Diospilus adustior nov.sp. ( Figs 1-7 View Figs 1-7 )

M a t e r i a l e x a m i n e d: Male holotype: Honduras, Yoro, Palo de Comba , 15$11’N / 87$39’W, taken with Malaise trap in mid-elevation secondary forest, 31 August 1995, leg. R. Cave. Holotype is in good condition: glued on a pointed card by its right meso- and metapleuron.

D e p o s i t o r y: Holotype is deposied in the Zoologisk Museum, Lund.

E t y m o l o g y: The name "adustior" of the new species refers to the brown ground colour of the body.

D e s c r i p t i o n of the male holotype: Body 2.1 mm long. Antenna as long as body and with 24 antennomeres. First flagellomere twice and penultimate flagellomere 1.8 times as long as broad, flagellum attenuating. Head in dorsal view transverse ( Fig. 1 View Figs 1-7 ), twice as broad as long, eye somewhat longer than temple, temple distinctly rounded, occiput weakly excavated. Temporal and hypostomal carinae meeting near to base of mandible ( Fig. 2 View Figs 1-7 ). Ocelli middle-sized, elliptic, OOL four times longer than POL. Eye in lateral view 1.5 times as high as wide, just wider than temple (15:14), temple somewhat narrowing ventrally ( Fig. 3 View Figs 1-7 , see arrows). Malar space somewhat longer than basal width of mandible. Face 2.3 times as wide as high, inner margin of eyes parallel. Clypeus twice as wide below as high medially, pair of tentorial pits somewhat nearer to eye than to each other, lower margin of clypeus truncate (i.e. without denticules, cf. Fig. 15 View Figs 13-19 ). Head polished, face with hair-punctures.

Mesosoma in lateral view 1.5 times as long as high, polished. Pronope invisible (head concealing pronotum due to the mounting position). Notaulix evenly deep, crenulated. Prepectal carina distinct. Precoxal suture fairly wide, crenulated. Areolation of propodeum distinct, areola basalis narrow, pair of spiracles latero-anteriorly ( Fig. 4 View Figs 1-7 ). Hind femur thick, 2.8 times as long as broad medially ( Fig. 5 View Figs 1-7 ). Hind tibial spurs short, as long as fourth tarsomere. Hind basitarsus somewhat shorter than tarsomeres 2-3 combined.

Forewing as long as body. Pterostigma ( Fig. 6 View Figs 1-7 ) less wide, 3.6 times as long as wide and issuing r proximally from its middle, r very short; 1-R1 reaching tip of wing, 2-R1 very short: 0.1 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 parallel, SR1 faintly bent and five times as long 3-SR ( Fig. 6 View Figs 1-7 ).

First discal cell relatively high, 1-M twice as long as m-cu, 1-SR indistinct, 1-SR-M onesixth shorter than 1-M; first subdiscal cell distally closed ( Fig. 6 View Figs 1-7 , see arrow).

First tergite broad, slightly (1.1 times) longer than broad posteriorly, twice broader behind than basally; pair of spiracles before middle of tergite, pair of basal keels near to lateral margin of tergite, hind part of tergite with fine striolation ( Fig. 7 View Figs 1-7 ). Tergites 2-3 equal in length, together with further tergites polished.

Scape and pedicel yellowish, flagellum brown. Head blackish brown, mesosoma dark brown, metasoma brown. Palps and mandible straw yellow. Clypeus brown, face dark brown. Tegula yellowish. Legs yellow, coxae and trochanters straw yellow, hind tibia entirely brown. Wings hyaline, pterostigma brown, venation light brown.

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 adustior , is near to D. podobe PAPP by their dark body colour and broad first tergites ( PAPP 1995: 106), the male of the two species are distinguished as follows: 1 (2) Head in dorsal view less transverse, 1.75 times as broad as long, eye somewhat shorter than temple (Fig. 8). First tergite somewhat broader posteriorly than long, 2.2 times broader behind than basally (Fig. 9). Propodeum: areola basalis wide, its carination as in Fig. 10. Hind femur 3.3 times as long as broad medially (Fig. 11). Forewing: pterostigma wide, 2.6 times as long as wide, SR1 approaching tip of wing, 2-R1 long: 0.25 times as long as 1-R1 (Fig. 12). Antenna with 28 antennomeres. Head and mesosoma black.: 3.7 mm. Costa Rica, Honduras................ D. podobe PAPP 1995 2 (1) Head in dorsal view transverse, twice as broad as long, eye somewhat longer than temple ( Fig. 1 View Figs 1-7 ). First tergite somewhat longer than broad posteriorly, nearly twice broader behind than basally ( Fig. 7 View Figs 1-7 ). Propodeum: areola basalis narrow, its carination as in Fig. 4 View Figs 1-7 ). Hind femur 2.8 times as long as broad medially ( Fig. 5 View Figs 1-7 ). Forewing: pterostigma less wide, 3.6 times as long as wide, SR1 reaching tip of wing, 2-R1 very short: 01 times as long as 1-R1 ( Fig. 6 View Figs 1-7 ). Antenna with 24 antennomeres. Head and mesosoma brown.: 2.1 mm. Honduras............................................. D. adustior nov.sp.
