of the fnrnily, prove 10 be more happily accornrnodaled in il new genus.

Sùsylus is a widesjJlead genus, cccul'ing in lhe Americas, Afl'ica and Asia. IL is closely l'elated ta CraSped01Jhilus HEINZE (1943, 1<;nt. Dl., 39 : 115), but differs as explained in the key to genem. Il also shows distincl affiniLies with the Bothl'idel'ine genus ;lntibothrus SHARP (p. ~5), emphasi­sing lhe close l'elationship between the Uerrtlaphrini and the /Jolhriderini.

Sexual dimol'phism: the lwo s xes al'e usually very like each other, but in genel'al the males may be separuted by virtue of their having a legs strongly sculplured and legs noticeahly pubescent clypeus and by the antennae being equipped with shodel' setae.

Although it has narrowly eparated nnterior coxae and the prosLernal process is expanded behind the anterior coxae to form a simple lobe, the intercoxal process of the first audominal segment is clearly tmn­cate apically and so the genus is included within the BOlhriderini.

T y P e s P e cie s: BOlhrideres joveicollis REI1'TER.

Small tO model'ate size; elongate-elliptical or cylindricai. He a d with eleven-segmented antennae, the lasL two segmenLs for'ming a symmetrical club, uitimate segment distincUy smallel' thelO the one preceding; eyes not prominent, ovate, bl'oadest above; antennal gl'ooves beneath head long, clearly marked. Pl'O no tu m trapezoidal or more 01' less cordifol'm, nu'ely cylindf'ical; anterior rnal'gin unbordered; antel'iol' angles usually at least slighlly produced; laterai mar'gins usuüIly with a distinct and entil'e lateral border. Ely t r a elongate, elliptical 01' pal'aLlel-sided; evenly rounded to 01' slightly sinuate befol'e apico utural angles; alternate intervals between stl'iae carinate; even intervals punctate, striate, or both. Prostel'l1um with antel'ior coxae broadly separated by intel'coxai process which has a tt'ansverse sulcus bet\\'een coxae (fig. 35). Melasternum without postcoxal r·idges. Fir'st abdominal segment without postcoxal ridges. Le g s with antel'ior tibiae generaLly expanded to"\vard al ices, apices with a we]]-marked exLernal spur; inLel'mediate and hind tibiae less broadly expanded Loward apices, external SpUl'S freC[uently less well-marked; Lat'si with basal segment sometimes slightly longer than the one following, usua]]y thicker.

BOlhrideres was, unLil now, one of the lal'gest of the COLYDIID genera, including species fl'om every continent. EruCHSON, in hi original tl'eaLmenl of the genus included B. conlraclus (OLIV.) from Europe, B. geminatus (SAY) fl'om America, B. illusu (JE\VMAN) fl'om AusLntlia and B. vittatus (NEWMAN), also fl'om Austl'alia. So constituted, the genus included considerable struetul'al variations of a more 01' less fundamental nature. Now that many more species have been added to the genus, it is cleal' that the original conception covered al least two distinct gl'OUPS of species. These groups are sufficiently different to wal'ntnt genel'ic separation.

In the EUl'opeü,n and American species, the pf'Ostemal pl'ocess, an important stl'uctme Laxonomically, differs fl'om that of other known species in that il is not thickened and expanded latel'ülly behind the antel'ior coxae. In fact the anterior coxae ovedap the hind bordel' of the prosternum when the insects are viewed dil'ectly from below (fig. 36). Also the prosternaI pl'ocess usually shows no transverse division between the coxae as it does in othel' species. Less conslant differences are the absence of laleral bordel' lo the pronotum and the relatively longer antennae of the Eur'opean and American species.

Fo,' these reasons it is cleady necessary to separate lhe European and American pecies from lhe l'est of the gemls al present caUed BOlhr-irlcres.
