LITUS Haliday, 1833 View in CoL View at ENA

( Figs 519–544 View FIGURE 519 View FIGURES 520–524 View FIGURES 525, 526 View FIGURE 527 View FIGURE 528 View FIGURES 529–534 View FIGURES 535–539 View FIGURES 540–544 )

Litus Haliday, 1833a: 269, 1833b: 345 View in CoL . Type species: Litus cynipseus Haliday, 1833 View in CoL , by monotypy.

Neolitus Ogloblin, 1935a: 60 View in CoL . Type species: Neolitus argentinus Ogloblin, 1935 , by original designation. Synonymy by Triapitsyn & Berezovskiy, 2004a: 3.

Diagnosis. Body length 265–645 μm. Funicle 6-segmented ( Figs 519 View FIGURE 519 , 524 View FIGURES 520–524 ); mandibles crossing when closed, with 2 subequal teeth ( Fig. 534 View FIGURES 529–534 ); vertex with lateral ocellus at posterolateral angle, forming an obtuse ocellar triangle ( Figs 523 View FIGURES 520–524 , 532 View FIGURES 529–534 ); head posteriorly without evident sulci but occiput separated from gena/postgena by slight change in sculpture lateral to dorsal margin of foramen ( Figs 521 View FIGURES 520–524 , 530 View FIGURES 529–534 ); mesophragma projecting into gaster ( Fig. 535 View FIGURES 535–539 [gaster broken off]); propodeum posteriorly with a short but wide ring-like nucha (neck) separated from rest of propodeum by a distinct narrowing ( Fig. 535 View FIGURES 535–539 ); petiole apparently narrow ( Fig. 541 View FIGURES 540–544 ); metasoma smooth, laterally compressed, with gt 1 cynipid-like, much the largest tergum ( Figs 528 View FIGURE 528 , 540–542 View FIGURES 540–544 ).

Discussion. Litus apparently belongs to the Alaptus group of genera together with Alaptus , Callodicopus , Dicopomorpha and Dicopus but is also similar in petiole structure to the Camptoptera group of genera. It is perhaps most similar to Callodicopus in having a compressed gaster, higher than wide, but differs in the back of the head not having any distinct sulci, funicle 6-segmented, and gt 1 the largest tergum.

Nearctic hosts. Unknown. An extralimital host is for the type species, reared from Ocypus olens (Müller) ( Coleoptera : Staphylinidae ), which also occurs as an accidental introduction in California.
