Papp, J., 2012, Three new diospiline species from Honduras (Hymenoptera: Braconidae: Helconinae: Diospilini), Linzer biologische Beiträge 44 (1), pp. 601-611 : 604-605

Diospilus subfuscus nov.sp. ( Figs 13-19 )

M a t e r i a l e x a m i n e d: Male holotype and one male paratype: Honduras, Fco. Morazan, San Antonio de Oriente Uyuca, 6 March 1997, leg. C. Hansson. Holotype is in good condition: glued on a pointed card by right side of mesosoma. Paratype is in fairly good condition: (1) glued like the holotype, (2) both flagelli apically deficient, (3) right hind femur invisible owing to the mounting, (4) head turned "backwards": position of oral organs towards mesosoma (owing to the mounting?).

D e p o s i t o r y: Holotype is deposited in the Zoologisk Museum, Lund; paratype is in the Hungarian Natural History Museum ( Department of Zoology ), Budapest, Hym. Typ. No. 12022.

E t y m o l o g y: The species name "subfuscus" of the new species refers to the blackish brown to brown corporal colour.

D e s c r i p t i o n of the male holotype: Body 1.9 mm long. Antenna somewhat shorter than body and with 21 antennomeres. First flagellomere 2.4 times and penultimate flagellomere 1.6 times as long as broad, flagellum evenly thick. Head in dorsal view transverse ( Fig. 13 ), 1.75 times as broad as long, eye slightly (18:16) longer than temple, temple rounded, occiput excavated. Temporal and hypostomal carinae meeting near to base of mandible (cf. Fig. 2 ). Ocelli small, elliptic, OOL 2.7 times as long as POL. Eye in lateral view 1.6 times as high as wide and as wide as temple on its upper part, temple slightly narrowing ventrally ( Fig. 14 , see arrows). Malar space somewhat shorter than basal width of mandible. Face 2.2 times as wide as high, inner margin of eyes parallel. Clypeus 1.7 times as wide below as high medially, pair of tentorial pits slightly nearer to eye than to each other, its lower margin truncate (i.e. without denticules, Fig. 15 ).

Mesosoma in lateral view 1.5 times as long as high, polished. Pronope distinct. Notaulix evenly deep, crenulated. Prepectal carina distinct. Precoxal suture also distinct, almost reaching hind margin of mesopleuron. Areolation of propodeum distinct, areola basalis wide, pair of spiracles latero-medially ( Fig. 16 ). Hind femur 4.1 times as long as broad medially ( Fig. 17 ). Hind tibial spurs short, as long as fourth tarsomere. Hind basitarsus as long as tarsomeres 2-3 combined.

Forewing slightly longer than body. Pterostigma ( Fig. 18 ) wide, almost three times as long as wide and issuing r just proximally from its middle, r very short, 1-R1 as long as pterostigma and ending before tip of wing, 2-R1 long: nearly 0.4 times as long as 1-R1. Second submarginal cell narrow, i.e. 3-SR 0.6 times as long as r-m, 2-SR and r-m subparallel. SR1 faintly bent and six times as long as 3-SR ( Fig. 18 ). First discoidal cell relatively less high, 1-M 1.8 times as long as m-cu, 1-SR missing, 1-SR-M 0.7 times as long as 1-M. First subdiscal cell distally somewhat open ( Fig. 18 , see arrow).

First tergite ( Fig. 19 ) less broad, anteriorly parallel-sided and posteriorly broadening, 1.4 times as long as broad posteriorly, 1.7 times broader behind than basally; pair of basal keels less distinct and posteriorly merging into striolations, pair of small spiracles before middle of tergite. Second tergite just longer than third tergite, border between them almost indistinct. Tergites beyond first tergite polished.

Antenna brown. Head black, mesosoma and first tergite blackish brown, metasoma brown. Palps and mandible pale yellow, clypeus brown. Tegula brown, parategula brownish yellow. Legs yellow, coxae + trochanters straw yellow, distal two-thirds of hind tibia brown. Wings subhyaline, pterostigma opaque brown, venation light brown.

D e s c r i p t i o n of the male paratype: Similar to the male holotype. Body 2 mm long. Antenna with 22 antennomeres. Forewing: 1-R1 slightly shorter than length of pterostigma. First tergite almost 1.5 times as long as broad posteriorly. Hind femur 3.9 times as long as broad medially.

Female and host unknown.

D i s t r i b u t i o n: Honduras.

T a x o n o m i c p o s i t i o n The new species, Diospilus subfuscus , is near to D. podobe PAPP ( PAPP 1995: 106) , the male of the two species are distinct by the following features:

1 (2) Forewing: pterostigma wide, 2.6 times as long as wide, r relatively short; second submarginal cell wide, r-m slightly longer than 3-SR; 2-R1 short, 0.25 times as long

as 1-R1; first subdiscal cell distally closed (Fig. 12, see arrows). First tergite evenly boadening posteriorly, just broader posteriorly than long, longitudinally sculptured

(Fig. 9). Propodeum: areola basalis less wide, its carination as in Fig. 10. Hind femur

3.3 times as long as broad (Fig. 11). Antenna with 28 antennomeres. Head, mesosoma and first tergite black, metasoma dark brown; legs pale yellow, hind tibia

+ tarsus light brownish.: 3.7 mm. Costa Rica, Honduras............ D. podobe PAPP 1995

2 (1) Forewing: pterostigma less wide, three times as long as wide, r relatively long; second submarginal cell less wide, r-m 1.6 times as long as 3-SR; 2-R1 long, 0.37

times as long as 1-R1; first subdiscal cell distally open ( Fig. 18 , see arrow). First

tergite less broadening posteriorly, 1.4 times as long as broad posteriorly, striolated

( Fig. 19 ). Propodeum: areola basalis wide, its carination as in Fig. 16 . Hind femur 4.1

times as long as broad ( Fig. 17 ). Antenna with 21-22 antennomeres. Head black, mesosoma and first tergite blackish brown, metasoma brown; legs yellow, hind tibia

+ tarsus brownish.: 1.9-2 mm. Honduras....................................... D. subfuscus nov.sp.

The new species is also near to D. adustior nov.sp., the males of the two species are distinguished by the features keyed:

1 (2) Forewing: SR1 reaching tip of wing, 2-R1 very short: 0.1 times as long as 1-R1 ( Fig. 6 ). Propodeum: areola basalis narrow ( Fig. 4 ). First tergite relatively more broadening posteriorly, slightly (1.1 times) longer than broad posteriorly ( Fig. 7 ).

Hind femur fairly thick, 2.8 times as long as broad ( Fig. 5 ). Temple in dorsal view

slightly more rounded ( Fig. 1 ). Face hairpunctured. Hind tibia entirely brown.: 2.1

mm. Honduras..................................................................................... D. adustior nov.sp.

2 (1) Forewing: SR1 ending before tip of wing, 2-R1 long: nearly 0.4 times as long as 1-R1 ( Fig. 18 ). Propodeum: areola basalis wide ( Fig. 16 ). First tergite relatively less broadening posteriorly, 1.4 times as long as broad posteriorly ( Fig. 19 ). Hind femur

fairly thin, 4.1 times as long as broad ( Fig. 17 ). Temple in dorsal view slightly less rounded ( Fig. 13 ). Face polished. Hind tibia distally brown.: 2 mm.
